Some Thoughts on Security
With the widespread adoption of Wireless technology (WiFi) there are numerous peripherals that can be combined to make a flexible security systems. For example take a wireless router (no need to put it on the web, we are just using the wireless connectivity), a number of IP cameras (these are self powered with built in web servers) and any number of the new low cost tablet devices (Binatone is bringing one out at just over £100).
The low cost tablets all have WiFi connectivity with built in web browsers and can access the web servers in the cameras from anywhere in your building.
So you with each component costing around £100, you can monitor your entry door, office and four rooms for less than £1000 with minimal cabling to be run. As everything is wireless, the only connection required is power.
The cameras have a built-in SD card slot for recording still images and video. These images/videos can be recorded automatically when motion is detected or recording can be activated remotely. Recordings can then be sent via email, so the cameras can handle a passive security monitoring role out of hours, completely unattended. This could have been profoundly useful where we are based in Shropshire, there having been a recent spate of nursery burglaries.
The scope of such a system can be expanded to as large as needed, by using a private IP address range and paswords the security camera network can be kept secure from the outside. Similarly a secure gateway can be provided via DSL or other Broadband internet connection to offer remote monitoring access.

Acer Veriton Z280G All in One Desktop
Looking to add some technology(ICT) into Pre-School rooms you could do a lot worse than the Acer Z280G. The compact form factor means it will fit almost anywhere and being an all in one you have less cables to hide. With an 18.5~ screen the Z280 provides a big enough viewing area for a group of children to work on. It has a useful 160GB hard drive and comes with Windows Vista. In keeping with the easy to connect and few cables it also has wireless networking. The system is powered by an Intel Atom processor, but with 2GB of memory offers plenty of performance for the type of 'edutainment' titles to be found in a nursery pre-school. Best thing of a though is the price of around £320. Good value, well built and stylish.
