What is the security industry view about HDcctv over coax?
At the last IFSEC gathering in Birmingham 2012, the real buzz around the NEC was about this “new” technology that allowed us to send HD images over RG59 coax. The number of exhibitors that were showing various HD SDI CCTV products had grown from the previous year almost 10 fold and to many of the attendees it was a new concept to them after the constant hype that previously had surrounded IP
Why should they be surprised by the concept of HDcctv over coax? Well as an industry we had been told/conditioned to believe for many years that HD quality images could only ever happen over an IP network. We thought we would never see old coax being re-used and quite frankly believed that it all needed to be replaced by CAT5 as the HD revolution started to take hold.
Of course HDcctv is not quite new . The concept had been turned into reality around 2009 . What is remarkable is the speed from which it has gone from a simple idea thrown around in a discussion between an elite few to a real workable product that will help to shape the CCTV industry for the next 10-20 years.
HDcctv has its place. The desire to re-use an existing cabling infrastructure will seem like a very good idea to those companies who invested heavily in analogue and RG59. Small installations of 4,8 and 16 ways will be prime targets for salesman looking to push their HD SDI DVR and cameras. However the HDcctv alliance has been looking to add to their standard and get alliance approved HDcctv products to work over existing and new CAT5 as well as coax. This opens up a whole new world of opportunity for both upgrades and new installs.
So what does the future hold. As cost of equipment plummets as more volume is produced then soon HDcctv will cost the same as analogue. At that point end users will see little point in continuing to upgrade analogue with analogue, so faced with the choice between HD SDI and IP they will probably go for the most cost effective solution, time will tell what that will be.
HDcctv DVR, technology of the future.
Todd Rockoff of the HDcctv alliance recently gave a full interview to the news and information site Integrated CCTV.
Here at HDcctv solutions we re-publish the interview for all our visitors. It does highlight how important the HDcctv alliance is to the future of HDcctv over coax and we fully endorse the comments and views that have been expressed in this excellent interview.
So here is the transcript in full.
1 ) Todd when it comes to lenses there currently seems to be few
guidelines. What lenses are the correct lenses to use – will the
alliance regulate or at least stipulate the required lens
specification for use with HDcctv cameras?
2) With HDcctv Recorders a lot of focus is spent on the quality of
locally recorded images and this obviously affects bandwidth and
storage – but there is a huge market for remote monitoring that
analogue covers right now, will recorder manufacturers consider
features such as throttled/reduced quality transmission for remote
monitoring?
3 ) Is it possible for MP resolution to increase in the future and if
not will HDcctv be able to compete with ever increasing IP camera
resolutions at decreasing prices?
4 ) Over the last 5 years the use of cat 5 and ballum technology has
meant less coax out in the field. We know plans are afoot for HDcctv
over cat 5 but when will this be viable and ready to sell to end
users?
5) One argument for IP is PoE .Is there any development of technology
that would send power to the camera down the coax like the old line
fed systems?
6) We hear of major developments with regard to chip technology that
will make HDcctv both better and cheaper. Can you outline exactly what
the benefits will be and when it will be available?
7) You have campaigned long and hard to convince the industry that
HDcctv compliance is the way forward. Few disagree but is there signs
of more members coming on board and do you think by not joining
manufacturers who are just selling HD SDI without standardizing risk
being marginalized.
8) This year at Ifsec the bias towards HD over coax was obvious and
Samsung are one of the big names we see that are almost reluctantly
deciding they have to join the fray. Why the reluctance originally on
their part?. Will they be joining the alliance? And are there other
big name manufacturers waiting in the wings to launch HDcctv over
coax?
9) Have you seen a marked increase in feature rich HDcctv DVRs as
manufacturers start to push for market share. If so, what features do
you think are bringing the most benefit to end users and what features
that we are yet to see should the manufacturers strive to introduce?
10) HDcctv cameras come in many shapes and sizes but is there
companies out there that have developed HDcctv PTZ domes. If so who?
11) IMS predictions have shown exponential growth in the sale of
HDcctv solutions across the world but where do you expect to see most
sales to end users taking place.
12) Recently the BBC ran an article on HD CCTV in the UK and the
threat to privacy this represented. It certainly bought the subject to
the fore here in the UK but what is your thoughts on this article and
is HD a threat or a benefit.
13) The argument for HD IP verses HDcctv seems to have died down
recently with an acceptance in the market place that each technology
fits well into the right application can you expand on where you think
HDcctv is best suited and why?
14) since 2009 HDcctv has seen a massive rise in awareness amongst the
public but are you happy enough people understand the potential and
what can be done to further raise awareness about HDcctv?
15) If we fast forward 5 years to 2017 what do you think commentators
will be saying about the HDcctv alliance and HDcctv over coax/cat5 in
general?
