Install me a System of 2 cameras that have only one trigger (wire) but make pictures simultaneously ; pictures made should be automatically uploaded in a webbased cloud (wireless)

Hi I want for my company a system where I install 2 Cameras (distance of the cams maybe 3-5 meters); there is only one trigger for both cams, and if the trigger is triggered, both cams should instantly make a picture. The cams will be imobile, so they rest where they were installed. Everytime the trigger gets activated both cams should make a picture automatically and load it up in a webbased cloud chronologically - wireless of course. The cams should run 24/7. The pictures should be listed in the cloud sorted after time of recording. Cams: I will buy whats necessary. But the cams should be connected to the internet wireless. Regards
