This camera is designed to deliver up to four different streams. If a fifth unique stream is requested, the camera canʼt
provide it, and an error message is displayed. The error message depends on the way the stream is requested. The
streams are used on a first come, first served basis. Examples of instances that use a stream are:
• Live viewing in a web browser or other application
• While recording - continuous or motion triggered recording
• An event that uses images on the camera, for example an event that sends an e-mail with an image
every hour
• An installed and running application, such as AXIS Video Motion Detection, will always consume a video
stream, whether it is used or not. A stopped application does not consume a video stream.
The camera can deliver more than four simultaneous streams provided the configuration of any additional stream
is identical to any of the first four streams. Identical configuration implies exactly the same resolution, frame rate,
compression, video format, rotation etc. For more information see the white paper "Max number of unique video
stream configurations", available at

Performance considerations

When setting up your system, it is important to consider how various settings and situations affect the performance.
Some factors affect the amount of bandwidth (the bitrate) required, others can affect the frame rate, and some affect
both. If the load on the CPU reaches its maximum, this also affects the frame rate.
The following factors are the most important to consider:
• High image resolution or lower compression levels result in images containing more data which in turn
affects the bandwidth.
• Rotating the image in the GUI will increase the product's CPU load.
• Access by large numbers of Motion JPEG or unicast H.264 clients affects the bandwidth.
• Access by large numbers of Motion JPEG or unicast H.265 clients affects the bandwidth.
• Simultaneous viewing of different streams (resolution, compression) by different clients affects both frame
rate and bandwidth.
Use identical streams wherever possible to maintain a high frame rate. Stream profiles can be used to
ensure that streams are identical.
• Accessing Motion JPEG and H.264 video streams simultaneously affects both frame rate and bandwidth.
• See .
• Reduce the number of applications running on the client computer.
• Limit the number of simultaneous viewers.
• Check with the network administrator that there is enough bandwidth
available.
• Lower the image resolution.
• Log in to the deviceʼs webpage and set a capture mode that prioritizes
frame rate. If you change the capture mode to prioritize frame rate it might
lower the maximum resolution, depending on the device used and capture
modes available.
• The maximum frames per second is dependent on the utility frequency
(60/50 Hz) of the Axis device.
Web browsers donʼt support H.265 decoding. Use a video management system or
application that supports H.265 decoding.
