Infrared correlation technology based intrusion detection device

Abstract

The invention provides an infrared correlation technology based intrusion detection device. The infrared correlation technology based intrusion detection device comprises an infrared transmitter and an infrared receiver. The infrared correlation technology based intrusion detection device is characterized by also comprising an LED (Light Emitting Diode) lighting device and a camera device which are connected with the infrared receiver; the LED lighting device comprises an LED lamp control circuit, an LED driving circuit and an LED lamp which is connected with the LED driving circuit; the LED lamp control circuit is trigged by an alarm signal and the LED driving circuit is driven to start the LED lamp; the camera device comprises a camera host and a camera; the camera device is triggered by the alarm signal to perform shooting and enters into the standby state after the alarm trigger signal is interrupted. According to the infrared correlation technology based intrusion detection device, a multiple function integrated security product is provided for a user, intruders can be deterred by multiple warning methods indeed, and accordingly crimes can be reduced.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an intrusion detection device based on infrared cross-radiation technology. Background technique [0002] As early as the early 1990s, infrared technology was widely used and entered the security field, and then there were active infrared intrusion detectors (infrared direct-fire) products. The infrared intrusion detector generally includes an infrared transmitter and an infrared receiver, and its working principle is: when the infrared light beam between the infrared transmitter and the receiver is blocked by an intruder, the infrared intrusion detector generates an alarm signal, and The alarm signal triggers a speaker warning or an indicator lamp warning. The shortcoming of prior art is: adopt single sound alarm mode, can't really cause threat deterrence effect to intruder (here generally refers to stealing, stealing perpetrator), scares it away. On the contrary, when the s...

Problems solved by technology

The shortcoming of prior art is: adopt single sound alarm mode, can't really cause threat deterrence effect to intruder (here generally refers to stealing, stealing perpetrator), frighten it away

On the contrary, when the security personnel learn of the danger and rush to the intrusion site, they will inevitably confront the prepared intruders and even have violent conflicts, often causing harm to the security personnel themselves

[0003] The relatively single function of the above-mentioned infrared intrusion detectors is far from adapting to the ever-changing security needs, and the market urgently needs safer, more reliable, and multi-functional security products
