CAUTION: When using the Factory Reset, you will lose any setting you have made.
If you want to use the same DVR name registered on the DVRNS server after
initializing the system using the factory reset, you need to contact the DVRNS
server manager. Please record and save the help desk information before factory
reset.
To reset the unit, you will need a straightened paperclip:
1.
Turn the DVR off.
2.
Turn it on again.
3.
While the DVR is initializing, poke the straightened paperclip in the unlabeled hole to the
right of the RS-232C connector.
4.
Hold the switch until all the LEDs on the Front Panel are lit.
NOTE: When the DVR successfully resets to factory defaults all the LEDs on the Front Panel
flash three times.
5.
Release the reset switch. All of the DVR's settings are now at the original settings it had
when it left the factory.
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.
AI 1 to 4 (Alarm In)
You can use external devices to signal the DVR to react to events. Mechanical or electrical
switches can be wired to the AI (Alarm In) and GND (Ground) connectors. The threshold voltage
for NC (Normally Closed) is above 4.3V and should be stable at least 0.5 seconds to be detected.
For NO (Normally Open), the threshold voltage is below 0.3V. See Chapter 3 — Configuration for
configuring alarm input.
GND (Ground)
Connect the ground side of the Alarm input to the GND connector.
