Further, the installation height of the transmitter 2 and the receiver 3 from the indoor ground is smaller than the height of the top edge of the entrance door 1 from the indoor ground, the distance between the transmitting end of the transmitter 2 and the receiving end of the receiver 3 from the ground is 1.9 m in the embodiment, on one hand, the purpose of the setting is that when the entrance door 1 is opened and closed, the entrance door 1 can reliably shield the infrared light beam emitted by the transmitter 2, on the other hand, the transmitter 2 is relatively higher, and the influence on the sight line of people can not be generated when the entrance door 1 is opened and closed.
Furthermore, the wavelength of the infrared beam emitted by the transmitter 2 is 0.95 μm, and the infrared beam with the wavelength of 0.95 μm does not generate the red exposure phenomenon, so that the concealment performance is good; the horizontal shortest distance between the infrared beam emitted by the transmitter 2 and the entrance door 1 is 15cm, and the entrance door 1 can be sensed by the active infrared detector only by opening a gap.
Further, the electronic tag 5 in this embodiment is a passive electronic tag, so that the volume of the electronic tag 5 becomes small, and the electronic tag 5 is easily embedded in the card 14, which is convenient for an operator to carry.
The working process of the anti-theft system is as follows:
under the condition that someone is in the room at ordinary times or the theft is not needed, only the camera 6 works in the theft prevention system, the camera 6 monitors the room in real time, the mode is recording and storing, the storage time can be set according to the requirement, the video content stored in the camera 6 can be automatically cleared after the storage time is up, and the stored video can not be sent to a mobile phone or a computer of a room owner.
When the house owner needs to go out or someone in the house but needs to lock the entrance door 1:
the anti-theft system can be controlled to operate by a room owner carrying the electronic tag 5 with him through a mobile phone, at the moment, the active infrared detector, the RFID system and the camera 6 are all in working states, the room owner can check indoor conditions outdoors through the mobile phone or a computer in real time, and at the moment, the camera 6 can set the room owner to be in a working state of shooting while recording or in a working state of only shooting.
When a person opens the entrance door 1, the active infrared detector detects signal changes and provides the signal changes to the main control system, the main control system controls the camera 6 to enable the camera 6 to start recording in an early warning state, videos shot by the camera 6 are stored in real time and are sent to a mobile phone or a computer of a room owner, the time of the early warning state can be set to 10 seconds, when an operator enters the room in the time period, as the reader 4 is arranged close to the entrance door 1, if the operator carries the electronic tag 5 with the operator, the RFID system transmits signals to the main control system after identifying the electronic tag 5 on the operator, the main control system immediately releases the recording in the early warning state, and the main control system is noticed that although the early warning state of the system is released, the videos shot by the camera 6 before are still sent to the room owner, and the purpose of the setting is that, the electronic tag 5 of the chamber owner is prevented from being stolen or copied by a person, and the electronic tag is convenient to check and trace in the later period in case of a theft event; on the contrary, if the active infrared detector detects the signal change, but the RFID system does not recognize the electronic tag 5 matched with the active infrared detector within the time period set in the early warning state, the alarm module 11 in the main control system starts to perform ring alarm, and the camera 6 maintains the real-time recorded working state and transmits the video information to the cell phone or the computer of the room owner in real time while performing ring alarm.
Regardless of the ring alert for any reason, the homeowner may dismiss the alert by a cell phone or computer.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
