IP-based video surveillance is easy to extend as and when the need arises. Cabling requirements are far less complex than for an analog system, and with a foundation of open standards you are not tied to proprietary technology.
Adding more cameras or functions to an analog system means a lot of new cabling, and matching the new equipment to your proprietary system could mean a limited selection from only one vendor.
Axis is a founding member of ONVIF, an open industry forum for the development of a global standard for the interface of IP-based physical security products. ONVIF ensures that IP-based equipment from different manufacturers can co-exist and interoperate on the same network.
By using standard IP components, you ensure easy integration with other systems. You can easily route your video to wherever you need it, from day to day, and cameras can be upgraded with intelligent plugins to extend functionality.
