1Degree Surveillance

1Degree Surveillance is a nationwide commercial remote video monitoring and CCTV monitoring provider that helps businesses detect, verify, and respond to security threats in real time. The service combines AI-powered threat detection with trained, U.S.-based security operators who monitor connected camera systems 24/7. When suspicious activity is detected, an operator reviews the live footage, follows the property’s customized response protocol, and takes immediate action. This can include issuing a live audio warning through on-site speakers, activating lights or sirens, notifying designated contacts, and coordinating a video-verified police dispatch when necessary. Unlike traditional surveillance systems that only record incidents for later review, 1Degree Surveillance turns existing security cameras into an active crime prevention solution. Its services include remote video monitoring, alarm video verification, virtual guard tours, real-time audio intervention, AI-assisted threat detection, and detailed incident documentation with time-stamped video clips and operator notes. 1Degree Surveillance works with most modern IP camera systems and supports single-site and multi-location businesses across the United States. Solutions are tailored to the specific risks of construction sites, automotive dealerships, truck yards, retail stores, parking facilities, industrial properties, commercial buildings, self-storage facilities, multi-family communities, and other high-risk commercial environments. By combining intelligent technology, live human verification, and real-time intervention, 1Degree Surveillance gives businesses proactive, scalable security without the cost and limitations of relying entirely on on-site guards.
