Dahua Technology, the manufacturer of video surveillance products, has released HDCVI 3.0, its next-generation analogue-to-HD video surveillance products.
HDCVI, also known as high definition composite video interface technology, was introduced by Dahua in November 2012. Since then it has become a standard for HD-over-coaxial-cable video transmission for HD transmission. HDCVI3.0 includes full compatibility with a range of industry platforms and technologies, higher video resolutions such as ultra HD and 4K, and intelligent functions equal to those in IP systems, the makers say.
Liquan Fu, President of Zhejiang Dahua Technology Co., Ltd, said: “The worldwide adoption of Dahua HDCVI technology is testament to its ability to address an industry need. With nearly two hundred million analog security surveillance systems deployed globally, HDCVI 3.0 is expected to have a far-reaching impact on the security industry for the years to come.”
Dahua HDCVI 3.0 integrates with five industry platforms, HDCVI, AHD, TVI, IP and analogue; and can accept input from IP systems. Digital recorders with HDCVI3.0 can act as an access point to integrate with external passive infrared sensors, smoke detectors and other types of sensors.
Dahua adds that HDCVI3.0 delivers what it calls a true end-to-end ultra HD experience to coaxial systems. It is the first technology that provides 4-megapixel resolution over coaxial cabling. Meanwhile, it also offers Dahua Starlight night vision that includes2-megapixel resolution at 0.008 lux illumination and 120dB wide dynamic range. Also, it features H.265 compression standard that allows the system to save up to 50pc bandwidth.
HDCVI3.0 features such intelligence features as facial recognition, people counting, heat map, smart tracking, and smart scene adaption. Other smart features include intrusion, virtual tripwire, missing object, abandoned object and scene change. Defogging and a voltage overload alarm are also included.
And the firm adds that HDCVI 3.0 systems offer the same simplicity and ease of installation as analogue systems, as the cameras can be plugged into the DVRs using coax cable. In HDCVI 3.0 systems power can be directly supplied over coaxial cable.
Another advantage of HDCVI 3.0 is the transmission distance compared to analogue. When transmitting general media, the signal can be extended as far as 1200m it’s claimed by using 75-5 cable, with a low signal distortion rate.
