Invasion alarm system

Abstract

The invention provides an invasion alarm system and relates to a home anti-theft alarm system. The system comprises an anti-theft alarm controller and at least one intrusion detector, wherein the anti-theft alarm controller is connected with the intrusion detector. The home anti-theft alarm system is characterized in that: the intrusion detector has a function of direction identification; the invasion detector is used for detecting that a human body sends human body movement direction information to the anti-theft alarm controller when moving; and the anti-theft alarm controller is used for receiving the human body movement direction information sent by the invasion detector and determining unidirectional alarm or bidirectional alarm according to a protection state, and the alarm comprises alarm directions if the unidirectional alarm exists. The home anti-theft alarm system has the advantages that: detectors assembled on all doors and windows can be replaced by a small number of detectors, assembly positions are less interfered by external factors, and the false alarms of the detectors are reduced to a great extent.

Description

technical field [0001] The invention relates to an anti-theft alarm system, in particular to a home anti-theft alarm system. Background technique [0002] The most typical home burglar alarm solution at present is: install a wide-angle motion detector in the hall to detect intruders entering the hall, such as a wide-angle passive infrared detector; the horizontal detection angle of this wide-angle motion detector usually reaches more than 90 degrees. In the corner, its detection area can basically cover the entire hall; but this solution has the following problems: after the alarm system enters the state of arming at home (arming after falling asleep), due to the possibility of family members walking in the hall at night (such as going to the bathroom, etc.) , so the hall cannot be on alert, which means that the wide-angle motion detector cannot effectively guard the hall at night. [0003] In response to this situation, in recent years, motion detectors with narrow detecti...

[0002] The most typical home burglar alarm solution at present is: install a wide-angle motion detector in the hall to detect intruders entering the hall, such as a wide-angle passive infrared detector; the horizontal detection angle of this wide-angle motion detector usually reaches more than 90 degrees, and the installation In the corner, its detection area can basically cover the entire hall; but this scheme has the following problems: after the alarm system enters the state of arming at home (arming after falling asleep), due to the possibility of family members walking in the hall at night (such as going to the bathroom, etc.) , so the hall cannot be on alert, that is to say, the wide-angle motion detector cannot effectively guard against the hall at night

However, this detector also has the following problems: since the detection area is relatively close to the doors and windows, when the doors and windows are opened, the curtains blown by the wind may trigger the detector to alarm

That is to say, although this kind of detector with a narrow detection area solves the problem of artificial false alarms caused by the movement of family members at night, it cannot avoid the false alarms caused by environmental factors caused by fluttering curtains.

And when there are many doors and windows, the number of detectors used increases, which increases the cost of equipment
