Introduction
The SIAMvvm system was designed to assist operators of low profile LHDs, in manoeuvring their vehicles inside the mine's drifts. The system consists of two compact cameras, one at the front end of the vehicle and another at the rear. The cameras allow the operator to view the right side of the LHD, increasing his visibility while driving.
The monitor enclosure is installed into the dashboard of the vehicle. It is composed of a color monitor, “Forward” and “Reverse” manual override push-buttons, and a video switching relay. This relay is controlled by the vehicle transmission “Forward” and “Reverse” signal. The push-buttons are also illuminated so as to indicate which camera is in use. The indicator lights are controlled by the vehicle transmission or by the manual override push-buttons.

Adjustment potentiometers are available inside the monitor enclosure to adjust the Colour, Tint, Brightness and Contrast of the LCD monitor.

Two types of camera are available, Color or Black & White. The cameras are fitted into a rugged housing especially designed for harsh environments. The rugged housing protects the camera and the lens from debris and dust.

The camera cable harness includes a DC power cable and a coaxial cable. PMA flexible conduits protect both cables. Heavy-duty circular connectors are used at both ends to secure the connection. The cameras are equipped with a wide-angle lens so that the operator has a broad view of the drift.

The cables are available in different lengths to fit any LHD or truck
