Important
If you use multiple privacy masks it may affect the product’s performance.
Overlays
Overlays are superimposed over the video stream. They are used to provide extra information during recordings, such as a timestamp,
or during product installation and configuration. You can add either text or an image.
Guard tours
A guard tour displays the video stream from different preset positions either in a predetermined or random order, and for configurable
periods of time. Once started, a guard tour continues to run until stopped, even when there are no clients (web browsers) viewing the
images.
Streaming and storage
Bitrate control
With bitrate control, you can manage the bandwidth consumption of your video stream.
Variable bitrate (VBR)
With variable bitrate, the bandwidth consumption varies based on the level of activity in the scene. The more activity in the scene,
the more bandwidth you need. You are guaranteed constant image quality but it requires storage margins.
Maximum bitrate (MBR)
With maximum bitrate, you can set a target bitrate to handle bitrate limitations in your system. You may see a decline in image
quality or frame rate when the instantaneous bitrate is kept below the specified target bitrate. You can choose to either prioritize
image quality or frame rate. We recommend that you configure the target bitrate to a higher value than the expected bitrate. This
gives you a margin for additional complexity that needs to be captured.
