The requirements for cameras when you work with the Sweethearting at checkout detection module are given in the following table.

Camera

  • Resolution must be at least 1920x1080 pixels.
  • FPS is at least 12.
  • Color: only color cameras

Scene and camera angle

  • The angle of the surveillance camera must be set so that the cashier's hands are clearly visible. The control area (where the cashier holds hands with the goods in front of the reader) must be from 150x150 to 250x250 pixels
Object images
  • The area of interest of the detector (see Configuring the Sweethearting at checkout detection module) must be set in a way that the initial position of the goods is outside this area. The goods must be carried along the entire specified area (in case of vertical or horizontal location of the area—from one side to the other, and if the area is angled—from one diagonal to another)
Lighting
  • Objects must be visually separable from the background and from each other

We don't guarantee the correct operation of the detector if you use the video stream or frames that were masked before they got into Axxon PSIM by the IP camera or similar means and methods.
