Television Systems--Closed Circuit
Closed circuit television systems (CCTV) are used as a security system in many businesses, industries and homes. They are surveillance systems that involve security cameras to prevent theft, robberies, break-ins and unauthorised entries. They have become an important part of security, safety and crowd control requirements.
Hidden cameras transmit a video signal to monitors observed by security personnel looking out for abnormal behaviour or violations. They are found most commonly in banks, retail stores, casinos, airports and military or government agencies and offices as detection systems. CCTV is also used in industrial plants where processes in an unsafe environment need to be observed, and can be used in large venues, such as sports stadiums or train stations to monitor crowd control.
CCTV systems can be customised to suit the monitored location and the requirements of the users. CCTV suppliers offer quotes, delivery, installation and maintenance, are available seven days a week and have 24-hour emergency services for residential, commercial or industrial customers. They can make on-site appointments to assess and advise on suitable systems, and suggest what equipment may required, such as camera types, data cabling and monitors. Temporary CCTV systems can also be installed for special events and corporate functions.
