CCTV, short for “closed-circuit television”, is a technology that has actually been around since the early 1940s, believe it or not!
The system that was developed back in those days is somewhat archaic by today’s standards, but nevertheless CCTV technology has evolved since then and is now the best way of monitoring all manner of domestic, commercial and industrial premises.
There are many benefits to having an effective CCTV system in operation. There is the obvious benefit that it lets you monitor all sorts of indoor and outdoor locations from a remote location, so that you don’t have to be there in person.
In that respect, CCTV systems are certainly cost-effective, as you don’t have to go to the trouble or expense of hiring security personnel to monitor those areas 24/7. And whilst I am on the subject of monitoring, these days you don’t even need to have a dedicated monitoring room because CCTV cameras can typically be viewed from anywhere around the world, at any time!
Although CCTV systems are marketed as security devices, they can also be used for other purposes. For example, nations that send out rockets into space can use them to check for any equipment malfunctions, and some people even use them for wildlife purposes, such as studying the habits of wild birds and animals in their natural habitats.
