Optex REDSCAN RLS-2020S

Optex RLS-2020S Laser Scanning Sensor

Overview

The Optex RLS-2020S is a laser-based perimeter detection sensor designed for outdoor security applications. This sensor delivers reliable intrusion detection by scanning a defined perimeter zone using laser technology, making it ideal for fenced properties, critical infrastructure boundaries, and outdoor access control points. The RLS-2020S integrates into comprehensive security systems, providing an additional layer of detection capability for integrators designing multi-layered perimeter security solutions.

Key Features

• Laser Scanning Technology: Uses focused laser beam to detect motion and intrusion attempts across a defined perimeter zone
• Outdoor Rated Construction: Built for exterior deployment with weather-resistant design suitable for variable environmental conditions
• Configurable Detection Zone: Allows adjustment of detection sensitivity and range to match specific site requirements and reduce false alarms
• Low Maintenance Profile: Laser-based detection eliminates moving parts associated with traditional mechanical sensors, reducing maintenance requirements
• Integration Capability: Provides standard alarm relay outputs for connection to access control systems, NVRs, and security management platforms
• Flexible Mounting: Supports multiple installation orientations on poles, walls, or fence structures for optimized perimeter coverage

Deployment Considerations

The RLS-2020S functions as a perimeter detection complement to video surveillance systems. Integrators typically deploy this sensor at property boundaries where early detection of unauthorized approach is critical. The laser scanning approach provides detection independent of lighting conditions, eliminating reliance on video analytics during low-light hours. When combined with camera systems, the sensor creates a layered detection strategy that improves response time to potential intrusions.

Outdoor installation of the RLS-2020S requires consideration of weather exposure, particularly in regions with heavy precipitation or fog that may temporarily affect laser transmission. Site assessment should include evaluation of the protected perimeter length and required detection depth to ensure proper sensor positioning and coverage. The device supports standard 12V DC power, making it compatible with conventional security system power supplies used across most integrator installations.

The RLS-2020S connects via relay outputs to existing control panels and alarm management systems, enabling automated response triggers when detection events occur. This relay-based integration approach ensures compatibility across diverse security platforms without requiring specialized software or firmware updates. Typical deployments include the sensor output wired to alarm input channels on access control panels, fire alarm systems, or NVR external alarm inputs for event correlation and logging.

Technical Integration

Integration of the RLS-2020S into a complete security architecture involves zone mapping and response configuration. Security integrators define which perimeter sections the sensor monitors and establish corresponding response actions—such as camera pan-to-point, alert generation, or access control lock-down. The sensor's alarm relay closure triggers these downstream actions, creating coordinated defense mechanisms. For systems requiring integration with ONVIF-based video management platforms, the RLS-2020S can be integrated via external alarm adapters or direct relay connections to the NVR system.

Karl Wilson

I've specified the RLS-2020S on several perimeter security projects where early detection of boundary intrusion provides critical response time. The laser scanning approach offers reliable detection without dependency on video analytics or lighting conditions, making it valuable for 24/7 perimeter monitoring. This sensor performs as a dedicated detection layer separate from camera systems, which enhances overall system resilience.

Technical Highlights:

• Detection Independence: Laser-based detection operates autonomously from video systems, providing continuous perimeter scanning regardless of image quality or environmental lighting
• Relay Integration: Standard alarm relay outputs integrate directly into existing access control panels and NVR systems without requiring protocol-specific interfaces
• Outdoor Durability: Weather-resistant construction supports year-round outdoor deployment across diverse climate zones

Deployment Considerations:

• Conduct site assessment to establish sensor placement that maximizes perimeter coverage while minimizing blind spots at property boundaries
• Configure detection sensitivity during commissioning to reduce nuisance alarms from weather effects while maintaining intrusion detection responsiveness
• Integrate relay outputs into the security system's alarm input channels to enable coordinated response actions across camera, access control, and notification systems
• Plan for routine testing during system maintenance cycles to verify laser transmission and relay functionality in outdoor weather conditions

The RLS-2020S is most effective as part of a layered security approach where perimeter detection combines with video surveillance and access control. Specify this sensor when your design requires independent, weather-independent intrusion detection at property boundaries where early detection improves response effectiveness.
