Digital Audio Balun
It could be easily used on keystone jack panel or faceplate of the keystone series that has been designed.
The CCTV Video Balun allows baseband composite signal to be transmitted via a single unshielded twisted pair (UTP) cable for more versatile cabling.
The CCTV Balun is used in pairs to allow you to eliminate more expensive coaxial cable, including coupling signals from remote video cameras to display systems, video retrieve, security and surveillance monitoring applications.
The use of existing twisted pair infrastructure such as telephone cable and Cat.5 computer networking cables are also available. All our baluns are 100% test for reliability and durability to guarantee your signal integrity.

數位音頻訊號轉換器
專為插座面板系列產品所設計的簡易訊號轉換器。
閉路電視視頻平衡/不平衡訊號轉換器允許基頻混合訊號透過單向非屏蔽雙絞線電纜，用於多種電纜。
閉路電視平衡/不平衡訊號轉換器可利用雙絞線以取代昂貴的同軸電纜，包含從遠端錄影機到撥放系統的一對訊號、影像檢索、安全監控螢幕應用。
可使用現有公共建設之雙絞線像是電話線、Cat.5電腦網路線亦可利用，我們所有的平衡/不平衡訊號轉換器皆都100%檢測可靠性與耐久性來保證你的訊號完整。
