HD security cameras – HiDef or Megapixel ?

Posted on by

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!

Why buy IP CCTV Cameras?

Posted on by

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?

Outreach Max/Lite

Posted on by

Going beyond the 100 meter mark.

With IP CCTV becoming ever more popular, some camera installers are finding a need to extend Ethernet networks beyond the standard 100 metre or 328ft range.

Bigger IP camera installations.

As installations become bigger and external compound security requires longer cable runs, Outreach have come up with a solution. If you install the Outreach Max every 100meters then full capacity 100base tx or 10 base-t can be maintained across the entire network the device can give 70 watts POE forwarding depending on the standard with a maximum of 0.7 amps on data pairs and 1.5 amps on spare pairs.

Makes things easier.

A big help when specifying installations knowing that it is now very easy to extend the distances we can put the cameras away from the POE source.

360 Vision Technology tell us how IP CCTV will develop in the future.

360 Vision Technology Review.

One the things we were hoping to achieve at IFSEC this year was to get some feedback from the exhibitors and leading manufacturers on the future of IP CCTV and what it holds for installers and end users alike.

Mark Rees is the regional sales director of 360 vision technology. He has been associated with the security industry for over 20 years. So Integrated CCTV took the opportunity to ask Mark some questions about how he sees the CCTV industry developing over the next 5 years , what we all have have in store and what IP cameras and megapixel camera solutions will mean for all of us in the future.

The interview.


Mark, what do you see as the most important product to have effected our industry in the last 10years?

“Probably the DVR……….it allowed high quality images to be stored in a way that did not degrade over time (as with tape) but fundamentally, it allowed individual scheduling of cameras based on priority….this is important when the application requires a mixture of static and PTZ/Dome cameras because additional ips may be required for the moving cameras in order to produce meaningful recorded data………plus, we are seeing the importance of DVR/NVR capabilities in other areas of the system such as PTZ control, remote diagnostics/maintenance and also video intelligence through analytics, all of which benefit and enhance the products we make”.

When it comes to product development do 360 vision lead or do they prefer to follow the market trends?

“Probably a bit of both!!! We developed the worlds first truly serviceable product (Clip2Fit) with our dome products…….this completely changed the perception of customers and end users alike in that we wanted to empower the installer with the ability to repair or maintain PTZ dome products right out there in the field……something that previously (even for us) meant a return to factory scenario………… we have followed that philosophy even through to 2010 where our dome remains still the only truly installer repairable product in the industry……. but in other areas, I guess we monitor the market, spot the trends and with us having our own in-house Design, Software, Production and Technical staff, we can very quickly bring a ‘trend’ product to market, often with the ‘360 twist’ !!! an example is our newly launched Vision IRDome……. answering the common problem of IR requirements on PTZ Domes, we haven’t launched the first IR Dome, but we have put over 20+ years of Dome manufacturing experience and knowledge into manufacturing a great product that is backed with our quality and reliability standards”.

How has the downturn focused your strategy over the last two years?

“We have taken our core strategy, Customer Service, and really pushed that through our customer base………..when times are tough, it is not always about the cheapest price but bottom line profit and customers enjoy the ‘extras’ we can provide that effectively add the few extra digits on the bottom line…………we actually took on additional Technical Staff to answer the need for commissioning and training that we offer, as well as providing future assistance for the new products we are launching……… we are lucky in that, as a privately owned UK based manufacturer, everything was under our own control and we have emerged probably stronger and more efficient than when we entered the recession.”

What sort of growth do you expect to see as we emerge from these difficult times  ?

“Believe it or not, we still saw double digit growth through 2009/10 which I think is testament to the strength and quality of our products and services…………with new products launching (and they are the best products we have ever produced!) then we have high hopes of replicating that feat for 2010/11”

Is the inevitable move to  IP camera solutions  good for our industry or is it just playing into the hands of the big IT integrators?

