Assembly Bill 576 aims to regulate the use of automatic registration plate readers (ALPRs) and data from private security cameras by establishing a ban on their use, with specific exceptions. The bill allows ALPRs to be used by parking enforcement entities, for access control in nonpublic areas, and at weigh stations for commercial vehicle compliance. It mandates that any data collected must be limited to registration plate numbers, timestamps, locations, and images of the vehicles and surrounding areas, and requires that this data be kept confidential and destroyed within 90 days of collection.

Additionally, the bill stipulates that law enforcement agencies must obtain a search warrant to access data from private security cameras or ALPRs, except in emergencies where there is a risk of death or serious injury. Violating this prohibition is classified as a misdemeanor, punishable by a fine of up to $10,000. The bill also outlines the process for obtaining a warrant, including provisions for secrecy and the destruction of data after criminal proceedings. Overall, the legislation seeks to enhance privacy protections while allowing for necessary law enforcement activities under strict conditions.
