Wireless IR motion detector
Standards and certifications
MotionProtect Jeweller · MP.Y.J. Manufacturer-listed marks; regional and installation conditions apply.
Notice movement where it matters.
MotionProtect Jeweller watches for changes in infrared radiation caused by movement through a protected room. Its detection algorithm evaluates the signal before raising an alarm, helping reduce unwanted alerts. Positioning and sensitivity can be matched to the room, with device status and settings available through the Ajax system.

How movement becomes an alarm.
PIR detection
An Excelitas PIR sensor detects changes in infrared radiation as a person moves through the area. The lens, mounting position and signal analysis determine reliable coverage.
Motion detection reaches up to 12 m when the detector is correctly installed and configured.
Power for everyday protection.
Replaceable battery power
A preinstalled CR123A battery supports up to five years of wireless operation. The app shows battery status so servicing can be planned.
Battery life depends on settings, use, temperature and signal conditions. Respond to the app’s low-battery notification.
A secure link to your system.
Jeweller communication
Jeweller carries alarms, status and commands between this detector and a compatible hub or range extender. The two-way link uses encryption and device authentication.
The stated range is up to 1,700 m in open space. Walls, metal and the actual installation reduce usable coverage.
Reach the areas your system needs.
Plan around walls and distance
Test the signal where the detector will be installed. If coverage is insufficient, select a compatible range extender; an Ethernet-equipped model provides another route back to the hub.
Range extenders are optional equipment. Check supported models and quantities against the exact hub before planning coverage.
Know that protection is working.
Device state in the app
The detector reports its condition to the hub. Communication, power and tamper information help identify a device that needs attention. Clear device and room names make an alert easier to act on.
Professional alarm monitoring is a separate service. Notification and connection-loss timing depend on system settings and connectivity.
Protection that also watches itself.
Removal alerts
The tamper reports attempts to remove the detector from its mounting panel. Secure the mounting arrangement and check that the event reaches the intended users.
Authenticated communication
The hub checks the detector’s identity during communication. Encryption protects the exchanged data, while authentication helps reject a device attempting to impersonate it.
Installed for your actual space.
Connect
Scan the device QR code to add it to a compatible hub. Assign a clear name and the room or area where it will operate.
