Sensor Input
Connecting the Inputs:
Each alarm input can be controlled/switched by a device such as a motion/IR sensor, door
contact sensor, and similar devices. Each device can either be wired as N/O or N/C
(Normally Open/Normally Closed).
Dry contact sensor direct to DVR:
This example is the simplest form of sensor connection for DVR unit. Sensors dedicated
only for the function for the DVR and example below depicts that Motion Sensors are not
outputting any type of voltage (dry contact).
USB Connection
The USB connection ports are used for both back up and mouse control purposes. Either
port can be used for back up via USB memory stick or for mouse control. A third option
for the two USB ports are for firmware updating procedures. You will only need to use one
port for firmware updates.
Two USB ports are located one front side of the DVR and the other in rear side of the DVR.
These ports may be used for both USB mouse connection and for USB memory stick back
up procedures
Ethernet Port
The RJ-45 port is used to connect the DVR to a network through a DTE (Data Terminal
Equipment) device such as a switch or router with an integrated switch. To connect the
system to a network please use a standard RJ-45 cable (patch/straight through) and make
sure both ends of the cable are securely connected to the proper ports. Consult your local
IT administrator for detailed configuration procedures and setup. The maximum cable
length for Category 5e, RJ-45 cable is 100 meter or 300 feet.
