What capture mode to choose depends on the requirements for the frame rate and resolution of the specific surveillance setup. For
specifications about available capture modes, see the product's datasheet at axis.com.
Remote focus and zoom
The remote focus and zoom functionality allows you to make focus and zoom adjustments to your camera from a computer. It is a
convenient way to ensure that the scene's focus, viewing angle and resolution are optimized without having to visit the camera's
installation location.
Privacy masks
A privacy mask is a user-defined area that covers a part of the monitored area. In the video stream, privacy masks appear either as
blocks of solid color or with a mosaic pattern.
You'll see the privacy mask on all snapshots, recorded video, and live streams.
You can use the VAPIX® application programming interface (API) to hide the privacy masks.
Important
If you use multiple privacy masks it may affect the product's performance.
You can create several privacy masks. The maximum number of masks depends on the complexity of all the masks combined. The
more anchor points in each mask, the fewer masks you can create. Each mask can have 3 to 10 anchor points.
Important
Set the zoom and focus before you create a privacy mask.
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.
The video streaming indicator is another type of overlay. It shows you that the live view video stream is live.
Streaming and storage
Video compression formats
Decide which compression method to use based on your viewing requirements, and on the properties of your network. The
available options are:
Motion JPEG
Note
To ensure support for the Opus audio codec, the Motion JPEG stream is always sent over RTP.
Motion JPEG, or MJPEG, is a digital video sequence that is made up of a series of individual JPEG images. These images are then
displayed and updated at a rate sufficient to create a stream that shows constantly updated motion. For the viewer to perceive motion
video the rate must be at least 16 image frames per second. Full motion video is perceived at 30 (NTSC) or 25 (PAL) frames per second.
The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image quality and access to every image
contained in the stream.
H.264 or MPEG-4 Part 10/AVC
