PTZ (Pan Tilt Zoom)
How to limit pan, tilt, and zoom movements
In this example, the camera is surveilling a parking lot with nearby apartment buildings. Set pan, tilt, and zoom limits
to ensure privacy for residents. To limit pan, tilt, and zoom movements, go to Settings > PTZ > Limits.
Streaming and storage
How to choose the 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 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 a 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.
How to set up network storage
To store recordings on the network, you need to set up network storage:
1. Go to Settings > System > Storage.
2. Click Setup under Network storage.
3. Enter the IP address of the host server.
4. Enter the name of the shared location on the host server.
5. Move the switch if the share requires a login, and enter the username and password.
6. Click Connect.
How to add audio to your recording
Edit the stream profile which is used for the recording:
1. Go to Settings > System > Stream profiles.
2. Select the stream profile and click Modify.
3. In the Audio tab, select the Audio stream checkbox and select On from the drop-down list.
4. Click Ok.
