You can find cctv cameras, or closed circuit television, security systems in many countries. China has millions of them alone. There are more in China than many other countries. CCTV cameras are also in other places like the UK, US, Canada, and elsewhere. The CCTV cameras capture footage that can be accessed later by authorities. They can use cameras in places to help keep an eye on things and possibly prevent crime. From bus stations and train stations, to watching over large crowds that gather at stadiums etc, there are many ways the cameras are used.

That is because of the value the cameras offer. These cameras are relatively cheap to install nowadays and bring great value as far as offering you a way to watch over a certain area. That might be your home, your car park, or some other region. It could be watching a hotel, a bus depot, or outside of a government building. The cctv cameras are in action in many places around the world today watching over many things. Because of that you can find thousands of videos online with the cctv footage that has been captured. There are literally thousands of videos online that feature that footage from cctv cameras. You can find cctv footage from China, the United States, around the United Kingdom, and other areas.
