Description

Anti-theft system using signal transmitted by mobile phone network {ANTITHEFT SYSTEM WITH SIGNALS TRANSMITTED BY MOBILE PHONE NETWORK}

The present invention relates to an anti-theft system using a signal transmitted by a mobile phone network, in particular by a mobile phone network that transmits audio and video signals wirelessly to a mobile phone carried by a landlord located away from home with another mobile phone. An anti-theft system using a transmitted signal.

Until now, the anti-theft system consists of electronic sensors or mechanical sensors installed in windows and porches, and it is known that this sensor detects an object's vibration or movement to generate an alarm signal for an anti-theft effect.

Another type of anti-theft system employs a laser beam or a general photodetector that activates an alarm system to prevent theft when light is blocked. Laser beams or general photodetectors must be installed in pairs to achieve a better effect, which can cause wiring problems and higher density beam nets to reduce the number of photo-generating devices and photo detectors. Multiple reflection mirrors should be installed for multiple reflection paths to obtain. Since the cost of using a laser beam as a light source is very expensive, this method is applied only when stringent security is required.

Home anti-theft systems are usually connected to a central surveillance center or police station surveillance system, which must be connected together with cables and wires. This makes connection and transmission inconvenient, cumbersome, and expensive to wire.

In case of a robbery, only the central surveillance center or police station's surveillance system is immediately known and the landlord is not immediately aware. If there are visitors and the homeowner is not at home, the homeowner will not be aware of the robbery at all and the visitors will be confused and uncomfortable.

Another conventional technique is to transmit images and alarm signals using existing telephone networks for remote monitors and automatic alarm systems. However, transmission by telephone line may only be applied at certain points, such as police stations, security centers, or homeowners' offices. Only when there is a burglar invasion will the police and security centers send people to check for abnormal situations. Such a structure cannot realize bidirectional communication. The two-way monitoring system applies only when the landlord is in a place where the telephone line is connected, and it is not applicable where there is no telephone line, resulting in blind spots. Another disadvantage of telephone line systems is that the wires can be easily accidentally or deliberately damaged.

An object of the present invention is to provide an anti-theft system using a signal transmitted by a mobile telephone network and a mobile telephone network that transmits audio and video signals wirelessly.

Another object of the present invention is to provide an anti-theft system using a signal transmitted by a mobile telephone network that enables bidirectional transmission so that a user can directly control the system at a long distance.

It is yet another object of the present invention to provide an anti-theft system using a signal transmitted by a mobile telephone network which can install video cameras at multiple points to simultaneously monitor multiple points.
