The GLSA-ODT/OIR-FP-500 Occupancy Sensor Lens provides fine-grained motion detection for rooms or sensing areas up to 500 sq ft. The lens affords greater versatility to the CrestronGLS-ODT-C-CN, GLS-ODT-C-NS, GLS-OIR-C-CN, and GLS-OIR-C-NS occupancy sensors, optimizing them for use in small rooms or spaces that require a high degree of motion detection sensitivity.
