Peeps,
The camera is tiny. It's about 2cm long and just over 1cm in diameter. The camera on the screen is excellent and it even senses when there is low light conditions and turns to black and white and looks like a night vision camera
The camera is linked up into the reverse light and comes on and goes off automatically when reverse is detected, so you cannot use it when travelling forward.
It definitely takes a week or so to get used to, but it does stop you hitting objects and makes parking up to objects easy. You can also see kiddies and narrow poles which a reverse detector may or may not see.
The lens is a "fisheye" lens and gives you a wider rear view than you would normally get from a normal camera. The screen is also a mirror view of what is behind you...so left is left and right is right. On some camera's the opposite applies, but the way I have it is the most natural.
I thought about having the camera above the reg plate, but it would have meant drilling through the bumper and taking the bumper off to fit it. I was shown one like this and it was more noticable than where I decided to have it located.
