El Cerrito's video surveillance ordinance takes effect today, and police say that cameras installed early have come in handy in at least two cases over the past six months.

The ordinance calls for surveillance cameras at specific types of businesses in El Cerrito, to aid in solving and deterring crime.

"This is a proactive attempt on our part to reduce violence in our community, and keep business owners and patrons as safe as possible," said El Cerrito police Cmdr. Michael Regan.

Firearms dealers, stores that sell liquor, banks, check-cashing businesses, takeout food establishments, secondhand dealers such as pawn shops and stores selling used musical instruments or video games, and convenience stores all fall under the ordinance. The businesses also are required to allow El Cerrito police to inspect the equipment annually.

Regan said about 70 El Cerrito businesses are covered by the ordinance, and the city is working to make sure all comply.

"The majority (of the response) is positive. From the employees' perspective, they see it as a means of increasing their security," Regan said. The cameras have been used to help thwart the sale of stolen property and catch a robber, he said.
