Best part of the camera, it's simple. Nothing complicated to do other than putting the batteries in an mounting it where you want. The whole system was really easy to put together and make everything work. I suggest put all the cameras and base together on your tv hdmi connection and router your network is on.This way you can insure everything works, pairs, adjusts, records, and scare people who don't know you have it on and hidden. The only thing I don't like, it's not 4k like the ones with my NVR. Didn't think I would complain about HD camera resolution, but 4k is blow'n 1080p away. Once you get everything paired, and it all works doing the items like brightness, recording, activating by movement, points where it should, then wait a day before using the cameras in the location you've picked.. . You can install and run the app while the system is connected to the tv. And let it run for 24 hours, for a on test to see what happens to everything before mounting it. Once the app is installed, and the phone is going to be used for controlling the system, you will have to reboot the box, for it to have the phone as primary controller. I put my cameras on a 2-3' wide board 10-12 inches long. This lets you aim the camera when holding the phone and aiming the camera for the best coverage.. Leave the cameras in place an go look using the tv. I did this with one screw holding the board to temp mount it. after watching it for hours, 3 of the 4 were moved several feet. Don't forget the power supply can't be left out in the weather, so get a 12v power cord that can reach it and tape up the connections. Put all your cables under cover to stay dry, then use a power strip or 2-6 way plug adapter. It was harder to place the 4k cameras than the add on. It came several days later. Install the batterys, it turns on itself, install to system with app, make sure everything works and camera starts recording and adjusts like it should, then go find a place to put it. I painted mine a camo brown, then put outside were no one would notice high up to get coverage of yard and house. It's been a week, still over 70% battery using 4 of them. This system, a bluetooth NVR with 1 TB drive and 4 cameras @4k resolution is really simple to use. The add on cameral, with batteries is idiot proof. If they were 4k, and used batteries like the one I have, it could be a kickass super simple setup to use and move around where ever you wanted.

It fulfills it purpose of being a completely wire free camera that you can place anywhere within the range of the wireless recorder. Good features and sensitivity, and the ability to "Speak" through the Camera speaker and "Listen" using the Mobile Application. One Caveat though is that while they say "Up to 6months of Battery life" that must have been in an empty room with zero "Triggers" on the camera, since I have this configure to only trigger on "Human" and "Face" and with 10-12 Triggers per day, the batteries only last 2 weeks before needing a recharge. However, knowing that was likely, I also bought the wall charger that comes with a spare set of batteries so that you can just swap the dead ones with the fresh ones and put the others back on the charger for the next time.
