CCTV MANAGEMENT SYSTEM SUPPORTING EXTENDED DATA TRANSMISSION COVERAGE THROUGH WIRELESS LAN
First Claim
1. A closed-circuit television (CCTV) management system in which a plurality of wireless LAN transmission type CCTVs are installed in preset positions so that photographed data thereof are received and are collectively managed, the CCTV management system comprising:
- a plurality of CCTVs installed within coverage of an object to be photographed and managed and including wireless LAN modules to wirelessly transmit and receive photographed data;
an access point receiving the photographed data from the CCTVs;
a packet demultiplexer receiving the photographed data from the access point to generate compressed image data obtained by removing header data from the photographed data;
an image decoder receiving the compressed image data from the packet demultiplexer to decode the compressed image data; and
a display receiving the decoded image data from the image decoder to output the decoded image data;
wherein the plurality of CCTVs sequentially transmit the photographed data in an order set in accordance with a distance and mix the photographed data received during transmission with data photographed by a corresponding CCTV to transmit mixed data.

Abstract
Disclosed is a management system of an area to be photographed using a plurality of CCTVs, and more particularly to, a CCTV management system supporting an extended data transmission coverage with a wireless LAN, in which a plurality of CCTVs are installed in an area to be photographed and are collectively managed, that can be installed easier than a wired CCTV management system and can remove a limit to the data transmission coverage of a wireless CCTV management system by sequentially transmitting data photographed by the CCTVs in accordance with the access order of distances so that data photographed by a CCTV and data photographed by the other CCTVs are encoded and transmitted.
