Axis IP-Surveillance system Design Manual page 5

A megapixel network camera (i.e. one that delivers an image comprised of 1 million or more pixels)
can also offer resolutions greater than what an analog camera can offer, which means that more
detail or larger areas can be covered.

3) Easy, future-proof integration: Network video products based on open standards can be easily
integrated with computer and Ethernet-based information, audio and security systems, video
management and application software, and other digital devices. For instance, a network camera
can be linked to specialized software programs that could, for example, integrate video with a
Point of Sales system, or analyze the visual and/or audio data to detect wanted persons in a crowd
or unauthorized access to specific areas.
4) Scalable and flexible: An IP-Surveillance system can grow with your needs. You can add as many
network video products to the system as desired without significant or costly changes to the
network infrastructure. You can place and network the products from virtually any location, and the
system can be as open or as closed as you wish.
5) Cost-effective: An IP-Surveillance system has a lower total cost of ownership than a traditional
analog CCTV surveillance. Management and equipment costs are lower since back-end applica-
tions and storage run on industry standard, open systems-based servers—not on proprietary hard-
ware such as a DVR in the case of an analog CCTV system. Additional cost savings come from the
infrastructure used. IP-based video streams can be routed around the world using a variety of
interoperable infrastructure. IP-based networks such as LANs and the Internet, and various
connection methods such as wireless are much less expensive alternatives than traditional
coaxial and fiber needed for an analog CCTV system. In addition, an IP infrastructure can be
leveraged for other applications across the organization.
Furthermore, Power over Ethernet (PoE) technology, which cannot be applied in an analog video
system, can be used in a network video system to increase savings and reliability.
