In the Axxon PSIM, you can correct (dewarp) video from fisheye cameras in the Video Surveillance Monitor as well as in all camera windows opened through other interfaces, for instance,

• through the Event Log (refer to Event control via Event Viewer),

• during search by captions (refer to Search in the captions database), etc.

Conversion of video from fisheye cameras when displaying it on the video surveillance monitor is possible in Axxon PSIM. The conversion type is selected when adding a camera to the Monitor (see Selecting and configuring video cameras). To use this feature specify the lens type and fish eye camera location when configuring it in Axxon PSIM:

  1. Go to the Additional settings tab on the settings panel of the Camera object corresponding to the fisheye camera (1).

  2. Select the Standard fisheye lens value in the Lens type dropdown list if this is a fish eye camera (2). If a camera with anamorphic lens is in use, then select its type in this dropdown list.
    With some settings there can be some artifacts at the top of video for a standard fisheye lens. If there are such artifacts , then select the Autocalibration in this dropdown list.

    Important!

    Video will be calibrated every time the settings are applied.
  3. In the Camera location dropdown list select the value corresponding to the camera (3).
  4. Frame edge areas can degrade or loss information as a result of dewarping. By default, such degraded edges are cut off, i.e. not displayed on the Video Surveillance Monitor. Default visible frame part is 75% for the Ceiling position and 66% for the Wall position. To increase or decrease the displayed frame area, change the value of the Visible part (4) parameter correspondingly. The value of this parameter is chosen experimentally, depending on the camera.
  5. Click the Apply button (5).

The fisheye camera is now configured.
