Analog Solutions
Even though IP surveillance is the next generation, analog solutions are available and viable. Products from vendors such as Honeywell, Everfocus, Pelco, Bosch and Aver are highly recommended.
Evolution of video surveillance systems
Video surveillance systems have existed for some 25 years, starting out as 100% analog systems and gradually becoming digitized. Today's systems have come a long way from the early analog tube cameras connected to a VCR. They now use network cameras and PC servers for video recording in a fully digitized system.
However, in between the fully analog and the fully digital systems, there are several solutions which are partly digital; these solutions include a number of digital components but do not represent fully digital systems. In true network video systems, the video is continuously being transported over an IP network, and which are fully scalable and flexible.
