In Axxon PSIM, you can enable the output of captions with information about the displayed video stream. The captions are displayed in the Surveillance window on top of a video.

You must enable the display of captions (see Enabling the captions showing) and configure the Captioner object beforehand (see Configuring captions display on a video image).

To enable captions with information about the video stream displayed in the Surveillance window, you must add the ShowDisplayingFps=1 parameter to the registry HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\AxxonSoft\PSIM\Debug (see Axxon PSIM base version and Adding string parameters to the registry).

As a result, captions with the following information are displayed:

ParameterWhat the parameter displays

The first line without the parameter name always displays the frame rate of the camera stream.

It is measured in frames per second (FPS).

If the camera is multithreaded, additional lines below are added

Displaying FPS

The frame rate at which the current stream is actually displayed on the screen.

It is measured in frames per second (FPS)

Stream ID

Stream name

CodecCurrent name of a codec. The name is taken from the stream
Resolution

Resolution of the stream received from the server. It is measured in pixels

FPS

Resulting frame rate of the stream. The frame rate is taken from the stream parameters on the server.

It is measured in frames per second (FPS)

BPS

Current bitrate of the stream, MB/s

GOPNumber of intermediate frames between key frames
RenderDisplay type of the monitor

Each parameter is in a separate line of captions.

Note

If the Debug mode is enabled (see The Settings panel of the Axxon PSIM section), the FPS of the digitized video signal is displayed in the Video surveillance monitor (see Actual frame rate). Thus, the key allows comparing these values.
