Airport Upgrade RFP Reviewed

Author: John Honovich, Published on Nov 25, 2010

A US airport has released an RFP looking to upgrade their surveillance system to migrate to an IP video solution. To do so, they want to convert their exist cameras to run on their LAN and deploy a storage area network. In this note, we look at some important design tradeoffs in this approach. The specification itself is rather short. Members should review the Airport's specification.

  • Re-using *** ********* ***: We are a somewhat surprised about the Airport re-using their corporate LAN for video surveillance. While the Airport requires a dedicated VLAN for surveillance, VLANs do not prevent overloading a network's bandwidth. Whether this is a real risk, depends on the size and load of the network plus the bandwidth requirements of the cameras. Many organizations choose to build a separate LAN infrastructure for surveillance to avoid this.

  • Deploying * ******* **** ******* (***): For larger deployments, storage area networks offer cost and management savings.

  • Access ******* ***********: Requiring new surveillance recorders to integrate with existing access control systems is extremely common for large scale organizations. In the US, one of the most common is Software House's CCURE. Integrating these systems is important in quickly visually verifying and monitoring movement throughout a facility. The downside of such requirements is that it significantly reduces the VMS systems that the organization can consider.
