About Knight Security

About Us

Knight Security began as a division of one of San Diego’s largest electrical contractors, and incorporated on its own in 1974. Two generations later and now over 50 years in business, Knight Security is the largest, family-owned, Home Security Systems and Commercial Security Systems company in San Diego.

We believe the continued growth of our business is made possible by a commitment to excellence through honesty, integrity and reliability. Each system we design and install reflects these commitments.

Richard Mates, Knight Security President
