Dahua Technology USA is showing an all-new line of HDCVI 4.0 cameras and recorders at this year’s ISC West exhibition in Las Vegas, pictured, at the Sands Expo from April 11 to 13. Its six new 4K camera models will offer the highest over-coax resolution on the market, the company says. The HDCVI 4K camera feature a new generation of ISP chips, developed by Dahua Technology and optimised for video surveillance the firm says. The in-house chip can use coax infrastructures to lower the total cost of ownership for the user (TCO).
HDCVI 4K cameras have four times the resolution of 1080p with an approximate 16:9 aspect ratio, which represents the highest over-coax imaging resolution in the industry, it is claimed. Dahua’s latest HDCVI 4K line of cameras features Starlight Technology that produces color images in low light (down to 0.005 lux). Applications for high-resolution video, the company says, include financial and various facilities with mission-critical operations that demand high-resolution video over coax.
Jennifer Hackenburg, senior product manager at Dahua Technology USA, said: “Dahua Technology’s all new line of HDCVI 4K products will change the industry by not only offering 4K over coax, but also offering the first eight-channel and 16-channel HDCVI Digital Video Recorders that record 4K resolution on each channel. We look forward to showcasing these new products at ISC West 2018.”
Features of Dahua’s new line of HDCVI 4K cameras include:
Transmission
The use of network-based 4K technologies presents a challenge for applications that are not equipped to transmit large amounts of data over conventional IP infrastructure at long distances, the firm says. The HDCVI Standard enables analogue video transmission without requiring the use of repeaters – and enables the transmission of video, audio, and data all over a single RG6 coax cable. The technology enables transmission of 4K-quality video over coax of distances up to 700m (RG6), 500m (RG-59), or 300m using CAT6 cabling.
Audio
Available in bullet, dome, and eyeball form factors, the new A82A Series of HDCVI 4K cameras are for surveillance of large areas, capturing video with wide-angle overviews and multiple focus points while maintaining the ability to digitally zoom and focus on fine details. The A82A series comes with broadcast quality audio. Plus, the Eyeball and Bullet models offer a built-in microphone.
HDCVI 4.0 technology lowers total cost of ownership (TCO) by using existing infrastructure. By simplifying system design and mitigating rip-and-replacement costs to install new IP infrastructure, HDCVI 4.0 4K cameras can increase performance at a lower overall cost. Plus, the cameras feature a convenient multi-format video output cable on the camera’s pigtail for switching between AHD, TVI, and CVBS as well as existing HDCVI systems.
Data security
HDCVI cameras do not transmit data over a network, allowing the video feeds from these devices to be better protected against hacking. For users that require a hardwired system to ensure data security, HDCVI 4K cameras deployed over coax offer a high-resolution surveillance solution.
Storage
Dahua adds that it’s the first to market with an eight-channel and 16-channel recorder that records 4K video on each channel. This Penta-brid recorder supports HDCVI, AHD, TVI, and CVBS video signals and automatically detects the incoming format for set-up and configuration. The recorder also supports IP video signals, up to 8 MB per channel, and its Smart H.265+/H.264+ video compression offers storage management. Other intelligent features are intrusion detection, virtual tripwire, detection of missing and abandoned objects, and detection of a scene change. The addition of these smart analytics can the makers say improve overall surveillance and security for virtual application at any facility location.
