Commercial Door Security

Apr 2025

Tom is extremely professional and a true expert in business security. He offers free assessments and provides fair solutions that put his clients first. He helped us install security cameras, a door buzzer, an intercom, and an app-based door-locking system—and even went above and beyond to upgrade our door locks. Highly recommended. He’s our go-to professional for all things door security.

I feel so lucky to have found this company, they are so efficient, fast and flexible! I call two other companies and they are way slower, the quote were higher and they never follow up. Commercial Door Security is not about ripping you off, they suggest an alternative solution to my problem that saves me lots of money. I'm a happy customer.

Our office has been looking at installing access control for several years now. We went through several quotes and options with local companies over the years and just couldn't find a simple solution that would fit our needs. The price quoted was either ridiculously high or the work proposed was just over-complicated....until we came across CDS. Tom, the owner, was professional and extremely easy to work with. He did a site survey and prep a quote for us within a day. We also dropped by his showroom in City of Industry and got a live demonstration from him. We narrowed down the exact model of the equipment we plan to use and he got down to work on site within the week. The whole process was quick and easy. Tom did a great job guiding us through the process and the training on using the intercom and the app (for access control). And of course the price was fair and reasonable, compared to other local vendors. Will definitely recommend CDS for the great service.
