Assembly Bill 576 aims to regulate the use of automatic registration plate readers (ARPLs) and data from private security cameras by establishing a ban on their use, with specific exceptions. The bill allows ARPLs to be used by parking enforcement facilities, for access control in nonpublic areas, and at weigh stations for commercial vehicle compliance. Entities permitted to use ARPLs are restricted to collecting limited data, including registration plate numbers, timestamps, and images, which must be kept confidential and destroyed within 90 days.

Additionally, the bill mandates that law enforcement agencies must obtain a search warrant to access data from private security cameras or ARPLs, except in emergencies involving imminent danger. Violating this prohibition is classified as a misdemeanor, punishable by a fine of up to $10,000. The bill outlines the process for obtaining a warrant, including the requirement for probable cause and provisions for maintaining the secrecy of the warrant until it is executed. It also prohibits the use of facial recognition software on the data obtained and ensures immunity from civil liability for individuals complying with the warrant.
