Q1. What is CCTV? Explain its importance in retail store.
Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.
It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint, or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. Videotelephony is seldom called “CCTV” but the use of video in distance education, where it is an important tool, is often so called.[1][2]
In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing Digital Video Recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion-detection and email alerts). More recently, decentralized IP-based CCTV cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation.
Surveillance of the public using CCTV is particularly common in many areas around the world including the United Kingdom, where there are reportedly more cameras per person than in any other country in the world.[3] There and elsewhere, its increasing use has triggered a debate about security versus privacy.
Closed circuit television cameras are used in a variety of circumstances to provide video surveillance. School districts use CCTV to monitor the activity on school campuses. Businesses use CCTV cameras to monitor the behavior of employees. CCTV can also help retail establishments by providing protection against loss from theft. However, the use of CCTV surveillance is not without controversy. Each establishment must weigh the benefits and drawbacks to decide if CCTV is the right method of protection.
Crime Deterrent
- If CCTV cameras constantly monitor a retail business, criminals will likely seek an easier target. If employees know that they are constantly being watched, they are less likely to steal from their employer or waste time on the job. School children who know that their every move is being recorded may be less likely to carry guns to school or engage in criminal activities on campus.
Protect Employees
- Customer service employees are often required to handle angry or frustrated customers. Face-to-face interactions with an angry customer can put the employee in physical danger. CCTV cameras may save employees from harm by monitoring these volatile situations. They also serve as a deterrent from violent behavior by these customers.

Keeps a Record
- If a crime occurs in an establishment that has installed CCTV surveillance, investigation will be aided by the video. If an argument occurs between two employees, the employer can consult the videotape to determine what actually occurred.
CCTV Doesn’t Always Work
- Unfortunately, CCTV is usually not able to display every square inch of a business or facility. Even if the cameras are positioned correctly, there is no guarantee that the cameras will catch any crime or unwanted behavior done on the property. These cameras can sometimes be thwarted by covering them up or by sticking a piece of chewing gum on the lenses. Someone who is familiar with the property may still be able to get around the surveillance and avoid getting caught. If the cameras are positioned incorrectly, the high traffic areas of the facility will not be shown on camera. In this case, much of the behavior that the CCTV cameras are designed to detect will not be captured on tape.
Privacy
- CCTV surveillance sometimes causes controversy. Opponents of CCTV systems object to the invasion of privacy that occurs with constant video monitoring. Employees under constant surveillance by CCTV cameras often oppose such monitoring of their daily behavior.
