HD or not HD – that is the question

It’s 2010 and our industry is once again pondering the inevitable
question ‘when will IP catch on’!!??

For the past few years, experts have been predicting the demise of the
analogue camera and the true embrace of networked connected IP
cameras…….but with no-one really sticking their neck out and
stating when it will actually happen.

And this is, in part, because the industry is a wash with so many
fragmented technologies that installers and end users alike are
confused as to what is really available.

Take the latest greatest IP encoder and you are hooked on the quality
and ease of installation….then you ask what recording options are
available and you find yourself hooked into the same manufacturer to
ensure complete compatibility…….

What happened to using the Panasanyo camera with the Dedicated
Research DVR along with the Ademcobrain monitor?? Analogue, old
technology but at least compatible with each other!

Perhaps things are a changing……ONVIF is around the corner and
promises to ensure that any company that signs up has to ensure it
offers compatibility with other ONVIF contributors – we wait and
see……

Megapixel? Whats best? We are brought up to believe that the more the
number the better the specification…..a 5megapixel camera has got to
be better than a 2megapixel camera surely? Sure, but at what expense?
You need more HDD to store it (expense) and you need a good bandwidth
network to transmit it (expense) – of course, you can scale everything
back, throttle, dual stream, encode in CIF and all the other ways of
making the good quality image smaller and faster, but is that not like
buying a Ferrari and then only ever driving it at 30mph???

HD might change all this, at least in part to start with……High
Definition….. The very name smacks of expected quality…. If you
view a HD image, you are expecting a beautiful picture…..you want to
see the blade of grass on the ground and the badly shaven face of the
Serbian footballer on ITV 1 World Cup broadcasts (not wishing to spark
controversy but great result Serbs against the Germans!)……you want
to see the beads of sweat on the brows of ageing rockers on BBC
Glastonbury……..and HD delivers just that…….

And yet…..HD is merely 720p or at best, 1080p…… A mere 2
megapixels…… Pretty much at the maximum of what a really decent
monitor can display anyway…….but HD nonetheless

We saw a sneak preview of some of Sony’s IP opinions recently – HD is
their intended marketing vehicle……they think end users understand
HD…..they know that HD is embraced in the domestic sector…..and so
they are focussing their Security products as HD in order to gain a
quicker acceptance – and we think they are absolutely right

So why do we need more pixels? Maybe we don’t……just how many more
blades of grass do we need to see? Just how many more tufts of facial
hair on those footballers? And really, do we need to see more
perspiration on those rockers? If they are there, we just need to see
them and maybe even record them……for playback later……..just
like our security cameras

HD…..maybe that will kick us toward IP quicker!

IP CCTV.

IP CCTV has suddenly come to the fore in the last couple of years . It was particularly noticeable at IFSEC this year where analogue cameras seemed to be no more than an after thought . However what are the reasons that a CCTV camera format that has served the industry for so long should now so suddenly become a technology that will soon be confined to museums or very short sighted end users?

Life in the old dog?

Well perhaps that last statement was a little unfair. It will still take a while before we see analogue cameras disappear completely off the scene, perhaps long as 10 years, but in the meantime megapixel IP cameras will start to produce results that many organisations will find hard to resist. What results you may ask? Well for so many years every CCTV administrator has just wanted to zoom in on captured images and blow them up to prove an event has occurred. Up to now there has rarely been enough definition to achieve this goal . Any blown up or artificially enhanced images have been blurred or pixelated to the point where they are useless.

Why HD CCTV or Megapixel cameras.

Mega pixel especially does not however suffer this problem. The images remain clear and crisp as they are zoomed into on the played back recordings . Add to this stunning live images and you will understand why analogue is effectively dead. Examples of camera manufactures who have taken this technology and produced some excellent camera solutions include Avigilon, Arecont, 360 vision technology, Bosch to name but a few.

What is the catch?

So as the camera technology improves are there any drawbacks? Well of course there are . Due to bandwidth and processing limitations some of the 10 mp cameras can only deliver images at 3 frames per second. Slow to say the least but with such crystal clear images it is still better than 12 fps on an analogue alternative. Of course the camera technology may be slighty ahead of the networks that they need to deliver them to their recording solution ie CCTV software. However as CCTV software gets better and the speed and flexibility of networks increase as well as the processing power of the camera chips, we will eventually see the utopia in terms of megapixel technology and this can bring to the end user the ultimate CCTV solution.

Conclusion.

Are you an end user who is considering an upgrade? Perhaps you have upgraded already and are either impressed or disappointed in what you have purchased? Let us know your thoughts and we will be happy to publish them in order to help other organisations to make that important decision, to upgrade or not to upgrade?

CCTV in data centres.

We have recently been asked to look at IP CCTV solutions within Data centres. This is one of the fastest areas of expansion for security solutions within the country at the moment. The reasons behind this expansion are simple. Paranoia when it comes to the protection of company data and information. In addition demands from users when it comes to accessing this information are unparalleled they do not accept down time.Therefore there is always a  requirement for off site storage and redundancy.

