Designing Intelligence Into Door-entry And Security Systems

摘要

Personal security at home, on the street, or in a military setting is a permanent and growing concern; as a result, the products and technologies that address this security continue to see rapid market growth. A significant part of this market uses IP (Internet Protocol) video-surveillance systems-from extensive camera installations in metropolitan areas to small businesses and residences. Although this article refers to "door-entry systems," keep in mind that you can apply this technology to many markets-video doorbells, video baby monitors, and even military applications. Door-entry and video-surveillance systems have become more realistic propositions at the low end of the market in both deployment and overall cost, mainly because of technological advances that support lower prices.
