Defensor Robotics, a division of On Time Security, deploys autonomous on-site security systems and software across the United States and select international locations.
These solutions are designed to improve visibility, deterrence, and real-time awareness across a site. These systems and software combine professional monitoring hardware with an enterprise-grade software platform that continuously analyzes activity, identifies events, and generates alerts as they occur.
The system supports real-time monitoring, automated alerts, system-initiated audio response, and live communication when needed. Activity is recorded and documented automatically, providing consistent oversight across the site.
Autonomous security systems can be deployed as a standalone solution or as part of a broader security program to strengthen overall coverage and awareness.
Autonomous security systems monitor designated areas using integrated detection and response technology that actively identifies activity and provides immediate awareness.
Core capabilities include:
• Continuous monitoring of designated areas
• Real-time activity detection and alerting
• System-initiated audio response and live communication
• Visible system presence to deter unauthorized activity
• Automated recording and documentation of events
• Remote access to live and recorded activity
• Integration with existing security operations

Autonomous security systems provide consistent monitoring and faster awareness of activity across a site.
Continuous monitoring
Systems operate around the clock, maintaining visibility across designated areas.
Real-time alerts
Activity is identified and flagged immediately through integrated software.
Active deterrence
Visible systems and automated audio response help discourage unauthorized activity.
Scalable coverage
Systems can be deployed across single or multiple locations based on need.
Operational support
Autonomous systems strengthen visibility and coverage across the site.
Recorded documentation
Captured footage and system-generated records provide documentation when incidents occur.
Autonomous security systems are positioned based on the layout, size, and key areas of the site.
Coverage may include:
• Placement of monitoring units at key locations
• Coverage of entry points, perimeters, and high-traffic areas
• Real-time alert generation and monitoring
• Automated and live audio interaction when needed
• Integration with on-site personnel when applicable
• Ongoing system adjustments based on site conditions


Autonomous security systems are used in environments where consistent monitoring and visibility are important.
Typical applications include:
• Construction sites
• Commercial properties and office buildings
• Industrial facilities and warehouses
• Retail locations and shopping centers
• Parking areas and structures
• Vacant or temporarily unoccupied properties
• Storage facilities
• Large outdoor or open areas
Autonomous security systems are used to improve visibility, strengthen deterrence, and maintain consistent monitoring across a site.
These systems can help:
• Maintain awareness across large or complex areas
• Provide monitoring during off-hours
• Deter unauthorized activity
• Support broader security operations
• Improve response awareness through real-time alerts
On Time Security delivers autonomous security systems through its Defensor Robotics division to support both traditional and technology-based security strategies.
