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.

Power Over Ethernet (POE) Explained by Veracity

Tuesday, December 16th, 2008

Power Over Ethernet brings some great additional benefits to the application POE experts Veracityof IP security devices such as network cameras.

Essentially, you can power the camera (or other network device) via the ethernet data cable:

  • a single cost-effective network cable to each device
  • safe low-voltage supply
  • easily extend your network
  • no need for skilled electrical installation labour
  • a single device POE mid-span extension
  • multiple devices via a POE switch
  • the ability to ‘reach’ 100m or more from your existing network
  • 802.3 POE standards allow common solutions for many devices
  • even devices that do not have POE built-in can be used with POE supplies (by use of an Active Splitter at the device end)

We take a lot of calls about the use of POE with IP CCTV and are aware that people find some of the concepts a bit tricky.

Veracity have just produced some really helpful white papers to explain power over ethernet technology and its application:

“Power Without the Struggle” – the benefits of POE technology and how to take full advantage of them …

“POE Explained” – POE concepts through to the latest 802.3at ‘POE Plus’ solutions …

Veracity’s OUTREACH & OUTSOURCE solutions enable you to extend POE beyond 100m.

These new guides from Veracity are written in plain English with helpful graphics and diagrams to aid your understanding. We recommend you take a look.

You can find their range of POE products in our POE shop.

Veracity – truly innovative IP network products

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.
