The present invention relates to a location tracking system and method, and more particularly, to a location tracking system and method that can provide image information as well as the location information of the target using CCTV and RFID technology.

RFID technology has developed a variety of techniques for tracking the location of moving objects, animals or people. The position tracking system according to the related art is composed of a transmitter for generating position information, a receiver for receiving position information transmitted from the transmitter, and a position guide device for receiving and guiding position information from the receiver. Such a location tracking system tracks the location of a target carrying a transmitter using a GPS device to obtain location information, but has a disadvantage in that the weight and volume of the transmitter are large. In addition, there is a problem in that a plurality of base stations must be separately installed for receiving location information transmitted from a transmitter. In addition, since the transmitter is driven by a battery, when the battery is exhausted, the position tracking function can no longer be performed.

Meanwhile, with the commercialization of RFID (Radio Frequency Identification) technology that can recognize unique information using radio waves, its application field is gradually increasing, and a system for performing location tracking using RFID technology is also being introduced. . RFID technology integrates the use of electromagnetic or electrostatic coupling within the radio frequency of the electromagnetic spectrum to identify objects, animals or humans. The biggest advantage of RFID is the need for direct contact or scanning in the visible band. There is no. RFID systems include antennas, readers, and tags, also called transponders. The antenna uses radio frequency propagation to carry a signal to activate the tag. When the tag is activated, it transmits the data it had to the antenna. The antenna is connected to the reader to receive data from the tag to perform data transmission using RFID. Here, the tag is divided into active and passive, and the active tag can transmit data even over a distance of several tens of meters from the reader, and the passive tag can transmit data only at a close distance of several centimeters.
