What is HDCVI technology?

By | November 22, 2017

Video surveillance is an integral part of security for countless organizations worldwide. Yet while the capabilities of these systems continue to improve, such as higher resolution and intelligent analytics, businesses are often restricted in the system design process by older infrastructure that doesn’t support the latest technologies. Unfortunately, high system design costs, technical challenges and other factors impede many companies’ efforts to upgrade their surveillance systems.

Enter High Definition Composite Video Interface (HDCVI) technology. HDCVI is a video standard that enables users to transmit HD video over existing coaxial cable infrastructure—ideal for lowering costs and maximizing return on investment.

First introduced by Dahua in 2012, HDCVI’s capabilities have been expanded over the years. The current standard, HDCVI 3.0, has a few key attributes that make it well-suited for a broad range of vertical markets.

4K / Ultra HD capability

HDCVI 3.0 is the first technology to provide up to 4K resolution in systems based on a coax infrastructure. It also boasts Starlight technology, allowing for crisp, clear, images in near-darkness, down to 0.008 lux. Wide Dynamic Range (WDR) of 120dB to 140dB, depending on the model, further supports the camera in challenging lighting environments.

Video technology compatibility

HDCVI 3.0 pentabrid recorders are compatible with all five of the primary video technologies offered in video surveillance: standard analog, AHD, IP, HDCVI, and HDTVI. Because it is backwards compatible, HDCVI 3.0 enables use of existing standard definition analog cameras while also receiving input from IP cameras. To that end, HDCVI 3.0 stands out for its ability to integrate several technologies within one system.

Digital video recorders (DVRs) using HDCVI 3.0 can serve as an access point for multiple security services, and integration is planned with external passive devices such as alarms, infrared sensors, and others. Video, audio and control signals and power are combined in a single cable. Both coaxial cable or unshielded twisted pair (UTP) cable can be used, and wireless transmission capability is currently being developed. Third-party integration with other network video recorders and video management software solutions is made possible by ONVIF Profile S conformance.

Intelligent feature support

Intelligent features – e.g., smart tracking, face detection, people counting, heat mapping, and smart scene adaption – are supported by HDCVI 3.0. As a result, users can enjoy greater system functionality than would otherwise be possible on an analog system.

Some other intelligent features are intrusion detection, virtual tripwire, detection of missing and abandoned objects, and scene change. Because system design can be simplified and rip-and-replace costs are eliminated through HDCVI 3.0, these features can be enjoyed at with a lower overall investment.

Types of applications

End-users in vertical markets such as banking and gaming will be particularly interested in HD and UHD HDCVI, seeing as these types of facilities have a great need for detailed images without latency, yet often have legacy coax cabling. HDCVI offers high enough image quality to see the fine details of cash transactions and card games, for example. For some businesses, coax cable may actually be the preferred transmission mode, since it reduces the concern of network security.
