Installation

AO 1 TO 4 (Alarm Out)

The DVR can activate external devices such as buzzers or lights. Connect the device to
the AO (Alarm Out) and GND (Ground) connectors. AO is an active low open collector
output which sinks 5mA@12V and 30 mA@5V. See
configuring alarm output.

ARI (Alarm Reset In)

An external signal to the Alarm Reset In (ARI) can be used to reset both the Alarm Out
signal and the DVR internal buzzer. Mechanical or electrical switches can be wired to
the ARI (Alarm Reset In) and GND (Ground) connectors. The threshold voltage is below
0.3V and should be stable at least 0.5 seconds to be detected. Connect the wires to the
ARI (Alarm Reset In) and GND (Ground) connectors.
