- adjustable sensitivity of motion detection
- digital algorithm of motion detection
- digital temperature compensation
- lens designed specifically for SATEL short range curtain detectors
- encrypted two-way radio communication in the 868 MHz frequency band (AES standard)
- diversification of transmission channels - 4 channels allow automatic selection of one that guarantees transmission without interference with other signals in the 868 MHz frequency band
- remote detector firmware update
- remote configuration
- built-in temperature sensor (temperature measurement from -10 °C to +55 °C)
- LED indicator
- monitoring of motion detection system
- ECO option to extend battery life
- battery check
- tamper protection against opening the enclosure and against detaching it from mounting surface

The device is operated by:

- ACU-220/ACU-280 system controller
