Alarm Function

This function instructs the camera to detect movement

within the monitoring area and then send an alarm

signal automatically.

A High level signal is output when camera detects

movement inside the monitoring area. A Low level

signal is output when object stops moving.

However, when the mode is set to “DAY/NIGHT”, the

High level signal is output for dark and the Low level

signal is output for bright.

The Detect signal goes out through the serial command

(VISCA) communication line.

Example

1. A door is motionless, so the Detect Level is Low.

2. At the moment when the door is opened by

someone, the Detect Level goes to High.

3. The Detect Level is High while the shooting object

is moving.

4. When the door is closed, Detect Level goes to Low

again, or signals are output only once at the time of

switching between High Level and Low Level.
