24in widescreen monitor with HDMI

The VX2433wm is a smart-looking display. Its 1,080p resolution and 16:9 aspect ratio matches the shape of a widescreen TV and is ideal for displaying HD content. Finished in a glossy piano black, it has a single silver power button at the front. The remaining controls are tucked out of sight on the right-hand side, keeping the appearance neat and tidy and retaining minimalistic good looks.

Viewsonic’s menu system is not the easiest to navigate. This is partly because the design precludes the use of unsightly button legends.

The menu contains some useful functions, including control over aspect ratio and the ability to turn the dynamic contrast system on or off we prefer to leave it disabled. While this boosts the specified contrast ratio from 1,000:1 to 20,000:1, it’s unhelpful for most applications other than watching video. It also lacks any one-button display presets, such as text, movie or photo modes. This means you’ll have to tweak the individual functions manually.

If you do want to watch video, the display will cope admirably with a variety of sources, thanks to its built-in HDMI connector, which will allow you to hook up a Blu-ray player or games console with a single cable and enjoy 1,080p HD video and sound through a pair of built-in 2W speakers.

You also get DVI and analogue VGA ports, so you can connect up to three devices at once and switch between them from the front panel.

In use, the VX2433wm delivers a bold, sharp picture, thanks to its excellent contrast. However, colour reproduction was less vivid than some of the competition as revealed by our test results.

Overall this is a smart, good-looking display with excellent connectivity and better-than-average performance. Look online for discounted prices of around £200 inc Vat.

Watch free-to-view TV but a rooftop aerial is a must

Hauppauge has expanded its range of portable TV tuners to include the WinTV-Ministick HD, a portable USB-based tuner capable of picking up local free-to-view TV channels, including those in HD.

The device is no bigger than a thumb drive, with an RF port at one end to connect to an aerial. A portable mini-aerial is supplied as is the latest version of WinTV for accessing and recording channels.

Setup is straightforward, provided you have access to a strong signal. During our tests we found the supplied aerial to be all but useless, very occasionally picking up a few channels only to lose them after reconnecting, so we’d strongly advise anyone considering a purchase to use a rooftop aerial.

This restricts its versatility somewhat, but isn’t the only factor that can affect playback.

After successfully scanning for and detecting a range of channels using the setup wizard, we discovered our test notebook was severely under-powered and had to resort to carting a desktop machine to a location close enough to an aerial wall socket.

Reception and picture quality improved dramatically, but the listed system requirements are only a bare minimum, and might not be enough for consistently smooth playback.

WinTV is a basic application that provides all you might need from a TV tuner, such as the ability to pause, time-shift and record programmes. It includes a seven-day electronic programme guide (EPG) and the ability to set up and schedule recordings, show subtitles and Teletext.

Generally we were impressed by the image quality, portability and operation of the Ministick HD, but only in an optimum environment. The potential signal issues are a problem, but this is also true of many other TV tuners. If you have a powerful PC, this is an effective way to access digital television and HD.

Buffalo WZR-HP-G300NH wireless router

Fast speeds when channel bonding, but no 5GHz mode

Buffalo’s latest router is a sleek-looking device, aimed at cable broadband users, since it has no built-in ADSL modem.

It is surprising that the WZR-HP-G300NH doesn’t feature a 5GHz 802.11n mode, relying on the more congested 2.4GHz spectrum only. But we still experienced some decent speeds during testing.

When using the router with Buffalo’s Wireless-N USB adapter, we transferred a 349MB file in 63 seconds, giving a throughput of 44Mbits/sec.

Switching the channel bonding mode on, the same file transferred in just 33 seconds (an impressive 85Mbits/sec), however your neighbours won’t thank you for hogging two wireless channels. These speeds were achieved at close range, and when we moved to around 30m away speeds dropped to under 15Mbits/sec, which is still respectable.

Buffalo has furnished the WZR-HP-G300NH with a few useful extras, including a Bittorrent client that allows for peer-to-peer downloads requiring a PC to be switched on. To use this feature, you will need to attach some form of storage to the USB port at the rear of the router. Once attached, the router will also function as a basic network-attached server (Nas) device.

A switch on the front of the router lets you turn the Movie Engine mode on. Essentially a quality of service (QoS) feature, this prioritises media traffic to reduce the likelihood of video stuttering. However, we had no trouble streaming HD video through the router, whether the setting was enabled or not.

There’s plenty to like about Buffalo’s latest router, but it’s rather disappointing it can’t manage 802.11n on the less-cluttered 5GHz spectrum.

