Dahua HDCVI Recorders
Dahua HDCVI (High Definition Composite Video Interface) Recorders include the Ultra, Pro, and Lite Series to fit various applications. Ultra Series recorders offer the best performance and highest quality. Pro Series devices are perfect for mid-large size businesses and projects which require a balance between performance and budget. Lite Series recorders are designed for optimum cost performance with Dahua quality assurance standard.
HDCVI Recorders, as a part of an HDCVI system, are widely used in applications where existing infrastructure is available and users have a need for the latest technologies like 4MP/4K resolution, IoT over coax, Power over Coax (PoC), and more.
As the inventor of HDCVI technology, Dahua is committed to bringing the latest technologies to existing coax-based systems, enabling users to enjoy the latest innovations and industry developments.
HDCVI Technology
HDCVI is an over-coaxial cable video standard that enables long-distance HD video transmission over a wide range of application scenarios at a friendly cost.
Ultra High Definition
HDCVI technology supports up to 4K ultra high definition resolution. With 4 times the pixels of 1080P, it presents a true-to-life image with impressive clarity that captures even the tiniest of details. As the very first technology to bring 4K-over-coax to the market, HDCVI comes with a complete product portfolio. The 4K box camera (DH-HAC-HF3805G) features Starlight capability and offers a full color image even in extreme low-light environments. The 4K IR bullet and dome cameras (DH-HAC-HFW3802E-Z & DH-HAC-HDBW3802E-Z) feature 120dB true WDR and long-distance IR range. The 4K multi-sensor camera(DH-HAC-PFW3601-A180) and fisheye camera (DH-HAC-EBW3802) capture a panoramic image which covers a wider monitoring area.
4 Signals over 1 Coaxial Cable
HDCVI technology can simultaneously transmit 4 signals (audio, video, data, and power) over 1 coaxial cable. HDCVI cameras offer high resolution video, support audio input or built-in mic, and communicate with the HCVR through control signals. Moreover, Power-over-Coax (PoC) technology has been made available for integrated power-supply requirements. HDCVI cameras are able to cover multiple signal acquisitiondemands, further simplifying the installation and deployment of surveillance systems.
Long Distance Transmission
HDCVI technology guarantees long-distance transmission in real-time without any signal loss. Based on real-world scenario testing in Dahua’s test laboratory, it supports the following distances at the corresponding resolutions.
