Update: Patches applied automatically have corrected both issues – system works great now.Great concept, great price point, but sadly the software (and maybe the hardware) is buggy. The Synch module goes offline intermittently requiring a reboot to come back on line. There is also an apparently known issue with live view recording despite the settings. It just does not record, or not, per the settings. I am a networking expert and will say support is nice and available, but not technical. Their explanations include “move the synch module to within 6 feet but not too close to the router”. That is simply technically illogical, but I did try it anyway (by the way blink would be communicating with an access point”, not a “router” – my support guy didn’t understand the difference). They said Mesh networks (which I run) have issues, so I went and setup a completely different dedicated non mesh WIFI network just for Blink – Mesh was and is not the issue in my opinion. (I run commercial grade AP’s and router with a solid fast Cable Internet link at home, because that’s what I do) I went ahead and installed a smart plug to reboot the thing so I can restart it without having to physically unplug it and plug it back in. There is no ability to reboot any of the components without either unplugging (synch) or pulling the batteries out (cameras – which is obviously inconvenient and ridicules). I’m hoping the issues get resolved or I’ll probably end up installing more “real (7×24 recording)” IP cameras. NVR’s are available (no subscription – I run one) but the cameras are comparably expensive compared to Blink and Blink’s ability to run off batteries is very cool making installation (and repositioning) a breeze. In summary, guys, please make the product work as advertised and it would be a 10 for the application and purpose.

I ordered a 4 camera system, easy battery install, but I didn’t happen to notice any written instructions that came with, perhaps it was online, but it wasn’t hard to figure out. Easy install, great pictures and videos. However, the batteries in 2 of the 4 cameras only worked for 2 days, 1 died the day after set up and the other died the next day. I’m sure they had been sitting in a warehouse for who knows how long before they were sent to me, just plan to set your schedule times to promote battery life.

After about 3 weeks of use: almost perfect camera system. Does what it says and is very dependable. Does not disconnect. Image quality is really high. Night mode provides a very detailed image (albeit black and white). I am still in the trial period for the cloud storage so I cannot comment on how it handles the USB-stick operation and limitations.Some small cons:- The auto night mode does not activate when it actually should, especially if your video frame includes some brightly lit windows or doors. It thinks that there is enough light to remain inactive but it is confused by the window light and the majority of protected area is very dark. It can be switched on manually but who remembers to switch it back and forth. Some solutions if Blink developers read this: add option to enable night mode based on geolocation and night/day times, or do not decide based on a sensor but by analyzing a video frame and checking if the dark area exceeds a certain percentage. Etc.- Sometimes even smoke or steam from a gas boiler is detected as “movement”.- When you activate Live View on a camera, you get a “Continue ?” prompt about every 30 seconds. I understand the rationale since the video feeds probably go through Blink’s infrastructure, but it’s annoying nonetheless. But to be honest, I rarely need to watch more than 30 seconds. One minute would be nicer though.All in all, I am not really complaining. The system is very well integrated, easy to install and does its job properly.

