Ajax MotionCam U Jeweller | Wireless Motion Detector with Photo Verification | Pet Immune

FAQs

How does photo verification work with the MotionCam U Jeweller?

When the MotionCam U Jeweller detects motion while armed, it immediately sends an alarm notification via the Jeweller protocol (within 0.3 seconds) and simultaneously captures a series of 1 to 5 photographs using its integrated camera. These images are transmitted to the Ajax hub via the Wings protocol and appear in the Ajax apps as either individual photos or animated series, allowing users and security personnel to instantly assess the nature of the alarm. The HDR feature combines two shots with different exposures to provide clear detail in both bright and dark areas of the scene, while infrared illumination enables photography even in complete darkness, producing black and white images in low-light conditions.

Will the detector trigger on my pets?

When properly installed at the recommended height of 2.4 meters and configured with appropriate sensitivity settings, the MotionCam U Jeweller does not react to pets weighing up to 20kg and measuring up to 50cm in height. The SmartDetect algorithm with temperature compensation analyzes movement patterns and thermal signatures to distinguish between human intrusion and pet activity. The Low sensitivity setting provides immunity to pets up to 50cm height, Normal sensitivity (default) handles small dogs up to 35cm, and High sensitivity is designed for cats up to 25cm. However, proper installation is critical—the detector must be positioned so that the intended intruder path crosses perpendicular to the detector lens rather than approaching directly toward it.

What is the difference between Jeweller and Wings protocols?

The MotionCam U Jeweller uses two separate wireless protocols for different communication purposes. Jeweller is the primary protocol used for transmitting alarms, events, device states, and system commands, with exceptional speed (0.3-second alarm delivery) and reliability. Wings is a specialized protocol designed for transmitting larger data packets, specifically the photo verifications from MotionCam devices. While Jeweller prioritizes speed for immediate alarm notification, Wings is optimized for efficient transfer of image data, typically delivering photos within 18 seconds via wireless connection or up to 10 seconds if the hub has Ethernet connectivity. Both protocols operate in the 868.0-868.6MHz frequency band (or region-specific equivalents) and provide encrypted, authenticated communication with anti-jamming protection.

How long do the batteries last and what type are required?

The MotionCam U Jeweller operates on two CR123A batteries that come pre-installed with the device. Under typical operating conditions, these batteries provide up to 4 years of operation before replacement is required. The actual battery life depends on several factors including alarm frequency, number of photos taken, wireless signal strength, polling interval settings, and ambient temperature. The Ajax system monitors battery levels continuously and provides early low-battery notifications through the apps, giving users ample time (up to 2 months) to replace batteries before the detector stops functioning. The device will also indicate low battery status through its LED indicator, which slowly lights up green and goes out when an alarm is triggered.

Can the MotionCam U Jeweller be used outdoors?

No, the MotionCam U Jeweller is designed exclusively for indoor use only. The device has an IP50 protection rating, which provides protection against dust ingress but offers no protection against moisture or water. Installing the detector outdoors would expose it to temperature extremes, humidity, precipitation, and direct sunlight—all of which can cause false alarms, device malfunction, or permanent damage. For outdoor motion detection with photo verification, Ajax offers the MotionCam Outdoor Jeweller, which is specifically engineered with appropriate weatherproofing and environmental protection for external installation.

What is the communication range and how can it be extended?

The MotionCam U Jeweller communicates with Ajax hubs over distances up to 1,700 meters in open space on both Jeweller and Wings protocols. However, in real-world installations, the effective range depends on building construction materials, wall thickness, and sources of radio interference. The recommended signal strength is 2 to 3 bars as displayed in the Ajax app. If signal strength is insufficient at the desired installation location, the communication range can be extended using the ReX 2 Jeweller wireless range extender, which can be positioned between the hub and detector to relay signals. Note that the MotionCam U Jeweller is not compatible with the original ReX Jeweller range extender—only the ReX 2 Jeweller model is supported. Up to 5 ReX 2 Jeweller units can be used in a single system to cover extensive facilities.

How many photos does the detector take and at what resolution?

The number of photos and resolution are user-configurable through the Ajax app settings. The detector offers three resolution options: 160×120 pixels, 320×240 pixels (default), or 640×480 pixels. At the two lower resolutions (160×120 and 320×240), the detector can capture between 1 and 5 photos per alarm event. At the highest resolution (640×480), the detector can capture up to 3 photos per series due to the larger data size of each image. Higher resolution provides more detail for alarm assessment but takes slightly longer to transmit to the hub. Users can also configure how many alarm events will include photo verification—from every alarm to a specific count (1 to 10 alarms), with the counter resetting each time the system is disarmed and re-armed.

Can the detector be integrated with professional monitoring stations?

Yes, the MotionCam U Jeweller fully supports integration with professional central monitoring stations (CMS) through multiple industry-standard protocols including SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other formats. The detector transmits comprehensive event information including motion alarms, visual alarm verifications, tamper alerts, connection status, and battery status. The addressability of Ajax devices ensures that monitoring station operators receive detailed information about the specific device name, type, assigned room, and security group. Photo verifications are also transmitted to monitoring stations if the CMS software supports this feature—a list of compatible monitoring station software is available on the Ajax website. Ajax PRO Desktop monitoring application supports photo verification natively without additional configuration.
