## Long description

Motion detector Ajax Motion Protect Pet immune black is a wireless indoor PIR sensor designed to detect human intrusion while ignoring pets that meet the manufacturer's weight and height limits. The compact black detector connects to Ajax Hub and provides digital signal processing, encrypted communication and long battery life for reliable monitoring of homes, apartments and offices with animals present.
Advantages
The detector covers motion up to 12 m and maintains communication with Ajax Hub at distances up to 1,700 m in open space. It uses authentication, encrypted transmission and frequency-hopping to protect against interference and fraud. SmartDetect algorithm together with a FresnelTech optical component and an Excelitas PIR sensor reduce false alarms from pets (up to 20 kg and 50 cm tall), drafts and electromagnetic interference. The device supports three sensitivity levels, digital temperature compensation and offers up to 7 years of battery life on a pre-installed CR123A cell.
