DELTA TR-1CD*P2 Passive Video Balun Transceiver for CVBS/AHD/HD-CVI/HD-TVI, BNC to Screw Terminal, Up to 8MP 4K, 150-600m over UTP

For installers who need to send high-resolution video over existing twisted-pair cabling, the DELTA TR-1CD*P2 passive video balun transceiver eliminates the need for coaxial runs. Unlike active extenders that demand external power, this compact unit operates entirely passively, converting a 75-ohm BNC signal to a balanced signal for UTP Cat.5e/6 cable. It supports both legacy CVBS and modern HD-over-coax formats—AHD, HD-CVI, and HD-TVI—up to 8MP (4K), making it a flexible choice for upgrades and new CCTV deployments.

Highlights

• Passive design: no power supply required, reducing points of failure and installation cost.
• Supports CVBS, AHD, HD-CVI, and HD-TVI signals, with resolutions up to 8MP (4K).
• Built-in 2kV surge protection guards against voltage spikes on the video line.
• Compact ABS housing with BNC male input and screw terminal output for quick UTP termination.
• Extended transmission distances: up to 600m for CVBS black-and-white, 300m for 720p HD, 250m for 1080p, 200m for 4MP/5MP, and 150m for 8MP.

In daily use

The TR-1CD*P2 connects directly to the camera's BNC output, while the screw terminal block accepts a single twisted pair from the UTP cable. At the monitoring end, a second balun (or a compatible receiver) converts the signal back to BNC for the DVR or monitor. Because the unit is passive, it introduces minimal attenuation (<0.5 dB) and maintains a high common-mode rejection ratio (>60 dB) to reduce interference. The wide operating temperature range of -10°C to +50°C suits most indoor and sheltered outdoor installations.
