Hybrid solutions. Most hospitals have an existing video surveillance system in place, and if it is at least several years old, it is very likely an analog system. These institutions face the challenge of upgrading their analog systems while keeping costs down and preserving previous investments in technology. Fortunately, it is now possible to expand an analog system using a hybrid strategy to enhance coverage and to have most, if not all of the functionality of an all-IP system. For example, Scottsdale Healthcare in Arizona has installed 125 Panasonic cameras and is looking to double that number over the next year using a combination of best-in-breed network and analog video solutions.
