DESCRIPTION
DVR can be controlled remotely by the keyboard of PC by using RS-232 serial
communication signals.
DVR can be controlled remotely by the keyboard of PC by using RS-232 serial
communication signals.
To connect the wire from ALARM INPUT ( PIN 3 -- 6 ) to GND ( PIN 9 ) connector,
DVR will start recording and the buzzer will be on.
When "MENU -> CAMERA -> ALARM" is set to "Low" : When the alarm input
signal is " Low ", the unit starts to record and buzzer.
When "MENU -> CAMERA -> ALARM" is set to "High" : When the alarm input
signal is " High ", the unit starts to record and buzzer.
But when any alarm is triggered, COM disconnects with NC and connects with
NO.
Attention: The voltage restriction is under AV/DC 30V.
Under the normal operation, COM disconnects with NO. But when any alarm is
triggered, COM connects with NO.
Attention: The voltage restriction is under AV/DC 30V.

DVR can be controlled remotely by the keyboard of PC by using RS-485 serial

DVR can be controlled remotely by the keyboard of PC by using RS-485 serial
communication signals.
Connecting the wire from ALARM RESET (PIN 14) to GND (PIN 9) connector will
disable alarms. An external signal to ALARM RESET (PIN 14) can be used to
reset both ALARM OUTPUT signal and DVR's internal buzzer. When any alarm
has been triggered, the signal becomes "Low", and all alarm activities will be
stopped. Under the normal operation, the signal remains "High".
Under the normal operation, COM disconnects with NO. But when any alarm is
triggered, COM connects with NO.
Attention: The voltage restriction is under AV/DC 30V.
