Description
The Dinsafer Helio DPMH1 is a wireless passive infrared motion sensor designed as an accessory for the Helio smart alarm system. It detects human body movement within a 110° field of view at up to 9 m, while its pet-immunity function prevents false alarms from animals weighing up to 20 kg.
Automatic temperature compensation keeps detection accurate across varying ambient temperatures. The sensor runs on two AA batteries and includes energy-saving and low battery warning functions, making it straightforward to install and maintain.
Key Features
