Heavy Duty & Long Lasting

The Viewtech 7" Monitor is a high quality shock resitant digital monitor built for conditions associated with vehicles. It comes with sturdy mounts and brackets and all connections are made via a wiring loom which can be fully hidden. The heavy duty camera is also built to last. Made out of cast aluminium it can handle the odd knock or two and it has a built in heater to prolong its life, this keeps moisture out and means you will never have to put up with a foggy image. The camera is also IP69K rated meaning that it can be pressure washed at high temperature.  We have this camera fitted with a high quality 700TVL low lux image sensor and this is combined with a mechanical IR filter. These two together provide an extremly crisp day time imgage and a superior night vision image in pitch black conditions.  

Connections to cameras are all made via waterproof 4-pin screw type connections and the camera also comes with a rubber cable shroud and gromet for entry through an external surface.

Wide Dynamic Input Voltage Range

Features well designed DC circuitry primarily designed for 24V systems. A wide 10V-36V input range to handle voltage drops and spikes. Each camera output has smoothed 12V supply for perfect camera operation.

Easy To Install

This kit is incredibly easy to install. All electrical contacts are done at the monitor end which includes the red '+' & black '-' connection and a third reverse light sense wire which is optional to connect if you would like the system to power up when reverse is selected. All camera connections are done out of the monitor via ONE 4-pin cable. This makes installation very straight forward and a lot easier than you think.

True Day / Night Imaging

The Viewtech VT639HD camera included with this kit has a special day/night lens.  This lens uses a special filter to automatically filter out colour distorting IR during the day but then at night alternates to produce crystal clear infrared night vision image.   This creates perfect day time colour and incredibly clear night vision. 


This system is very versatile and can be installed in any bus, truck or other vehicle. For 5th wheelers and trailer units an optional trailer coupler is also available. System is powered from 12V-24V-32V and all cables are screw connections which are all waterproof. Powering to the cameras is done automatically by the monitor regardless of the input voltage.
