These were an upgrade to an older Night Owl System so installation was a breeze as basically I just changed the cameras and the DVR. The video is nice and the ability to do human vs vehicle vs face detection is very helpful at cutting down false alerts that you used to get from the "pixel change" motion alerts of the older systems.
My biggest gripe with this product is the app. It's slow to load, and some of the features for iOS don't work.
-For example the do not disturb function is hit or miss as I set a time only to fin out that it does not work.
-There is no snooze function for motion, so you have to turn off notifications if you are going to be in an area outside for a while, be prepared to be constantly bombarded with notifications.
-The sound warnings, while effective are all or nothing. They constantly go off when motion is around and repeat the same phrase over and over. Would be nice to have a chirp option that let's someone know there are cameras but does not constantly shout out Smile you are are being recorded.
-It would also be nice if there was greater integration into the smart home universe. For example, IFTTT integration would be amazing such that you could trigger lights to come on inside the home if a human is detected, etc. None of that is possible currently.
