WiMAX provides high bitrates wireless connectivity. This high bit rate wireless connection is potential to be used as the wireless camera surveillance infrastructure. However, real cases show that existing camera resolution does not help much when investigations go in detail. The captured images are often blurry when identifying someone ID. Therefore, more camera resolution is needed. However, problem emerged as higher camera resolution means higher bandwidth requirement. This paper proposed an event based video transmission to tackle bandwidth shortage. Video is sent only when special event occurred, such as fast movement or object detection. Otherwise, video is just recorded locally. The NS-2 simulator was employed to examine the idea. Low bit rate video was initially employed and sent together from surveillance cameras to server. The quality of video is then measured. The camera codec was then replaced by using higher coding rate video. As result, bandwidth drain occurred that produced high packet losses and poor video quality. The event based surveillance was the applied that enable at most 25% possibility that a video sent to server. As results, system is able to maintain high quality video received by the server.
