IP CCTV still just 5% of the CCTV Market?

Friday, December 19th, 2008

Once again this week somebody quoted this statistic:

Of course IP is only 5% of the CCTV Market.

Can that really be so?

If you take a look at our IP CCTV Facts page you’ll see that it’s being adopted by some fairly serious end-users, and used in some fairly big system applications.

You have to wonder whether stats such as these, once created, simply get trotted-out ad infinitum:

  • 4million CCTV cameras in the UK
  • one camera for every 14 people
  • you’ll be caught on CCTV 300 times a day

These numbers have been quoted for about the past five years now!

Who is counting?

How?

Who buys IP CCTV?

Thursday, December 4th, 2008

IP CCTV has been around for a number of years now and it’s interesting to just pause and consider who is committing to it as their chosen surveillance technology.

It’s interesting to note that more and more of the big system users, with the resources to carry out in-depth trials, and the experience of previous technologies are now rolling-out IP CCTV solutions at their sites. IKEA, John Lewis, casinos, shopping centres and ports all feature amongst this set of big customers that have switched to IP CCTV.

In the world of smaller surveillance systems, there are two clear categories of customers that select IP CCTV:

CCTV Upgraders

People who already have traditional analogue CCTV systems and want something better. They’ve had incidents, they’ve reviewed recordings, they would like to be able to ’see more’ next time there’s an incident …

The Tech Savvy

People who ‘get it’ - they have their finger on the pulse of technology, they check lots of websites, they consider and compare different manufacturers, they read the specifications on the datasheets, they understand megapixels, bandwidth, gigabytes and lux levels, they call and discuss their application …

Who doesn’t buy IP CCTV?

Basically, the price conscious consumer. They know (or have been told) that they must have CCTV. They look for the cheapest solution to tick that box, they don’t consider the image quality, they don’t read specifications. They don’t profess to understand analogue or ‘digital’ CCTV. They may have been told (by a friend, or the first installer that they spoke to) that they need a DVR. They are often keen to get the job done, and they just buy cheap.

Of course, these people become the ‘CCTV upgraders’ of the future … because once they have committed to the co-ax cabling and BNC connectors of traditional CCTV they’re not going to be able to do a lot to improve their system by simply changing components, and in due course they are quite likely to upgrade to IP CCTV …

Security system prices rising

Wednesday, December 3rd, 2008

Unfortunately, not much is manufactured in the UK these days (especially not high-tech electronic security equipment).

In recent months you were getting $2 for your £1, you now get $1.475.

One euro used to cost 70p and now costs 86p.

(source www.xe.com noon today)

Messages (warnings) received from manufacturers and distributors in the past few days have carried warnings of price increases of up to 20% for some products!!

Some of these price hikes are scheduled for 1st January 2009.

Manufacturers are recommending that we reduce the validity period for any quotations or proposals that we prepare.

What can you do? Well, it sounds like a terrible cliché, but, if you know what you’ll be needing:

Buy now to beat the price increases!

Security Management Today (SMT) Magazine now online only

Tuesday, December 2nd, 2008

SMT - Security Management Today - Magazine will no longer be available in print.

It’s disappointing to learn this, as it was a stand-out different magazine in the security sector. Most security magazines are aimed at the installers, SMT (as the name suggests) was aimed at Security Managers. I know that many of the Security Managers that I have worked with were on the circulation list and found it a useful source of information.

Its strapline was:

The UK’s No1 for security managers

The magazine now has its own online pages at SMT Online, but I’m not sure that they’re distinct enough from the other information presented at that portal, and in my humble opinion I cannot see security managers visiting those pages in the same way that they liked to turn the paper pages.

Vandal Resistant CCTV cameras not Vandal Proof

Tuesday, October 14th, 2008

Vandal resistant CCTV we can deliver.

Vandal proof is just a promise too far - no sensible CCTV manufacturer or installer would ever offer “vandal-proof” products.

There is no end to the amount of force that might potentially be used.

Some manufacturers will state their claim e.g. “proven to withstand a blow from a 10lb sledge hammer”.

I recall, when vandal-resistant dome cameras first became available (some years ago) one manufacturer had a rig on their exhibition stand that allowed you to lift and drop a hinged sledge hammer repeatedly onto their dome camera’s bubble!

Another manufacturer (or was it the same manufacturer?) made a video of a truck driving over their camera to show that it could survive this extreme treatment.

However, I once attended a client’s site after a vandal had struck a camera mounted to the ceiling of a subway with a five foot concrete fence post - it did not survive that!

The ultimate in this particular game is “ballistically tested” - as you can see from above, nobody will ever claim that they have manufactured a bullet-proof camera!

Helicopter Gunship Attacks Corner Shop!!!

Thursday, July 17th, 2008

Right, now I’ve got your attention:

I see a lot of CCTV systems, can anybody tell me why so many cameras show so much of the sky??

Are they really expecting the above headline?

Did the system owner really ask the installer to monitor the sky?

The challenge for CCTV cameras is to capture useful evidence; as the size of the scene increases, the size of people within that scene decreases, and the usefulness of their images decreases too (bear in mind that Home Office guidelines for CCTV images to be admissible for ‘recognition of a known individual’ require us to capture their image at 50% of screen height).

So why waste valuable field of view on the sky?

To make matters even worse, the sky is often bright - to cope with the brightness of the sky the camera & lens combination will close the lens iris - this then results in what is on the ground being put completely into dim shade, and becoming a virtually useless image.

Tilt the camera down a bit.

Use a vari-focal lens and zoom-in a little; take the sky out of the scene, and fill the field of view with a useful scene.

For goodness sake - think about the image; less is more; just cover an agreed scene and deliver useful images!

Let’s keep the picture in the picture ….!!!

Thursday, May 22nd, 2008

I’ve just read a 25 page guide on IP video from a large network company.

It was a good guide, well written, it provided good explanations on ethernet, IP, POE, cat5/6, etc.

The bizarre thing was, it never once referred to image quality or resolution.

It is all about the image - please keep that in mind!!
