Want to know more about CCTV & Surveillance?
CCTV is an abbreviation for closed-circuit television and it is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. For companies, CCTV equipment may be used to observe parts of a process from a central control room. These systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders (DVR's), provides recording for a period of time with a variety of quality and performance options and extra features. CCTV can be utilized for a wide variety of uses such as crime prevention, monitoring industrial processes, traffic monitoring, transport safety, control of retail and it can be used in schools and other public places.
CCTV technology offers a wide variety of capabilities such as Video Content Analysis (VCA) which is the capability of automatically analyzing video to detect and determine temporal events not based on a single image. A system using VCA can recognize changes in the environment and even identify and compare objects in the database using size, speed, and sometimes colour. A facial recognition system is a computer application for automatically identifying or verifying a person from a digital image or a video frame from a video source. One of the ways to do this is by comparing selected facial features from the image and a facial database. The technology can be either analogue or IP based. IP cameras use the Internet Protocol (IP) used by most Local Area Networks (LANs) to transmit video across data networks in digital form. IP can optionally be transmitted across the public internet, allowing users to view their cameras through any internet connection available through a computer or a 3G phone. For professional or public infrastructure security applications, IP video is restricted to within a private network or VPN or can be recorded onto a remote server.
Many consumers are turning to wireless security cameras for home surveillance. Wireless cameras do not require a video cable for video/audio transmission, simply a cable for power. Wireless cameras are also easy and inexpensive to install. Previous generations of wireless security cameras relied on analog technology; modern wireless cameras use digital technology which delivers crisper audio, sharper video, and a secure and interference-free signal.
The size of the global CCTV market is estimated at $23.3 billion in 2014 and estimates by BIS research indicates that the market will grow to exceed $55 billion by 2020, a CAGR of some 20%.The lions share is attributed to cameras which is expected to reach nearly $28 billion by 2020. Although the market is still dominated by analog based video surveillance systems globally, the use of IP cameras is expected to witness an explosive growth from 2016 onward.
In fact, studies suggest that IP cameras have already surpassed analogue CCTV as the solution of choice for applications in the Middle East. Other reports predicts that network video surveillance equipment will represent 79 per cent of the total Middle Eastern market by 2016. This dramatic jump will be fueled, in part, by large infrastructure projects. As per a report prepared by HIS, the Middle East market for CCTV was estimated at $390 million in 2013, a number which is likely to grow significantly over the coming years driven by a combination of legislation, construction and major events such as Dubai 2020 Expo and FIFA World Cup in Qatar.
