Abstract
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...
