Commercial Alarm Co

Los Angeles has 38 home security listings on this page, but the numbers behind that count matter more than the total. Phone numbers show up on 37 of them and websites on 31, so most entries give you a real way to reach someone. None of the 38 are labeled Sponsored, since paid placement hasn't launched for this category yet, so you're looking at the plain default order rather than anything picked or promoted. Listings cluster around a handful of zip codes, including three in 91406 and two each in 90007, 90011, 90043, and 91356, which can help narrow things down if you're comparing installers near a specific neighborhood.

Nobody here has been verified by SiteCity, so treat the directory as a starting point for calls, not a ranking. If a listing is missing a website or the phone field looks off, the business owner can claim it and fill in current details, which saves the next person in Los Angeles a dead-end call. Worth calling two or three companies directly to compare what they offer before deciding, especially since a working number is your fastest way to get real answers about installation, monitoring, and pricing.
