Mijac Alarm

Bay Alarm Is Here to Meet Your Security Needs

We are excited to welcome you to the Bay Alarm family. Founded 75 years ago, we are the largest independently owned alarm company in the United States. Just like Mijac Alarm, Bay Alarm was started by a husband and wife with the goals of keeping their community safe while providing superior customer service.

Now in our third generation of family leadership, Bay Alarm has grown from a small office in Oakland, California, to serving communities across California, Washington, and Arizona. Despite our size, we still do things the “Bay Way,” which means you’re getting personalized service, professionally trained security specialists, and a company with deeply ingrained family values.

Please know that you don’t have to do anything as a result of this transition.

Our goal is to make this as easy as possible. We are working closely with the team at Mijac Alarm to reduce any impact to you and ensure everything is accurately transferred.

We encourage you to read the below FAQs if you have any questions. Thank you for the opportunity to protect what’s important to you! We look forward to keeping you, your families, and your businesses safe.

The Westphal Family and the Entire Bay Alarm Team
