Here's the camera kit, CAD$32 including delivery from China (eBay link from seller coolintshop). There's also (not shown) a double-sided sticky gasket, and nut/washers for the mounting post on the camera. My camera is white, but the same all-metal model can also be had in black or chrome.
Also note that there is no need for a special camera with built-in illumination LEDs: the car has those already, they're called "backup/reversing lights".
