Cameras either record everything or nothing. If one is triggered it delays the other one which doesn't help me catch surrounding. Car pulls up but out of the frame I can't see who gets out in other Camera due to the delay. It says it has sound but I've not ever been able to get the sound to work. And my number 1 # it does not notify my cell phone when power has been disconnected so if a kid unplugs it or even if I just lose power a day can go by without me knowing! Wish I had gotten a ring!
