I found out something I didn't know or hear about. Arriving home I pressed the off button on my keychain ( of course it didn't shut off) and drove into my garage. Upen exiting the car the alarm was going full bore. I pressed off and it stopped this time. The interesting part is all four cameras started recording for a LONGER time than usual. I saw myself and wife exiting car, walking about 50 feet to the front door and entering the living room. I'd guess about 3 minutes of recording. I never knew this would happen I figured the camera time would be the same mediocre time to see the UPS man's back.