“I think that is a question for the installation industry really…………..we see smart, switched on independent installers either re-training in IT or employing IT specialists and these installers will always be favourable to win Security Projects than an IT organisation that is entering into the Security Industry………… I also think that Manufacturers and Suppliers need to take responsibility to ensure that training and support is paramount in the transition to IP…..which is inevitable” !

The predator camera has taken off in a big way …you must be very proud and pleased…..? did you have personnel input into the development of the product?

“I wish I could take some credit on this one, because it is simply the best product we have ever made! However, no, our MD, Phil Burton, locked himself away for around 6 months and brought this product to life……….we launched the product back in January and so far we have had wonderful success with it……….helped by very low lead times to supply and also UK support and back up” !!

Megapixel or HD or is it going to be both?

“My personal opinion is that HD would be the best way to gain volume acceptance because people ‘get’ the concept of HD through the domestic market i.e. Sky HD, HD Ready TV’s etc…….. mention megapixel and most people mist over as they comprehend the myriad of megapixel digits and options………… plain and simple, high quality images sell systems and if we can produce HD images that are affordable, installable and understandable then I think the transition will happen quicker……… I heard recently about an emerging technology called HDCCTV where HD images are sent over existing coax cable……this is exciting because it means little disruption to existing infrastructure but beneficial enhancements to the system…..end users appreciate upgrades at minimal cost & disruption”!!!

These cameras and the associated storage is still quite expensive do you see prices coming down in the near future?

“Of course…..look at HDD prices alone……problem is, there is a phase out period for manufacturers on current technology before the transition to the new technology……both in terms of support and also stocks….. so, mass production in volume reduces prices once the demand has been created”…….

Will there be any analogue cameras around in 5 years time?

“That question was asked 5 years ago as well!!! I think there will be an analogue presence in part, even if only for service supply, but I really do anticipate ip doing to analogue what dvrs did to vcr’s” !

DVRs have been a big part of 360 vision sales do you see them being replaced by CCTV software solutions in the near future?

“Take a look at most new IP based cameras and you will see some form of on board storage – whether it is an IP camera or encoder, typically support for Compact Flash or SD cards is becoming more and more prevalent……we are embarking on a very exciting project with one of our Technology Partners, March Networks, whereby we are fitting a full hard drive into the camera head ! the camera then becomes both camera and NVR all in one and with mirror/shadow archiving, then the concerns over network failure is taken away, because the camera is the intelligence…………add in analytics and really, all you need is a software front end to draw everything together to view and control”…………

How did your association with March Networks come about will it help you increase sales both here and abroad?

“Some years back, I met with their UK Sales guy who wanted to integrate one of our domes into their analogue DVR………we spent some time with their Technical guys and vice versa and it was quickly apparent that both companies could benefit from each others strengths and products…..we are both customer and supplier to each other! It has meant that new exciting products can be developed that utilise both companies skills and that offers the installer some major unique products to go to market with (such as the HD Predator seen at IFSEC)”

Analytics….your thoughts on generating alarms to central stations using this technology?

“Analytics are becoming more powerful and accurate – the autotracking analytic that March Networks have developed for our Predator and Dome products is amazing and really shows where the benefit is to the end user operator…….for central stations, to be presented with the live footage of a camera automatically tracking something or someone is very powerful, it leaves the central station operative with a pair of hands to engage audio challenges, telephone assistance and any other activity that would normally be paused whilst he/she moves the remote PTZ camera around……… I still think analytics should be complementary though in an alarmed environment……..utilising analytics and physical alarms can allow for ‘double knock’ safety and reliability”.

Where do you want 360 vision to be in 5 years time?

“Looking back at the last 5 years probably gives an insight into the direction we are heading……….with a great in-house team combined with great Technology partners, then I would like to think that we would be enhancing existing technologies and continually developing technologies for the future………..and still having fun”!

Conclusion.

