When I said I was only interested in using the camera when work is performed on our coach, its because that is the only time someone other than my wife or I are inside our motor home. And, it was during a PM service that our robbery occurred. If the camera is stolen during coach servicing, we obviously know who did it.
First and foremost, having a security camera and stickers on the doors will act as a deterrent.
The reason I want the camera to record to an SD card is we have to pay for Verizon broadband data and it is expensive. I was hoping to avoid running up my Verizon bill every time the camera is in use.
