Photo enforcement parking software uses fixed or mobile cameras to automatically capture images of parking violations. Each photo is timestamped, GPS-stamped, and paired with license plate data to create a complete evidentiary record. Officers or automated systems review the captures and issue citations — no officer presence at the moment of violation is required.

Fixed cameras scan vehicles in a parking area continuously or at set intervals. When a violation is detected — such as an expired meter or permit violation — the system captures a photo, reads the license plate, verifies permit status, and queues the record for citation issuance. The full process takes seconds and creates a defensible evidentiary record.

Digital chalking replaces traditional tire-chalk marking with a mobile device or camera system that photographs a tire's valve stem position and records a GPS-stamped timestamp. When an officer returns, the system compares the new image to the original — if the vehicle hasn't moved beyond the time limit, a citation is issued automatically. No physical chalk is needed.

Digital chalking tracks time-limited parking violations by comparing tire images over time — used in zones where duration of stay matters regardless of payment. LPR enforcement reads license plates to verify permit status or payment in real time. Both are components of a modern parking enforcement platform; many cities use both depending on zone type.
