Live camera streams can be displayed inside the HMI pages through the RTSP protocol.
This allows operators to keep an eye on the plant, machines and critical areas right next to the process data, without dedicated monitors or external viewers.
Seeing is deciding: when an alarm fires, a live image of the area tells immediately whether it is a false trigger or a real problem, before sending anyone on site. Several streams can be displayed at the same time on the same pages, critical or dangerous areas can be checked visually before restarting a machine, and through a properly configured VPN the same streams support remote assistance and unattended installations.
Cameras and ONVIF-compliant devices can also deliver their events to the HMI solution: see ONVIF integration.
