Frame Rate and Performance

The Nextiva S5500 PTZ series support H.264 and MJPEG. Video decoding is

supported at up to D1 at 30fps on four independent streams (3 × H.264 and 1 ×

MJPEG). In general, the performance for displaying video on monitors varies

depending on the tile layout, screen resolution, compression mode, and bitrate.

The following settings can be supported simultaneously on the two encoders

when streaming in H264 format. The Nextiva S5500 PTZ series can also stream

in MJPEG. Do not assume any improvements if those codec are used since the

Nextiva S5500 PTZ series are optimized to stream H264 as well as MJPEG.
