Everyone in the UK and many other countries around the world has had some experience of CCTV camera systems. Whether this is seeing footage on TV, being captured on camera while walking down the street or around shops, seeing the devices attached to buildings or police vehicles, there is no escaping the prominence of these handy tools.
Indeed, Britons are among the most prolific users of these pieces of equipment and this trend shows no sign of dying down. After all, there are so many potential uses of the contraptions.
For example, security cameras often come in handy when it comes to fighting crime. Their presence is sometimes enough to deter opportunistic thieves and when people are brazen enough to engage in illegal acts despite the devices, the footage captured can often be used as part of a criminal case against the individual or group in question.
Meanwhile, these days a considerable number of companies make use of the items to aid their industrial processes. They are particularly useful in environments that are too dangerous for people to monitor processes themselves, such as nuclear reactors.
A further use of CCTV systems is in the monitoring of traffic. Those responsible for the running of highways can use them to monitor congestion and accidents, meaning the responses to such things are as effective as possible.
In addition, they can come in handy in terms of transport safety. For example, subway train drivers can use them to ensure passengers are clear of the doors before they are closed.
This is by no means an exhaustive list of the uses of such cameras, but it gives an impression of their significance and diversity.
