Although the majority of surveillance camera installations are now analog, huge growth in the wireless IP video market is expected as wireless shipments supersede analog cameras and as a large majority of the 8-10 year analog camera replacement cycle comes due replacing wireless IP equipment. (ABIresearch July 19, 2010)

Thanks to a steady stream of wireless technology innova- tion, increasing popularity and ease of use, the IP camera market has migrated from high-end specialized industries such as banks and casinos, all the way down the business size chain to homeowners and small businesses.

Why are businesses and individuals so interested in wireless IP video surveillance technology?

Unlike its analog cousin, IP video cameras can record and store streaming video files, with confidence, for virtually unlimited periods of time. Furthermore, placing and aiming wireless IP surveillance cameras in blind spots and difficult access areas delivers a peace of mind that is otherwise not available via wired alternatives. Video in lieu of physical security guards can save significant costs in the long run and decrease insurance premiums and liabilities. However, wireless IP cameras are only part of the equation; stream- ing IP video is only a reliable option with a stable and fast wireless network (WLAN) where video stream quality is consistent and pervasive. When it comes to mission-critical surveillance, half measures are unacceptable.

Implementation Approach

Whether you are considering replacing an existing wired video network, extending an existing wired network into hard to wire areas, or deploying a new wireless video sur- veillance network, the implementation approach is similar.

Wireless cameras face the same bandwidth and distance challenges as laptops, iPads, and smartphones. Addressing these issues is key to success.

Environmental Considerations

RF signals are impacted by the density and type of ob- stacles between wireless radios. Line of sight and other obstacles are issues that need to be addressed, as well
as interference. This is another instance in which the site survey becomes the map to hidden treasure, in this case, the treasure is the ideal locations in which to mount the APs and client cameras.

The primary objective of a WLAN is to maximize range, reliability, and capacity when deploying Wi-Fi enabled security systems. Ruckus’ adaptive antenna technology with twice the capacity and twice the range of other vendors, results in a reliable, higher performing wireless connection regardless of environmental interference.
