Video Loss
Video loss is the interruption of a signal from a given camera. This
may be caused by a power loss, someone cutting a cable, or a camera
defect.
At the top, select the camera (channel number) and check Enable
Video Loss Detection to allow your system to detect a loss of signal
from the selected camera, as well as to set up the schedule.
The main section of the window is divided into two tabs: Arming
Schedule, and Linkage Method.
Be sure to click Save before leaving this screen.
Arming Schedule
You set up this option for each camera independently. Generally
speaking, there is no reason not to have video loss detection on.
The main portion of the window shows the schedule for the selected
camera. Each box covers one hour of time (with a dotted line at the
half-hour mark), and is color-coded to show the camera’s scheduled
activity. Blue indicates video loss is active; white means the camera
is not enabled during that time.
To adjust the schedule, press Edit at the top right (this button is only
active if you have enabled video loss detection in the checkbox at
the top). If you need help, see “Arming Schedule Tool” on page 95.
Linkage Method
This tab helps you set up the camera to take action when an
event occurs, like activating a siren, locking a door, or alerting key
personnel. Despite its appearance, this is not a table; it’s just an
arrangement of columns.
For help on linkages, see “Linkage Control” on page 98. Unlike
other Linkage Method tabs, this one does not have the Trigger
Channel column. This is because if communication to the camera
has been lost, the recorder cannot tell it to trigger an alarm.
However, your recorder could send an alert, trigger other alarms, etc.
