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.

Internet CCTV boosted by Faster Broadband Speeds

Monday, December 15th, 2008

Virgin 50Mbps InternetInternet CCTV is in great demand, CCTV system owners want remote access to their security cameras.

Virgin’s announcement today of their new 50Mbps internet service to the home marks a milestone in the development of internet connectivity and speed.

People want to be able to monitor:

  • CCTV at their office from home
  • their holiday home CCTV from anywhere
  • their home CCTV when away
  • CCTV at multiple business sites
  • In fact CCTV any place from anywhere
  • And then, check their CCTV from their iPhone, Blackberry, Windows mobile ….

In the early days of the internet we all used dial-up telephone internet connections with a connection speed of 56 kbps (kilobits per second).

In those days you may recall that a picture on a web page used to build in a series of horizontal stripes as the image data was downloaded to your PC from the website’s server. To build a single static picture might have taken several seconds …

When ‘Broadband’ first became available our download speed typically increased ten-fold to 512kbps.

Before too much longer 2Mbps (Mega bits per second) was common place.

Followed by offers of 8, 10, 17 & 20 Mbps …

Today, Virgin Media are announcing the roll-out of their 50Mbps internet connection speed to the home.

Virgin have a pre-existing fibre-optic network to street cabinets which enables them to provide this class-leading speed. From their site:

There are now two main types of broadband. One uses copper phone wire; one uses fibre optics. One was invented in the 1870s for phone calls; one was designed for the Internet. One is struggling to keep up with the growth of the web… the other is from Virgin Media.
There is only one fibre optic network. It’s the Mother of all Broadband.

BT will not be out-performed and they have their own plans in-hand to install fibre networks that will allow them to catch up with Virgin’s offer.

The main driver for the demand in increased internet speed performance is the number of home PC users who are now using their internet connections to stream video from services such as the BBC’s iPlayer – their phenomenally successful service which allows you a second chance to see your favourite TV programmes online.

BT, ITV and the BBC are teaming-up to offer some competition to Virgin.

IP Video needs a fast internet connection to stream video smoothly, and to get the data onto your PC before your player runs out of playback data.

The Virgin offer is potentially available to 12.6 million UK homes, and Virgin are aiming to complete their upgrade rollout by Summer 2009.

The service is still asymmetric, that’s to say it has a faster download speed than upload. It’s important to bear this in mind for remote CCTV applications – as your CCTV system is effectively serving images ‘up’ to the internet it is the upload speed which is the bottleneck. With this new 50Mbps service Virgin have increased the maximum upload speed to a class-leading 1.5Mbps which will prove a real benefit if you can get (afford?) this service at your CCTV site.

This competition for ever faster broadband connection speeds is great news for internet CCTV – it is essentially the same thing – video over the internet OR IP Video (IP = Internet Protocol).

As internet speeds increase, and performance improves, connecting to remote devices (anywhere in the world) will simply become a given.

A fast internet will allow the World to become one large network, and you will be able to use-IP to connect to any media, place, device or service.

CCTV and IP Integration Workshop – 5th November, Earls Court

Thursday, September 11th, 2008

CCTV and IP integration workshop – the day before the “Next Generation CCTV” conference.

I posted on Tuesday about the upcoming conference, but nearly overlooked the workshop planned for the day before. I suspect that for some people this may prove even more useful than the conference itself.

Sessions scheduled on the agenda include:

  • Fundamentals of IP Technology
  • IP or not IP – why make the investment?
  • Jargon busting – understanding the technical complexities of IP CCTV
  • Integrating IP with existing CCTV systems
  • Navigating and overcoming technical disadvantages of IP: an honest evaluation
  • Matching the right IP solution to your business / organisation requirements
  • A step-by-step practical guide to IP/CCTV implementation
  • Q&A sessions with open audience discussion

Some good topics there, presenting a great learning opportunity for those that attend.

BBC & NBC Olympic TV Coverage is Video Over IP In Action

Monday, August 18th, 2008

All that Olympic TV coverage that you’ve been watching in HD quality with Dolby 5.1 surround sound made its way back to the UK / USA via IP networks:

In order to bring these signals back to the UK the BBC will employ more than 200Mb/s of fully redundant international fibre capacity, travelling multiples routes around the globe between Beijing and London. These digital links are supplied by the EBU and also provide voice and data communications between London and Beijing and include the 16 channels of video over IP streaming for the remote logging operation in London.
