Safer reversing

Guidelines that move with you
Dynamic reversing guidelines are generated by the camera itself, so they appear on any compatible screen as soon as you select reverse. A built-in G-sensor adjusts the guidelines as the vehicle moves, so parking and hitching up are easier to judge.

Made for corrugations and wash-downs

Frequently asked questions
Does it come with a screen?
No. This is the camera on its own (standalone). You will need a reversing monitor or head unit with an RCA (composite) camera input to view the picture.
What video signal does it use?
It is an analogue composite (CVBS) camera with NTSC/PAL output at 800 TVL and an RCA video plug. Most aftermarket reversing monitors and head units with an RCA camera input will work. The Hema HM-MNT uses 6-pin camera connectors, so it needs an RCA adaptor. Not sure? contact our team before you order.
Will it work on a truck or a 24 V vehicle?
Yes. It is rated for 12 V and 24 V systems, so it suits cars, utes and commercial vehicles.
Is it waterproof?
Yes. The housing is rated IP69K, which means it is sealed against dust and high-pressure water. It operates from -30°C to 85°C.
How is it wired?
Power comes from the reversing light circuit: red to the reversing light positive and black to earth, on 12 V or 24 V. The 6 m cable runs the video signal to your screen.
