Effortless 4K CCTV Transmission over Long Distances

Are you struggling with degraded video quality over long coaxial cable runs? The Dahua PFM800B-4K Video Balun solves the most common limitation in analog and high-definition security setups: distance. By converting your video signal to run over unshielded twisted pair (UTP) CAT5e or CAT6 cables, you can maintain pristine 4K resolution up to 200 meters (656 feet) or standard 720p up to an impressive 400 meters.

True Plug-and-Play Simplicity

Forget about running bulky coaxial cables and managing complicated power setups for your video transmission. This passive video balun requires zero external power. The integrated BNC male connector plugs directly into your camera or DVR, while the pluggable push-terminal connections make wiring your CAT5e/6 cable fast, secure, and tool-free. It’s designed to save you time on every installation.

Built for Professional Security Environments

Interference and power surges are the enemies of clear security footage. Dahua has engineered the PFM800B-4K with superior anti-interference capabilities, ensuring your video feed remains stable even in electrically noisy environments. Furthermore, it boasts high-grade ESD and anti-thunder protection (up to 4KV common-mode), safeguarding your expensive DVRs and cameras from unexpected voltage spikes and harsh environmental conditions.