I bought these to add yo my existing blink system. They are not good. They go to “Camera Offline ” almost every other day or maybe every three days. VERY FRUSTRATING, having to climb up and pull the batteries and go through the reconnect process. Will be trying a wifi extender, and that doesn’t work… I don’t know. I’ll try to return them. Other cameras that have a weaker signal and are much further from the router and sync module haven’t failed yet!!!UPDATEThis system is not good. Now the sync module disconnects in the middle.of the night. Says no internet. However everything else in house that’s connected to wifi, including safety electrical sensors that depend on wifi, work continuously. Only the blink… then, after reconnecting yet again, ll the outdoor cameras connected to this system fail, will not load a snapshot or video. “Camera busy”, or “failed to perform command ” is all get. Of I were still iny return widow,nid return the while thing. I have a total of ten cameras. That’s alot of money. I’ve never had any internet issues with my devices, just blink. Even the antique camera these were designed to replace were better, and they only worked half the time! Shm… so disappointing, and expensive. I cannot afford to go and start buying a new camera system, so I’m kind of stuck with this junk. I had such high hopes, but alas, these ceramic and the whole system just suck.Their customer service says they are sending replacements to me, for the ordinal three I have complained about (2 outdoor 4 and a hardwired floodlight camera). But I honestly don’t know if it’s even worth the time and effort ot takes to drag up the ladder and replace them. Especially since now the dang sync module is deciding to tale naps at random times.Please use caution when shopping for a wireless system, as these are junk in my experience. Fancy expensive dummy cameras for visual deterrence only.If you can afford it, go with a hardwired system. Call around and price it out. Then compare to the cost of the two systems (and don’t forget you’ll need to add 10 bucks a month for the blink cloud service, otherwise your basic features like live view won’t work.Update 3:So these are still going out randomly at least once a day. At least one camera, floodlight or the sync module itself (which knocks out ALL your outdoor cams) has an issue daily. I have upgraded my internet and wifi equipment in an effort to ensure high connectivity. The devices all show full bars for connectivity. They just don’t work sometimes. I’m paying 10 bucks a month for the service. All that’s left is issues with devices themselves. It’s quite vexing. Updates to follow as long as Amazon allows Mr to keep posting them.Still one star.UPDATE 4:So today I noticed that I’m getting push notifications to my phone about specific cameras detecting motion. However there is nothing in my clips library. Then, say several hours later or even the next day some random clips will appear- the ones missing I mentioned above. SMH…. so now there’s this issue. THEN, later on today two cameras just randomly went offline. As I went to once again reconnect them, they came back online. Now, that’s a first- they usually don’t come back online their own…..These things… don’t buy these things, no matter how great the deal is!!!UPDATE 5:So this week was as disappointing as last week. Once a camera said it was having trouble with wifi(?) Which was a new and exciting error message I hadn’t yet seen. Upon looking at the signal strength the wifi was full bars, but the connection to the sync module was one bar! This isn’t even the most obstructed or most distant camera! After I backed put of the app and went back in, the signals were back at full bars.There were a few times the doorbell cam went offline, and a few times the outdoor cameras went offline. It’s all just such a waste of nonrefundable money that one can only shake there head at this. I find it hard to believe all ten of my devices are bad. They were bought at different times… my wifi was upgraded along with the equipment. Just another week of anger filled regret over over buying BLINK. don’t do it would continue to be my advise. If you want cameras have professional installed hardwired system with a warranty on parts and labor… longer than the 30 days Amazon gives.On a positive note I only had to restart and reset the sync module once this week… if you wanna call that positive!Update 6:Now the hardwired camera decided to quit on me. It was the one with the least issues… avoid BLINK people… if I hadn’t invested so much in this system it I would have gotten rid of it.

ALL of the Blink stuff I have ordered is getting this same review. After doing an insane amount of research for a home security camera system I settled on Blink for ease of set up and cost. In both of those areas there really isn’t a close second. As far as reliability, I’ll check in again in a year or two–but other reviews indicate reliability is good. So, good news: easy set-up, great prices, video quality is as good as any, motion sensors and other software adjustable stuff is easy to understand and do.Bad news: The system is crazy slow. I knew that going in, so it might be a bigger deal to you. I’m willing to live with it mostly–down the road I plan to put in a much faster, wired, real time system with only one or two cameras, and Blink has a new “Sync Module” that is supposed to have greater range–and maybe speed things up a bit. The slow is annoying…but not a deal breaker.It has notified me of low batteries a few times–so now I just let it go and they seem to recover on their own. I’ve also had one or two go offline and I had to reinstall them. I think there are two factors causing this, and again for the price I am willing to live with it. For one thing I have the wireless range maxed out even with an extender for my WiFi network. The other factor is it is currently the dead of Winter and cold beyond all reason. 9 degrees last night, high is 31 today. Lots of snow and wind, too. I’m harder to get along with in this weather myself, so I’ll put up with some additional problems with electronics that live outside.Bottom line? After three months I’m happy with it and I recommend any and all of the parts of the system I’ve bought. It works as advertised and it’s way cheap–including the annual subscription if you want cloud storage. I will be buying a couple more pieces soon. It is fully functional as long as you don’t need a lot of speed. I’m talking about minutes when I’m antsy and want seconds.
