Excalibur technicians have over 20 years experience in the home security industry. We are committed to offering exceptional customer service and the most value for your hard-earned dollar. We are licensed by the Texas Department of Public Safety Regulatory Services Division (Lic. #B28463701).

San Antonio is a special place. Why trust your protection to someone halfway across the country who can't pronounce "Bexar" County? We're from here. We're locally owned, operated, and monitored.

Excalibur is a small, San Antonio-based business. We're an authorized service provider for Alarm.com, the same industry-leading technology that more prominent companies use. We offer the same levels of alarm system customization with no contract and courteous, professional service.
