The pack contains one transmitter balun (camera end) and one receiver balun (DVR\/monitor end), both terminated with BNC connectors on one side and push-fit terminals for CAT5 cable on the other.\u003c\/p\u003e\n\u003cp\u003eDesigned for CCTV installations where coaxial cable runs are impractical or where existing CAT5 infrastructure is already in place, the baluns support HD analogue video formats (AHD, TVI, CVI) as well as standard-definition analogue CCTV. The passive design requires no external power supply — video signal transmission is powered entirely by the camera and recorder at either end of the cable run. Each balun measures 115mm x 102mm x 26mm and weighs 56g, making them compact enough to fit inside junction boxes or behind wall plates.\u003c\/p\u003e\n\u003cp\u003eThe transmitter and receiver are colour-coded with red and blue cable grips to prevent installation errors. The BNC connectors are nickel-plated brass with knurled coupling rings for hand-tightening without tools. The CAT5 terminals accept individual twisted-pair wires via push-fit screw terminals, with polarity marked on the balun housing. The baluns work with both shielded and unshielded CAT5\/CAT6 cable, though shielded cable is recommended for outdoor or electrically noisy environments to reduce interference.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.056\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.062\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e13.9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e115\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e102\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e26\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e430\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e350\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_HDBALUNV_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat video formats do these baluns support?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe baluns support AHD, TVI, CVI (all HD analogue formats) and standard-definition analogue CCTV video.

Exact distance depends on cable quality and environmental interference. For longer runs, active (powered) baluns are recommended.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo the baluns need a power supply?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. These are passive baluns, meaning they require no external power. Video signal transmission is powered by the camera and DVR\/recorder at either end of the cable. Only the video signal passes through the balun — not power for the camera itself, which must be supplied separately.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use these with IP cameras?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. These baluns are designed for analogue video signals (AHD, TVI, CVI, standard analogue CCTV) only.