The Photography Hobbyist –
Overall, I’m very happy with the Blink camera system (and I’m not paying for the subscription). One of the reasons I decided to buy into this system was because I didn’t need a subscription for: 1) Live view option, which means, see the live video from the cameras any time I want via the app, from anywhere. 2) Save videos that were triggered by motion to a USB flash drive (memory stick) inside my house (not cloud only and not stored in the camera itself). Keep in mind, most of my comments here will be related to using the system without a subscription, but I’ll comment on the differences where possible. Also, my comments may be a little more technical than most people would like, but for anyone interested, I’m being as detailed as possible :-) These comments are relevant as of Feb 2024 (the date I wrote this review).Viewing/Storing Your Videos: During the trial subscription period when I could view my motion-triggered saved videos in the cloud, I noticed the videos load/play quicker than if you’re accessing the videos stored on the USB flash drive in the Sync Module 2. Anyway, not a big deal, but it’s a difference. You need to provide a USB flash drive to plug in to the Sync Module, but those are very cheap these days and a 128GB drive will give you TONS of storage for videos since the file size of the videos is not very big. Also, with the cloud subscription there’s a thumbnail for each video saved, which can be helpful in finding important videos if you’re trying to find one with people in it, rather than a video triggered by a dog. Without a subscription, there’s no thumbnail on the saved videos which you view in your app, and it takes several seconds for them to load/play in your app, but it’s bearable. The nice thing is, if you don’t have a subscription, the videos save to your flash drive/memory stick in the Sync Module 2 immediately after the recording is finished. If you have a subscription, the videos only download to your Sync Module’s USB flash drive once per day, at night (as I understand it).Sync Module 2 & Wireless Signals to Wi-Fi & Cameras: The Sync Module is required for the cameras, but you get one of those if you buy a package, like I did. I bought the bundle that included two Outdoor 4 cameras, one video doorbell and the Sync Module 2. It’s important to know the Sync Module and the cameras have TWO wireless signals. One that needs to connect to your home (or business) 2.4GHz Wi-Fi network and one that is only for use by the Sync Module and cameras and that signal is a ‘Low-Frequency Radio’ (LFR) signal. It does not have 5GHz, but you don’t want that anyway because the 5GHz signal is weaker than 2.4GHz signal. The Sync Module is where you connect a USB flash drive (memory stick) to save your videos if you’re not paying for a subscription (and also for once-daily backups of your videos if you ARE paying for a subscription). PLACEMENT OF THE SYNC MODULE IS IMPORTANT! Remember, it has TWO signals. It needs to be placed in an area that has a good signal to your home/business Wi-Fi AND so that it also has a good signal to all your cameras (if you have them spread out in different areas around your home or outside your home). To give you some perspective, my house is a single-story ranch style house (around 1,700 sq ft) and I have a camera outside on each wall (each wall is brick). I was able to place the Sync Module and my Wi-Fi access point in the center of my house. Even in this central location, I have one camera (the video doorbell, about 38’ away from sync module and Wi-Fi access point) that has only 2 to 3 bars (out of 4) for the Wi-Fi connection but usually 4 bars for the Sync Module connection. Long story short, make sure you place the sync module, your Wi-Fi access point and the cameras so they all connect to each other with as strong a signal as possible for best performance/reliability. It worked out well for my house, especially since I have flexibility on where I can place my sync module and home Wi-Fi access point and the technical knowledge and tools to move it wherever I needed it.Outdoor 4 Camera: The image quality/exposure for these cameras is very good. The nighttime IR (infrared) view is very good also (it will appear like black and white footage). The coverage of the IR light when it’s dark is also very good and has better coverage than I would have expected. I have motion-triggered flood lights outside my house anyway, so if my lights are triggered, the camera may not use IR because it sees enough light (at that point it will record normal video in color just like it does during daylight). I bought 25 ft long third-party USB-C cords with a power supply to use as the power source for my