Common intelligent security equipment in the existing market has door magnetic alarm, intelligent camera, human response alarm etc. mainly is located the theftproof, but can not carry out effective, accurate, timely warning, thereby all be easily found the interference that receives devices such as decoder in addition, the effect is not good.

The main anti-theft alarm devices existing in the current market:

1. door magnetism formula alarm: i.e. by sensing the change in position of the object by sensing the strength of the magnetic field. The door magnetic alarm generally consists of a switch and a magnet, and is required to be installed at a door gap, and when the door is opened, the magnetic force between the switch and the magnet disappears to trigger the alarm, so that the installation position of the door magnetic alarm is limited, the alarm is obviously installed and is easy to find, and the door magnetic alarm is easy to be interfered by the magnetic force to lose the alarm function;

2. the intelligent camera: the camera monitors the outside of the door, but when a lawbreaker appears under a monitoring video, the camera cannot give an alarm immediately, people need to pay attention to the video at any moment, the camera also has a monitoring dead angle and cannot completely monitor, and the camera only plays a monitoring role and cannot give an alarm in time to effectively prevent burglary;

3. the human body induction alarm is characterized in that after a lead of the human body touch induction alarm is hung on a metal door handle or a door lock, when a person touches the door handle lock or uses a master key lock to steal the door lock, the induction alarm can whistle to alarm, but the induction alarm is easy to be interfered so as to fail.

The networked intelligent door opening alarm with the recording device of application number 201620227255.6 performs door opening and theft prevention through detecting and identifying sound, but has large volume and inconvenient concealment, and after lawless persons find the alarm, the alarm loses the alarm effect through interference of a decoder and the like, and does not have anti-reconnaissance force; the alarm device is influenced by wireless signals, if the signals are poor, the alarm device may be abnormally used to generate false alarm, and when the voice of a person is hoarse, the situation is not easy to identify; therefore, the intelligent alarm device is not suitable for monitoring the access condition of important persons and is also not suitable for places with poor network signals.
