Closed circuit TV system, otherwise known as CCTV, is a type of video monitoring system that has been around since the 1940s. It was first used by Siemens AG to observe rocket launchings in Peenemunde, Germany. CCTV systems are based on strategically placed video cameras, which capture footage and then broadcast it to either a private (closed) network of monitors for real-time viewing, or to a video recorder (either analog or digital) for later reference.
Even though CCTV was originally implemented to improve the development of rockets, over the past six decades, it has become an increasingly important factor in security and surveillance for governments, law enforcement, schools, businesses and even homeowners. Let’s take a closer look at the many ways in which CCTV is used today.
MONITORING TRAFFIC
Ever open your mailbox to find a ticket for running a red light or speeding, even though you were never actually pulled over by police? That’s all thanks to closed circuit traffic monitoring systems. But while we all hear about the growing number of “red light cameras” popping up at busy and dangerous intersections, video surveillance isn’t just for issuing traffic tickets.
With ever-increasing traffic volumes in metro areas, interstates and local roads have become far more congested — and reckless driving and accidents happen more frequently than ever. Many cities now mount surveillance cameras above busy roadways to monitor traffic flow, watch for aggressive or reckless driving and examine the details of crashes and vehicle wrecks.
HOME SECURITY
Nowadays, it’s not unusual for homeowners to install closed circuit cameras around their homes and properties, to protect against trespassing, burglaries and vandalism. While the cameras themselves can’t do anything to physically prevent crimes from occurring in an around the home, they’ve become very effective deterrents — a well-monitored home is far less appealing to criminals than one with no security measures in place.
Another form of CCTV surveillance in the home is the “nanny cam,” a small video camera that is often disguised to look like an ordinary household object. These cameras are placed in areas of the home where nannies, babysitters and other household staff/employees are likely to spend time. Undercover security cameras bring peace of mind to parents and homeowners who want to be reassured that their children and belongings are safe and being treated appropriately.
PUBLIC TRANSPORTATION
From trains and buses to subways and taxis, public transit is becoming ever more protected by CCTV, with surveillance cameras being installed not only in vehicles, but in stations and depots as well. Video monitoring helps to deter crimes against passengers, drivers and conductors. It also provides visual evidence for prosecution if an individual is victimized — or property is destroyed.
BUSINESS SURVEILLANCE
CCTV is one of the easiest ways for business owners to monitor employees and deter crimes in their establishments. Whether the place of business is a restaurant, office, bank or retail store, cameras placed in money-handling areas, back offices, storage rooms and sales floors not only monitor employee access to these areas, but also help prevent theft, vandalism and other forms of misconduct.
Business surveillance is equally as important throughout off-hours as it is during business hours, especially since almost anything can happen overnight in an unoccupied facility. Security cameras not only provide evidence of theft, but also help owners and managers keep tabs on overnight cleaning and maintenance crews, to ensure that all required tasks are being carried out.
SCHOOL PROTECTION
Schools are experiencing an increased need for security surveillance, especially at the Junior High and High School levels. Many school systems have taken to using CCTV as a way monitor student flow in hallways, classroom conduct, and potential incidents in cafeterias, gymnasiums, auditoriums and parking lots. Security cameras have become a tool to curb offenses like graffiti, fights, vandalism and drug use on school grounds, as well as protect students by monitoring individuals entering and leaving the campus.