Outdoor 4 cameras so I never have to replace batteries and so I can view live video from the cameras as much as I want and also have the infrared light set to High without impacting battery life, because there are no batteries to worry about :-). I don’t know if it’s different WITH a subscription, but the longest period you can record when the camera is triggered by motion is 60 seconds. For the video doorbell the max record time per motion trigger is 30 seconds, just so you know. Regarding the power, I drilled a hole in the bricks of my house (in the mortar actually) to feed power to my Outdoor 4 cameras. One camera is directly under a soffit, so there’s no danger of rain getting in there where the power cord connects (but the cord I bought is weather sealed anyway, not a normal USB-C cord). The other camera is mounted under a third-party security camera cover to keep the sun from beating down on it all summer (it’s on a south wall) and to keep rain off it, just in case…because again, I decided to power this one by a cord that plugs into the back of the camera instead of using the batteries). The included mount is very nice and flexible. If you mount an Outdoor 4 camera under a white security camera cover like I did, you may need to paint the underside of that cover with flat black paint because at night (in my case) the infrared light reflected off the underside of the cover/shield I’m using over my outdoor 4 camera and that made the video made difficult to see clearly. Daylight videos were unaffected, it was just at night in low light when the IR light was active for video recording that was a problem with that aftermarket cover I bought.Doorbell Camera: For the video doorbell the max record time per motion trigger is 30 seconds. Why, I don’t know. Technical limitations? The Outdoor 4 cameras can record 60 seconds of motion triggered video. The wireless signals for the doorbell camera seem to be a little weaker than the outdoor 4 cameras. One big disappointment is that the video doorbell camera can NOT be powered by your existing doorbell power wire. My old Skybell brand video doorbell CAN be powered by the doorbell wires, so it’s a bummer that Blink can’t do the same. You can connect your existing doorbell wires to trigger your indoor doorbell, so that’s good…but like I said, you can’t use that wire to power the video doorbell. I confirmed this with Blink tech support. I hope they have a new version in the future that is able to be powered solely by the doorbell power wires, but for now, I have to keep batteries in it. The video doorbell device has a weaker infrared (IR) light than the Outdoor 4 cameras and lesser quality video than the Outdoor 4 cameras, but overall, it’s good (especially during daylight hours). The included mount is very nice and easy to install.Motion Triggering of Videos + Privacy: The settings/customization for when motion triggers video recording is very good. You have the option to block out as much of the scene as you need to to prevent unwanted triggering of video recordings, such an area of the scene where tree limbs often blow around or something like that. For privacy, you have the option to block out 2 custom size areas in the scene you select for privacy reasons so that area in the video is grayed out. The selected privacy area does not trigger when motion happens in that privacy section and also, when other sections in the scene that you allow to be seen trigger video, the video that’s recorded has a gray box in the privacy section (all you see is a gray box). That’s pretty powerful and useful, if you need it. Regarding motion triggered video recording in general, I’ve noticed the cameras can accidentally trigger (record) when it’s really misty/foggy outside. If there’s a lot of mist in the air floating by the motion sensor, it can trigger a recording. Just something to keep in mind because you may need to adjust the motion sensitivity and/or ‘disarm’ the cameras for a while until the mist clears because you may be getting lots of unwanted/accidental recordings. I have mine adjusted to the point where the cameras almost never accidentally record unless it’s very misty outside, which isn’t too often where I am.Audio Quality: The microphones on the Outdoor 4 and video doorbell camera pick up sound very well. I can clearly hear anyone speaking. The closer they are, the better of course, but it’s very good. The speaker volume for the cameras is very good as well. It’s plenty loud and if anyone is nearby when you activate the camera and start speaking, they’ll hear it clearly :-)Blink App for Phone: The app you can download on your phone for managing the cameras/sync module is very nice and has plenty of options to