About autotracking
Autotracking detects movement in the camera's field of view, for example a moving vehicle or person, and follows the moving object
until it stops or disappears from the monitored area. In case there is much simultaneous movement, the product selects the area with
the most amount of motion. When there are no moving objects in the field of view, the camera returns to the home position.
Important
• The autotracking feature is designed for areas where there is a limited amount of movement.
• If both autotracking and guard tour are enabled, we recommend using the PTZ control queue. In the control queue,
guard tour has lower priority than autotracking, preventing the product from stopping autotracking to maintain or start
a guard tour.
• Autotracking does not follow object behind privacy masks or objects in exclude areas. You can also set up maximum limits
so that the autotracking only triggers within a certain range in the live view.
Streaming and storage
How to choose video compression format
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. Installing additional unlicensed
copies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.
H.264 can, without compromising image quality, reduce the size of a digital video file by more than 80% compared to the Motion
JPEG format and by as much as 50% compared to the MPEG-4 standard. This means that less network bandwidth and storage space
are required for a video file. Or seen another way, higher video quality can be achieved for a given bitrate.
How to reduce bandwidth and storage
Important
If you reduce the bandwidth it can result in loss of details in the picture.
1. Go to live view and select
H.264
.
2. Go to
Settings > Stream
.
3. Do one or more of the following:
-
Turn on the Zipstream functionality and select the desired level.
-
Turn on dynamic GOP and set a high GOP length value.
-
Increase the compression.
-
Turn on dynamic FPS.
