Model No.: EF-PIR04
This PIR Motion Sensor is a special three-tech (PIR+PIR+MW) complex detector for outdoor intrusion. Signals of 3 sensors are with super stability and depend-ability by its advanced multi-grades digital signal processing technology. And they can offer 3 different detection modes on 2 sensitive grades in order to choose the best the detection way for spot environment and gets the best rate between the best detection ability and the minimum false alarm rate. With normal “AND”and “OR” modes, also with “EI” mode to avoid the damage of dopes spraying on the lens. Its unique water-proof design is totally fit for outdoor installation. At the same time, also with other functions such as anti-masking automatic setting and alarm type memory etc.

Used in conjunction with the wired alarm host, the C-type relay switch outputs the alarm signal.
The two-level sensitivity can be adjusted to select the detection method more suitable for the protection site, so as to obtain a good ratio between large detection capacity and small false alarm indication.
Microwaves have the ability to penetrate building walls:
As a kind of electromagnetic wave, microwave also has wave-particle duality. The basic properties of microwaves usually show three characteristics of penetration, reflection and absorption; for glass, plastic and porcelain, microwaves are almost penetrated without being absorbed. For water and food, it absorbs microwaves and heats itself; for metals, it reflects microwaves.
Suitable for apartments, villas, teaching buildings, office buildings, warehouses, factories, banks and other places.
