AI 1 to 8 (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 voltage range is from 0V to 50V. When the
electrical switch is wired, the threshold voltage for NC (Normally Closed) is below 2.4V and for NO (Normally Open)
is above 2.8V, and it should be stable at least 0.5 seconds to be detected. See
Chapter 3 ─ Configuration for configuring
alarm input.
G (Ground)
: Connect the ground side of the Alarm input and/or alarm output to the G connector.
NOTE: All the connectors marked G are common.
Two RS232 ports are provided to connect external devices such as the GPS.
The DVR can be controlled remotely by an external device or control system using RS485 half-duplex
serial communications signals. The RS485 connector can also be used to control PTZ (pan, tilt, zoom)
cameras. See
Chapter 3 ─ Configuration and the PTZ camera or remote controller manufacture’s manual
for configuring the RS485 connection.
The DVR can activate external LED devices. Heartbeat (
H
) and recording status (
R
) outputs are provided
(50mA@12VDC). A heartbeat LED will blink at a constant rate as long as the DVR is operating since
the system boots. When the system stops operating, the LED blinks for one minute and stops blinking.
A recording status LED will blink when the DVR is recording or searching video on the hard disk drive.
