Project Title By : Modification of Webcam Camera to Internet Closed-Circuit Television : Mr. Sittisak Phumhirun Mr. Panu Rungsawang Project Advisors : Ms. Supitcha Cheevapruk Ms. Thitima Asavapromthada Major Field : Information and Production Technology Management Department : Information and Production Technology Management Academic Year : 2009 Abstract Nowadays closed circuit televisions that are popularly used costs very high. Some of them have no capacity to let users read through the internet system. If the users prefer to read the previous incidents, there is restriction. As a result, this study was aimed to modify a Webcam camera to function as a closed circuit television linked with the internet system that could be used effectively based on its details or aspects in an appropriate area. A Visual Basic program was designed and developed to be connected to the camera with the connection of the ports between a various networks for the users to read both real-time incidents and those previous one on demand. The administration section was responsible for the users application. The result of this study showed that the developed camera had the capacity to record the incidents though the internet system very clearly in the room with the dimension of 10x10 meters. Moreover, the users could read the previous incidents effectively as needed.

Project Title By : Modification of Webcam Camera to Internet Closed-Circuit Television : Mr. Sittisak Phumhirun Mr. Panu Rungsawang Project Advisors : Ms. Supitcha Cheevapruk Ms. Thitima Asavapromthada Major Field : Information and Production Technology Management Department : Information and Production Technology Management Academic Year : 2009 Abstract Nowadays closed circuit televisions that are popularly used costs very high. Some of them have no capacity to let users read through the internet system. If the users prefer to read the previous incidents, there is restriction. As a result, this study was aimed to modify a Webcam camera to function as a closed circuit television linked with the internet system that could be used effectively based on its details or aspects in an appropriate area. A Visual Basic program was designed and developed to be connected to the camera with the connection of the ports between a various networks for the users to read both real-time incidents and those previous one on demand. The administration section was responsible for the users application. The result of this study showed that the developed camera had the capacity to record the incidents though the internet system very clearly in the room with the dimension of 10x10 meters. Moreover, the users could read the previous incidents effectively as needed.
