Ajax MotionProtect Black Wireless Pet-Immune Indoor Motion Detector

Ajax MotionProtect Black Wireless Pet-Immune Motion Detector

The Ajax MotionProtect is a compact wireless PIR motion sensor built for indoor intrusion detection, designed to trigger alarms only on human movement while ignoring household pets. Powered by the encrypted Jeweller radio protocol, it connects instantly to any Ajax hub and reports events straight to the Ajax mobile app, making it a reliable core component for home and small business security systems.

Key Features

• Pet-immune detection: Ignores animals up to 20 kg and 50 cm tall when installed and configured correctly, reducing false alarms.
• Wide coverage: Monitors a 12-metre radius, suitable for most rooms, hallways and open living areas.
• Long wireless range: Communicates with the hub over the Jeweller protocol at distances of up to 1,700 metres in open line of sight.
• Long battery life: Runs on a single pre-installed CR123A battery rated for up to 5 years of use.
• Encrypted, two-way communication: Uses block encryption with a dynamic key and sends sabotage/jamming notifications for added protection.
• Fast, tool-free installation: Mounts via the included SmartBracket panel without needing to open the housing, and pairs with the hub by scanning a QR code.
• Smart temperature compensation: Automatically adjusts sensor sensitivity as ambient temperature changes to keep detection accurate.
• Remote configuration: Sensitivity and settings can be adjusted remotely through the Ajax app, avoiding unnecessary site visits.
• Discreet black housing: Sleek, low-profile design that blends into most interior colour schemes.

Ideal for Homes and Offices with Pets

This detector is best suited to indoor spaces such as living rooms, hallways, offices and retail areas where households or workplaces have cats or small-to-medium dogs. Because it filters out animal-sized heat signatures, it can be armed even when pets are left roaming inside, while still reliably catching human intrusions from the very first step. It integrates directly into any existing Ajax wireless alarm system alongside hubs, sirens and other Jeweller-protocol sensors.
