Autonomous Security Units - Serving All 50 States + Puerto Rico

Defensor Robotics, a division of On Time Security, available in all 50 states and Puerto Rico, delivers robotic security systems that actively monitor, detect, and respond to threats in real time. These systems are built on the same enterprise-grade platform trusted in high-risk and high-traffic environments.  including select airports, infrastructure sites, and corporate campuses. 

The same software used to operate our units can also integrate with existing systems. It supports behavior detection, live alerts, audio response, and centralized monitoring, even without deploying new hardware. This allows organizations to add AI-powered threat response without replacing their current equipment.

Each robotic unit analyzes activity, identifies risk patterns, and takes action using built-in lights, sirens, voice-down capabilities, and instant notifications. Every response is based on actual behavior, not just motion.

We match each system to the layout and risk profile of your site. Whether you need fixed deterrents, tower coverage, interior response, or active patrol, we align the solution to your needs.

Fixed-Mount Units
Wall or pole-mounted. Best for entrances, perimeter coverage, and exposed areas. Includes cameras, lights, audio response, and alert triggers.

Mobile Tower Units
Self-contained solar trailers. Ideal for open lots, utility sites, or temporary deployments without permanent infrastructure.

Interior and Lobby Units
Compact devices for indoor coverage. Used for access control, visitor screening, or behavior monitoring in high-traffic areas.

Patrol Units
Autonomous robots that move across large properties. Provide visibility and active response for sites with broader exposure.

• AI-Powered Detection
  Analyzes behavior in real time. Detects loitering, perimeter breaches, or unusual activity with context-based accuracy.

• Built-In Deterrents
  Triggers lights, sirens, and pre-recorded or live voice alerts based on real threat signals.

• Remote Monitoring
  Secure video and audio access from anywhere. Operators can respond, monitor, and speak through devices in real time.

• Immediate Notifications
  Delivers alerts to your team with incident footage and relevant data the moment an issue occurs.

• Flexible Setup
  Most units require minimal installation and can be scaled or relocated as needed.

• Full Coverage Availability
  Deployed and supported across all 50 states and Puerto Rico. Software-only options available for teams using existing hardware.

Cameras only record what happened. Guard coverage might not be available 365 days a year. Defensor Robotics closes those gaps with technology that watches continuously, responds instantly, and helps prevent problems instead of just documenting them. These systems work on their own or alongside your existing security strategy to extend coverage, reduce blind spots, and help act faster when something’s off.
