AXIS 215 PTZ/AXIS 215 PTZ-E - Technical Specifications

Important!

•The figures displayed here are the values as delivered by the camera. If other restrictions are currently in force, (e.g. band- width limitation) these values might not correspond to those actually received by the client.

•For Motion JPEG, these values will only be accurate as long as no frame rate limit has been specified.

Frame rates - Motion JPEG

The following test results show the frame rates in frames/second (fps) for Motion JPEG streams from the AXIS 215 PTZ/AXIS 215 PTZ-E, using a compression level of 50%. Note that these values are guidelines only - actual values may vary.

Resolutions	60Hz/50Hz
4CIF	30/25 fps
2CIF expanded	30/25 fps
2CIF	30/25 fps
CIF	30/25 fps
QCIF	30/25 fps

Frame rates - MPEG-4

The following test results show the frame rates in frames/second (fps) for MPEG-4 streams from the AXIS 215 PTZ/AXIS 215 PTZ-E. Note that these values are guidelines only - actual values may vary.

The MPEG-4 test conditions:

• Compression level = 50%

• Video Object Type = Advanced Simple

• GOV structure = IP*

Resolutions	60Hz/50Hz
4CIF	25/21 fps
2CIF expanded	25/21 fps
2CIF	30/25 fps
CIF	30/25 fps
QCIF	30/25 fps

*Note that setting the GOV structure to use “I-frames only” will increase the frame rate.

Bandwidth

As there are many factors affecting bandwidth, it is very difficult to predict the required amounts. The settings that affect bandwidth are:

•the image resolution

•the image compression

•the frame rate

•the MPEG-4 object type

•the MPEG-4 GOV structure

•the audio settings (AXIS 215 PTZ only)

There are also factors in the monitored scene that will affect the bandwidth. These are:

•the amount of motion

•the image’s complexity

•the lighting conditions.
