Color palettes

Color palettes applied to thermal images help the human eye distinguish image details. The colors in the palette are artificially
created pseudocolors that emphasize temperature differences.
The product has several color palettes to choose from. If an operator watches the video stream, you can choose any of the palettes. If
the video stream is only used by applications, select the white-hot palette.

Privacy masks

Note
Privacy masks are only available for the visual channel.
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.

Pan, tilt, and zoom (PTZ)

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

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
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
Note
H.264 is a licensed technology. The Axis product includes one H.264 viewing client license. To install additional unlicensed
copies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.
