Surveillance systems use video cameras designed to different specifications and packaged in various enclosures depending on a number of variables. Cameras are also categorized by the data type and format communicated to the rest of the system. Analog cameras use linear signals, while network cameras provide streams of digital data. Analog cameras continue to lead the surveillance camera market mainly due to the cost associated with new installations or upgrades to network cameras. Recent In-Stat research forecasts that worldwide unit shipments of security analog cameras will reach nearly 44 million by 2014, but the rate of growth in network cameras will eventually surpass analog cameras.

“The most important advantage the network camera has over the analog camera is the Internet Protocol it employs in its communication with the rest of the system,” says Max Baron, Contributing Analyst, In-Stat. “And although the network camera's capability to interface to recorders, switches, computers, servers and the Internet can make the surveillance system itself easy to upgrade and expand, the price of the camera and the cost of upgraded infrastructure, frequently outweighs that advantage.”
Research by In-Stat found the following:
? Video surveillance equipment revenue will approach US$15 billion in 2014.
? Growth in network cameras surpasses analog cameras and drives higher growth rates in hybrid DVRs and NVRs.
? Revenue for processors in network cameras, including video encode/image processors and analytics processors, will be 67 percent higher in 2014 compared to 2010.
? Asia Pacific leads in worldwide security camera shipments.
? Video surveillance equipment can be found in vertical applications for toll booths, education campuses, public transportation, vehicular traffic monitoring and law enforcement; as well as in applications such as monitoring health conditions of patients in hospitals and at home, and queue length management in retail.
