HORRIBLE! Moved my Mom from her home to mine on 1/22. Wanted to change her service address to mine. Called Bay Alarm and sat on phone for over 45+ minutes and gave up. Contacted them by email, around 10 am, same day. A return email said "a customer service rep will contact you shortly," and I had my email and cell on the inquiry. "Shortly" is the operative word. It is now 1/24, 8 pm. and nothing! 2 1/2 days, to date, is not "shortly," when all you want to do is change the address where your 96 year old Mom is living, in case there is an emergency. After three years

Raul at Bay Alarm is the best!!!!!! I was searching far and wide for an alarm company to secure my bike shop. I wasn't satisfied with any of the companies until we met Raul. He came in and knocked out of the park for us. Quick turn around and he is always there for any questions. Highly recommended

When we purchased the new building for our company we were facing the challenge of a combined alarm and fire system. Our old alarm company simply wasn't up to the task of updating such a complex system. All their staff was such a pleasure to work with. From Dianna W. their office manager and Ben H our Rep to the installer Steve P. This company has been a pleasure to work with. My advice....sign up with them. THEY ARE DIALED

Commercial account. Installers are great. However, when you call for support, you are almost always put on a long hold. When you need someone to come out, they usually can't come for at least 2 days, unless you press really hard for them to come later in the day. When a tech arrives, they usually do a great job at resolving our issues. The software is difficult to manage if you have a large business, or make frequent changes. Not easy to change to another company if you are in contract, so do your research. My sales rep is not proactive- doesn't periodically follow up to see

Loved how they showed up on time each day. They wore their mask as safety is number one during these times. Very knowledgeable, professional. Bay Alarm did our whole office building installation of fire and burglar alarm system including cameras inside and outside of building. The remote view and arming and disarming is user friendly and available on your phone. The technicians are 5 star professionals, Jose Flores, Robert Villafuerte, and Armando Rosas went above and beyond In providing training and information.

We inherited Bay when they bought our alarm company (which had acquired our previous security firm), and they've been reliable for years. They're also consistently responsive, friendly, and always seem eager to help. But... certain things seem challenging, perhaps because upgrading an existing system introduces configuration problems that new installations avoid. Our original analog system is 30 years old and, when replacements were no longer available, we had to go digital. That required programming to replicate our settings and... that didn't go so well. Yet, after three valiant
