Hi
A rear camera would only be of use to me if I could see what is going on "live" .. In other words a rear camera that records but also is a rear view camera, of particular use when backing up.
Here's why .
Several years back I pulled into a driveway at night to drop the wife off to visit her friend. I drive a Chevrolet Suburban which is a large vehicle.
When I was in the driveway, unknown and unseen by me a woman pulled in behind me and parked very close to me. She got out and also went up to the house. Her car was a small black car, her lights and everything were turned off. I did not see her arrive at all, she had zipped in so fast.
My engine was still running and my tail lamps were lit, one would think it was obvious I may be planning to leave
So in the night she had a small black car parked so close to my Suburban I could not see it in my mirrors. Not a good situation.
Anyway to make a long story short, I looked in my rear view mirror and 2 side mirrors and saw nothing so I backed up . When I heard the crunch I stopped and got out to look. It was not a pretty sight.
Especially since she had just purchased her car brand new from the dealer 1 week before. .
I had to pay for the repair to her car. (I also offered to pay for psychiatric treatment for her but she refused).
The next day I went and had a device installed which would warn me if anything was in close proximity to me when reversing. I called it my "Anti Idiot" device.
How many times has any one of us tried to reverse in a public parking place (or private as happened to me above) only to see someone walk directly behind you or drive behind you even when you are in motion?
That is why I would like a rear dashcam but one that also will relay what is happening in realtime in a viewer somewhere where I can see it.
These may be a bit expensive but certainly a lot cheaper than paying for some idiots repair job or medical expense.
