CCTV has become ubiquitous in large cities, along major highways, and areas that host large events. On streets and roads, CCTV is often used in traffic law enforcement, but it’s used to monitor traffic patterns, allowing emergency services to react quickly to accidents and for maintenance departments to better plan necessary construction projects. In hotels, stadiums, and convention centers, CCTV is often used in private television networks, broadcasting sporting events or special events throughout their facilities.

Most airports and train stations throughout the world have installed security cameras connected to CCTV systems with the goal of combating terrorism. These video feeds are constantly monitored by local and international law enforcement agencies in an effort to keep travellers safe.
