There are not many solutions available today for this integration, but HDcctv will soon be integrated with IP much like analog is today, mostly by delivering Hybrid DVR’s which can record and display analog, IP or HDcctv. A few companies are developing HDcctv to IP streamers which may find an application in larger systems, allowing HDcctv feeds to be captured by NVRs. We have been offering a PC-based solution with HDcctv and analog in the same system for a while now.

 

HDcctv Specification

The HDcctv Specification comprises a suite of standards documents developed by the HDcctv Alliance Technical Committee. These documents specify operational requirements and compliance levels for HDcctv systems from “glass-to-glass” (camera to display).

The HDcctv Alliance is the trade association for the HDcctv global industry. Visit the web site www.highdefcctv.org for updates on standards and well as training webinars and listings of member companies and their products.

The purpose of any standardization and compliance process is to ensure “interoperability” of products, components and systems designed and tested in compliance with the standard. Equipment displaying the HDcctv logo - developed by HDcctv adoptor companies - is assurance of a compliant product or system that will provide a “plug-and-play” digital high-definition CCTV experience for system installers and security professionals alike.

Planned versions of the HDcctv Standard offer successively greater cost effectiveness for surveillance, by adding capabilities such as 2-way communications and up-the-cable power and by increasing performance such as 300m transmission over low-grade RG59 coaxial cable and pixel arrays up to 20 million pixels per frame.