Powertraveller Solar Gorilla portable power charger

An eco-friendly way to charge mobile devices

The Solar Gorilla is a portable solar panel that can charge an MP3 player, mobile phone, or even a laptop.

It’s quite a bulky unit that comprises two photovoltaic panels that open like a clamshell to capture energy from direct sunlight.

You plug a device into either the 5V USB or 20V laptop power using one of the supplied adapters. There are plenty of these for all the shapes and sizes of power connector used by different manufacturers, so you can charge most notebooks, including those from Asus, Acer, Compaq, Gateway, Epson, Samsung, Sony, E-machines, Viewsonic, Dell, Panasonic, but an Apple Macbook needs an adapter.

It doesn’t store any energy, so you can’t rely on the Solar Gorilla as an alternative battery. Instead, to charge a device, you have to leave it plugged in while the Solar Gorilla is in direct sunlight, which restricts when it can be used.

Powertraveller sells another product, the Power Gorilla, a portable battery that can be charged by the Solar Gorilla, although this costs another £130.

If you spend time camping or hiking, the Solar Gorilla could be exactly what you need if you have to be certain your laptop or mobile phone will work away from a power source.

The surface of the Solar Gorilla is covered in rubber, so it can survive a few knocks and scratches if you’re on the move. It’s quite thin, so will easily slip into a laptop bag or a rucksack, but be aware it weighs 700g.

It’s a free source of energy, but it might take a while before the savings to your electricity bill match the initial cost of the device.

The Solar Gorilla is an excellent solar-powered charger, but aside from giving you a warm feeling that your laptop is being powered from a source of eco-friendly energy, it’s only useful in limited situations, most of them travel-related.

Genius G-Shot HD520 HD camcorder

Orestis Bastounis — 2009-07-02T10:25:00.000Z

A portable HD camcorder for less than £100

Like the Flip Mino HD, the G-Shot HD520 is a pocket-sized camcorder that can record 720p resolution video. However, the G-Shot can also capture still images, function as a webcam, MP3 player and ebook reader, has a 2.5in rotatable flip-out LCD and its internal storage can be expanded with SD cards. And, incredibly, it’s much cheaper than the Flip Mino HD.

When recording video the G-Shot is meant to be held with your arm outstretched, pointed like a gun. It isn’t as light or portable as the Flip, measuring 4cm deep at its widest point.

On the right-hand side is a control for 5x digital zoom, along with a button to manually turn the flash on or off when taking still images.

Four buttons sit under your thumb for going through menus, selecting options and deleting files. A switch on the top lets you switch focus settings between normal and macro recording.

Regardless of which macro setting you use, the G-Shot won’t produce brilliant-quality video, thanks to its low-quality lens.

We spent time recording indoors and outside, and both times the results were mediocre. Video was either grainy or blurry, with artefacts obscuring small details, which negates the benefit of recording in high definition. It isn’t terrible though and is perfectly suitable for recording video for the web.

The G-Shot’s other features range from good to useless. The MP3 player works well as expected, but the small 2.5in screen isn’t suited for reading ebooks. Its still images are reasonable, although most dedicated compact cameras produce far better quality.

Still, you’d be hard pressed to find another HD camcorder less than £100. The G-Shot isn’t nearly in the same league as the Everio, and falls short of the Flip Mino HD. However, it’s perfectly suited for recording while on holiday, or for anyone who likes to share online video.

E-Pens Mobile Notes

A quick and easy way to transcribe handwritten notes

Anyone who has attempted to convert a series of handwritten notes to text on a computer knows that transcription can often be a painstaking and time-consuming process, so automating this with a device such as E-pens Mobile Notes could save a lot of hassle.

The package consists of a digital stylus that acts as a regular pen, a receiver unit and conversion software. It can either be used on the move or as a mouse for tablet PCs, or for handwritten text entry into various applications.

Setup is straightforward and, once charged, the receiver can be clipped to the top of a pad of paper, picking up pen strokes to store as one of up to 50 virtual pages.

Once connected to a computer, these can be imported using the supplied software and converted to digital text using optical character recognition, with a range of settings available to denote language, writing style and end-format.

In addition to this, switching to mouse mode means that pen movements control the pointer on screen, with a tap on the page or click of the control button on the pen, activating left and right click.

We were very impressed by the responsiveness of the stylus and receiver and, though you have to write quite neatly to achieve 100 per cent accuracy, it does an admirable job of converting scrawl into text.

If you are unable or unwilling to write neatly, there is a recognition trainer provided to help the software interpret your style of writing, although you will need to proofread and alter text after writing to correct inevitable mistakes.

