Pair of Mini Balun Dahua Mod. PFM800-E designed for the transmission of CCTV video signal through a twisted cable, compatible with CCTV cameras with standard: AHD, HD-CVI, HD-TVI, PAL, NTSC - Blister packaging.
The device adapts the impedance of the 75 Ω coaxial cable to the impedance of the symmetrical cable ensuring the transmission of the CCTV video signal at a distance of 400M in CVBS resolutions. 250m in HD Ready resolution 720p or 150M in resolution FULL HD 1080p (via twisted cable CAT 5e / 6). Protection system for eliminating asymmetric interference on the video signal.
Made in black ABS (rigid plastic) housing, equipped with a joining system so as to join several balun enclosures to each other. The reduced dimensions favor the connection of the Balun even if the BNC sockets are closely flanked. The spring clamps for twisted pair allow a quick assembly without tools.
In practice, they convert the coaxial cable to a simple UTP telephone cable (twisted pair)
The advantage is given by the fact that the telephone cable costs considerably less than the coaxial one.