Integrated CCTV would like to thank Mark for his time and insight, a very interesting look into the future and how the IP CCTV market place will develop. From what we have just heard it is very apparent 360 vision technology will be at the forefront of IP CCTV and innovation for many years to come.

IP CCTV leads the way at IFSEC but did you read the small print?

Posted on by

Reviews all week.

As we go through the week we will be looking at the manufacturers and suppliers that caught our eye at IFSEC this year. Today however we focus on IFSEC itself and how our day went.

Getting there.

It was a bit of an early start, the traffic on the way down to the NEC was  light and we made easy going of it. We arrived full of enthusiasm about what we might see at the exhibition this year and had mentally planned our route round some of the stands we wanted to visit.

Getting in.

The automated check in went like a dream.  We walked into the main hall looked around , got our bearings and then checked the exhibitors map we had been provided with. Here though we had a problem!! I had a bit of a laugh as my colleague struggled to read the stand numbers on the map, no matter what distance from his eyes he tried to hold  the floor plan, he said  it was illegible. He then challenged me to try to read the “small Print” and very quickly I had the smile wiped off my face as I realized that I could not read it either. Were we both getting short sited?? Feedback to the organizers published here .

Arecont IP camera.

Not to be deterred by the fact that we had no idea where we were going we made our way into the show. We chose Arecont as our first stop. The main reason for this is we were looking for a megapixel camera that performed well in challenging light conditions. Arecont have just such a camera. The Av10005 1o megapixel 1080p. They use very clever ways of  getting it to perform at night, this is known as binning. When the camera senses low light it changes mode to allow it to use 4 pixels instead of 1,  to increase the amount of light onto the camera chip. We left very impressed. More on this soon.

Dallmeier.

We then moved on to the Dallmeier stand to take a look at their new video Netbox. Dallmeier have always produced quality goods and the build quality of the Netbox was certainly robust. This one box solution is a hybrid unit aimed to bridge the analogue IP gap and is very flexible. It would be very suited to temporary installations or construction sites. We were also eager to learn that Dallmeier has released Pview 7. This is their main software integration package full of new features. Again we left the stand impressed.

Avigilon.

Avigilon was next. Their range of high definition surveillance systems had attracted our attention. Lots to look at here but the most impressive part for us was the build quality of their Megapixel cameras. No plastic here, the cameras were solid, heavy and extremely well put together. The picture quality was equally impressive especially from the 16 megapixel version.

360 vision technology.

We had heard that 360 vision technology had released a new dome for the show and we were not to be disappointed. A very enthusiastic member of the team demonstrated their new IR dome. It has all the features you would expect and night time vision of up to 100m is very impressive. Light being generated from the strategically mounted IR leds ensures nothing is missed by this brilliantly designed camera. This dome is a different animal though from the 360 dome we have been used to. It is heavier and much more robust. Something we look forward to testing.

March Networks.

March networks were demonstrating the Predator camera or is it the Shield? However it is branded this camera stands out from just about everything else at the show. The auto tracking had been set up brilliantly and you could view the meta data as it followed people around the show .The accuracy was stunning . This camera has just about everything you could wish for and the Predator will be coming out in lots of different versions in the near future. We will be doing a special feature on it later in the month, keep watching.

The best of the rest.

Time was moving on and we still had plenty to see. We paid various visits to Samsung, Redvision, ACTi, Emizon and Paxton. All very interesting and each will be reviewed later in the month.

Home.

Well it was time to go , the overall feeling was one of enthusiastic excitement. All the people we saw had something new to offer and it is blatantly apparent that analogue CCTV is very shortly about to become condemned to the history books.  Standard IP cameras  are starting to look dated with all the emphasis at the show on HD and Megapixel. As the number of pixels and picture quality increase in the cameras the frame rates they can deliver decreases dramatically. In addition the storage required can be prohibitive. Neither of these problems though are insurmountable and in a very short space of time the quality we will see from IP CCTV is going to leave the end user in a position where hopefully they are left with little choice but to upgrade. The future looks bright.
