數位化的影音串流在網際網路上傳輸，雖然沒有如類比訊號受環境影響而模糊不清的問題，卻有不保證點對點頻寬的網際網路所造成的問題。
數位影音監控對於關鍵影像需要較高的畫質，但是數位影音在網際網路傳輸容易遺失封包、畫面會產生模糊不清甚至遺失現象，導致網際網路影音監控無法有效的應用。
基於在遠距監控的實用，本研究將開發一套監控專用串流伺服器，可在區域網路(LAN)或廣域網路(WAN)的環境下有效的監控及錄影。

Multimedia Streaming on the Internet without analog blurred problem, but there is no guarantee End-to-End internet bandwidth problems.
Digital video surveillance want high-definition video, but digital video transmission over the Internet easily lost packets, the video will produce blurred or even lost, and that leads the internet surveillance application unpractical.
Practical based on remote surveillance, this research will develop a dedicated streaming server for local area network (LAN) or wide area network (WAN) environments, and effective monitoring and recording.