configure/customize the cameras (motion settings, video quality, audio settings, check status, etc). The app is where you view your videos, but of course if you’re storing videos on the flash drive connected to the sync module, you can remove that flash drive and plug it in to your computer to see the video files there or make copies of the files for long-term storage…but of course you can also use the app to save a video file to your phone if you want to keep a copy of share it with someone, like the cops :-). I wish they had an app for Windows so I could view the cameras live and see saved videos on the sync module’s flash drive right from my computer, but at this point there’s no PC app. I think there used to be one?…but if there was, there isn’t one now (Feb 2024).Price: I compared the price of this system and what it can do with other systems like Ring, Nest and Skybell and at this time, the price difference is significant, in my opinion. The Blink system (and what it offers even without a subscription) is better than the other systems I checked out.

Blink makes a pretty good product and some of the issues that I have with it are something that is to be expected from any wireless camera system. When it is time to actually view the camera footage after you have been alerted, it takes a minute for the footage to come up. By this time, whatever set the camera off is gone. The motion sensors work as they should but you really have to play with the settings to keep simple leaves from setting it off. It has only happened four times in the few months that I have been using this system but sometimes cameras will randomly “go offline” and you will have to climb up, remove the batteries and put them back in to reset the camera. Not ideal in the middle of the night or a rainstorm.BUT there is some good. The sound quality on the mis and speaker is really good. The night vision is excellent and the person detection works perfectly for me.These camera system is good for added security to your home and it seems that the battery life is holding strong. be sure to just pay the cheap $10/month for the unlimited video storage with Amazon.One last thing, the size of your property and the placement of the cameras REALLY matter. Once the person that is being recorded is more around 30 ft from the camera, it gets pretty hard to recognize faces. That distance is cut in half at night.

Just received this today, and it does show an improvement on the quality. Feels and looks beefier. When updating your activity zones, there are more squares to select than the previous versions of these cameras, which I like, to fine tune the areas I want. ** And, I think the inactive zones you set up, are ‘actually’ enforced and work as expected than the older generation cameras.TIP **25 September 2023 – For those having issues about wifi signal strength, you may need to mess with the router’s settings to increase signal power. If your router is between walls, behind the tv, etc. you will see degradation in performance and responsiveness in live view. I have a gaming router set on a high shelf, because routers work best when they’re in a high spot. My cameras that are outside have no issues with Wi-Fi strength and are responsive when live-viewing.Field of view has improved significantly and you can see a large difference between versions of cameras.Good thing is that the mounts for the previous cameras WILL work on this camera. The mount it came with is an improvement to previous versions. Flat base, not cone-shaped.I’m currently trying the person detection from the trial with this camera, and will update over time on the performance.**Person Detection since having BO4 as the trial, has been great! It has significantly cut down on the amount of unwanted notifications caused by wind, car/sensor lights, animals, etc. I do feel that you can save battery life significantly, even when the sensitively is set higher. Having too many notifications does get annoying at times, but I think Blink is definitely making an initiative to make these camera a gamer-changer, while still maintaining ease of setup.Price is a tad high, but you may consider the monthly payments, which I did.**28 August 2023 – Taking a snapshot/photo capture from these cameras, at night, non-night vision, pointing in a lighted area is sharp(er), than any previous version. No images included due to security. Haven’t tried night vision alone, but I’m confident the same sharpness is applied.