The Dahua HDCVI technology has been leading the HD-over-Coax industry’s development since its first launch in 2012. With its mission of “Enabling a safer society and smarter living”, Dahua has been continuously active in providing more opportunities to customers as well as improving its services with innovations and technological advancements. In 2019, Dahua unveils a brand new HDCVI 6.0 technology with core values including 4K Real-time, Enhanced AI, AI Coding and Two-way talk, achieving “clarity, abundance, and understanding” in monitoring.
Dahua self-developed chipset realizes industry-leading 4K real-time over-coax transmission. 4K@25/30fps camera video output better restores the monitoring scene with superior clarity and fluent visual experience. And 4K real-time camera supports self-adaptive video output frame rate to adapt both new and previous 4K XVRs.
Adopting independent AI chip and advanced deep-learning algorithm, HDCVI 6.0 enables precise recognition of human and vehicle for accurate alarm and quick target search, making it easy for users to focus on real threats, enhancing video analysis efficiency, and thus significantly reducing labor costs. HDCVI 6.0 Enhanced AI guarantees alarm accuracy, with false alarm rate below 2%. HDCVI 6.0 also supports AI functions including SMD Plus, Perimeter Protection, Face Recognition and Metadata Search.
As video moves toward high definition, video encoding formats have also developed from H.264 and H.265, which can save more storage space but in expense of image quality loss. The HDCVI 6.0 AI coding puts emphasis on human and vehicle while encoding, which guarantees the image quality of the target. AI coding based on CBR only needs 50% of bandwidth and storage costs compared with H.265.
HDCVI Two-way Talk is a unique and leading technology in HD-over-Coax industry. It realizes intercommunication between the monitoring center and the monitored site in the video surveillance system. It is able to deliver vocal info instantly and receive feedback at the same time. Also, the recording contains audio evidence from both sides. HDCVI supports broadcast-quality audio, with more than 20dB SNR and 5 meter audio collection range.
4K Real-time Application – Casino
In critical areas with large crowd of people and busy on-going activities, it is of utmost importance to catch every detail in real time to prevent unwanted behaviors and retain unquestionable visual evidence.
4K Real-time XVR + 4K Real-time HDCVI Camera In monitoring scenes like casinos where stakes are high, the 4K camera captures images with ultra-high definition to provide clear tiny details and real-time video output that presents fluent visual experience, effectively restoring the monitored scene.
SMD Plus Application - Store
Most crimes happen during non-business hours when the monitored site is lacking security guards. Users may fail to take action in time and suffer property loss in case of an event.
Lite AI(Wizsense) XVR (SMD Plus Feature) + Full-color Camera When a person or vehicle intrudes the monitored scene, the SMD Plus feature identifies potential risk and sends alarm to the user immediately. At the same time, the Full-color camera can provide 24/7 surveillance in full color.
Metadata Search Application - Street
Searching for a target in massive recordings costs large amount of time and labor. The accuracy of restoring a target greatly relies on the clarity of the image, especially the clarity of details.
Lite AI (Wizsense) and Pro AI (Wizmind) XVR (Metadata Search Feature) + Full-color Camera With Full-color HDCVI camera, restoring targets is easier and more accurate, especially their color details. Its Metadata Search function retrieves human/vehicle targets using attributes, such as hair and clothes color, vehicle color or car plate. This significantly enhances search accuracy and efficiency.
Two-way Talk Application - Warehouse
The monitoring site does not have enough security guards. If an intrusion happens, it would be difficult for users to take action and stop the crime immediately.
In application scenarios like a warehouse, the security guard at the monitoring center can warn off intruders with voice warning through the two-way talk system without being at the monitored scene.
