Does highway violation surveillance include speed measurement?
1 Answers
Highway violation surveillance and speed measurement photography are not the same thing. 1. Different photography methods: Speed measurement photography uses high-speed, high-sensitivity cameras and flash with sensing devices. Induction coils are installed on the photography equipment, which automatically flash when a vehicle enters, indicating the detection of a vehicle. Surveillance photography uses conventional cameras, mainly for observing traffic flow and road conditions. To determine whether a vehicle is speeding, surveillance photography requires at least three or more photos as evidence. 2. Different purposes: Speed measurement photography aims to prevent speeding, while violation photography aims to prevent rule-breaking. On regular roads, speed limits of 70 and 50 are common, though drivers generally cannot speed in these areas. Many places have speed bumps for speed measurement. It's a good habit to slow down to below 70 upon hearing the alarm. When sensing a vehicle, the camera takes at least two photos—one of the front and one of the rear. If the photos are clear, they are automatically transmitted to staff for screening and processing. 3. Different camera principles: Speed measurement photography and surveillance photography use two different types of cameras. One is a regular camera for capturing lane violations, and the other is specifically for speed measurement. The speed measurement camera system is more expensive. From a cost perspective, not all surveillance cameras can measure speed, but speed measurement cameras have the functionality of regular cameras.
