IPCCTV over WIFI

CCTV over Wifi……saving cash on analogue RF !

The scenario.

Picture the scene (pardon the CCTV pun!)

Building A is 500 metres from building B

There are 4 cameras on building A, one on each corner (don’t you just love perfect worlds!) and they need to be viewed, recorded and controlled (did I mention they were PTZ?) all from building B

THE PROBLEM

The two buildings are separated by a river – a very nice river, big boats coming up and down, delivering stuff to dockside delivery points.

No chance of cabling then….. Until recently, the answer was to use free range wireless transmission solutions, such as RF, Microwave, Laser etc……… but, history shows that each has it’s positives and negatives but they all share one common negative….. expense.

ANOTHER WAY?

With the upsurge in IP, there is another way………..Wifi…………ok, professional wireless is what all the proper ‘wifi’ consultants will call it, but wifi nonetheless.

You see, Wifi does not have to be a one to one transmission solution…………. with typical bandwidth of 54Mbps, even if we halve it (because clever network guys will tell you that there is always a drop over distance etc), we can expect a 27Mbps bandwidth allowance……

So, take our building A and B scenario…. cable all the 4 cameras to a central point (it is a perfect world after all !) and either convert to IP from analogue using encoders (or, if we are to get this industry into the 21st century let’s push the boat out and go true IP cameras!) and connect to a regular 4 port network switch…

Take the output of that switch and insert into something like the Silvernet product range….. 1Km line of sight, pre-configured to create a point to point connection…..go to building B, position the receiving unit line of sight to building A and either decode back to analogue or bring one, neat, simple CAT5/6 cable out and introduce to the network for full control and view of the system ! simples !

THE THEORY AND THE PRACTICE

Ok, we don’t always have a perfect world, clearly, however, using the above solution, we have sent 4 cameras over the one link….saving a LOT of money:-

RF/Microwave/Laser = at least £2000+ for EACH camera

WIFI = under £1000 for a 1Km link with the ability to run a good few cameras – typically a PTZ IP camera would be around 5Mbs and a static at around 2Mbs

But, just like RF/Microwave/Laser, if the Wifi states ‘Line of Sight’ or LoS, then it REALLY means that…..so much as a leaf on a overhanging tree, or, in the case of our River separating the two buildings, boats that might momentarily ‘interrupt’ the signal, it is imperative to ensure that the TX and RX units are positioned so as to enjoy clear and uninterrupted transmission!

The cost savings are impressive and just might give this industry the excuse to use IP !!

HD security cameras – HiDef or Megapixel ?

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!

Hybrid CCTV camera solutions. The way forward!

CCTV what’s next?

In today’s market it cannot be denied that the whole ethos of security and ideas of how customers protect their premises is changing. Many companies are looking to recycle existing security equipment or at the very least their current wiring  infrastructure. New equipment sales and complete upgrades are becoming more difficult to sell as budgets are tightened across all areas of business. Some security companies view this as a depressing fact and have resigned themselves to less sales cutting their staff accordingly. This may however be a little premature.

CCTV servicing.

Service opportunities are rising as existing kit slowly begins to fail and begs to be replaced but a whole new system is often a luxury that many companies just will not stomach. So it is now the time to think smart. Networks and IT technology is a an unstoppable fact of life and upgrades in this area are inevitable so camera solutions have to fit into this ever expanding frame work . The whole situation lends itself perfectly to a hybrid solution.

What is a hybrid solution?

Well a hybrid DVR is simply one that can handle both old analogue technology and the new IP cameras that are seen as the future of CCTV and security. Phasing IP in is less costly but still allows an end user to embrace the new products that can bring extensive benefits. The only proviso being, that the IP cameras  must be specified correctly. The right camera for the right application.

Hybrid CCTV systems.

Forward thinking Installing Companies prepared to use old analogue cameras together with a hybrid DVR will find the first step to new on going sales has been reached. As Hd and Megapixel cameras become more and more prevalent they can be integrated into a hybrid system over a period of time. This is more in the thinking of company accountants looking to find a solution, but one that suits his needs and budgets.

Be flexible, service all the  security solutions on a site!

To grow sales be flexible. Take on one or more of the security disciplines on site. Then, a customer will be more reliant on their installer and again this will give an opportunity for more sales and even integration between the CCTV, access control and intruder panels.

Sales to increase?

So lets not be gloomy about how we can grow sales of megapixel, HD, IP cameras and DVRs. This particular period  of difficult market conditions should really be re-thought as a chance for innovative and forward thinking installers to grow and enjoy the bright future that new IP camera solutions will soon bring.

IP camera 200 series from Bosch

Bosch 200 series.

Bosch have recently brought onto the market the new IP 200 series IP camera range. The camera is an IP unit that comes in two versions, the IP camera 225 and the IP camera 255. Essentially the 225 is a fixed lens and the 255 is varifocal . The beauty of the 200 series is that you need no DVR. The camera is a networked solution and has recording ability on board within the camera using a 16 GB  SD card.

Clear crisp images.

The camera produces clear crisp images and all video can also be reviewed over the network using CCTV software that is supplied with the camera. The images are compressed using H.264 and this allows an additional 30% storage capacity over MPEG-4 . Both IP cameras are colour units and are ideally suited to reception areas or tills where they could be used in multi- site applications and accessed by 1 individual responsible for all sites such as car hire franchises or late night stores.

More benefits.

The IP camera 200 series has even more benefits, it is a single box solution and easy to set up. Simply remove the unit from the box, fix in the required position and connect to the network via an IP point. It has built in motion detection and also audio detection. As mentioned before with both on-site or remote viewing via PC and power over Ethernet this is a fantastic solution for those who have a problem on a single area of their site and need a quick easy security answer.

Conclusion.

Very competitively priced and simple, the IP 200 range can fit into many situations and will find many takers, especially for monitoring and recording sensitive areas where a full scale CCTV camera system quite simply is not required.
