- Resolution must be at least 640x360 pixels.
- Tracker-based analytics works with both colorless (gray) and color images. We recommend using color cameras. When you use black-and-white cameras, the recognition quality can be noticeably worse.
The camera angle should be as horizontal as possible.
Recommended camera tilt angle is from 0 (parallel to the ground) to 60 degrees.
- The camera position for human detection should be as shown in the image below:
Incorrect camera position:
- Lighting in the scene is at least 50 lux. In conditions of insufficient or excessive lighting (night or light-striking), stable operation of the analytics isn't guaranteed
- No abrupt changes in lighting
- Moving objects are visually separable from each other
- The background is mostly static and doesn't change abruptly
- Moving objects are minimally obscured by static objects in the scene (columns, trees, and so on)
- The analyzed scene doesn't have reflective surfaces and sharp shadows from moving objects. If present, they must be masked
- Camera shake doesn't result in image offsets greater than 1% of the frame size
