IP cameras and online security

November 21st, 2014 by Frank Crouwel

Today’s story of a Russian website showing UK companies’ and people’s personal cameras, see http://www.bbc.co.uk/news/technology-30121159, shows how important it is to secure access to your cameras. Not protecting access to your cameras is like leaving the door of your house open. At some point you will get unwanted visitors. There is no need for this risk, keeping safe is easy. Just follow the basic rules:

The phenomenon of Viewer Creep in IP video systems

October 21st, 2014 by Frank Crouwel

Photo of Frank Crouwel, Managing Director of NW Systems GroupA well-known form of ‘Creep’ many of you will have heard of is Mission Creep linked to humanitarian interventions in war-torn countries which escalate into, initially unintended, long-lasting military campaigns.

In the world of software coding, programmers talk about Feature Creep as system features or capabilities are extended mid-way through projects. Meanwhile, project managers frequently bemoan Scope Creep, the process by which a project grows beyond its originally anticipated size or complexity.

Axis launch own mobile app for Axis Camera Companion

September 29th, 2014 by Jessica Brooks

Axis Camera Companion mobile appWith quick and easy access to IP video systems from mobile devices being ever more important, Axis has launched its own mobile app for Axis Camera Companion (ACC).  Mobile surveillance apps allow access to an IP video system using the internet, and provide handy remote live viewing and management of recorded video whilst away from a site. Until now, only third party mobile apps were available to access Axis cameras, but this is no longer the case…

HOWTO add your network camera to Internet Explorer’s Compatibility View

April 22nd, 2014 by Kevin Bowyer

Recent changes to Microsoft’s browsers have made viewing and configuring IP cameras that use ActiveX more difficult. Whilst adding a camera into a video recording and management system gets around these issues in some situations (though it’s rare to do this before a camera is even installed in its final location), many prefer and some are required to use a browser to pre-configure cameras for, at the very least, checking the live view and adding IP address settings, but similarly for many other settings as and when necessary.

Let’s take a look at how to set up Internet Explorer to allow ActiveX controls again. This should work for all IP cameras of any brand. If you are logged into your camera in IE and see nothing, this will most likely work for you. [Updated below for Windows 10]

Useful frame rate comparison tool

September 18th, 2013 by Kevin Bowyer

Frame rate comparison toolTo make it easier to understand the visual differences between frame rate options, we thought we’d share this handy video frame rate comparison tool with you, and make it available as a free download.

The tool allows you to easily visualise different frame rates ranging from 1 fps to 30 fps, and how this appears as video footage, and is ideal for helping you decide which frame rate best suits your requirements.

HOWTO use the Focus Assistant on Axis IP Cameras

April 23rd, 2013 by Kevin Bowyer

Axis P1343 Focus AssistantA useful, but often overlooked feature on Axis model network cameras P1311/P1343/P1344/P1346/P1347  is the Focus Assistant. Focusing security cameras via the lens levers can be a tricky business and any installer welcomes a neat trick or device that makes this vital step of the installation process easier and more accurate.

Using this tool it is possible to focus the camera accurately without looking at the video image output from the camera, but to adjust the focus and get visual feedback from the camera itself when the view is nearing and has hit that focus sweet spot.

HOWTO set azimuth on a Sony SNC-EP550

February 13th, 2013 by Kevin Bowyer

Sony SNC-EP550 azimuth settingA useful and unique feature on Sony’s keenly priced HD PTZ dome the SNC-EP550 is its azimuth, or ‘compass point’ setting. This howto also applies to other PTZ cameras in Sony’s latest range.

Calibrating the camera’s azimuth allows you to display the camera’s compass point orientation on the on-screen display (OSD) via the camera’s ‘superimpose’ setting. This can be especially handy for anyone orienting the view against a map or a set of site drawings.

The process to set azimuth is very simple:

What’s IPv6 and Why Should I Care?

January 12th, 2013 by Kevin Bowyer

World IPv6 logoIPv6 (Internet Protocol version 6) is the latest version of the Internet Protocol – the method by which devices (including those which are available publicly as websites) link together and communicate with each other.  It also enables Smartphones, laptops, tablets and other mobile devices to connect to Wi-Fi hotspots and use mobile data. That little router blinking in the corner of your living room supplied by your Internet Service Provider (ISP) wouldn’t connect to the ISP exchange circuits without using the Internet Protocol.

2013 is likely to be the biggest year yet in the switch to IPv6 for homes, business and internet providers alike.

Top 5 most frequently asked technical questions about network cameras

December 17th, 2012 by Raymond Crawford

Our technical team get asked the same questions a lot and so we’ve let one of them loose on this blog to tell us which ones. Over to Raymond…

We receive many queries on the technical support line here at NW, and of course they do vary widely, from customers looking for advice or technical help, right through to providing support for full security systems installations and integrations.

We do, however, answer certain questions more often than others. In fact, I would say that the majority of technical support questions would fall into a handful of issues.

In this blog I will outline five of the issues we most commonly see and provide a link or a brief guide on each so we here on technical support can spend more time discussing Star Trek!

HOWTO: Install Axis Media Control / ActiveX in Internet Explorer

November 14th, 2012 by Kevin Bowyer

As development in IP camera technology progresses most camera manufacturers look to support both a wide range of integration and recording platforms and, in most cases, a wide range of web browsers in order that their cameras can be set up, configured and viewed over the network.

In the case of browsers, inherent limitations still mean that certain functions must be accessible or controlled through a browser add-on – a small plugin, usually downloaded from the camera itself, which extends the capabilities of the browser. Some manufacturers have done away with this in order that their products are supported similarly in all browsers. Some have no full cross-browser support of any kind (products from Taiwanese manufacturer ACTi for instance) and require the use of Internet Explorer and an ActiveX plugin.
