Detailed specifications and benefits
The Superior MotionProtect S is a PIR volumetric detector configured to monitor a broad, room-filling zone. It uses 24 PIR zones arranged across 6 planes to build a layered view of motion in its field of view. The detectors viewing angles are approximately 88.5 × 80 (horizontal × vertical), delivering coverage out to 12 m, with an option to limit range to 10 m to meet specific certification configurations.
SmartDetect signal processing and temperature compensation are designed to keep false alarms low across a range of indoor temperatures. The detector features three sensitivity levels, letting installers tune the sensor to the protected environments needs — higher sensitivity for low-traffic areas and reduced sensitivity where motion or environmental disturbances could trigger nuisance alerts.
One of the selling points of this model is pet immunity: when mounted and adjusted according to the installation manual, the detector commonly ignores animals up to ~20 kg and ~50 cm tall. Achieving reliable pet immunity depends on correct mounting height, angle and sensitivity setting, so professional installation and testing are important. For spaces with larger pets or unusual layouts, installers may opt for placement strategies or device settings that reduce false triggers without blind spots.
The Superior MotionProtect S communicates over the Jeweller protocol, an encrypted bidirectional radio system used across Ajax devices. For EU models this runs in the 868 MHz band, and vendor materials report open-space ranges in the order of 1.2 to 1.7 km depending on the version and environment. In practice, achievable range will depend on building materials, interference and placement.
Security features include AES-based encryption, jamming detection and tamper alerts (the device is secured to the SmartBracket with a screw). Two-way communication allows the hub to confirm device status and ensures more resilient signalling compared to one-way transmitters.
The detector is powered by a single CR123A battery (supplied pre-installed). Ajax quotes up to ~5 years of battery life under typical usage patterns; actual lifetime varies with reporting frequency, radio traffic and environmental conditions. The ABS enclosure measures approximately 110 × 65 × 50 mm and mounts on the SmartBracket plate, which includes a tamper-secure screw fastening. Some reseller listings report IP50 and IK04 ratings; check the datasheet and manual for precise environmental limitations.
The Superior line is marketed for professional/project distribution and, in some resellers listings, is associated with EN 50131 Grade 2 certification depending on configuration and regional requirements. Because certification and grade specifications can vary with project settings, installers should consult the official datasheet, local regulations and relevant standards (e.g., EN 50131) before specifying this detector for grade-rated systems.
Use cases and scenarios where the detector excels
The Superior MotionProtect S is aimed at professional installations where higher performance, configurability and secure radio communications are priorities. Typical use cases include:
- Residential properties with pets:Houses where occupants own medium-sized pets and need reliable intrusion detection without frequent false alarms.
- Multi-room homes and apartments:Long-range volumetric coverage helps reduce the number of sensors needed to protect larger rooms and hallways.
- Offices and small commercial spaces:Conference rooms, private offices and corridors where installer-grade features and encryption are required.
- Retail or light commercial premises:Shops and showrooms that need dependable motion detection with tamper protection and clear reporting.
- Integrator and project deployments:Larger builds where system designers require consistent radio range, remote management and compliance with project specifications.
Because it is a PIR-only detector, it excels in environments where well-placed optical detection is sufficient, and where installers can control mounting geometry and sensitivity. For areas with environmental disturbances (drafts, direct sunlight, HVAC blowers), careful placement and configuration will maximize performance.
How it compares with similar products
Compared with entry-level consumer PIR sensors, the Ajax Superior MotionProtect S offers longer detection range (up to 12 m), professional-grade mounting and tamper protection, and an encrypted two-way radio system designed for integration into managed alarm systems. These features make it better suited to project installations where system-wide interoperability, security and serviceability are important.
Within the Ajax family, the Superior line is aimed at installers and projects rather than direct retail consumers. Differences often include distributor-only activation policies, configuration options tailored to certification, and potentially different RF ranges or mechanical refinements. For customers evaluating MotionProtect vs Superior MotionProtect, the key considerations are project scale, certification requirements and the need for installer-controlled settings.
Dual-technology sensors (e.g., PIR combined with microwave) can reduce false alarms in certain environments because two independent detection methods must trigger. The Superior MotionProtect S uses advanced PIR processing (SmartDetect) and temperature compensation to limit false activations while keeping the device simpler, less power-hungry and typically less expensive than dual-tech alternatives. For many indoor spaces, a well-installed PIR with good signal processing provides reliable protection without the extra complexity of dual-tech sensors.
Customer feedback and installer impressions
Publicly available reseller notes and installer discussions commonly emphasize the following strengths: consistent detection across rooms, reliable Jeweller communications when line-of-sight is maintained or site planning is performed, effective pet immunity when installed per the manual, and convenient battery life with the CR123A cell. Installers also appreciate the tamper-secure SmartBracket and the configurability of sensitivity levels.
Potential limitations noted in the field include the usual caveats for PIR-only devices: sensitivity to mounting location, the need to avoid pointing directly at windows or HVAC outlets, and the dependence of radio range on site conditions. Because the Superior range is targeted at installer distribution, buyers should confirm activation requirements and warranty/partner policies with their supplier.
