Sending Alarms

•When motion is detected, the Alarm Replay command is issued via the serial command (VISCA) communication line.

Basic Functions

•When multiple motions are detected or motion is detected in another frame within the set interval following the original time the alarm was issued, another alarm command is not issued.

•When motion is detected after the interval time elapsed, the alarm is issued again.

Setting Commands

•MD On/Off

The Display mode is selected by the Function Set command and frames are set by the Frame Set command. By sending an MD On command, the frame is displayed when motion is detected in the set frame. The Alarm Reply command is set via the serial command (VISCA) communication line.

•Function Set

The Display mode function has two modes. One is the Frame Mode, in which the detected frame is displayed on the screen, and the other is the Block Mode in which the block where the motion is detected is displayed from among the set of 12 (horizontally) ⋅ 8 (vertically) blocks. The Frame Mode is normally used. For examination and verification when the camera is installed, display blocks using the Block Mode. In the Block Mode, the Alarm Reply command is not sent.

(When pq and rs are 0, the command is received, but the setting is disabled.)

•Frame Set

You can set up to four frames by assigning the starting and terminating points.

Note

Set a terminating point higher vertically and horizontally than the starting point. If you set the wrong value, the command yields an error.
