Due to limited resources many states use speed enforcement cameras—also known as photo or video enforcement—to take a digital photograph or video of a vehicle (and its license plate) that violates the speed limit. The use of speed enforcement cameras to issue speeding tickets or citations (mailed to the driver) has been controversial, with claims that it violates Constitutional rights.

Laws vary from state to state and in some states speed enforcement cameras are a permitted enforcement tool; in some states they are prohibited; and in some states they are prohibited unless permitted by a local ordinance (city or town).

To measure the speed of a moving vehicle and issue speeding tickets by photo enforcement, police departments generally use photo or video radar that relies on radio signals and the Doppler Effect or photo and video LIDAR (Light Detection and Ranging) technology that relies on lasers rather than radio waves. These devices require training on their proper use and regular calibration to be accurate.

In the state of Oklahoma, the use of speed enforcement cameras is not a common practice for issuing speeding tickets or citations. Oklahoma state law does not specifically authorize the use of automated photo or video enforcement systems for speed enforcement on state highways. While some states have embraced this technology, Oklahoma has not passed legislation that broadly permits the use of speed cameras. Therefore, traditional methods of speed enforcement, such as direct observation by law enforcement officers using radar or LIDAR devices, are the primary means of monitoring and enforcing speed limits in Oklahoma. These devices do require officers to be trained in their use and to perform regular calibration to ensure accuracy when detecting vehicle speeds.
