1、Using flame‑retardant material, high temperature resistance, sturdy and durable, good shockproof function, fully enclosed shell, effective insect‑proof, dust‑proof and anti‑interference from the outside world. 2、Built‑in microprocessor with First Step Processing (FSP), 7.5m x 7.5m (24.6ft x 24.6ft) detection range. Intelligent analysis provides excellent detection performance to ensure work stability. 3、Used with a host (not included), when the human body enters the detection range of the detector, it will trigger the detector to send the signal to the networked host, and the host will send an alarm. 4、Used with a sound light alarm (not included), the sound light alarm is armed, when the infrared is triggered, the sound and light horn will emit a high decibel sound on the spot, and it will be accompanied by a red flashing prompt. 5、Use with a security camera (not included), and the camera need connect to the internet. After the infrared is triggered, the camera will call to notify, and you can immediately watch the alarm condition through the camera.
