Ajax MotionCam U (PhOD) Jeweller White Wireless PIR Motion Detector with Photo Verification
The Ajax MotionCam U (PhOD) 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 and the full range of Ajax photo verification modes — including Photo on Demand, Photo by Scenario, Photo by Schedule and Photo by Arming/Disarming — in addition to alarm-triggered photography.
The "(PhOD)" designation distinguishes this detector from the standard MotionCam U Jeweller. While both share the same PIR detection hardware and Jeweller/Wings communication, the PhOD variant provides significantly extended photo capabilities, allowing authorised users to request images at any time and configure automated photo schedules — not just on alarm. The "U" designation confirms this is the model adapted to comply with UK regulatory requirements, making it the appropriate version for UK security installations.
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.
Extended Photo Verification — Five Modes
The MotionCam U (PhOD) Jeweller supports all five Ajax photo verification modes, giving installers and users the most complete set of visual monitoring options available in the Baseline indoor range:
-
Photo by Alarm — camera activates automatically when motion is detected in armed mode, delivering a series of images within approximately 9 seconds at the default 320×240 pixel resolution
-
Photo on Demand — authorised users can request a photo from the detector at any time through the Ajax app, regardless of alarm state
-
Photo by Scenario — the detector takes photos automatically when another Ajax device in the system triggers an alarm, enabling cross-device visual verification
-
Photo by Schedule — photos can be set to be captured at predefined times, supporting routine visual checks of protected areas
-
Photo by Arming/Disarming — the camera captures images each time the system is armed or disarmed, providing a visual record of access activity
This makes the MotionCam U (PhOD) Jeweller well suited to installations where visual monitoring, remote check-in or activity documentation is required, not just alarm response.
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 takes two exposures at different levels and merges them into a single optimised frame, helping to preserve detail in both bright areas such as windows and darker zones within the same scene.
In low-light or dark conditions, an infrared backlight activates automatically, enabling the camera to capture usable images without ambient light. 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 including those with air conditioning, heating vents or other thermal sources.
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 is adjustable across three levels in the Ajax app to suit different installation environments.
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 and anti-jamming detection
-
Wings — dedicated photo transmission protocol, delivering alarm and on-demand 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. On-demand photos are linked to the requesting user and are not transmitted to the security company monitoring station unless separately configured.
Long Battery Life
The detector is powered by two pre-installed CR123A lithium batteries, providing up to five years of operation under normal conditions before replacement is typically required — one year longer than the standard MotionCam U Jeweller, reflecting the calculated impact of the extended photo features on energy usage.
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.
Privacy and Data Security
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 per user. On-demand photos are linked to the user who requested them and are not automatically visible to monitoring station operators.
Designed for Professional Security Systems
The MotionCam U (PhOD) Jeweller is part of Ajax's Baseline product line and is adapted for UK regulatory compliance. It is suited to residential, commercial and office installations where both alarm-triggered photo verification and proactive visual monitoring capability are required within a single wireless detector.
