Surveillance is a practice that is not simply limited to cameras. Any instrument or device that watches or monitors someone or something, whether it be a human, a camera, a microphone, a motion detector, or a trip wire, is a form of surveillance equipment. Since the variety and types of surveillance are nearly endless, surveillance equipment is also an extremely open concept. Surveillance equipment can be tailored to fit specific industries or groups depending on their surveillance needs. A large retail store might need a comprehensive, linked security camera system that works in conjunction with a loss control staff - including uniformed security guards and plainclothes staff members. A company with heavy industrial needs might require a heavy-duty camera and a staff of scientists/observers to monitor factory out put or industrial processes. While security systems and surveillance equipment can be an effective addition to a company, and may save you time and money in the unlikely event of a robbery, knowing which surveillance equipment is right for your business is the most important element of having a smart security system.
