SATEL OPAL Plus Dual-Technology Outdoor Motion Detector with Anti-Masking, IP54, White

Security installers protecting building perimeters rely on the SATEL OPAL Plus to reliably detect intruders in harsh outdoor environments. This dual-technology motion detector combines passive infrared (PIR) and microwave (MW) sensing with active infrared anti-masking, ensuring dependable performance even in rain, snow, strong sunlight, or gusty winds. Its auto-tuning algorithm continuously adjusts sensitivity to changing ambient conditions, minimizing false alarms while maintaining high detection accuracy. The OPAL Plus is suitable for both outdoor and challenging indoor installations such as covered walkways, halls, and entrances exposed to drafts or temperature fluctuations.

Why choose it

The OPAL Plus stands out with its robust dual-technology detection and anti-masking capability, which together provide a high level of security against both intruders and tampering. The automatic environmental compensation ensures stable operation across a wide temperature range and in adverse weather, reducing service calls. Its IP54-rated, UV-resistant enclosure is built to withstand outdoor exposure, while the integrated dusk sensor adds convenience for controlling lighting or other devices. The detector's low-current output allows direct interfacing with alarm control panels or home automation systems without additional relays.

Ideal use cases

• Outdoor perimeter and facade motion detection
• Indoor areas with difficult environmental conditions (covered walkways, halls, loading docks)
• Integration with alarm systems and home automation for lighting control
• Protection of entrances, driveways, and courtyards

Good to know

The OPAL Plus supports ceiling or wall mounting at a recommended height of 2.4 m. It includes a protected look-down zone to detect attempts to approach or remove the device. The detector is available in white and is supplied without a mounting bracket (bracket sold separately). For optimal performance, ensure the detection area is free from moving objects that could cause false alarms, and adjust the microwave range according to the installation environment.
