About

Established in 1984, Peninsula Security has become a trusted source for custom security, camera and fire systems in the South Bay.

Our founder and president, Mark Rosenfeld firmly believes in doing business the “old- fashioned way, while staying current technologically.”

We believe this philosophy sets us apart. As such, our clients can expect:

  • Products, design and installation of the highest quality, customized to meet unique security concerns and lifestyle.  We provide complete security.

  • Courteous and friendly client care to help with any questions or concerns. We value our client relationships.

  • Only Peninsula Security technicians will install and service your systems- never subcontractors. This ensures that work is completed to Peninsula Security standards of quality.

We believe in the quality of both our workmanship and client care.

  • We do not retain our client relationships with high cost, long-term contracts. We retain relationships with quality and care.

  • Our equipment is non-proprietary, and you own it. 

  • We offer the latest in technology: You may supplement your security system with Alarm.com technology, which enables remote access and control of your system using a smart phone or computer.  Receive customized text or email messaging about real time emergency and non-emergency activity at your home or business.
