Home security sensor designed to guard doors and windows with combined glass-break and motion detection, the AJAX Combi Protect W Window Break Detector promises targeted protection. Peace of mind comes from pet-aware sensing and long service intervals that suit busy households. Is this sensor the right fit for typical UK homes that need discreet, low-maintenance protection?
⚡ At a Glance
- • Detection Capability: Combined glass-break and motion sensing for targeted window and door protection
- • Best for: Homeowners wanting unobtrusive, targeted protection of windows and doors
- • Not ideal for: Properties that require whole-home coverage from a single device
Combined glass-break and motion sensors protect openings, while wireless operation keeps installation tidy. Designed primarily for monitoring the condition and security of windows and doors.
Detects break-ins and forced entry - with dual glass-break and motion sensors
Dual sensing monitors glass break events and movement, with motion detection reaching up to 12 m and glass-break detection up to 9 m. Wireless signalling reports the current condition of the monitored window.
Both smashed glass and suspicious movement can be picked up, so an attempted entry through a window or door is less likely to go unnoticed. Targeted sensing reduces the need for multiple separate detectors on the same opening.
Low-maintenance operation - thanks to long battery life
Rated for operation without battery replacement for up to five years according to the manufacturer. The unit uses battery power rather than mains wiring.
Years of service without swapping batteries means less ongoing upkeep and fewer scheduled visits to replace cells. Reliable long-term operation suits busy households and rental properties.
Fewer false alarms around pets - with pet-immune motion sensing
Detection logic ignores cats and dogs weighing up to 20 kg and up to 50 cm tall. Motion sensing therefore focuses on human-sized intrusions while filtering out common household animals.
Homes with typical pets will experience fewer nuisance alarms, keeping alerts meaningful and reducing alarm fatigue. Owners can place units in living rooms or near frequently used windows without constant false triggers.
