Michigan State Police is investigating the source of its malfunctioning dash cams.

In March, an officer was involved in an incident that led to a man being hospitalized and charged with a felony. The vehicle's camera began recording during the traffic stop when the patrol car’s lights were activated, but it did not write the recording to the memory card, reports the News-Review. At the time, it was determined that Michigan State Police did not tamper with the video or memory card, but a cause was not identified.

This week, a spokesperson for Michigan State Police said the malfunction is affecting patrol vehicles at every post in the state. About half of the police fleet uses the in-vehicle camera from Digital Ally. Digital Ally has released a software remedy that it believes may resolve the malfunction, but in the meantime, M Live reports that Michigan State Police is seeking a new camera system.