**29 August 2023 – The Motion Recording Types cover Person Detection and All Motion. I have one camera set with Person Detection enabled with sensitivity level at 8, and it didn’t detect me driving my car in/out of the garage. I would’ve thought Person Detection would encompass ‘some’ normal motions, but I think we must take it at face value that when set to Person Detection, it will ONLY detect persons, you don’t get the best of both worlds unless selecting All Motion. Sounds dumb to say, but though I’d make it aware. Update** On a ‘very few’ instances, this camera did detect my car entering and exiting our garage. So my thoughts originally have shifted, but I think over time with continued firmware updates, it will hone in on its accuracy.1 September 2023 – One camera fell offline/unresponsive. Suspicion is on firmware updates being applied, or, weather factors since it’s low 60° outside. No issues with home network or signal strength to camera. Will continue to monitor/self troubleshoot. **I took out the batteries, and tested them, showing still a full charge/health, and placed them back in, bringing the camera back online.4 September 2023 – One of my BO4 cameras with Person Detection enabled was at level 8 sensitivity, and on a windy day, did alert that there was a person at (insert camera name). It alerted a few times during the day (under 5 instances), but not a big deal. My guess would be that as BO4 continues to develop, the accuracy will improve in its detection.8 September 2023 – Setup of 3rd BO4 camera set in an area where there is minimal/no lights. Due to security, no images. Taking Live Photo with the IR intensity set at LOW. Some haziness/fuzziness but the area is lit up, and provides better detail than previous versions of Blink cameras. As you increase in IR sensitivity, the Live Photo (in HIGH IR setting) increased in sharpness and reduces glare and fuzziness significantly. **I placed some solar floodlights in the area of this BO4, and with low IR sensitivity and once the lights are triggered, the video capture was much sharper than previous versions of Blink cameras. I only have video quality set at normal, so I’m impressed with BO4 so far!28 September 2023 Another BO4 fell offline around 11pm. Last occurrence was due to a firmware update being deployed, so this may be due to the same thing.1 October 2023 – Installed my 4th BO4, as I’m looking at all the point of views both in the live shot and live view, it feels that it elongates everything. I know my driveway isn’t that long, but comparing it to previous generation cameras, BO4 view appears to add like 20ft+ to my driveway. I can understand the other reviews concerned about the range detection, as I do notice some times it will not catch movement, especially if I’m moving slowly or based on camera positioning, but at sensitivity level 8-9, I would like to catch movement at a farther range. As I continue to implement BO4, I will continue to observe performance.6 October 2023 – It appears one of my BO4s point toward the road at max sensitivity IS NOT catching cars passing by anymore. Seems that v13.34 that was pushed out, affected the range despite any setting changes. Not a concern (yet), but I’m hoping newer updates will fix range issues and sensitivity. **Update – camera seems to be capturing movement now at a lower sensitivity set at 6-7. May’ve been a change in traffic flow by the house, in which there may be less cars, however, will continue to observe BO4 performance.4 November 2023 – Installed another BO4 camera while also upgrading one camera with a battery expansion kit. This is specifically for BO4 cameras, not previous versions. The expansion makes this camera much heavier, however, the mounts they come with (and previous) will support the weight without the mount drooping/moving. I’m not a fan of adding more bulk to the camera. Also, this battery expansion will not use camera’s battery slots, and instead uses the expansion for 4 batteries. I would’ve preferred an integration that would’ve retained the two onboard batteries + two for expansion. Other than that, the BO4 cameras have been wonderful to use, with overall quality/sharpness. I do hope that future updates will improve motion detection and range, respectively. Nonetheless, these are worth an upgrade from previous versions.15 November 2023 – I’ve noticed recently that BO4 will notify of Motion/person and it will not record that instance. It happens sporadically, so it is a slight concern, but not enough deter me from purchasing another BO4. Over time as more updates are pushed to these cameras, I expect the overall effectiveness will improve.6 December 2023 – BO4 has been a great upgrade for my system. There are still occasions where I’ll receive a notification of movement, but does not record that moment. It’s very rare now with the update to v13.41. I still see issues regarding the sensitivity not working as expected. One camera is set at 9, toward the