Optex LRP4010S Super Redwall LRP4010S, 3020S and 404S sensors are specifically designed for use in small to medium sized external areas. Their rugged construction and reliable operation make them ideal for use as motion detectors in CCTV applications. The inclusion of dual sensors and processors plus high and medium sensitivity settings results in a full specification sensor for the smaller installation. Patented double conductive shielding helps reduce false alarms caused car headlights and reflected sunlight. The head adjustments are tamper protected to prevent sensors being re-aligned by unauthorised personnel.
