What You Will Learn
Today's organizations need flexible, intelligent systems to help protect people and assets as well as streamline business operations. The Cisco
® Wireless Video Surveillance solution allows organizations to utilize their mobility infrastructure to install surveillance tools, such as wireless video surveillance cameras, on demand wherever there is wireless coverage.
The flexibility provided by the Cisco
® Wireless Video Surveillance Solution provides organizations with:
• Improved video surveillance coverage where cable placement is difficult
• Support for ad-hoc or temporary monitoring of locations
• Support for integration with specialized video surveillance and mobility services applications for improved operations and intelligence.
Organizations face a variety of physical security challenges. They must address liability obligations for the people within their organization, including employees, contractors, customers, and guests. They must work to prevent loss of property and limit the cost of asset loss to the organization. They must also be able to respond to threats and emergencies, whether these events manifest as campus crime or a medical crisis.
Traditionally, organizations have employed video surveillance as a tool to help address their security challenges. Analog surveillance systems provided a base level of functionality to monitor large areas from a central location without the need to maintain a personal presence. These systems could also use recorded video as an historical account of events that occurred.
While analog systems delivered surveillance coverage, they came with the additional capital and operational expense of maintaining a separate physical cabling plant (generally coaxial cable) and recording system. Costs also increased because this infrastructure was often available only through single-vendor solutions. Also, these systems didn't support using video analytics to add intelligence to the surveillance.
Today, organizations are moving to IP-based video systems to deliver video surveillance over a common infrastructure (IP networks) in a low-cost, interoperable manner. These IP-based solutions support using analytics software to add intelligence to the video surveillance system. They also deliver lower capital and operational expenses by consolidating in a unified cabling plant. IP-based solutions also allow video to be more flexibly delivered, not only to surveillance applications but any application that is based on an IP platform.
The challenges associated with both analog and IP-based video surveillance solutions include the following:
• Lack of pervasive coverage: Analog and IP video surveillance systems rely solely on wired cameras, which requires either CCTV or Ethernet cabling to be run to each camera. This can prove difficult in some locations, particularly outdoors, and can result in inadequate coverage.
• Inflexible deployment options: Because analog and IP video surveillance systems rely solely on wired cameras, organizations cannot easily place cameras on an ad hoc basis for temporary monitoring or to power applications such as video analytics software.
• Limited situational awareness: Video surveillance systems traditionally deliver video to a central monitoring location, limiting the ability for individuals in the field to gain mobile situational awareness from the surveillance system.
These challenges underscore the need for a flexible video surveillance solution, which builds on the foundation of IP-based video surveillance while also providing the flexibility of a wireless network.
The Cisco Wireless Video Surveillance solution provides a cost-effective method for delivering flexible mobile video surveillance coverage wherever there is wireless coverage. This robust surveillance solution supports a flexible, mobile architecture with powerful integration tools for IP video surveillance.
