What is a PIR detector?

PIR detectors (passive infrared) are one of the most commonly used motion detectors in alarm systems. They detect changes in infrared radiation (heat) in the environment, allowing the alarm system to react when an intruder is detected in its field.

How does PIR technology work?

The Pyroelectric Sensor (crystal) inside the PIR sensor generates a slight voltage when its temperature changes — for example, when a human appears in the detection field. PIR detectors analyze signals in the respective optical zones (e.g. with Fresnel lens), which allows to filter out random interference. {index=0}

Advantages of using PIR detectors

• Low energy consumption: PIR detectors are energy-efficient, making them suitable for battery work. {index=1}
• Wide selection of configurations: Wall models, curtain models (e.g. for peripheral protection) and animal-resistant versions are available. {index=2}
• Simple integration with the alarm system: The PIR detectors can be connected to the control panel, GSM alarm or smart home system.
• Anti-masking and tamper functions: Advanced models can detect attempts to immobilize the detector (masking) or open the housing. {index=3}

What should I pay attention to when choosing a PIR detector?

• Angle and range of detection: Select an angle detector (e.g. standard, curtain) and range adapted to the protected area. {index=4}
• Resistance to false alarms: PIR detectors can generate alarms in places with sudden changes in temperature, drafts or near heat sources. {index=5}
• Communication type: Wireless versions (batteries) vs wired (power supply → higher reliability).
• Securities: Make sure the detector has a sabotage function (tamper) and, if necessary, protection against masking. {index=6}
• Installation: Mount the detector on the wall, away from direct sunlight and heat sources, so as not to cause false detection. {index=7}

Most common questions (FAQ)

Will PIR respond to a little dog?

This depends on the model — some PIR detectors have the function of "PET immunity" and ignore the movement of animals to a specific mass. {index=14}

Is PIR better than a dual detector (PIR + MW)?

PIR is simpler and cheaper, but in places exposed to false alarms (e.g. drafts, heat sources) dual detectors can be more reliable. :contentReference[oaicite:15]{index=15}

Where should I put the PIR sensor?

Mounting in the corner of the room on the wall provides optimum detection range. Avoid places directly opposite windows or heaters that can cause false detection. :contentReference[oaicite:16]{index=16}
