You're right, HD *might* be easier. So far all we have to really go on is the marketing hype from the HDcctv Alliance.

What sort of price point for this stuff?

 

I remain skeptical - yes, it will give you magnificent-look full-framerate HD video to look at... and take about a terabyte per week per camera to store unless you recompress it.

I realize that... that's my point, it still needs to get compressed if you want any sort of decent retention time. And if retention is really critical, it will need to be resampled to a lower framerate as well. So as far as recorded footage, you end up back where you already are with analog and IP.

 

Unless it's in an application where watching the video in realtime is a *requirement* (such as casinos, etc.), that pretty much negates THE major stated benefit of the format.

I think of HDcctv as potentially the modern-day equivalent of our existing analog cctv system. Through our matrix switch, we get full resolution, full frame rate live video. In our case, that also gets recorded at full frame rate, although with some compression artifacting and detail loss. Nevertheless, using camera placement with an eye toward the final playback result, we can see everything we really need to see.

 

With HDcctv, we would be able to monitor the live video at a resolution that would be far superior to analog. We could also record at sufficient resolution to see what we need to see. Storage continues to become less of a factor as it continually gets cheaper per gigabyte. In fact, we could deploy at least three times the storage we have today for less than what we paid in 2006. Through judicious camera placement, we could also cut the camera count in many areas. That would also allow us to store the video at a higher quality or for a longer time or both.

 

That is one major problem I have with IP. There is usually no resolution difference between the live and the recorded video and the amount of compression is chosen for recording and transport bitrate considerations. Yes, I know some cameras can feed two separate streams, but that won't help the network.

Carl can u tell plz

What would you recommend for storage

working on project which may need 30-50 terabytes

Thanks

Alex check out http://www.pivot3.com/. The NVR software runs as a VM and adds redundancy to your system. Looked at it at ISC and it's good stuff.

Pivot3 and Intransa are two turnkey solutions, although there are other options. DAS, SAN and NAS solutions are available from a number of vendors. It all depends on your requirements and your choice of DVR/NVR/VMS vendors.

 

We chose DAS for our servers but would consider other solutions down the road as we migrate to IP and/or HDcctv. 30-50TB is do-able in a number of ways with a number of form factors. Some systems can handle that much storage in a single enclosure. Others would require multiple enclosures connected commonly to a network or controller. There are many variations.

Does any part of the HDcctv spec address transmission over twisted pair? I did not see much in that regard, and most casinos (the most likely user of it, at this point) seem to have at last some of their signal path over twisted pair.

According to some posts on LinkedIn by HDcctv Alliance staff and members, twisted-pair transport is something they are working on. There is no mention of a time frame for deployment of that option.

Curios how they going to handle several Gig/sec bandwidth over twisted pair

HD requires no IT experience, ease of installation, and superior image quality. The VTD-MVHD2812 is now currently available through VITEK (1.3Megapixel Mighty Dome Camera with 2.8-12mm Varifocal lens). Vitek will offer additional HD cameras within the coming weeks.
