Hard Disc Drive Storage for CCTV Surveillance

Saturday, January 10th, 2009

Veracity mentioned this article on their website in an email I received recently; it’s a good write-up on the use of hard disc drives in modern CCTV video storage. The article isn’t new but it provides a lot of useful information and we think it’s worth pointing it out to you:

The most obvious current trend in video surveillance is the slow evolution from analogue cameras to IP cameras. Industry vendors of recording systems appear to be divided into two camps : the sceptics, who are wondering when the IP video revolution is really going to take hold, and the informed, who know it is already here and are just getting on with it.

Although the IP video segment of the UK market is currently only around 15%, it is growing rapidly. In Europe, where analogue CCTV cameras are not so entrenched, the growth rate is even steeper.

One of the things that has held back IP video systems up to now is the lack of any real reason for users to switch, even for new installs. What would they have gained, bar a little increased flexibility ? Now, in 2007, the story is quite different : most well-designed IP cameras are progressive scan, at long last leaving behind the problematic interlaced image legacy of the broadcast TV standard. Further, and more importantly, mega-pixel cameras (with resolutions way beyond HD TV) are now here and affordable. At long last, mega-pixel cameras provide the compelling reason to switch to IP-based systems. The improvement in image quality offered by high-quality mega-pixel cameras in nothing short of dramatic, even breathtaking. Another problem which has held back adoption of IP cameras is the vast amount of legacy co-axial cabling installed in existing systems. However, several vendors are now offering Ethernet over-coax solutions, so this is no longer a barrier at all.

Well worth a read, to aid your understanding of the use of big HDDs, RAID storage and potentially high disk failure rates.

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?

Veracity – truly innovative IP network products

Friday, June 20th, 2008

HGHWIRE co-ax converter pair

Veracity manufacture a range of innovative products which enable you to extend your network reach, use Power Over Ethernet (POE), or utilise pre-existing co-axial CCTV cables for IP networking:

CAMSWITCH – a rugged, 4-port, POE, network switch

HIGHWIRE – enables you to utilise existing co-ax cable as a 100Mbit network for cameras or other IP devices

OUTREACH – stretches your network’s reach in 100m steps (with POE) up to 500m

TIMENET– provides an NTP (Network Time Protocol) device on your network to synchronise your devices

OUTSOURCE – is a POE midspan device to inject power onto your network cables for POE supply to IP devices

OUTBREAK – is a POE splitter, which will separate the power and data cables at the device to allow devices that do not have POE functionality built-in to utilise single cable POE supplies

We have now added the full range of Veracity products into our webshop.
