4CH Passive Video Balun For RJ45 Twisted Pairs to BNC, HD-CVI/TVI/AHD Analog Signal by UTP Cable

Overview:

The HD Video Balun converts video signals into a balanced format, allowing transmission over standard Cat-5 unshielded twisted-pair cabling. It is designed for applications such as video surveillance, video conferencing, and other scenarios requiring long-distance video transmission. This device simplifies wiring projects and reduces cable costs by enabling the transmission of four video channels simultaneously over a single 8-core Cat-5 cable.

Key Features and Benefits:

• Broad HD Video Compatibility:
  • Supports HD-CVI, HD-TVI, and HD-AHD video formats.
  • Compatible with NTSC, PAL, and SECAM video systems.
• Extended Transmission Distances:
  • HD-CVI: Up to 450m (720P), 250m (1080P).
  • HD-TVI: Up to 250m (720P/1080P).
  • HD-AHD: Up to 320m (720P), 250m (1080P).
• Efficient Cabling:
  • Transmits four video channels over a single 8-core Cat-5 cable.
  • Reduces cable usage and installation complexity.
• Superior Signal Quality:
  • 60dB crosstalk and noise immunity for clear video transmission.
  • Built-in transient suppression for enhanced reliability.
• Passive Operation:
  • Requires no external power supply.
