Additional Equipment
One or two video cameras should be connected to the CVG-M. You must acquire the cameras you require; they are
not included in the CVG-M package. For information about camera compatibility and about connecting the cameras
to the unit, see Connecting Cameras, page 13, or consult your vendor.
In addition to the cameras, you may wish to connect some or all of the optional equipment listed below to the CVG-
M unit. For additional information about these items and the cables required to connect them, please refer to the
installation instructions for each type of device.
NOTE: This equipment is not included in the CVG-M package.
• SIM card for the cellular network
• Dry-contact sensor, toggle (on-off) switch to change the active outline (see Connecting Sensors, page 15), or
push-button switch to change the display in a connected CCTV monitor (see Connecting a Switch, page 24)
Note: A dry-contact sensor or switch can be connected directly to the Sensor connector on the CVG-M unit.
If you use either an ADAM module or an IA relay board, as described below, you can connect an additional
16 dry-contact sensors via the unit’s RS232/485 connector.
Note: If you connect a touchscreen monitor to the CVG-M, you cannot also connect an ADAM module or an
IA relay board.
• ADAM Data Acquisition Module and ADAM isolated RS232->RS422/RS485 converter, for connecting up to
16 dry-contact sensors (see Connecting Sensors, page 15)
• Intelligent Appliance IA-3126-2 relay board, for connecting up to 16 dry-contact sensors (see Connecting
Sensors and Activators Using an IA Relay Board, page 20) and 16 activators to the CVG-M unit
• Dry-contact activator (an alarm or other device that is turned on or off in response to the activation of a sensor;
see Connecting an Activator, page 19)
Note: An activator can be connected directly to the CVG-M unit. If you use an IA relay board, as described
above, you can connect an additional 16 activators via the unit’s RS232/485 connector.
Note: If you connect a touchscreen monitor to the CVG-M, you cannot also connect an IA relay board. In this
case, you can only connect one activator to the unit.
• Microphone (see Connecting a Microphone, page 21)
• Speaker or headphones (the unit already contains a built-in speaker; for additional information, please refer to
the TVG System Guide)
• CCTV monitor for closed-circuit video display (see Connecting a CCTV Monitor, page 22)
• For units that will be installed in a truck or bus, an insulated container with a built-in fan in which the CVG-M
unit can be placed (see Preventing Overheating, page 8)
• Additional micro SD cards (see Appendix: Removing the Micro SD Card, page 32)
