The side camera on our rig apparently was not sealed very well and water got inside. Looking for a new one, hopefully one that will be a close if not exact replacement. The current one has a 5 pin plug and is 3 inches long x 2.5 inches wide.
Photos attached (I hope)
CAMPING(n. CAM-ping) - When you walk the dog in your pajamas with a cup of coffee in one hand and a bag of dog poop in the other while striking up a conversation with total strangers.
The cameras themselves typically are sealed and waterproof. The housing or protective outer lens leak and can be re-sealed. If the camera works but blurry this is probably the reason why. If it comes apart it can be re-sealed. Cheaper than new camera.
