I am thinking of buying this one https://www.canadiantire.ca/en/pdp/...
It is coming up on sale for half price, at $100. Before you compare that to US prices, remember that stuff, in general, is more expensive in our semi-socialist country.
It is a wired camera and I don't mind running a cable from the rear license plate to the cab. I expect the wired cameras to work better than the wireless ones.
