Many residential and commercial properties still rely on traditional coaxial CCTV cabling. Replacing the entire cable infrastructure with Ethernet wiring is costly and time-consuming. This is where Dahua HDCVI (High Definition Composite Video Interface) cameras stand out. As Dahua’s patented analog HD technology, HDCVI delivers lossless long-distance transmission, zero latency, and ultra-high-definition video over existing coaxial cables, making it the perfect solution for legacy system upgrades.
Unlike standard analog cameras that output blurry SD footage, modern Dahua HDCVI 6.0 PLUS devices support up to 4K real-time resolution, 16:9 widescreen output, starlight low-light imaging, and stable signal transmission up to 500 meters via regular 75-3 coaxial cables. No network configuration is needed, plug-and-play operation drastically reduces installation and maintenance costs.
At GuestCN, we stock a full range of affordable, high-performance Dahua HDCVI cameras for every scenario. Here are our top-recommended models for old system retrofits and new coaxial surveillance setups:
