Dear Axe,
1. Ensure that all roads within the 50-meter scope around the camera are straight and there are no junctions so that the camera directly faces the head or back of the vehicle for taking snapshots.
2. Ensure that there are no traffic lights within the 200-meter scope around the camera to prevent situations when the camera cannot take snapshots of license plates due to vehicle queuing or driving behind another car.
3. Install the camera in a place where there are fewer lanes.
Some cameras are installed in intersections where there are multiple lanes for scattering vehicles with different driving directions. Move these cameras to a middle place where there are fewer lanes.
4. Ensure that the camera is fixed.
To maintain the stability of surveillance videos, the camera and its pole must be able to prevent inferences from the weather (such as heavy wind) or vibration (caused by vehicles nearby).
Thank you.