IP camera solution.

Quite simply IP cameras are the only real option. The network is always going to be in place and most data centres understand the benefits that HD IP cameras can offer.When dealing with playback it is essential that the pictures give both quality and a frame rate that will mean anything that goes on inside the data centres does not get missed. The ability to record using a VMS solution is also now being viewed as crucial , storage on a server is what data centres do anyway and with VMS CCTV software you have the ability to zoom in without losing image quality and suffering from the age old issue of pixelation.

Remote access.

The ability to remotely access any recordings is also crucial because we find that most managers are off site and data centers tend to be lightly manned.

Conclusion.

In conclusion Data centers are growing at an incredible rate in the UK and IP CCTV is going to be used more and more for the protection of the building and storage infrastructure. If you require more information please click here.

Manned guard v CCTV

Fraught with pitfalls, remote monitoring of car dealerships has long been debated as to its cost effectiveness. However the cost comparisons against damage and loss always seem to add up in favour of a CCTV solution. For instance it can cost as little as £4000 per annum to monitor a reasonable size car forecourt and its associated compound . An on site security guard could cost as much as £50,000 p.a to provide the same service .

Cost of CCTV

Of course you have the capital cost of the CCTV equipment , certainly not a small investment by any stretch of the imagination. However once you have taken that step you will always  have a security infrastructure and this should never be underestimated . Its pure visual presence will always be a deterrent. Certainly better that a sleeping security guard when it comes to putting off the criminal. In  fairness what can a security guard actually do without the help of  CCTV? Without some kind of camera network he does not have the tools to look after the premises, after all he cannot be looking in all directions at the same the time. So you may as well get that CCTV remotely monitored.

Manned guarding , the choice

The problems of Manned guarding  can be summed up as follows. He can be taken out , bribed or even asleep and most incidents that occur when a guard is on site are “never Seen”. We would however never disregard the benefits of a guard on site but would have to point out that guards tend to be employed retrospectively in response to a specific incident that has occurred on a site rather than as a long term permanent solution.

The Integrated CCTV solution

Now broadband is a feature that most garages and car dealers possess  there is no longer the need for ISDN lines to transmit pictures to your central station . CCTV integrated to hybrid DVR’s that can easily transmit to the control centre and once criminal activity is confirmed by a remote central station operator then a guard response can easily be co ordinated to ensure any crime is stopped at a minimal cost to the car dealer. All sorts of camera  and integrated solutions are available .The Metal mickey and Predator camera range offer vandal proof solutions and Panasonic, or Honeywell IP external domes are another way forward. IP is almost always the best way forward now as it future proofs any solution the car dealer may wish to consider installing.

Use existing CCTV cameras.

However never rule out a hybrid solution, using legacy CCTV equipment integrated to codecs enables us to offer CCTV analytics and IP compatibility. The options now are endless and without doubt very much cheaper than a manned guarding solution. When you work out the cost over a 5 year period then expect to pay only 30% for an integrated CCTV security solution against manned guarding.

HD CCTV for quality images.

IP CCTV in the new HD format will give quality images that could only have been a pipe dream before and the Manned guard solution to site security will become a less and less common feature. The picture quality is stunning and a demonstration is a must to prove this.

Conclusion.

We have been through a period where car dealers, garden centres, scrap yards logistic companies and in fact any one who needs external security have had some good and bad experiences with remote monitoring. It has always been recognised as cheaper but not necessarily better. But now with the advent of broadband IP cameras and most importantly HD CCTV the balance is swinging very much in favour of the remotely monitored IP CCTV solution.



Why VMS ?

There are many benefits being touted about Video sphere VMS software.The main one we can see is the ability to support so many applications and be so flexible when trying to design a hybrid CCTV system.

The framework to have a scalable IP CCTV solution.

Video sphere can support small, medium and large applications that need IP CCTV solutions but need to consider legacy analogue devices . By using codecs all analogue camera equipment can be converted to IP CCTV cameras and integrated into the VMS framework. Video streaming of high frame rates up to 256 IP or converted analogue cameras per server. Ultimately by correctly configuring the network servers VMS can support thousands of cameras across a company group.

MPEG4 and H.264.

Both the above video compression formats are supported by VMS as is multiple PTZ IP cameras and video sphere HD IP solutions. As we mentioned before codecs in the form of Edge encoders are used to introduce analogue cameras in to the overall solution and this then enables existing equipment to run analytics that make these cameras intelligent this has to be considered a valuable upgrade benefit.

Alarm switching.

An important part of all IP solutions is the ability to support alarm switching to follow analytic generated alarms. VMS does this and can also be integrated to data sources such as ATM and POS transactions.

Conclusion.

VMS is a powerful piece of software , designed to be future proofed and has many features and benefits that will suit designers of IP camera solutions and integrated CCTV. It does need a robust server to work in unison with it that can back up recorded images effectively and this does add to the cost. However VMS does offer the maximum flexibility and has many benefits over black box solutions that ultimately will become a thing of the past over time.
