The present invention relates to a real-time location tracking service monitoring system and method for transmitting a video that can enhance security by monitoring real-time visitor location information through a visitor tag.

The general access management system not only prevents unauthorized access in the work and schedule places that restrict access, but also protects important facilities and information from external intrusion or destruction. The access control system uses a key pattern, a key method using a magnet, and a keypad method, which are formed in a predetermined pattern, but recently, as the interest in the importance of security for major facilities or information has been improved, security reliability may be required. In addition, there is a demand for the convenience of the user and the simplification of the authentication process.

In order to reflect these security requirements, the access management system uses card keys using magnetic cards and integrated circuit cards (ICC), or fingerprint recognition, iris recognition, vein recognition of the back of the hand, and voice recognition. Keys using biometrics have been developed.

However, the conventional access control system is a system for managing the access of other persons except those who have been granted access, and is not an access control system for managing the visitor's access, but a contact device such as a camera or an interphone to confirm the visitor. There is a problem that must be provided separately, as well as the access management staff to manage the visitor's access. In particular, the access control system as described above has a problem that the access of the outsider can not be managed when the password, card key, etc. to allow the access to be lost.

In order to improve the problems of the conventional access control method, a method of utilizing an RFID system for access control has been proposed. RFID / USN (RF IDentification / Ubiquitous Sensor Network), along with BcN and WiBro, has been recognized as an information and communication infrastructure leading the change to the future ubiquitous society. Application scope is spreading to the area of information management for high-speed moving objects as well as access management for various facilities.

However, the RFID-based access control system and its method can perform access management without the need for RFID tag holders to place the RFID tag on the RFID receiver, but it is mainly used to manage the access of the vehicle at the gate. There is a problem in that it does not satisfy the proper guidance on the restricted access or approval area of the non-approved area, and it is impossible to make a copper profit on which area the visitor is located and where they visited.

The access control system and method of Korean Patent Laid-Open Publication No. 2009-0034058 and an RFID detection unit for generating an RFID detection signal according to the detection of the reception of the tag information transmitted from the RFID tag worn by the accessor, generated in the human body of the accessor Infrared sensor detection unit for generating an infrared detection signal according to the detection of the infrared signal reception, and the permission determined by comparing the coefficients of the RFID detection signal and the infrared detection signal transmitted from each of the RFID detection unit and the infrared sensor detection unit Characterized in that it comprises an access authentication control unit for authenticating the access of the person according to whether or not the intruder of the access.

The access management system and its method are expected to enhance the security of the entrance by preventing the following access that allows unauthorized access to the open door, but the guidance for the entrance is insufficient in many areas of the building. In addition, there is a problem in that it is impossible to determine the traffic line where the authorized visitor is located and where.
