MotionCam U.
Wireless PIR motion detector that takes photos by alarm
Standards and certifications
MotionCam U Jeweller · MC.S.J. Manufacturer-listed marks; regional and installation conditions apply.
An alarm with a picture of what happened.
MotionCam U Jeweller combines indoor motion detection with photos triggered by an alarm. HDR and infrared illumination help show the scene in contrasting or low light, so authorised viewers can assess the event. This model provides alarm photos; the PhOD version adds photo requests and other configured triggers.

Photos with a motion alarm
The armed detector takes a series of pictures when it detects motion, giving the system’s authorised viewers visual context for the event.
This MotionCam U model does not support photo requests, schedules or scenarios. Choose MotionCam U (PhOD) for those additional triggers.
Keep photo access under your control.
Control access to alarm photos
Manage access to alarm photos for individual users, installers and monitoring companies in the Ajax system’s privacy settings. Authorised viewers can open a photo or image series from the alarm notification in the event feed.
MotionCam U takes photos in response to its own motion alarm. On-demand photos, schedules and photo scenarios require the separate PhOD model.
Useful detail in light and shade.
HDR and infrared illumination
HDR combines different exposures to retain detail in bright and dark parts of the scene. Infrared illumination supports photos in low light.
Select 160 × 120, 320 × 240 or 640 × 480 px. The two lower resolutions allow 1–5 photos per series; 640 × 480 allows 1–3. Specified delivery is up to 7, 9 or 20 seconds respectively, under the stated conditions.
Detect movement across the protected room.
PIR sensing up to 12 m
The PIR sensor and Fresnel lens observe movement across an 88.5° horizontal detection area. Choose from three sensitivity levels in the Ajax app.
Install at 2.4 m with the likely intrusion path crossing the detection zone. This indoor detector is not designed for outdoor mounting.
Filter thermal interference.
SmartDetect analysis
The detector analyses the thermal pattern’s size, speed and intensity to distinguish an intrusion from common disturbances.
Fit the detector for the room and its pets.
Up to 20 kg and 50 cm tall
Correct placement at 2.4 m and suitable sensitivity help avoid alarms from normal pet movement within these limits.
Climbing furniture or moving close to the lens can defeat the intended separation. Test the actual room after installation.
Power you can keep track of.
Replaceable batteries
Two preinstalled CR123A batteries provide up to four years under the specified conditions. The app shows charge status and warns when replacement is needed.
Indoor use only: −10°C to +40°C, IP50 and IK04. Photo activity, image resolution, polling and signal quality affect operating life.
A secure link for events and photos.
Jeweller and Wings
Jeweller carries alarms, status and configuration; Wings carries photo verification. Both use encrypted two-way communication with a compatible Ajax hub or assigned ReX 2.
Up to 1,700 m in open space. Obstacles, radio conditions, resolution and the hub’s internet connection affect delivery.
Reach rooms beyond the direct radio link.
Plan the complete communication path
Use a compatible ReX 2 for both detector events and photo delivery. The original ReX does not carry MotionCam photos. Test the detector-to-extender path and the extender-to-hub path at their installed positions.
A range extender increases coverage, not the hub’s total device capacity. Ethernet on a supported extender is its connection to the hub; the detector itself stays wireless.
Protection that also watches itself.
Removal alerts
The tamper reports removal from the mounting panel. Secure the panel’s tamper fixing point and the holding screw, then test the removal event.
Connection and device status
Regular exchanges let the hub monitor the detector and report missing communication or a fault. Named events identify the device and room.
Connection-loss detection depends on the polling settings. Notifications require the configured system communication paths.
Authenticated communication
The hub authenticates the device during communication. Encryption protects exchanged commands and events against interception and spoofing.
Set up for the way the site works.
Connect
Scan the device QR code in the Ajax app, then assign a recognisable name and room. Check compatibility with the hub and any range extender before installation.