road, and it does not always catch cars driving by. Not a showstopper, but I can see now it’s range detection could be an issue for others. With recent Blink app updates, you now can adjust the length of video recording (previously it was adjusted by every 5 seconds), which is great! Allows for better customization for your needs. I wish this was the same for the sensitivity (0-99 vs 1-9). Overall BO4 has been accurate with Person Detection, and the subscription for Blink Plus for $10/mon, is very reasonable for any household to use to expand features.27 January 2024 – BO4 has been working exceptionally well. I still have the Blink Plus subscription to allow the Person Detection feature, and it’s accurate. There were certain instances that BO4 cameras did not record movement such as my neighbor chopping his tree down. I also noticed there were connectivity issues during that time that left a large gap in my list of recordings. Not a showstopper, but concerning for those security moments. Range also plays a factor in detection, so I continue to hope that future updates will improve this. Overall, upgrading to this camera is well worth it. Wait for the sales to get these at a cheaper price.16 February 2024 – Decided to update the Blink Sync Module because I realized I was still using the 1st generation sync module. I updated to the 2nd generation sync module, and I noticed there’s more of a delay when live streaming my cameras. I did a reboot of the sync module a few times, but I still receive a slight delay. One camera I have at a longer distance is unable to be live viewed despite Wi-Fi and sync module connection have full bars/strong connectivity. Still attempting to troubleshoot but I think something about the firmware I updated to since it’s the first time connecting. Further investigation is needed. Overall, the cameras are working as expected!18 February 2024 – Identified that the issue was NOT the Sync Module 2, and rather my own internet. Reboot modem, router and network switch, and saw significant improvement in BO4 camera responsiveness. Additionally, I will take into factor that weather was not great at the time of incident. Since this, the Blink cameras are working as intended!
Harvey W. –
Already have a 24×7 live recording IP security cameras that are hardwired to local storage all over my property so cannot comment on their ability as security cameras. My purpose for purchasing was for a decent camera setup to place cameras inside my nest boxes on the property. Something that is very difficult using physical wiring. These battery operated cameras are very small and can fit in most of nest boxes I have. Was able to get 100 percent strength of the Sync module and 100 strength connection to my WIFI on all 4 cameras that I ended up purchasing. Fairly impressive for inside a wooden box outside. I did purchase a WIFI repeater to get all at 100% signal. The live view focuses very well in the tight sizes of some of the nest boxes but the motion sense just won’t work on the smaller boxes even at the highest setting. Assume the motion is just too close to the camera to trigger properly. The larger squirrel boxes work well but the blue bird houses are basically a bust. They only seem to trigger when moving from daylight to night vision or vice versa. I have turned off the motion sense in the blue bird house to conserve battery but do live checks once in a while to see if there are any new residents. My hope is to get some fun footage of nesting birds and squirrels. So now for some of the limitations that are some what annoying. You cannot give each camera an individual schedule. Every camera attached to one sync module must be armed and disarmed all at the same time. Bummer. You cannot just click a button on the App to check and update new firmware. You must wait in line until they decide to send out the update over the internet. You cannot view any motion clips right away on a computer or Mac. You have to wait until they backup to the USB stick on the sync module and then pull and put that USB stick into your computer. That alone will make me never pay any subscription fee to blink. I am not young any more and it strains my eyes trying to see detail on a small screen. Overall they are working well for the month I have had them. The sync module once in a while briefly drops offline but assume that is firmware updates. Only happened 3 times over the month and lasts about 4 minutes or so. I have set all the video setting and IR settings to the lowest settings to conserve battery and since the action is so close to the cameras don’t need high resolution. Worth purchasing for you nest boxes but know the limitations before making your decision to purchase.
