Until a few years ago internet was transmitted only through cables, you therefore had to be physically connected to the world wide web network to be able to access it. This condition had several drawbacks, for a start you could not access the internet if you where not at home, or in an office etc. An recently the wirless internet has been invented and has emmerged. This system has great succes, especially with smartphones or portable computers. Instead of having a cable which links your computer up, you have a system which emits signals which are recieved by your computers special recepter antenna. And therefore can access the internet in high speed.
This new invention has had for effect to create what are called hot spots, areas where you can acces a wirless connection for free, for example in train stations. And now most cafe’s and bars have wireless connections as well. So you can surf the internet whilst having a coffee or a beer. This is very practical if you want to check out your facebook, or twitter account, or even look up time tables or cinema programs.
This phenomena has enabled several other wirless connection inventions. Such as wirless cameras. Their system works the same way as a wirless internet, they transmit to the central console or monitor and you can then view all the cameras. This is a great invention, saves a lot on installation costs, and they can then be put anywhere. They can also be moved simply to an other location. All you need is to unscrew the fixed camera and move it. Because the cameras are fitted with the latest wireless transmission devices the image viewed on the computer is instant. There is no delay inbetween. The cameras can also be switched of by distance with a simple click. Their is not need for a physical manipulation.
