Does anyone know if the wireless back-up camera system is a good product?

Question

Does it actually work? Is the picture clear?

Answer 1

For a car or other vehicle?

There are several - since you did not specify, then I will generalize since I have seen a couple of them being used... They are good enough for you to see if there is something behind you that should not be there. This video is not expected to be made into movies so it does not need to be perfect - but it is certainly good enough to see 1-4 feet behind you and alert you that there is something there that should not be there so STOP backing up...
