Recording at the edge – A new approach to surveillance system design

February 26th, 2010 by James Drinkwater


Edge recording is a term which is has started to populate through the IP camera industry with regards to network video recording. Edge recording is a network configuration designed to reduce the bottlenecks inherent to centralized video systems. This article describes how edge recording functions work and describes the pros and cons of its use. Read more >>

Digital Pan, Tilt and Zoom Cameras: Can they compete with conventional cameras?

February 19th, 2010 by James Drinkwater

With the increase in megapixel and HD cameras, more and more camera manufacturers are offering digital pan, tilt and zoom (PTZ) features as an alternative to conventional mechanical pan, tilt and zoom. Can digital pan, tilt and zoom cameras offer the same level of functionality when used in security scenarios?


What is a Network Port and why do I need one?

February 17th, 2010 by James Drinkwater

Network Ports can often be a difficult concept to understand. When working with IP cameras you don’t really need to worry about them until you have to set up remote access. Routers rely on ports to limit data which can access your camera and differentiate between multiple devices. Believe it or not, you are using a port just now, only you can’t see it.


HOWTO: IP Camera Remote Access

February 16th, 2010 by James Drinkwater

Remote access is often a key factor when choosing a security camera. The ability to monitor a location remotely is a huge benefit for most and is often the main reason for selecting an IP camera.

However, the act of setting up remote access can often be very confusing for non-technical users and can lead to difficulty. The process is actually very simple but does require some explanation.


UPnP: Friend or Foe?

February 8th, 2010 by James Drinkwater

We get a lot of technical support requests regarding Port Forwarding, the process of allowing access through the firewall on your router to your camera so that you can access your camera from across the Internet. It’s a tricky process which can leave many novice users scratching their heads. Read more >>

HOWTO Set up a personal FTP server for use with an IP camera’s image transfer function

May 1st, 2009 by Greg Innes

With the image transfer feature found in many IP cameras you can store a number of images in a central location as an archive for security purposes or maybe for building a time-lapse movie.

These images are sent using the FTP protocol which stands for File Transfer Protocol and is normally associated with transferring files across the Internet. It also works equally as well on a local network and this guide will show you how to set it up.


Using H.264 video compression in IP video surveillance systems

April 3rd, 2009 by Greg Innes


H.264 is an open video compression standard. Uniquely, H.264 is the first compression format to be formed by collaboration between members of both the IT and telecommunications industries and each have their own name for it. H.264 is the name used by the ITU-T (International Telecommunication Union) and MPEG-4 Part 10 AVC (Advanced Video Coding) is the name used by the ISO (International Organization for Standardization). The video surveillance industry has adopted the term H.264 and this has become the primary reference to the standard. This is also the term we use.

H.264 is fast becoming the standard video compression format for the video surveillance world and if we look at the claims it makes we can see why. We hear bold statements about low bandwidth usage, reduced storage requirements, higher resolution monitoring and better quality images and it all sounds too good to be true… doesn’t it?


What is an IP camera?

June 17th, 2008 by Greg Innes

Sony IP cameraIP cameras are known by many different names such as IP camera, network camera, IP network camera, Internet camera, network webcam, and so on but they all refer to the same item: An IP video device which which can deliver live images over IP-based networks such as a Local Area Network (LAN) or the Internet.

Stand-alone device

The IP camera is a stand-alone network device which can operate without the support of a PC. This means the camera does not rely on software from a PC to help it produce images in the same way a USB web cam would, but instead the IP camera can be connected to a local network based in any home or business and deliver images to any connected PC be it at the same location or half-way round the world across the internet. IP cameras come with a wide variety of features such as fixed lenses, pan-tilt-zoom control, endless 360 degree panning, indoor or outdoor use, 2-way audio, infrared illumination, intelligent video analytics etc. There’s always a camera to suit your needs.

Benefits of IP video

Flexible and powerful, IP video provides many advanced features not found in traditional analog CCTV systems making it ideal for video survelliance, monitoring and recording. Examples of advanced features include remote access from anywhere in the world, motion/audio detection, object detection, people counting, image upload by FTP, alarm notifications by email or SMS text messaging, true digital recording to dedicated recording devices or to hard disks on local PCs or across the Internet, and many more features which enhances the level of protection you can offer your property or business and its personel.

Many IP cameras also now include Power over Ethernet (PoE) technology which allows the camera to be powered using the same Ethernet cable as the data. This simplifies installation and allows a camera to be placed at a location where there is no convential means of power.


Panasonic IP cameraSecurity is but one of the many uses for IP cameras. Some other applications include health & safety, retail marketing, remote management of construction projects, web attraction for leisure and tourism industries or keeping an eye on loved ones or pets…

Top 5 Home Security IP Cameras for Mac Users

May 22nd, 2008 by Greg Innes

As any Mac user will tell you they generally get stuffed when it comes to software availability and support for their machines. Sadly when it comes to IP cameras it’s no different.

As IP video specialists it probably won’t come as any surprise that we’ve seen a one or two IP cameras in our time but luckily we also have someone who owns a Mac (yes just the one!). So here is our top 5 list of cameras which we think make ideal home security cameras for Mac users. Read more >>

HOWTO: Prevent Wireless Interference

May 9th, 2008 by Greg Innes

Prevent wireless InterferenceMaking the transition from wired to wireless is an exciting step and with a wide choice of wireless IP cameras now available on the market you can keep an eye on your home or business without cluttering it up with cables.

Normally wireless connections are every bit as reliable as their wired counterpart but sometimes there can be something which prevents their smooth operation. Interference.


We’ve all experienced interference in some way, from the television picture breaking up during a heavy storm or crackling on the radio when you enter a built-up area or valley. Your wireless signal works very much in the same way as your radio or television and may dip in and out depending on circumstances and the environment.

We realise that when you are connecting your IP cameras wirelessly is it even more crucial that they remain connected at all times, especially when they are used as IP security cameras. So let’s take a look at some of the causes of interference and how we can help reduce their effect. Read more >>
