As the inventor of HDCVI (High Definition Composite Video Interface) technology, Dahua continuously invests in the technology to rejuvenate existing coaxial-based systems since its launch in 2012 with its own patents. As the first to bring 4K resolution over coax, the first to introduce IoT into analog monitoring, and with versatile offerings such as multi-sensor and fisheye cameras, Dahua has formulated its HDCVI camera selection as the perfect choice to strengthen your existing coaxial system. Dahua HDCVI cameras are separated into the Pro, Lite and Cooper Series, which range from high performance with project oriented features to a cost/performance balance. Users can select cameras based on their needs. HDCVI cameras are used in applications where existing analog infrastructure is available and users have a need for the latest technologies, including 4M/4K resolution, IoT over coax, Power over Coax (PoC), and more.
The Pro Series is a perfect choice for SMB solutions and projects where both high reliability and flexibility are required. All cameras are equipped with Starlight feature, true WDR and 3DNR, and are able to provide clear images and rich details even under tough lighting conditions.
The Lite Series is suitable for users who want high quality at a reasonable price. It features a superior cost/performance suitable for residential and small-medium business applications. The series offers a wide range of resolutions with Full-color/Starlight/general options to fit every scenario.
Cooper Series offers simple and highly cost-effective HDCVI solutions. It meets the requirement of 24/7 reliable monitoring with high-quality image performance, and saves budget for customers on both device and labor. Cooper is also highly guaranteed by Dahua quality standard.
Active Deterrence Series provides multi-dimensional system that links video with audio, information and alarm to verify potential risks. Active deterrence camera can actively warn off intruders with light and siren, alert users in real-time with alarm-over-coax and provides visual verification with HDCVI video.
Panorama Series offers fisheye camera and multi-lens camera for different scenarios. It can cover an extremely wide angle with only one camera, which greatly simplifies system installation and maintenance.
PoC Series features camera powered directly by the recorder over the same coaxial cable in which video is transmitted. Dahua PoC transmission distance can reach up to 400 meters for AF cameras and 200 meters for AT cameras, that can help decrease material and installation cost and simplify the system.
Micro-size Series provides various options for scenarios that require small size cameras. Its compact design is environment-friendly with large angle of view, minimizing the interference to on-going activities.
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.
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.
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.
Whether in constructing a new system or upgrading an existing obsolete system, the deployment of an HDCVI solution requires only minimal basic labor and costs. Users are able to enjoy the advantages of modern technological innovation with their existing analog infrastructure. Even if the current system is using other HD-over-coax technologies, HDCVI is perfectly compatible and can be easily integrated, owing to its full compatibility with HDCVI/AHD/TVI/CVBS/IP. HDCVI devices are always plug and play, making construction flexible, and enabling no-hassle network configuration. In addition, HDCVI systems allow the reuse of existing cables as it is compatible with both coaxial cable and UTP.
