Ajax MotionCam Outdoor HighMount (PhOD) Jeweller White is a wireless outdoor PIR motion detector with dual motion detection technology and the full suite of Ajax photo verification modes. Designed for high-mount installation between 2 and 4 metres, it combines two PIR sensors and a K-band microwave sensor to help eliminate false alarms, while a built-in camera captures visual evidence on alarm, on demand, or on schedule. Suited to warehouses, industrial complexes, construction sites, car parks and larger residential perimeters.

Ajax MotionCam Outdoor HighMount (PhOD) Jeweller White Wireless Outdoor PIR Motion Detector with Photo Verification

The Ajax MotionCam Outdoor HighMount (PhOD) Jeweller is a wireless outdoor motion detector designed specifically for elevated mounting positions between 2 and 4 metres, providing wide-area coverage with no blind zones in the immediate vicinity below. It is intended primarily for remote locations, warehouses, industrial complexes, construction sites and other commercial or perimeter environments, though it is equally suited to larger residential properties and offices where high-level exterior detection is required.

The detector combines dual PIR sensors with a K-band microwave sensor for a two-stage motion verification process, significantly reducing false alarms from environmental factors such as swaying branches, air flows and heat sources. A built-in camera delivers photo verification in five modes via the Ajax app, including Photo on Demand, making visual confirmation available both reactively on alarm and proactively at any time.

High-Mount Outdoor Detection

The MotionCam Outdoor HighMount (PhOD) is designed to be mounted on a vertical surface at a height of 2 to 4 metres. This elevated position provides an optimal vantage point that eliminates the blind zones directly in front of a ground-level detector, making it well suited to corners, building facades, perimeter walls and industrial structures where movement needs to be detected across a wide area from above.

From this mounting height, the detector provides a motion detection range of up to 15 metres, a horizontal viewing angle of 90° and a vertical viewing angle of 90°. The metal swivel mount allows the tilt angle to be precisely adjusted during installation to suit the specific mounting position and coverage area required.

Important: The MotionCam Outdoor HighMount (PhOD) Jeweller does not support pet immunity. This detector is designed for outdoor perimeter protection and its dual-sensor technology is optimised for human detection at height. It is not recommended for environments where animals frequently cross the detection zone.

Dual Motion Detection Technology

The detector uses two complementary detection methods working in sequence to improve accuracy and minimise false activations:

• Two PIR sensors — one covering the near-field detection zone and one covering the far-field zone, together providing continuous coverage across the full 15-metre detection range
• K-band microwave sensor — activated after initial PIR detection, performing radio frequency scanning of the zone to confirm genuine movement and filter out thermal interference such as heat from roads, lighting devices, air flows and other environmental sources

The device triggers an alarm only when both the PIR and microwave sensors confirm movement. This dual confirmation process, combined with a Fresnel lens that differentiates between the PIR signatures of people and thermal noise, helps ensure the detector responds to genuine intrusion rather than environmental false triggers.

SmartDetect and LISA False Alarm Prevention

At the software level, the detector uses the SmartDetect algorithm to analyse the thermal diagram from the PIR sensors, including infrared radiation intensity, heat spot size, movement speed and dwell time within the detection area. A secondary LISA (Linear Integrated Signal Analysis) algorithm performs additional correlation and spectral analysis of movement patterns before an alarm is raised.

Three sensitivity levels — Low, Normal and High — can be adjusted through the Ajax app to suit the specific characteristics of the installation environment.

Anti-Masking Protection

The detector includes a built-in anti-masking system that detects attempts to block or obstruct the detector's field of view — whether by placing an object in front of the sensor, painting over it, or taping it. The system notifies users and the monitoring station of any masking attempt, with a maximum detection time of up to 180 seconds depending on the type and distance of the obstruction. Anti-masking is always active regardless of the current security mode.

Extended Photo Verification — Five Modes

The MotionCam Outdoor HighMount (PhOD) Jeweller supports all five Ajax photo verification modes:

• Photo by Alarm — a series of up to 5 photos is automatically captured when motion triggers an alarm in armed mode; the first image is delivered within approximately 9 seconds at the default 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 — photos are captured automatically when another device in the Ajax system triggers an alarm, enabling cross-device visual verification
• Photo by Schedule — images are taken at predefined times, supporting routine visual checks of protected outdoor areas
• Photo by Arming/Disarming — photos are captured each time the system security mode is changed, providing a visual log of access activity

Photos are displayed in the Ajax app to users with appropriate access rights and can be shared with Central Monitoring Station operators for visual alarm verification, helping to reduce unnecessary patrol dispatches.

HDR Imaging and IR Illumination

The built-in camera uses HDR (High Dynamic Range) imaging to deliver clear, balanced photos across scenes with mixed bright and dark areas — useful outdoors where lighting conditions change between day and night or where artificial lighting creates high-contrast environments. An infrared illuminator activates in low-light conditions, enabling photo capture in darkness. Images taken in these conditions are produced in black and white.

Jeweller and Wings Wireless Communication

The detector communicates with the hub using two Ajax proprietary wireless protocols working in parallel:

• Jeweller — encrypted two-way transmission of alarm signals and events, with device authentication, frequency hopping and anti-jamming detection
• Wings — dedicated photo transmission protocol, delivering images securely to Ajax Cloud and the Ajax app

The wireless communication range is up to 1,700 metres in open space. Both protocols use block encryption with a dynamic key. Firmware updates are delivered over the air via the Wings channel and do not require an external power supply to be connected.

Power Supply and Battery Life

The detector is powered by six pre-installed CR123A lithium batteries, providing up to 3 years of operation under normal conditions. A 12–24V DC external power supply can also be connected; when an external supply is present, the pre-installed batteries serve as a backup power source in the event of a mains failure. This makes the detector suitable for both battery-only deployments, including off-grid security towers, and mains-supplemented installations.

Battery status is monitored and low-battery notifications are sent through the Ajax app well in advance, allowing planned maintenance before battery replacement is critical.

Weather Protection and Operating Range

Rated IP55, the detector is protected against dust ingress and water jets from any direction, making it suitable for outdoor installation in UK weather conditions. It operates across a temperature range of −25°C to +60°C and up to 95% humidity. A hood is included in the box, which protects the camera lens and anti-masking sensors from direct rain and snow — particularly important for maintaining photo quality and anti-masking reliability during adverse weather.

Security Tower and Off-Grid Applications

The MotionCam Outdoor HighMount (PhOD) is particularly well suited to autonomous security tower configurations. Multiple detectors can be mounted on a support structure to provide 360° coverage, connected to a Hub BP Jeweller powered by an external battery and combined with an outdoor siren. This creates a fully self-contained, off-grid intrusion detection system suited to temporary or remote sites such as construction sites, seasonal storage facilities and event spaces where mains power is not available.

Professional Installation

The included SmartBracket mounting panel and metal swivel mount enable secure installation at the correct height and angle. The swivel mount allows the detector to be precisely aimed at the intended coverage zone after mounting, without the need to reposition the bracket. A built-in tamper switch notifies the system if the detector is displaced or removed from its mounting position.
