Network Port
The DVR can be networked using the 10/100Mb Ethernet connector. Connect a Cat5 cable with an RJ-45
jack to the DVR connector. The DVR can be networked with a computer for remote monitoring, searching,
configuration and software upgrades. See the
Network Setup
section in this chapter for configuring the
Ethernet connections.
CAUTION: The network connector is not designed to be connected directly with cable or wire
intended for outdoor use.
Connecting Alarms
NOTE: To make connections on the Alarm Connector Strip, press and hold the button
and insert the wire in the hole below the button. After releasing the button, tug gently
on the wire to make certain it is connected. To disconnect a wire, press and hold
the button above the wire and pull out the wire.
Alarm In 1 to 16:
You can use external devices to signal the DVR to react to events. Mechanical or electrical switches
can be wired to the
ALARM IN
and
GND
(Ground) connectors. The threshold voltage for NC (Normally Closed) is
above 4.3V
and for NO (Normally Open) is below 0.3V, and it should be stable at least 0.5 seconds to be detected.
GND (Ground):
Connect the ground side of the alarm input and/or alarm output to a
GND
connector.
NOTE: All the connectors marked GND are common.
NO (Relay Alarm Output):
Connect the device to the
