Why HDcctv?

Your Strategy for HD Surveillance

Whether you manufacture, distribute, or install surveillance equipment, or your company’s components are designed into cameras, DVRs, monitors, encoders, or you provide companion components such as cables and connectors, it is likely that you are paying attention to developments in HD surveillance video transport technology. The following decision tree illustrates the reasons for which so many companies addressing the Digital HD market are joining the HDcctv Alliance:

Why HDcctv?

HDTV looks better than PAL/NTSC. HDcctv 1.0 is a digital interface that delivers HDTV signals without any compression artifacts or transmission-related delays. HDcctv fits the cost-effective system architecture that has proven so useful for conventional CCTV systems. As a result, HDcctv 1.0 unlocks HD for CCTV customers. 

Until 2010, the only option for HD resolution was to adopt MP IP cameras. Now, HDcctv cameras are an alternative. With HDcctv, security installers no longer need to extend a local-site IP LAN all the way to every HD camera mount in order to deliver the benefits of HD video. HDcctv 1.0 cameras re-use most existing coaxial cables, making it possible to easily upgrade some CCTV cameras, one by one, to Digital HD surveillance without any fuss. Meanwhile, by sending the video signal with no compression and without delay, HDcctv cameras usually deliver better live views than the MP IP camera alternatives. These advantages make HDcctv cameras worth considering also for applications that blend local-site security operations with remote, IP-network-connected security management.



Why are “HD-SDI” cameras more widely available than certified HDcctv-compliant cameras?
•    Generation 1 HDcctv products incorporate chips whose designs pre-date HDcctv 1.0
•    Most pre-HDcctv-1.0 chips do not implement all the functions needed to certify a camera as HDcctv compliant

Why are HDcctv camera prices similar to those of CCTV cameras?
•    The camera architecture and dominant make-cost factors in HDcctv and CCTV cameras are identical, so manufacturing costs are very close at similar volumes

Why do Generation 1 HDcctv DVRs cost more than CCTV DVRs?
•    HDcctv presents 6 times as many pixels to process
•    HDcctv presents 6 times as many pixels to store
•    No specialized multi-channel receiver (RX) chips were available when Generation 1 HDcctv DVRs were designed

Why do manufacturers expect Generation 2 HDcctv DVRs to cost about the same as CCTV DVRs?
•    More pixels to process than CCTV: Higher-performance pixel-processing chips are now available
•    More pixels to store: Hard disk drive prices are declining; meanwhile, compression chip performance is increasing (even as prices continue to decline)
•    Need specialized multi-channel receiver (RX) chips
o    The first HDcctv-ready Quad Receiver ASIC was introduced in April 2012

What are the advantages of HDcctv cameras over MP IP cameras?
•    HDcctv cameras deliver the highest-quality HD live views
•    HDcctv cameras and DVRs are as easy as regular CCTV cameras and DVRs to install and set up
•    HDcctv cameras and DVRs can usually re-use legacy cabling

What are the disadvantages of HDcctv cameras for HD surveillance?
•    HDcctv cameras can be more expensive than MP IP cameras for large spaces that are sparsely covered with cameras
•    No wireless solution is yet available for HDcctv
•    HDcctv cameras transmit only HDTV video: 720p25/30/50/60 and 1080p25/30. Customers who need higher frame rates or higher resolution must turn to MP IP cameras


HD Live Views

HDcctv cameras give the best live views, because no compression is required for transmission and there is no IP LAN in between the camera and a monitor on the local site.
