Information security and privacy protection aspects of CCTV Cameras

Closed-circuit television (CCTV) is a TV system in which signals are not publicly distributed, but are monitored, primarily for surveillance and security purposes. CCTV systems rely on strategic placement of cameras and observation of the camera’s input on monitors. As the cameras communicate with monitors and/or video recorders across private coaxial cable runs, or wireless communication links, they gain the designation “closed-circuit” to indicate that access to their content is limited to only those with authorisation to see it.1

The effectiveness of video surveillance technology is continuously improving, and it has already established itself as a vital security tool for the police, private companies and many public sector organisations.. An effective CCTV system contributes to the detection and prevention of crime, as well as protecting towns, cities and transport networks from the threat of terrorism.2

Advances in CCTV technologies – especially from analog CCTV cameras to internet protocol (IP) ones – certainly improves the safety and security that CCTV systems provide, but also increases information security and privacy concerns. Having in mind that the new EU privacy protection regulation, General Data Protection Regulation (GDPR), will be applied from 25th May 2018, information security and privacy protection concerns of CCTV systems are being recognised.
