4.7.6 Video Loss Alarm
The DVR supports a Video Loss Alarm function which allows an Alarm Event to occur when a camera loses signal. The
lost signal can be due to Power failure to the camera, the camera cable being cut or unplugged, or the camera being
damaged in some way.
In order to use Video Signal Loss detection, cameras must either be turned ‘ON’ or ‘OFF’. This is because the DVR
needs to know which cameras it should expect to receive signals from. To turn camera(s) ‘ON’, open FRAME SETUP,
and set the Frames Per Second to anything above zero. By designating zero frames per second you are essentially
saying that the camera is not going to be used by the DVR.
Video Port – Refers to the output channel. The
Ports use RCA jacks.
Cameras – The camera buttons allow selection
of cameras to sequence on the selected Port.
Motion/Sensor Event – This option allows
immediate output of a Motion or Sensor Event
on the selected Port.
Event Holding Time – The Event Holding Time
specifies the duration for which the Motion or
Sensor Event will be displayed.
Auto Switching Time – The Auto Switching
Time specifies the duration which the selected
cameras will sequence one to the next.
USE – Enables the selected Port.
4.7.7 Auto Sequencing
The DVR supports an Auto Sequencing setting which allows the video output device to cycle through user specified
camera channels.
NOTE: In order to use the Auto Sequencing feature, an output device must be connected to the DVR unit.
