Video Blind
Figure 20: Event – Video Blind setup screen.
The DVR checks to see if anything is blinding a camera.
Highlighting the box under the Sensitivity heading allows you to adjust the DVR's sensitivity to video blind for Black
and White independently from 0 (Never) and 1 (least sensitive) to 15 (most sensitive).
NOTE: Video blind might NOT be detected for a camera with a very noisy image especially when set for low
sensitivity values.
Highlighting the box under the Activation Time heading allows you to set the duration before the DVR will report a
Video Blind. The DVR will not consider any blinded camera to be a Video Blind if the detected blindness is less than
the Activation Time set on this screen.
Highlight the box under the Actions and press the
button. The DVR can be set to react to video blind differently
for each camera. Each camera can be associated with another camera, trigger an Alarm-Out connector, sound the DVR's
internal buzzer, notify a number of different devices, and/or move PTZ cameras to preset positions.
Highlight Use Ignoring Time and press the
button to toggle between On and Off. When set to On, the DVR will
ignore video blind events occurred during the preset period. Highlighting Time Setup and press the
button allows
you to set up event ignoring time.
