Sending and processing data

The intervention threshold of cameras for speed limit enforcement is the speed starting from which a picture is taken of the vehicle and a cautionary fine is sent to the driver. The intervention threshold includes both the expanded measurement uncertainty of the camera and the agreed permissible error allowed for the driver.

Violations will be processed starting from speeds:

  • 50 km/h area: 53 km/h (camera configuration with expanded measurement uncertainty 57 km/h)
  • 70 km/h area: 73 km/h (camera configuration with expanded measurement uncertainty 77 km/h)
  • 90 km/h area: 93 km/h (camera configuration with expanded measurement uncertainty 97 km/h)
  • 100 km/h area: 103 km/h (camera configuration with expanded measurement uncertainty 108 km/h)
  • 110 km/h area: 113 km/h (camera configuration with expanded measurement uncertainty 118 km/h)

Cameras for speed limit enforcement create an encrypted recording of the speeding incident, which contains relevant data and a photo of the vehicle under question. Encrypted recordings are sent to the data centre of the Estonian Road Administration using secure data channels. There the automatic recording is decrypted and authenticated, the measurement results presented with expanded measurement uncertainty and the licence plate automatically identified.

Following that, the specially processed case data are sent to the Police and Border Guard Board through the data exchange layer (X-Road) of the national data system to be processed. Original recordings are kept in the information system for cameras for speed limit enforcement (in the data centre of the Estonian Road Administration).


How do the police process exceeding the speed limit?

Exceeding the permitted speed limit is not always the reason for seeing a flash of light from the camera. It could also mean that the camera for speed limit enforcement is momentarily turning off prior to sending data. This takes place three times in 24 h.
