Terrible, stopped working after 12 months. Also a pain to install.
Looks like the camera maybe the problem.
hard to believe that Jaycar don't know this thing is a dud.

Bought this 2 camera wireless system for my horse float. Worked ok for a year then it had to be paired again as the rear cam stopped working. Both cameras worked again for a while then the rear cam became intermittent. I'm over it. Now neither cam will pair. Not really fit for purpose.

I have used this Long Range Jaycar reversing camera kit for 15,000km over 12 months.
It has worked very well over rough gravel roads, and on the highway.
Display could be better but it has done what I want, even at night.
I do remove it when stationary so it has not been subjected to weather 24/7.
Works better than my previously hard wired camera and display.
I would definitely replace with another one.

We were told that it would work on our bus after many visits to Jaycar and auto electrician it is a no go. It has cost so much would never recommend it. This is no good the camera keeps flashing on and off even when the bus is still. The only place it works is through the water view tunnel.

Installation on an Hyundai IX35 relatively easy. Was never the best as it often picked up other cameras and flickered from its own camera. Stopped working after 12 months (just out of warranty) - believe it is the transmitter (as per other reviews). Screen still has power.
Believe hard wired is the way to go.

Installed on back of camper trailer and despite trying different locations and the relatively short transmitting distance, it was useless. In fact it was dangerous with the intermittent flickering on and off of the screen as the signal strength vatied. Changing light conditions rendered it unseeable in simple reversing operation.

When installed in a car to a caravan, the wireless reception by the car display from the van camera transmitter is so weak the static or noise bars flickering around the display make it useless. I took the display into the caravan and plugged it into a 12v van socket, and the display was OK at a distance of 2 meters, step outside the door of the van and it was very bay reception.
THUMBS DOWN.

Had a auto electrician install this unit on car and caravan . Found car camera just acceptable still with interference but no or very poor reception from caravan mounted camera with screen very hard to see, they tried adjusting aerial position and no good . I am having a cable linked camera's installed, it just doesn't do the job advertised [80m range?] and it's going to cost me a fortune in labour .

Camera from rear of vehicle works fine. Unfortunately the camera mounted on the back of caravan is a complete dud. After numerous attempts to get it to work made a phone call to the importer and was told that the caravan is interferring with the signal and it will never work so after spending $254 for camera kit and then paying for installation we have something that half works offered refund but nothing towards installation. Very disappointed.

Have had multiple problems. Transmitter failures x 2. Replaced on warranty. Now out of warranty and another transmitter failed. Replaced at my expense. Then the monitor failed. Replaced at my expense. Now this monitor has failed after 2 months and I find out it is now obsolete. I'm so annoyed.
