Yes, I left my doors unlocked and lapsed in my nightly routine to lock all the vehicles before bed. Please don't hesitate to suggest setting adjustments. I havent made any setting changes other than making sure the cameras are secured on my network. Cams are Dahua HDW5231R-ZE. Typically the lighting for the flag has that one running color at night but i adjusted some things for a b/w view to see the difference. I'm an amateur and still learning about cameras. They stole an old tablet that my kids used.
