The RULE CCTV Passive Balun RV-DP21T/R allows a single CCTV Power-Video

Signals to be transmitted via cost-effective unshielded twisted pair

(UTP) cable. Used in pairs, the CCTV Balun eliminates costly and bulky

coaxial cable, allowing CCTV security and surveillance equipment to be

connected using standard structured cabling techniques for neater and

more streamlined cabling.