A bigger issue is that the pen doesn’t feel solid or well-built and is prone to slipping in the hand slightly after extended use. For normal writing, a premium fountain or ballpoint pen is much more satisfying.

However, the Mobile Notes package is still an effective product for saving time when transferring handwritten notes onto a PC.

D-Link NetDefend DFL-260

All in one threat protection for the small business

D-Link’s NetDefend DFL-260 is a UTM (Unified Threat Management) appliance which, at first glance, offers the same firewall/VPN facilities as the cheaper DFL-210 we reviewed back in the September 2007 issue. However, whereas the DFL-210 is very much an entry level product, the new DFL-260 adds anti-virus and more sophisticated intrusion protection options, together with hardware accelerators to cope with much larger networks.

From the outside there’s very little difference, with four 10/100Mbits/sec Ethernet ports for Lan connectivity plus two for the internet. Traffic shaping and failover options are available across the two Wan ports, added to which the second can be used to create a so-called De-Militarized Zone (DMZ), to protect public facing servers.

In terms of the firewall there’s not much difference either, implemented in the NetDefendOS software. To this is then added a VPN server able to support up to 100 tunnels with a maximum throughput overall of 25Mbits/sec. Support for site-to-site and client-based VPN setups is available using a mix of tunnelling IPSec, PPTP and L2TP technologies, but software clients aren’t included.

The “real” UTM options then start with what D-Link calls “stream-based” anti-virus scanning. By this it means the ability to inspect files for viruses as they pass through the gateway, without having to be cached. Kaspersky technology is behind the D-Link anti-virus scanner, added to which there’s an advanced Intrusion Prevention System (IPS) which employs a technology called component-based signature recognition to identify a wide range of potential threats. This, in turn, uses information collected from a number of sites including the US National Vulnerability Database.

The IPS and anti-virus options also benefit from hardware accelerators. D-Link claims the accelerators enable these options to be run simultaneously without degrading firewall/VPN performance and so deliver sufficient throughput to handle networks of 50 users or more.

Web content filtering is yet another option, with 90-days of free updates for this and the other services included. Thereafter, however, annual subscriptions are required which, together, can cost almost as much again as the hardware.

In terms of what it has to offer, then, the DFL-260 looks like it ought to be an effective UTM appliance, well suited to the small business. As with the DFL-210, however, management is something of an Achilles heel

The basics are fine, with a console port for local management via a command line interface plus SNMP support if needed. It’s also possible to connect to the DFL-260 via a browser both for initial deployment and day to day management.

We found the Web interface easy navigate, and there’s a startup wizard to, where for example, you can assign addresses to the various interfaces, set the clock and so on. That done, however, and all you’re left with is a fairly basic firewall. Everything else has to be configured manually, and it’s not easy

Policy-based management is the order of the day, which is good, and once you get to grips with how it all works it’s not hugely difficult. However, you’re presented with a seemingly endless list of options and a high degree of technical knowledge is assumed throughout. Such knowledge is likely to be in short supply in the kind of small businesses at which the product is aimed. The documentation helps, but only a little, leaving the DFL-260 very much the kind of product you’d want a specialist reseller to both install and maintain.

Violet Mir:ror

An RFID kit for home that’s charmingly loopy

The French are experts at creating quirky technology and they don’t come quirkier than Violet’s Mir:ror RFID (Radio Frequency Identification) reader.

The Mir:ror starter kit ships with a Mir:ror USB RFID reader, two nano:ztag miniature RFID rabbits and three RFID ztamp:s adhesive tags to stick on everyday objects. The Mir:ror itself is a small white circular reader with an LED-illuminated rim that glows in several different colours depending on its status. There’s also a small audio beeper in it.

To get started, you create a user account at Violet’s website and download the Mirware application. Once your Mir:ror is connected, you need to assign actions to your RFID-enabled objects by placing one on the reader then registering and naming it either using the Mirware application or directly using your account area on the website.

Each tagged object gets its own unique email address, allowing you to do surreal things such as send emails to your umbrella. It will recognise any ISO-compliant RFID chip, so we could register both an Oyster card and an RFID-enabled Barclaycard as triggers to launch applications.

You can associate any number of applications with each object. There are several general-purpose apps such as ‘launch a program’ or ‘open a URL’ so you don’t need to do any programming to get started.

Available applications include launching a Youtube video, podcasts or RSS news services using text-to-speech conversions. The quality of text-to-speech isn’t brilliant, though. Applications can be chained together. There’s no easy way to create your own applications, but you can use a tag to send metadata to any web-based application.

Mir:ror has some good novelty value and is simple to use, although it’s not yet a must-have product. But as a technology demo, it’s impressive.
