Motion Detection
The ZAVIO network camera is able to monitor the video footage for movements and trigger
an alert if motion has been detected. This motion detection does not utilize passive infrared,
but instead it relies on a frame by frame comparison of the video footage the camera captures.
You can define more than one motion detection area. The example above shows that
so-called hotspot has been created for the area of the window. When you set up an event for
motion detection, you can select which motion detection area you wish to monitor.
Threshold and sensitivity will need to be set up so that you don’t miss important events and
are not flooded by false alarms either. Finding the right values will require some trial and error.
There are no standard values that simply “will work” as it depends very much on the actual
location and light levels. Generally speaking, increasing the sensitivity while lowering the
threshold will generate more false alarms but it ensures that you will not miss an important
event. Doing the opposite will of course have the opposite effect: Fewer false alarms at an
increased risk or missing an important event.
