HDcctv Alliance , a global security industry consortium established to manage and promote technical standards for HDcctv equipment interoperability, announced that its voting members have ratified version 1.0 of the HDcctv (high-definition closed-circuit television) Specification. HDcctv alliance members are already introducing HDcctv-compliant products displaying the HDcctv logo.
"HDcctv is perhaps the first new product category in 10 years to be introduced into the surveillance industry, a new way to provide high resolution on selected cameras on the premises while preserving the existing surveillance system architecture." said Todd Rockoff, Chair of HDcctv Alliance.
"Prior to the advent of HDcctv systems, the only way to achieve high-resolution video surveillance was to install network cameras, which can be costly and present technical challenges to the installer and security professional," Rockoff said. "HDcctv squeezes new value out of existing surveillance cabling infrastructure. HDcctv is profitable for the manufacturer, dealer and installer since it is a high margin, high technology offering that is a cost effective, easy upgrade for customers."
The HDcctv v1.0 Specification and all future specifications adhere to the principle that the user/installer experience must mirror an analog surveillance installation, usage, and maintenance experience with the best aspects of analog surveillance retained, including plug-and-play installation, a secure closed loop for information transmission, and negligible video transmission latency.
In an HDcctv-based system, HDTV signals are transmitted digitally over conventional surveillance media without packetization or any perceivable compression latency. HDcctv is a zero-training, plug-and-play resolution upgrade for the installed base.
The HDcctv v1.0 Specification is an open industry standard that accommodates the growing broad adoption of HD video formats by both surveillance equipment manufacturers and security service providers within the surveillance industry. The specification defines the requirements for a flexible system and apparatus capable of creating, transporting, distributing, recording and displaying HDcctv video and metadata. A scalable digital interface with support for external box-to-box digital interfaces is defined with optional audio, metadata and data capability for broad application for surveillance devices.
The HDcctv Alliance has partnered with SMPTE (Society for Motion Picture and Television Engineers) to include the family of video interfaces known as HD-SDI, covering transmission of 720p and 1080p formats, among others, at data rates around 1.5Gb/s, to create derivative standards to enable plug-and-play security systems and equipment that deliver high-resolution, HD surveillance video with no delays, image artifacts, or visible jitter.
Under the license agreement with SMPTE, the HDcctv Alliance has quickly developed v1.0 of its specification by directly reproducing many of the key technologies and requirements of HD-SDI, while adding new capabilities and formats tailored to the unique needs of the surveillance industry. Subsequent versions of the HDcctv specification will build on the v1.0 Specification to provide for advanced features, such as 300-meter signal transmission, up-the-cable control, bidirectional audio and up-the-cable power.
