Step 8. Set the motion sensitivity of image when “video freeze” alarm will be triggered. Adjust the
sensitivity according to the signal being monitored, on a range of 1 (for filtering out noise in a
noisy signal) to 128 (for a clean signal). Also, the lower the “sensitivity” level set, a “not so
noticeable difference” in frame by frame content comparison (e.g., a talk show video where the
background is constant and the only motion detectable is the announcer’s lip movement) may
trigger the alarm. In this case consider increasing the “sensitivity level” or “set duration” (next
item) values.
Step 9. Set the “video freeze” alarm response time (second).
Video Black and Video Freeze cannot happen simultaneously. When both conditions exist, Video Black
has the higher priority.
Likewise, both functions are not available for analog input signal.
