the paneling, of a car. Ensure the unit has at least 20 centimeters (eight inches) of space above it and on all sides for

ventilation.

When choosing a location for the CVG-M, bear in mind that the unit must be connected to a power source and a

LAN or a PC, and that other devices (cameras, sensor, etc.) must be connected both to it and to power sources. If

the unit will be installed in a vehicle, it must be connected to the vehicle battery and ignition (if required), and the

cellular and GPS antennas must be located relatively high up and in exposed locations (see Connecting the Cellular

Antenna, page 26; Connecting the GPS Antenna, page 28) Choose a location in which these connections are

feasible.

Preventing Overheating

CVG-M units should be installed in the passenger compartment in a location that is cooled by the vehicle's air-

conditioning when the air conditioner is on. Ideally, the units should be installed in insulated plastic containers with

built-in fans. Each container should have two fans, one to draw cool air into the container and the other to push hot

air out of it. Containers of this type are available for purchase from vehicle-accessory suppliers. The containers

should be installed in the vehicles in accessible locations, with as much ventilation as possible. The ends of cellular

and GPS antennas should be placed outside the containers. If you plan to remove the micro-SD card from the unit

without removing the unit from the container, make sure to allow enough space at the front of the unit to do so (see

Appendix 1: Removing the MicroSD Card, page 34).

NOTE: Do not install the unit in a metal container; metal interferes with wireless reception.
