About this deal

Many false alarms will be caused by the placement of the alarm and sensors rather than the cost or quality of the alarm. This means that when installing wireless motion detector alarms, you should arrange them in places that maximise their efficiency while minimising false warnings. Sensors are also often designed to "ignore" domestic pets, such as dogs or cats, by setting a higher sensitivity threshold, or by ensuring that the floor of the room remains out of focus. item specification -- distance: 2~12 meters (adjustable); detection angle: ≤160°; time-delay: 5sec~10min(adjustable); recommended installation height: 1.5~4m. wire connection instruction: brown wire: live input, red wire: live output, blue wire: common neutral.

PIR sensors are great at determining if you have an intruder or it’s just an animal, for example. They have a better accuracy level and can reduce false alarms overall. However, you should pay attention to some small details to further reduce the risk of false alarms from your PIR motion sensors. PIR sensor-based alarms can be designed to ignore certain shapes of moving objects, or only detect motion above a certain height. This makes them suitable for households that have pets, allowing you to set the alarm before leaving the house in the day without worrying that it will be triggered by your cat or dog moving about. PIR (passive infrared) sensors utilise the detection of infrared that is radiated from all objects that emit heat. This type of emission is not visible to the human eye, but sensors that operate using infrared wavelengths can detect such activity. They are sometimes referred to as ‘motion-based detectors’, as they sense the presence of people, animals and objects through the movement of their infrared wavelengths. It is also recommended that the PIR not be placed in such a position that an HVAC vent would blow hot or cold air onto the surface of the plastic which covers the housing's window. Although air has very low emissivity (emits very small amounts of infrared energy), the air blowing on the plastic window cover could change the plastic's temperature enough to trigger a false alarm.Motion detector with superimposed beam pattern. The length of the beams is a measure of the detectors sensitivity in that direction. Once the PIR sensor detects movement an alert is sent to the alarm panel which activates the alarm. It is critical to completely enclose the PIR sensor itself with a material that can reduce the effects of external temperature and humidity, such as metals like silicon. The benefits of PIR motion sensor outdoor -- the pir sensor adopts infrared body motion induction technology, which can achieve intelligent control and energy saving. recommended that the product is installed by professional electrician. Manufacturers recommend careful placement of their products to prevent false alarms (i.e., any detection not caused by an intruder). One of the most successful to date is the PIR sensor method found in many of the burglar alarm systems installed in domestic and commercial properties alike. But what is a PIR Sensor? And what makes them so effective? What is a PIR Sensor?

PIRs come in many configurations for a wide variety of applications. The most common models have numerous Fresnel lenses or mirror segments, an effective range of about 10 meters (30 feet), and a field of view less than 180°. Models with wider fields of view, including 360°, are available, typically designed to mount on a ceiling. Some larger PIRs are made with single segment mirrors and can sense changes in infrared energy over 30 meters (100 feet) from the PIR. There are also PIRs designed with reversible orientation mirrors which allow either broad coverage (110° wide) or very narrow "curtain" coverage, or with individually selectable segments to "shape" the coverage. Designs have been implemented in which a PIR circuit measures the temperature of a remote object. [6] In such a circuit, a non-differential PIR output is used. The output signal is evaluated according to a calibration for the IR spectrum of a specific type of matter to be observed. By this means, relatively accurate and precise temperature measurements may be obtained remotely. Without calibration to the type of material being observed, a PIR thermometer device is able to measure changes in IR emission which correspond directly to temperature changes, but the actual temperature values cannot be calculated. Simple things like air blowing in close proximity or a rodent moving across the floor can still set off your alarm. Additional uses can be in public toilets, walk-in pantries, hallways or anywhere that automatic control of lights is useful. This can provide energy savings as the lights are only turned on when they are needed and there is no reliance on users remembering to turn the lights off when they leave the area.

Pet-Friendly PIR Sensors

A PIR-based motion detector is used to sense movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically activated lighting systems.
