The Ajax MotionCam U Jeweller White is a wireless PIR motion detector with built-in photo verification, designed to provide accurate indoor intrusion detection with visual alarm confirmation. Featuring SmartDetect, pet immunity, encrypted Jeweller and Wings communication and up to four years of battery life, it is suited to expanding compatible Ajax security systems where visual verification is required.
Ajax MotionCam U Jeweller White Wireless PIR Motion Detector with Photo Verification
The Ajax MotionCam U Jeweller is a wireless indoor PIR motion detector designed for use in residential and commercial Ajax security systems. It combines passive infrared motion detection with a built-in camera that captures photographic evidence when an alarm is triggered, delivering visual confirmation to users and monitoring stations via the Ajax app. The "U" designation indicates this model has been adapted to comply with UK regulatory requirements, making it the appropriate version for UK security installations.
Using a highly sensitive PIR sensor together with SmartDetect digital signal processing and Wings photo transmission technology, the detector accurately identifies human movement, helps minimise false alarms and provides visual evidence of alarm events — all within a single device.
Reliable Indoor Motion Detection
The detector monitors indoor areas using a PIR sensor with a detection range of up to 12 metres, making it suitable for protecting hallways, living areas, offices, retail spaces and other internal rooms.
With a horizontal viewing angle of 88.5° and a vertical viewing angle of 80°, the detector provides effective room coverage when installed at the recommended mounting height of 2.4 metres, according to Ajax recommendations.
Photo Verification on Alarm
When motion is detected in armed mode, the MotionCam U Jeweller immediately triggers an alarm and begins capturing a series of photos using its built-in CMOS camera. These images are transmitted via the Wings radio protocol to the Ajax app, providing visual evidence of the alarm event within approximately 9 seconds at the default 320×240 pixel resolution.
This enables users and Central Monitoring Station operators to quickly assess the situation, helping to reduce unnecessary patrol dispatches and ease user concern during alarm activations.
The MotionCam U Jeweller takes photos only in the event of an alarm. It does not support Photo on Demand, Photo by Scenario or Photo by Schedule. If those features are required, the MotionCam U (PhOD) Jeweller is available separately.
HDR Image Technology
The detector uses HDR (High Dynamic Range) imaging to deliver clear, balanced photos in both bright and low-light conditions. The camera captures two exposures at different levels and merges them into a single optimised frame, helping to preserve detail in both bright areas (such as near windows) and darker zones within the same scene.
In low-light conditions, an infrared backlight activates automatically, enabling the camera to capture images in darkness. In these conditions, photos are produced in black and white.
SmartDetect False Alarm Prevention
The detector uses SmartDetect digital signal processing to analyse movement patterns and improve detection accuracy.
This technology helps distinguish genuine human movement from common sources of false alarms, providing more dependable operation in everyday environments.
Pet Immunity
When installed correctly, the detector is designed to ignore pets weighing up to 20 kg and measuring up to 50 cm in height.
This allows the system to remain armed while many household pets move freely throughout protected areas, helping to reduce unnecessary alarm activations. Sensitivity level also affects pet immunity and can be adjusted in three levels via the Ajax app.
Jeweller and Wings Wireless Communication
The detector communicates with the hub using two of Ajax's proprietary wireless protocols working in parallel:
-
Jeweller — transmits alarm signals and events with encrypted two-way communication, device authentication, frequency hopping protection and anti-jamming detection
-
Wings — dedicated photo transmission protocol, delivering verified alarm images securely to Ajax Cloud and the Ajax app
Communication range between the detector and hub is up to 1,700 metres in open space. Both protocols use block encryption with a dynamic key to protect all transmitted and stored data.
Long Battery Life
The detector is powered by two pre-installed CR123A lithium batteries, providing up to four years of operation under normal conditions before replacement is typically required.
Battery status is continuously monitored and reported to the Ajax app, with early low-battery notifications sent well in advance to allow planned maintenance.
Quick Professional Installation
The included SmartBracket mounting panel enables straightforward installation without needing to disassemble the detector body.
A built-in tamper switch detects any attempt to remove the detector from its mounting surface and immediately notifies the system, adding an additional layer of protection against interference.
Privacy and Data Security
The MotionCam U Jeweller takes photos only on alarm. The device's software architecture does not support on-demand image capture. All photos are encrypted throughout transmission and stored securely in Ajax Cloud. Only system users and security professionals with access to the event feed in the Ajax app can view images. The Privacy menu in Ajax apps provides precise control over visual data access permissions.
Designed for Professional Security Systems
The MotionCam U Jeweller is part of Ajax's Baseline product line and is adapted for UK regulatory compliance. It is intended for use within compatible Ajax security systems in residential, commercial and office environments, providing combined motion detection and visual alarm verification in a single wireless device.
