Ajax CombiProtect: Ajax Wireless Motion Sensor and Glass Breakage Detection System

Single device – Double protection
We have combined two sensor functions into a single device and created a comprehensive security solution for a wide variety of spaces – CombiProtect Jeweller . This device integrates two main functions: motion detection and It detects the sound of breaking glass . The sensors can be remotely configured via the app, including sensitivity adjustment. Users can also check the device's operation directly on the app. The intuitive interface and simple installation provide a satisfying experience for both technicians and end users.

High-quality PIR sensor

All Ajax motion sensors use PIR sensors. Excelitas Technologies (USA) Manufactured by Ajax – one of the leading optoelectronic component manufacturers since 1931. Ajax inspects 100% of its products during manufacturing, ensuring superior quality. When integrated into Ajax technology, this sensor delivers maximum accuracy in intrusion detection.

Special lenses

The Fresnel lens's regions are designed to clearly distinguish infrared images of humans, pets, and thermal noise. Larger regions focus on the head and torso of an adult, while smaller regions produce a more detailed histogram. This lens provides accurate information about thermal objects within the monitored area and their movement characteristics.

Intelligent thermal noise filter

We analyzed thousands of thermal samples from people, pets, and the environment to develop the algorithm. SmartDetect . In protection mode, the device continuously analyzes the thermal profile from the PIR sensor – including IR radiation intensity, heat spot size, movement speed, time spent in the detection zone, and many other factors. This algorithm helps identify and eliminate false alarms with high accuracy, ensuring the device only reacts when there is real human movement.

Temperature compensation according to the environment

Software-based temperature compensation helps maintain the contrast of the thermal profile, even when the ambient temperature is close to human body temperature. With each ambient temperature measurement, the device adjusts the data from the PIR sensor based on a stored coefficient table. This ensures accurate operation across the entire operating temperature range.

Customize sensitivity

CombiProtect can be adjusted to suit specific environments, including the presence of pets or multiple sources of heat interference. Lower sensitivity levels mean less likely to react to active pets. Higher sensitivity levels ensure an alarm is triggered by any movement within the detection area.

Professional installation

Proper installation at the correct height. 2.4 m And aligning the lens perpendicular to the predicted intruder's path will help create an accurate heat map and potentially bypass pets. The device can avoid false alarms with pets of considerable weight. up to 20 kg and height under 50 cm .

Improved broken glass detection

CombiProtect Jeweller uses high-sensitivity electronic microphone same numerical algorithm DualTone To detect the sound of breaking glass. The device will only sound an alarm when it detects two sounds simultaneously within a certain range. 1.5 seconds :

1. The low-pitched sound (low frequency) of the impact.

2. The echo (high frequency) of breaking glass.
   This two-stage detection mechanism minimizes the risk of false alarms. Three different sensitivity levels can be configured in the Ajax application, suitable for any installation environment.

Wireless, flexible, and efficient.

The equipment is fully operational. No wires needed , optimized for flexible installation. A CR123A battery is pre-installed from a reputable manufacturer, ensuring the device's functionality. Ready to use immediately , no further setup required. Ajax tests each battery and device during manufacturing to ensure performance and accuracy.

• The lifespan is up to 5 years.

• Low battery warnings are sent monthly. to allow users to replace it in a timely manner.

• The battery is easily replaceable. And the status is always updated in the app.

Real-time system self-monitoring

All Ajax devices have a mechanism. Self-check and status reporting The data is sent to the control center. Important parameters such as tamper status, connectivity, power supply, and sensors are continuously monitored. The server Ajax Cloud Control the connection between the hub and the Ajax application, ensuring notifications. instant This information is provided to the user, security company, or incident response center. If a technical fault occurs, the responsible engineer will be notified immediately.

• Automatically diagnose the device and send status reports.

• The app periodically updates the device status.

• Timely and prompt maintenance notifications.
