Tip! The second wave of increased video surveillance corresponded with the emergence of digital in the United States. From 1997 on, police departments across the country installed more and more video surveillance cameras in public buildings, housing projects and areas like New York’s Washington Square Park.
A surveillance camera is nothing new when a customer walks into a retail store, convenience store, even a college or school. But surveillance cameras come in a variety of styles and have many functions to accommodate the consumer’s needs and preferences. Surveillance in general is watching and observing selected areas for any interference, such as theft, burglary or vandalism. You can have something as small as a peephole surveillance camera to observe who comes to your door without them knowing, or upgrade with audio surveillance equipment where you can speak or listen to the outside as well. Surveillance equipment can come as small or as large as needed, can zoom in or out, there are even spy cameras and wireless cameras out there where large companies can hide cameras to observe their employees activities.
