Recommendations on characteristics for choosing the cameras:

  • Minimal resolution is 2 MP.
  • Matrix size not less than 1/2.8".
  • Possibility of shutter speed control (at least, values 1/2 ~ 1/1000 are required). Moving objects have to be clearly visible.
  • The less distortion of the lens and of the picture - the better. The detection quality on distorted areas are worse.
  • The more light sensitive will be the matrix - the better. If it is planned to use the detector at the night time - consider FTC cameras.
  • Varifocal lens, with at least x3 optical zoom.
  • Fisheye cameras are not appropriate.
  • RWDR 120 dB (camera hardware WDR).
  • Onvif-compliance (at least S).

Recommendations on camera settings:

  • Camera bitrate has to be sufficient for required resolution, FPS and motion intensity. The camera picture has to be stable, without noise and glitches.
  • Codec has to be H.264.
  • Disable OSD text on camera if possible.
  • Consider using only RWDR if WDR is required.

Factors other than camera characteristics and settings, affecting the Wear Detector performance:

  • The lighting in the scene of detection. The lighting in the scene has to be sufficient and evenly distributed.
  • The positioning of the camera. The most appropriate vertical angle for the installation is 30 degrees - deviations from might cause the unstable work of the detector.
  • Topview angle will not work.
  • Make a camera set up considering that objects and people might obscure each other - in that case the detector will not work efficiently.
