CAMERA CABLES 

Camera Cables (available in lengths of 15, 35 or 50 feet) use the STP (shielded twisted pair) cable standard. The 
Camera Cables are connected using molded 2x3 Molex interfaces that are keyed to prevent improper mating. Each 
connector uses a clip to snap securely to each camera and to the inputs on your DVR. Typical configurations are 
such that the passenger cameras connect to inputs 1 and 2; and, if available, door, exterior, or driver cameras 
connect to inputs 3 and 4. After the installation, all Camera Cables should be concealed and holes filled with 
grommets to protect the equipment from vandalism. 
 

EVENT MARKER

 

The Event Marker is used for the driver to indicate a critical event during recording, which the DVR will interpret as a 
priority video for later review. When the driver presses the event marker button, the DVR will mark all video feeds 
from 150 seconds prior to and after the button press. These priority event videos can be retrieved by the technician, 
using our USB memory stick, to be viewed on a computer with the DVRViewer application installed.

 

The Event Marker module has one button, to signal an event, and 3 color lights to indicate three DVR states: green 
for POWER; amber for hard drive RECORDING; and red for VIDEO LOST when a camera signal has been lost. 

 

POWER CABLE

 

A three-wire, 12-feet-long Power Cable is used for connecting the DVR directly to the battery power in the vehicle’s 
electrical box. The cable uses a large molded 2x2 Molex connector that is keyed, thereby connecting to the DVR in 
only one orientation. The cable’s three wires are described in the following table: 

 

POWER CABLE  

BUS ELECTRICAL PANEL 

DC IN (Red) 

Constant LIVE Power Source (battery side of solenoid, direct current) 

GND (Black) 

Ground in bus electrical panel 

IGN. ON/OFF (White) 

Ignition-switched Power (live only if ignition is turned to ON/ ACC) 

 

Two screws (#4 thread, 3/8― long) are included to securely fasten the Power Cable to the DVR. Securing the Power 
Cable to the DVR prevents occupants from deactivating the system by disconnecting the Power Cable. NOTE: MAKE 
SURE TO FUSE BOTH THE RED AND WHITE POWER LINES WITH A 7.5A FUSE (NOT INCLUDED) 

 

SENSOR & ALARM CABLE (DIGITAL I/O) 

The Digital I/O Cable is used for connecting the DVR to the vehicle’s pertinent electrical functions, such as the turn 
signals, brake pedal, and the stop-arm. The cable is 15 feet long and connects to the DVR using a molded 2x5 
Molex connector, and to the vehicle’s equipment using 4 twisted pairs of wires. Using the Digital I/O Cable is an 
optional function at your discretion.
