If you are using PT090 and you upgrade to Symphony 6.12 and later versions, the PT090 analytic engine will not be visible as an option in the analytic engines list. Symphony 6.12 will continue to run the PT090 analytic engine correctly but it can no longer be applied to new cameras and existing configuration cannot be edited.
We strongly recommend that you enable the PT091 analytic engine on your cameras. PT090 can be disabled by simply enabling PT091 and auto-tracking rules will not need to be reconfigured.
Note: If you previously did not use default settings when configuring the PT090 analytic engine, then you will need to reconfigure them when enabling PT091. |
The PT091 analytic engine is used to automatically control PTZ cameras when activity is detected. After the PT091 is enabled for a PTZ camera, a Rule can be configured where the PTZ camera can be automatically controlled by Symphony to zoom and follow objects that have broken the Rule (such as entered into the alarm zone or crossed a tripwire).
• Minimize the number of moving objects in the camera’s field of view that you do not want to track, for example, trees.
• Eliminate On Screen Display (OSD) of PTZ movements. Some cameras display information on the screen when panning/tilting/zooming. For example, “Zooming 5x” may appear in large letters at bottom of screen. The Symphony video engines may erroneously try to track this text instead of the objects of interest. Camera manufacturers typically provide a way to turn off this text. For example:
• In a Bosch camera, you might select the Camera OSD off option in one of the Settings Groups of the camera Web page interface.
• In a Pelco camera, you might have to click the OSD button, then select Display Setup and turn OFF various labels in the camera Web page interface.
• The camera must be stable, if wind or vibrations causes the camera to move, false alarms will occur.
• This engine does not perform well indoors, or where the objects are very close to the camera, or if the environment is very busy.
• Absolute positioning cameras are preferred over relative positioning cameras.
• MJPEG mode, or running MPEG-4 at higher frame rates increases performance.
• Ensure that enough available CPU is present to perform proper analysis.
• When troubleshooting, increase the frame rate and image quality settings. Do NOT maximize analysis resolution. In general, do not go above 400 x 300. The higher the analysis resolution, the more strain on CPU. For analysis FPS, stay at 12 FPS or below.
