Requirements
Positioning of cameras
Like any AI-based system, the accuracy of algorithm decisions is dependent on the context, like positioning of the cameras. The better the positioning, the more the system is capable of recognizing the shoplifting gestures and thus, the higher the detection rate. Below you can find recommendations for the optimal positioning of the cameras:
Cameras should be centered on the aisle:
...
Detection range: 1.5 to 12m
...
The closer a shoplifter is to the camera, the higher detection rate (e.g. within 1.5m the detection rate is 70%, in the range of 12m - about 30%).
Optimal height: 1.8 to 3.5m
...
The height of the cameras influence the visibility of what is going on in the store and the detection performance.
What to avoid
Below you can find practices that we recommend to avoid, as long as they can lower the detection rate considerably:
Too wide field of view: when the camera’s field of view is too wide, there can be too many people present simultaneously, which reduces the detection rate because gestures may be hidden by other people or located far away from the camera (>12m).
...
Dead angles: customers cannot be seen between two shelves when cameras focus on blocks of shelves from the side. Avoid placing cameras placed laterally on shelves arranged in blocks and make sure cameras focus on the aisles.