16) Can we expect anymore announcements or surprises in the field of
HD over coax and are you able to give anything away to us and our
readers today?
HD cctv over coax 2012
HD cctv over coax.
So what did the IMS research say about HD cctv over coax and how things will work out for this technology in 2012.
Well we have been following this closely over the last year and have seen some major developments over the last 12 months. Mainly on paper though. The promise of HD over cat5 and advances of the sort of distance and cable quality that can be used are being addressed mainly by the HD cctv alliance and this is to be commended. How have sales advanced though over the last 12 months and how will these progress over the next 12 months and beyond. Will it be HD-SDI or HD cctv?
It has to said that the idea of HD cctv over coax is an attractive one , especially here in the UK. A combination of a mature, saturated market here and the desire for HD means that by retaining existing infrastructure but delivering better picture quality will mean that HD cctv over coax must get some market share, how much though will surely come down to price and interoperability.
As the IMS research points out the reason for a muted response for demand in 2011 was perhaps a lack of education. We know of several companies that are still to even hear of the technology and this news for those hoping for a rapid expansion for HD cctv over coax is disappointing.
However this said, there does seem to be an unstoppable movement towards HD SDI DVR and HD SDI camera solutions. The IMS predicts a doubling in sales and we expect to see more players other than Everfocus starting to really push for market share in 2012. The Samsung SCB-6000 HD SDI camera will prove a popular choice and has begun to turn heads already, also expect to see Samsung push their HD SDI DVR the SRD 480D as well this year.
So in summary for HD cctv over coax to really make an impact in 2012 the IMS say that Standardization is crucial ( the HD cctv alliance are currently striving for this). Storage costs must come down …well we have a problem with this early 2012 that’s for sure with hard drive shortages driving up the cost of storage. Finally market education is crucial. This is true however if this plug and play solution does become affordable the market will not take long to realize that its easier than IP and less “education” is required. The problem at the moment seems to be that getting the word around about how effective HD cctv over coax could really be here in the UK.
Finally we need to think about the chip manufacturers, will they come up trumps and produce chip technology that makes HD cctv over coax an even more affordable solution?….lets wait and see.
Norbain promote IP CCTV solutions in the UK
Selling CCTV in the UK today is interesting to say the least. We have options available today that allow us to integrate all sorts of solutions together. So its with interest that we read the comments of Barry Shakespeare in this months copy of Security matters. In the November edition Barry looks towards the future and predicts what Norbain see as the way forward and talks about how they are preparing for changing times ahead.
Norbain see IP as the way forward
It is well known that Mr Shakespeare has come from a IP background and it is perfectly understandable that he backs IP as the way forward. His beliefs are of course backed up by all the big manufacturers who themselves have committed to IP as the future upgrade path for both IP video and integrated security solutions.
Last week Norbain held a seminar where they were able to talk about the benefits of IP and allow their industry partners to demonstrate their wares to installers and integrators alike. IP was the strong theme and during the course of the presentation Barry predicted that IP would reach tipping point at sometime around the end of 2013. Now we have heard this before and there is no doubt more and more end users are becoming aware that when the time comes for upgrade then IP is probably the way to go.
Installers struggle with IP ?
The same however cannot be said about those installing CCTV solutions. It was surprising that so many of the invited delegates did not install IP as their first preference and many had suffered some pretty bad experiences when trying to “get with the times”. The launch of Norbain’s own IP centre of excellence to train their staff can only help those troubled installers who seem to struggle to move on. Also other concepts that Norbain are introducing such as innovation centres and services that include pre-tested and configured IP CCTV systems will certainly encourage sales.
HDcctv makes a quiet appearance .
Perhaps though the most interesting thing that was not really touched upon was HDcctv and the opportunity to installers that this offered. Only quietly promoted were the new offerings of HDcctv DVR’s from both Samsung and Vista / Norbain themselves that allows HD over coax. It is our belief that HD will drive sales not IP. Until now IP has been the only way deliver HD to end users so its no surprise that IP has been hailed as the future. Remember however, the UK is a mature market place. Many millions of pounds have been invested in a coaxial infrastructure, why throw this investment away. Realistically recession is round the corner, just when we thought we were out of the woods. New system sales will be hard to come by so the salesman that can demonstrate improved quality and performance (HD) over an existing network has to have the commercial advantage when selling CCTV solutions in the coming months and years.
2013
We don’t see 2013 as the tipping point to IP. We don’t see 2013 as the end of analogue CCTV. We see 2013 as the tipping point to HD CCTV and the only question is how will that be delivered into the UK CCTV market place. Will it be HD over IP or will it be HD over coax? Answer that question and that will be where the real money will be made installing CCTV over the next 5 years.
