Abstract
A method for identifying an IP camera and enhancing transmission quality by packet transmission based on the ONVIF specifications is applied to a gateway device configured for data transmission to and from at least one IP camera and a network video recorder according to the ONVIF specifications. The gateway device sends a Probe packet to the IP camera after receiving therefrom a Hello packet, analyzes a ProbeMatch packet from the IP camera to identify the IP camera, relays a Resolve packet from the network video recorder to the IP camera in order to receive audiovisual data from the IP camera, and adds an exclusive group code (e.g., VLAN ID) and the highest transmission speed classification (e.g., Quality of Service) to the received audiovisual data to distinguish the audiovisual data from other network packets and give higher priority of transmission to the audiovisual data.
