9.3.7 VIDEO LOSS
Video Loss Setup allows the administrator to define how the system responds when video signal is lost
for the camera.
The following is a brief description for each item in this menu and its specific operations:
•
CAMERA
Select the camera to define video loss triggered events.
• DURATION
Set the length of time the buzzer and the corresponding Alarm Out relay will remain triggered once
video loss is detected for this camera. The Buzzer and Alarm Out relay will reset immediately once
video signal is restored.
• CAMERA TO GO
The Camera to Go setting will specify which PTZ camera will go to a predefined preset when video loss is
detected for this camera. This feature is used in a system that includes PTZ cameras since the Camera
to Go must be a PTZ camera.
• GOTO PRESET
This feature works in conjunction with the Camera to Go setting above and defines the preset position
the “Camera to Go” PTZ camera will go to when video signal is lost for this camera. For more details
about preset positions for PTZ cameras, refer to Section 7.
• PRE-RECORD
Define how much time the DVR will record before video loss is detected. The Pre Record FPS set in
Section 9.3.5 determines the frame rate of this recording.
Note: Actual pre-record time may be shorter than the value set if the total size of the pre-record video
exceeds the pre-record video buffer.
• ALARM OUT
Define which Alarm Output will be triggered when video loss for this camera is detected. Select N/A
for none or either of the Alarm Outputs (1 for NC or 2 for NO).
• BUZZER
By default, the internal buzzer is enabled to sound when video loss for the camera is detected.
