Analog CCTV vs IP Surveillance
Closed Circuit Television (CCTV) uses analog broadcast formats to send camera signals over a private network for viewing on a limited set of monitors. It was initially developed in the 1940s as a way for scientists to monitor rocket launches. By the 1980s, CCTV was increasingly installed in public spaces as a crime deterrent, and in buildings to monitor the movement of people.
Time lapse videography, motion-only recording and digital multiplexing technology emerged in the 1990s. In 1996, Axis Communications released the first Internet Protocol (IP) camera. The Digital Video Recorder (DVR) was introduced at the end of the decade. These advancements made CCTV systems more efficient and less costly. Installations in both public and private spaces became more common.
As digital video technology advanced, cameras became more powerful. High Definition (HD or HiDef) imagery, improved optics, smaller size, Power over Ethernet (PoE), and wireless cameras make it possible to install systems anywhere. Analog to digital converters can extend the useful life of conventional video cameras.
Cameras can be connected to a Local Area Network (LAN). Software enables them to be viewed over the internet using a standard browser, and through smart phones. DVRs are being displaced by NVRs (Network Video Recorders). Video data can be stored on or off site, and saved to removable media such as DVDs, memory sticks and external hard drives. Legacy CCTV systems have been rendered obsolete.
IP Surveillance systems are now affordable for home and small office use too. And they’re not just for securlity anymore. For example, they are used in manufacturing to increase safety, productivity and efficiency; in retail to monitor inventory and analyze customer traffic; in logisitcs to watch vehicles, cargo and property; in schools to prevent violence, theft and vandalism; and to observe multiple branches from a single location.
IP Surveillance systems also make use of Video Analytics. Motion sensors can detect movement in unauthorized directions or as it crosses a certain point in a camera’s view. Video Analytics are used for license plate detection, congestion awareness, entry of unauthorized vehicles and people into restricted areas, and detection of unattended objects. This technology is an evolving facet of IP Surveillance.
No two homes are the same, and no two businesses are the same. Yet many IP Surveillance systems take a one-size-fits-all approach. Technocom has developed the UGuardU system to provide a low cost, flexible IP Surveillance solution that can be uniquely sized and customized to meet specific applications.
