HD over coax

Posted on by | Leave a reply

HD CCTV over coax has gone from an untried theory into what is set to be one the  most interesting developments in the CCTV world since IP CCTV hit the scene 5 years ago . HD over coax has long been on the wish list of many CCTV installers. We all know the scenario of when a break in occurs, the images are just not good enough to recognise the perpetrators. Now we finally have the answer. That answer comes  in the form of  HD over coax. In the last two years there has been a trickle of companies producing HD SDI DVR’s and cameras, this has now started to become a flood as all the major players re- assess what will actually be selling most over the next 5 years.

IP CCTV has been pushed and manipulated in every form possible but has still to take the market by storm . The reason is simple, the cost to upgrade in a depressed market place has proved too much of a boundary to overcome for installers and end users alike. Customers want HD!  They expect to pay more for HD,  but in just about every case it means abandoning their investments from the past .ie their coax network. Add to this that most applications for HD are often only needed to be targeted on key areas and a whole new IP CCTV system seems too much over-kill for the benefits that will be gained.

Enter the HD SDI Camera, megapixel images over coax and a  HD SDI DVR that can incorporate existing analogue cameras together with  new HD CCTV solutions and suddenly you give the end user a real incentive to upgrade at a cost that is not going to frighten them off. One of the negatives of HD CCTV is often said to be that it lacks flexibility and future proofing. Well analogue CCTV has fundamentally remained the same for many years, its only weakness being poor images and stuttering recordings that lack credibility.

The reason for this? Well analogue has its limitations in the number of lines that can make up an image it can go no further as a technology. With HD CCTV we have addressed the issues, what else would you want from a CCTV system other than crisp clear images that work?

So can HD CCTV fill the gap in the market that has been sadly lacking for many years? Well quite simply yes. Quality images, quality recordings, the ability to enhance those recordings without the degradation normally associated with enhanced images. It’s cheaper and easier to install. Yes HD CCTV is here to stay !

 

HD CCTV hybrid HD SDI DVR

HD CCTV is taking the UK CCTV market by storm at the moment. The reasons are simple. Its because the technology is plug and play. Any existing analogue CCTV system can be upgraded and enhanced using HD SDI technology. The benefits of of an HD SDI DVR hybrid recorder is that it can take new HD SDI cameras as well as existing analogue CCTV cameras. This means that a company who has made a considerable investment in their existing CCTV system can upgrade parts of it to HD and still use analogue cameras in locations where high definition is not a requirement. The hybrid HD SDI DVR’s come in a variety of formats . The most popular though is the 16 way unit with 12 channels of analogue and 4 channels of HD. Most companies need HD on their entrance , reception, goods in, and car park while the other cameras around the site can remain in an analogue format. The option of the hybrid HD SDI DVR is proving to be the stimulus for many businesses in the UK to take the step up to HD CCTV with of course the option to go full HD across the whole site. HD CCTV also comes with the option to view images remotely through broadband access and the ability to zoom in on recorded images without losing noticeable definition means HD CCTV has come of age. The best part about all of this is that almost all existing CCTV systems currently out there in the UK can be upgraded and enhanced by using HD CCTV solutions

Back in 2010 Integrated CCTV interviewed Avigilon and asked them about the future. How far have they come since?  Well they are now probably one of the biggest names in HD CCTV here in the UK. Each year Avigilon HD go from strength to strength. Lets take a look back and see how much of what they talked about then has come true today. Comments welcome.

HD CCTV solves all the problems with CCTV

HD CCTV is being touted as the answer to every installers dream when it comes to upgrading and enhancing existing analog CCTV systems. But how does it work and what are the shortfalls if any? HD SDI CCTV cameras can produce images that can achieve 720p and 1080p video at a full 30 frames per second. Add to this the fact that upon delivery there is  no latency or use of compression of the image and you start to see the attraction of this technology.

To enable installers however to reach a balanced view there is a need to ask if  HD CCTV can replace or even supersede IP based HD CCTV cameras?

Many in the CCTV industry have asked if IP solutions will be blown away by this new technology. Well firstly we need to consider that 80% of the UK market place is still analog CCTV solutions and HD CCTV in the form of  HD SDI is definitely at an advantage to take the share of upgrades. but is it flexible enough when it comes to integration and will the advance to 10 16 or even 20 megapixel IP cameras mean that HD CCTV will be dropped in favour of IP?

HDcctv benefits


Firstly we need to understand exactly how HD CCTV works as opposed to IP HD cameras.  HD CCTV uses coax and has been developed on the back of HDTV and the technology behind the pictures we see on our TV sets today. It is not dissimilar from a standard analog CCTV system and uses coax to carry images of up to 2.1 megapixels from the camera to the DVR. It does not use cat 5 or existing IT networks this means there is no compression required and as a result no latency.

The primary benefit  to CCTV integrators is the ease of installation. Because HD CCTV can use existing coax or is wired as a point to point system, any engineer with basic knowledge of CCTV can install it. No IP addresses, IT managers interfering or network issues to contend with. Quite simply its plug and play. This makes installation simple, uncomplicated and best of all cheaper than many IP based systems. No new cabling makes a retro fit installation far more commercially attractive than an IP solution.

The ability of HD CCTV to re-use the same cabling infrastructure as most traditional analog systems is though the main selling point together with images that will impress even the biggest sceptics of HD SDI CCTV. One of the largest costs in any analog system conversion is the changes to the cabling infrastructure. This technology allows organizations an easy, economical way to upgrade a legacy analog system to achieve the benefits of megapixel cameras.


One of the main challenges to HD CCTV and its uptake in the UK has been the lack of companies who are able to offer a cost effective HD SDI DVR this however has most definitely been overcome. IFSEC 2011 was the tipping point with HD CCTV systems being the star of the show. It was almost like the consumers had forgotten about IP CCTV. Still more competition is required and hybrid HD SDI DVR’s seem the obvious path to upgrade.

One barrier to HD CCTV is that the resolution capabilities IP are far greater. HD SDI cameras can produce the max resolution being 2.1 megapixels. IP cameras have as much as 5 times that resolution and it is only bandwidth limitations that stop this being expanded further. However many years in the industry have taught us that anything much higher than 2 megapixels starts to become cost prohibitive and even though sometimes higher resolution might be preferable it is often not practical. When viewed 2 megapixels is generally accepted as quite sufficient especially when compared to the previous best offerings of analogue CCTV.

Of course IP will always have its needs and the larger the organization the more likely that IP will be the preferred solution. This however still leaves vast amounts of the market place open to HD CCTV and gives the wider population the access to HD that has previously proved too expensive.

So the question was is HD CCTV the answer to everything, well no its not but it is certainly going to provide a viable alternative to IP and one that will prove to inevitably be the preferred option to current CCTV installers and their huge user database.
