What is the difference between PIR and motion sensor?
What is the difference between PIR and motion sensor?
PIR or Passive Infrared motion sensors are designed to reliably detect people, large pets & other large warm moving objects. True Detect™ is more than just motion sensing but also includes thermal heat sensing. The True Detect PIR sensor is triggered when a security camera senses heat whether from people or cars.
Can PIR sensors be used outdoors?
This Aeotec Z-Wave Multi-Sensor can be used outside and can also detect light, temperature and humidity. When IR motion sensors are used outdoors, they are more likely to cause false alarms. The most common cause of a false trip is rapidly changing weather conditions. If the beam is broken, it trips the alarm system.
What is an outdoor PIR?
Outdoor PIR and Motion Detection Sensors They are triggered by moving heat sources and can be highly effective at deterring intruders. We also provide dusk-till-dawn outdoor sensors that automatically switch on when the sunlight starts to fade and remain on until the sun comes up.
Can PIR sensor detect through walls?
They can detect motion over large areas entirely because they can sense through walls and other obstructions.
Do PIR motion sensors work through glass?
The motion sensor is based on passive infrared detection, therefore it works through clear glass.
What does PIR stand for in cameras?
Passive Infrared
The PIR (Passive Infrared) motion sensors are designed for security & optimised to reliably detect people, large pets & other large warm moving objects. This means – security cameras smart enough to detect humans rather than sheets blowing in the wind.
Are PIR sensors affected by heat?
Over most of the temperature range, a PIR sensor works consistently in detecting the temperature difference, with no trouble. At high temperatures, close to body temperature at about 99 degrees F, there is a small range of outside temperatures where a PIR sensor range will reduce.
What can trigger a PIR sensor?
The first cause of PIR false alarms is low or unstable voltage at the detector.
What does PIR stand for?
passive infra-red
PIR stands for passive infra-red. PIR sensors are commonly used in security systems – both for triggering alarms and/or lighting. How does a PIR alarm work? All objects emit a certain level of infrared radiation. A PIR sensor inside an alarm measures the amount of this infrared activity.
What is the best outdoor motion sensor?
Best motion detector lights reviews

Do PIR sensors work in the dark?
The short answer is yes. Motion sensors do work in complete darkness, as none of the motion sensors mentioned above are reliant on using images to detect motion. Instead of images, PIR motion sensors detect changes in the level of received infrared. Likewise, ultrasonic motion sensors also do not require images.
Can PIR sensor detect speed?
If the PIR sensor notices the infrared energy, the motion detector is triggered and the sensor outputs HIGH on its SIG pin. The detecting range and response speed can be adjusted by 2 potentiometers soldered on its circuit board, The response speed is from 0.3s – 25s, and max 6 meters of detecting range.
How big of an area does a Pir detector cover?
120 degree wide and 12 m (40 ft.) detection area. Either high or low mount are selectable. A robust, weatherproof and specifically designed Outdoor PIR for short-range outdoor applications.

What can an outdoor Pir be used for?
Use the included masking strips to create a specific detection pattern, if desired. In this way, the 40 X 50 Outdoor PIR w/Double Conductive Shield can be used as a pet immune motion detector or can capture motion only in specific spots. Sensitivity can also be set at high, medium, or low.
