Long Range Surface Transmission System - Digital MicroVision

More Pictures Brochures Manuals

The CDL Digital MicroVision (DMV) is a next generation surface video transmission system which uses the latest CODFM digital coding techniques to achieve many advantages over traditional video transmission methods.

A greatly enhanced picture is produced at the receiver end. Ghosting effects, often seen on analogue systems are eliminated and the system gives longer range while using less power.

Up to 8 DMVs can be used in the same area and both PAL and NTSC are supported. The system comprises Tx and Rx heads, a Transmitter control box and Receiver control box with               integrated 5.6" display. All housings are ruggedized machined aluminium. A range of antenna options are available allowing increased range in both directional and Omni-directional        configurations.
