CCTV stands for Closed Circuit Television, which refers to a surveillance system using cameras that send their signals back to a specific location. These video images can be monitored live, or stored for viewing later. CCTV systems are most often used to monitor stores, banks, and public buildings, etc. However, with the technology becoming more and more affordable, and easier to use, many people are actually installing CCTV cameras in their homes and businesses for added security.

Many large stores use a combination of security personnel and a CCTV system to combat shoplifting. Smaller businesses, with smaller budgets for security, may have only one CCTV camera installed in a prominent place so that shoppers know they are being watched. A retailer can review the tapes on a VCR later, or observe any shoppers that are behaving suspiciously and note the vulnerable areas in the store. The only problem with recording and watching later is that some shoplifters will get away with stealing. On the other hand, the system still has merit because it allows for the recognition of repeat offenders.
