Three friends from high school began their business in a garage in Fremont, producing and installing car alarm systems under the name Trojan Security. After several hundred installations, the focus transitioned to providing installation and monitoring for security systems in different facilities. We added more services and secured the necessary contractor's licenses. We rebranded to Trojan Systems, Inc. Tom Martin has been with us since the beginning.
A proud Bay Area resident, I completed my education in Fremont and earned a BS in Computer Science from Cal State Hayward. My dad, a pioneer in Bay Area security distribution, introduced me to the security field while I was in high school. I look forward to helping clients with my extensive experience.

Recommended Customer Reviews

I have been a customer of Trojan Alarm for the past 30 plus years. They have always provided excellent service on all of our new home projects. I highly recommend them.

We've been with Trojan Systems since we built our home in 1999 and have always been satisfied with their service and dependability. A recent upgrade to our system promises to make things even better. A special shout-out to Tabatha and Jessica, who are very personable, professional, and reliable. And

Zero star if that was possible. Absolutely terrible customer service and the system is faulty all the time: the central fire alarm system would beep very loudly every 7 seconds during the middle of the night when nothing was going on. We called the customer service and were told that the system was normal. We had to get up from bed at middle of the night to silence the alarm almost EVERY NIGHT. So be prepared to buy and use ear plugs every night if you want to use their service as our calls and emails were ignored and the company did not show any respect to customers. Stay away!

Their alarm systems are pretty archaic - pathetic smartphone app and very cheap keyboards (no display). Customer service wise only slightly better than the big name alarm companies to deal with.

Great service. It was a little confusing getting the tech sent out to our house, but ultimately the job got done to our satisfaction (fixing an outlet). The tech not only fixed it, but also found the source of the problem too. Efficient, not too expensive, and professional. Thanks Stefan!

We reached out to a number of businesses to do some backyard electrical work.
Trojan was great! Marcus was really prompt to respond. His office staff were a pleasure to work with. The work was done quickly and exceptionally well. The price was extremely reasonable.
I highly recommend Trojan to anyone in need of electrical work!

We were looking to upgrade our home security system and install a CCTV system. Tom came out on time, took a close and careful survey, and made a professional recommendation with options for us to consider and quotes. His team was absolutely outstanding, professional and pleasant to work with. They finished all the projects on time and left my place clean. Their office support has been awesome and responsive as well. Definitely 5 stars! My neighbor recommended Tom/Trojan Systems to us and I'm now recommending them to our other neighbors and friends.

Had new washing machine & dryer delivered in an afternoon only to find out that the 220 outlet did not meet code. After not having a these appliances for a week need electrician fast. Looked at Yelp and called one high rated electrician and their response to my sense of urgency: will send estimator out in 1 to 2 days price the job and if I agreed with estimate electrician would be out in 1 or 2 more days. Thanks but no thanks. I called Trojan about 4:30 pm they listened to my issue and they had an electrician to my house 7 am the next morning & receptacle replaced in 30 minutes. WOW! These guys are great. Would call them again with hopefully with no ""emergency"". Call Trojan.

This business was recommended to me by the contractor that built my home. I have a very specialized lighting system in my home and I had not been able to find one electrician willing or able to fix a problem that I had been dealing with for over four years. I am extremely pleased with the work that was done. The communication, work, and ease of scheduling will be a determining factor whenever I have another electrical job to do. I highly recommend this business!

Trojan Systems installed in-ceiling surround sound speakers in our family room and wired them to our home music/TV system early this year. Tom Martin and his crew exhibited a high degree of professionalism and skill and did a great job. The quality of the speakers they recommended is great, and we are extremely happy with the quality of sound when we watch TV, movies or listen to music.
