Combined motion and glass break detector CombiProtect Jeweller

Burglar alarm detectors were installed mainly in shops, shopping centres, public places, and industrial enterprises until recently. Today, living quarters have been added to the list above.

Motion sensors detect objects that move and react to them, giving users control of the space. A device for fixing the movement of objects allows users to control the situation in a guarded space.

After activating the motion detector, several automated actions are triggered, which depend on the settings:

• various devices are turned on;
• doors open;
• the light turns on;
• an alarm is triggered.

When choosing a motion sensor, it is vital to understand its types, differences and possible applications.

According to the principle of operation, motion sensors are divided into several types:

• Ultrasonic motion sensors — emit high-frequency waves that bounce off the surfaces of nearby objects and return to the sensors. Until the perimeter is violated, the picture remains unchanged. The sensor gives a signal as soon as it detects changes.
• Infrared motion sensors — react to thermal radiation. Sensitive PIR sensors capture heat waves that pass through Fresnel lenses. When an object with infrared radiation enters the device's field of action, the motion sensors send a signal to perform the programmed action.
• Photoelectric motion sensors — react to changes in the light flux. Such detectors consist of two separate parts. One emits a bright beam, and the second catches it. In addition to the visible spectrum, devices often use invisible IR. When an object blocks the light beam, the motion sensor is triggered.
• Motion sensors that operate in the radio wave range are tomographic and microwave. Radio waves pass freely through walls and wooden furniture, allowing perimeter control, regardless of the layout.

Motion sensors are used only in combination with other devices and electrical appliances, complex, multicomponent systems.

Using motion detectors

Motion detectors are connected to other devices because they only detect changes in the territory under protection and send a signal. The connected systems react in the right way. Before choosing a detector, the user needs to understand the most common uses of motion sensors and choose a device according to their needs.

Sensors for security alarms

The primary function of motion sensors for security is a reaction to the movement of objects. With their help, it is possible to prevent intrusion into the protected area and damage to property.

Security systems are used not only in large industrial buildings and commercial enterprises. Devices of this kind are widely used to ensure the security of banks, museums, etc. Motion sensors are installed in private premises, connected to video cameras and alarms, and displayed on the control panel of a security organisation if the user wishes.

Motion sensors for smart home

The advantage of using motion sensors in the alarm system lies in several device features:

• They turn on the light when a person enters the room or signals.
• Turn off the light if the user leaves the source on.

A light sensor in the cabinet

Motion detectors are often used for kitchen cabinets, interior lighting, and mezzanines. In the dressing room, wardrobe or shelving, manufacturers increasingly install motion detectors that turn on the light.

Motion detector for animals

The motion detectors and spotlights, installed in the feeding area, allow the pet to eat in comfortable lighting. And the owners definitely will not step on a fluffy tail in the dark.

Motion sensors are installed in tandem with other types of detectors. One of the most common is a glass break sensor for an alarm.

Glass break detector

Glass break detectors are one type of burglar alarm detector. The sensor aims to respond to the sound of breaking the glass sheet. Such sensors are used as an additional means of detecting intrusion into a protected area.

Glass break detectors are tuned to respond to the sound when glass is broken. This sound can manifest itself in different ways: the first sound is a blow to the glass sheet, and the second sound arises from the deflection of the glass from the struck object. This is followed by the sound of fragments ringing. With the help of a sensitive microphone on the sensor board, all sounds are picked up and processed by an electronic circuit, "which decides" on the alarm signal.

The glass break detector should be installed on the ceiling or a wall at a certain distance from the window or on the wall of the protected premises. To verify the correct installation and configuration, the user needs to test the sensor using devices that imitate the sound of breaking glass.

For maximum reliability, the glass break sensor is combined with other detectors. Motion detectors and reed switches on windows and doors use a glass break sensor for reliable protection. Or, there are combined motion and break sensors. 

Combined motion and break detector CombiProtect Jeweller

The CombiProtect Jeweller wireless motion and glass break detector detect human movement and glass breaking in a protected area.

The principle of operation of the wireless sensor for the Ajax CombiProtect Jeweller alarm

The CombiProtect Jeweller wireless detector combines the functions of two detectors — glass break and motion. The device captures human movement in a protected area at a distance of up to 12 metres and determines the breaking of a glass at a distance of up to 9 metres.

The principle of operation of a wireless motion and glass break sensor is based on detecting infrared radiation from living beings. When a security sensor detects such radiation, it analyses the object's weight, and if it is above 20 kg, it sends an alarm signal to the central security alarm unit. The algorithm for processing the received signal provides a thorough check of the object in terms of mass and movement, which reduces the risk of false alarms from animals.

Using this principle of operation, the CombiProtect Jeweller motion and glass break detector are triggered only when a person's movement is detected. The detector does not respond to the movement of inanimate objects. If clothes fall from the hanger in the room or a draft opens the door, the sensor will not be activated.

Thanks to a particular microphone, the glass break and motion sensor detect and record specific low and high-frequency sounds from glass breaking. If a glass sheet is broken in a protected area, the detector picks up these sounds and sends an alarm signal via radio to the central alarm unit. The wireless security sensor reacts exclusively to the sound of broken glass, ignoring other loud sounds using a unique multi-stage analysis.

The wireless detectors works based on a wireless radio communication system that uses anti-forgery and message encryption. Thus, the alarm system is protected from attempts to enter the protected area. The wireless combined sensor also has a state-of-the-art, highly reliable communication system that allows it to operate within multiple floors of a building or up to 2,000 metres away from a central alarm unit in the absence of obstructions.

The CombiProtect Jeweller wireless motion and glass break detector can protect any objects: private houses, apartments, cottages, shops, offices, warehouses, industrial premises, etc. Convenient and easy sensor installation on an intelligent mount without disassembling the case is one of the advantages.

Features of the Ajax motion and glass break detector

• Easy installation and configuration of the wireless motion and glass break detector.
• Mounting the sensor on the SmartBracket mount will not damage the repair and does not require the disassembly of the device case.
• A tamper protects the motion's body and prevents the sensor from opening.
• The wireless sensor continuously transmits test signals to the alarm control panel. The polling period of the detectors can be adjusted at your discretion. If you try to steal or break the sensor, the intelligent security system will immediately know about it and send an alarm.
• Thanks to a special energy-saving algorithm, the detector operates from a pre-installed battery for up to 5 years.
• To control the operation of the alarm, the wireless motion detector regularly transmits a low battery signal to the control panel. The user will be promptly notified of the need to replace the battery in the sensor.
• The information transmitted by the motion and breakage sensor is protected from attempts of substitution and interception.
• The wireless motion and breakage detector work with the Ajax ocBridge wireless signal receiver.
