SerVision MVG 400 System Guide

Installing the MVG 400 System 15

NOTE: Make sure that all installed devices are designed to function properly under mobile

conditions (temperature range, vibrations, power supply, etc), that they are all

installed in accordance with their manufacturer's requirements, and that the devices

and all cables are properly installed and firmly fastened so that they will not

become dislodged when the vehicle moves. It is highly recommended to consult

vehicle experts before installing external devices.

Connecting Cameras

Up to four cameras can be connected to the MVG 400. If the cameras have PTZ controls for

remote aiming and zooming, and the PTZ protocols they use are supported, the control cables

can also be connected to the unit.

Any PAL or NTSC video camera with a composite video output can be connected to the unit.

The video inputs of the MVG 400 unit may require either a BNC or a Mini-DIN connector,

depending on the options selected when the unit was purchased. A cable with a composite

video connector on one end, and a compatible male connector (BNC or Mini-DIN) on the

other, should be used to connect each camera to the MVG 400.

Cameras that are connected to the MVG 400 can receive their power from the vehicle battery

via the MVG 400 unit. Cameras that use Mini-DIN connectors receive their power via the

same cable through which they transmit their video output to the unit (through the Video-In

connectors on the rear panel of the unit). Other cameras require an independent power supply.

These cameras can receive power via the 12 VDC connector on the rear panel of the unit.

However, bear in mind that the unit can supply a maximum of 500 mA of power. If the

devices connected to the unit require more than this amount of power, you must power some

or all of them independently. For additional information, please refer to the camera

documentation.

To connect a camera:

1. Install the camera in its desired location.

2. Connect the output of the camera to one of the Video-In connectors on the rear panel of

the unit.

3. If the camera requires an independent power supply, connect its power connector to a

power source. If the MVG 400 can supply enough power for the cameras connected to it,

you can connect the camera to the 12 VDC connector on the rear panel of the unit.

Otherwise, you must use an external power source.

NOTE: A cable with a male RCA connector can be connected to a female BNC connector by using

an RCA-to-BNC adaptor.
