Guide to Motion Sensors

What is a Sensor?

Sensors are basically devices that capture variations of certain quantities in the surrounding environment, transforming them into output, often in the form of electrical signals. They touch on different areas and are indispensable elements in numerous daily applications.

Variety of Sensors and Their Role

In addition to the wide range of sensors available, those dedicated to motion detection have a specific and crucial role, especially in the field of home security.

Operation of Motion Detection Sensors

How Volumetric Sensors Work

Motion sensors, also known as volumetric or radar sensors, are able to identify the presence of movement within a certain area. Their main use is found in security systems, where their ability to create invisible barriers becomes essential for the detection of unwanted intrusions.

• Strategic Installation: To maximize their effectiveness, it is advisable to place these devices in strategic places such as entrances, passages, stairs, doors and windows.
• Perimeter Sensors: Positioned outside the buildings, they activate different operating modes of the internal sensors such as "night" or "at home" mode.

Installation of Motion Sensors and Home Security

Accurate positioning of motion sensors ensures optimal defense for your home. The installation of perimeter sensors also offers further benefits to residents, allowing them to move freely within the home without triggering false alarms, while maintaining a high level of protection against break-in attempts.

Benefits of Using Motion Sensors

Protection and Comfort

Motion sensors offer a high degree of security without compromising the comfort of the inhabitants. Their advanced technology allows you to distinguish between friendly presences and potential threats, thus protecting your home environment efficiently and discreetly.

Theft Prevention with Volumetric Sensors

The integration of motion sensors within a security system represents an ideal solution to prevent unwanted intrusions and thefts, providing users with peace of mind and security.

Main Categories of Motion Detectors and Operation

There are different ways to classify presence detectors. The first distinction is based on their operating mechanism, while the second differentiation is based on the type of technology used for motion detection.

Motion Detectors: Functional Types

Regarding operation, we mainly encounter two distinct groups: traditional motion sensors and barrier sensors. The former belong to the category of volumetric detectors, adopted mainly for the surveillance of internal spaces. Barrier detectors, on the other hand, are designed for perimeter security, used to guard a facility's access points, such as doors and windows.

The Main Detection Technologies

• Passive Infrared Sensors (PIR) : These devices are activated as soon as they perceive a thermal change in the monitored area. The entry of a person into the monitored area generates a change in temperature which can activate the alarm. However, these sensors can be subject to false alarms, which occur without there having been an actual break-in.
• Dual Technology Sensors : To reduce erroneous alarms, more sophisticated sensors can be used that combine infrared technology with the Doppler detection system (DMT). The presence of detection bands, typically an upper and a lower beam, coupled to the thermal detector, offers greater safety and lowers the risk of false detections. To trigger the alarm, both beams must be interrupted simultaneously.
• Triple Technology Sensors : The most advanced detectors combine infrared and DMT systems with microwave technology. This can identify the presence of moving objects with the possibility of being set to recognize only bodies of specific sizes. This technology makes it possible to install these devices even in environments with pets, minimizing false alarms as much as possible and guaranteeing an extremely high level of reliability.

Conclusion on Motion Sensors

Choosing the appropriate motion sensor will depend on your specific security needs and the environment in which it will be installed. By considering the different operating methods and technologies used, it is possible to optimize protection and reduce the inconveniences linked to false alarms.

Installation Guide for Motion Sensors for Home Security

Why ask for help from a professional installer

Entrusting the installation of motion sensors to a qualified technician is a wise choice when it comes to increasing the security of your home. A professional in this field will evaluate with a detailed analysis where it is most advantageous to place the sensors for optimal protection. The work of an expert will guarantee coverage of every corner of the house, advising on the ideal number of devices to use.

Different types of Motion Sensors: Features and Advantages

The products currently available on the market for motion detection range between various models, from classic to more modern designs, accessible to all budgets. Wireless systems, in particular, are gaining popularity. By taking advantage of wireless technology, they allow greater safety to be guaranteed without the need to damage pre-existing electrical circuits.

The importance of integrating Motion Sensors into the Security System

Motion sensors are a crucial aspect in creating an effective home security system. Their reliability is significantly strengthened by recent technological innovations, making homes real strongholds.

Example of Complete Security System with Motion Sensors

• Outdoor motion sensors: to sense the presence of intruders before they can get close to the house's entrances.
• Curtain sensors for windows and doors: ideal for monitoring windows and doors, detecting intrusion attempts by crossing them.
• Internal motion sensors: to reveal any suspicious activity inside the home, completing the perimeter defense.

This arrangement of sensors turns home invasion into a highly complicated operation for would-be attackers, raising the level of protection of the home.
