Privacy Masks; Overlays - Axis M3104-LVE User Manual

AXIS M31 Series
Setup
When you set up a view area, we recommend you to set the video stream resolution to the same size as or smaller than the view area
size. If you set the video stream resolution larger than the view area size it implies digitally scaled up video after sensor capture,
which requires more bandwidth without adding image information.

Privacy masks

A privacy mask is a user-defined area that prevents users from viewing a part of the monitored area. In the video stream, privacy
masks appear as blocks of solid color.
You'll see the privacy mask on all snapshots, recorded video, and live streams.
You can use the VAPIX® application programming interface (API) to turn off the privacy masks.
Important
If you use multiple privacy masks it may affect the product's performance.
Hide parts of the image with privacy masks
Create a privacy mask to hide a part of the image:

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.
