 Cisco AVC (Application Visibility and Control) on a Cisco Wireless LAN Controller (WLC) is used to prioritize traffic by marking the packets. For Cisco IP cameras that use the wireless network, the AVC rule would be configured to mark the packets with a specific QoS value, ensuring that the video traffic is treated with higher priority as it traverses the network. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
