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.
