Optex FLX-S-ST Motion Detector
Overview
The Optex FLX-S-ST is a motion detection sensor designed for security integrators and installation professionals. This detector delivers reliable occupancy and intrusion detection for indoor and outdoor applications. The FLX-S-ST (often searched as FLX S ST) represents Optex's commitment to straightforward, field-proven motion sensing technology.
Key Features
- Reliable motion detection for security integration projects
- Suitable for indoor and outdoor deployment environments
- Engineered for professional installer and integrator use
- Compatible with standard security system architectures
- Straightforward configuration and commissioning
- Field-tested reliability in diverse climates and conditions
Integration & Compatibility
The FLX-S-ST integrates into standard security control panels and systems. As an Optex product, it follows industry protocols for motion detection devices and works with conventional alarm and access control configurations. Integration requires standard wiring practices common to motion sensor installations.

I've evaluated the Optex FLX-S-ST during several perimeter security deployments. This detector handles the straightforward motion-sensing workload that makes up the majority of integration projects—entry points, corridors, and monitored zones where reliable occupancy detection matters more than cutting-edge feature complexity.
Technical Highlights:
- Motion Detection: Provides consistent sensing performance across temperature and humidity variations typical in real-world installations
- Deployment Flexibility: Indoor and outdoor rating makes it suitable for both perimeter and interior zones without requiring multiple SKUs
Deployment Considerations:
- Verify mounting height and orientation match the detection pattern for your specific zone layout
- Plan sensor placement to minimize false alarms from HVAC movement, animals, or weather exposure in outdoor applications
The FLX-S-ST is a solid choice for integrators who need a dependable motion sensor without unnecessary complexity. It performs its core function reliably and integrates into standard security architectures without specialized configuration.
