How and where you set up your cameras affects video analytics performance. An optimal camera setup can minimize missed or false detections.
Position the camera to meet the following conditions:
- People can be seen traveling along the longest side of the image.
- The camera has a top-down view (90° from ceiling).NOTE: Do not use fish-eye cameras or cameras with high distortion. The horizontal field of view should not exceed 120°.
Adjust the camera to meet the following conditions:
- There is no motion blur in the video. Faster shutter speeds produce less motion
- The image is high-contrast, but not under-exposed or over-exposed.
- The frame rate is 12 fps.
- The resolution is 720p.
Ensure the following:
- People do not linger where the counting line is, such as security guards at store entrances or groups of people waiting in queues.
- Each entrance is monitored by one camera. If more than one camera is required to monitor a large entrance, delimit the cameras' view of the entrance with furniture.
- The area you want to monitor is well lit.
- The background is uniform.Example: Highly patterned floors might decrease the accuracy of detections.
- People crossing the line can be fully seen in the video.Example: The heads of the people crossing the line must be in frame.
- The entrance that you want to monitor is centered in the image. The counting line
configured in the analytics scenario should be drawn where the entrance is.
