Click
Viewing Window
to open the viewing region settings page. On this page, you can configure
the
Region of Interest
and the
Output Frame Size
for a video stream. For example, you can crop
only a portion of the image that is of your interest, and thus save the bandwidth needed to transmit
the video stream. As shown below, the area of your interest in a parking lot should be the vehicles.
The blue sky is of little value for the surveillance purpose.
Mode - Resolution and Frame rate
For a 5MP model, the default resolution is 5 Megapixels, and if bandwidth or frame rate per second
is of the concern, you can select a lower resolution while enjoying a higher frame rate (e.g., in
traffic monitoring). The other configurable options is 1080P (16:9) at 60fps.
