HDcctv?, So what's all this about then? Options

[Matt the Teckie]

My boss showed me an article in a trade magazine today regarding HDcctv and the HDcctv alliance.



After looking through the website and watching the videos clearly put together at a trade show, I'm still non the wiser about its usefulness in the security industry concidering the cable distance restraints, induced signal attenuation across coaxial cable and the benefits of MP IP cameras in a closed network environment.



Also, if a conventional analogue camera outputs interlaced 480TVL (520TVL at the most), what benefit does transmission at progressive 1080 lines deliver.



Does anyone out there understand the aspirations of this technology or know of any good resource information so I can better understand what's so great about HDcctv?



Cheers all

Check out their website: http://www.highdefcctv.org/. They use a technology based on serialized, uncompressed video to transport the signal, rather than IP. This is the same technology used for commercial television camera signals.

They claim the following advantages:

* Surveillance-Grade Reliability: Video is not broken up into packets and then transmitted via an occasionally congested network.

* Plug-and-Play Resolution Upgrade: Transition from CCTV to HDcctv is very easy; just upgrade the DVR and selected cameras.

* Familiar and Reliable User Interface: For the installer/operator, the only difference between HDcctv and CCTV is that the DVR recording configuration screens show higher values (1280 x 720 and/or 1920 x 1080) in the pull-downs for record resolution in addition to the conventional CCTV values.

* True HDTV Live View: HDcctv video signals are not compressed or packetized before transmission, so no compression image artifacts or frame interruptions are observed.

* Real-Time Speed Dome Control: HDcctv is compression-free, with none of the signal delays associated with compression. Therefore an HDcctv system operator experiences no delay between a joystick command and the corresponding speed dome (pan/tilt/zoom dome) response.

* Best Possible Input Format for Analytics: HDcctv systems digitally deliver crisp, unadulterated video from cameras to DVR for the clearest possible analytics input.
