User defined variables in (). Description of function: View of surveillance cameras running i Google Chrome. At trigger from line detector provided to computer via keystroke, send screenshot to Telegram App. Result: Fast alarm with snapshot and preview to phone. Alarm history in Telegram app in phone. Notes: I have run this above function for test with a macro in Macro Express. The result is fantastic but I need a more stable and elegant solution. As far as I know It should possible to send to Telegram via some sort of script without typing in actual desktop app. (delay) in function is to compensate for lag in ip-camera stream. Using view from Google Chorme instead of camera stream makes it possible to send alarm picture containing information from several cameras. And no, this function or similar is for some reason not provided from any surveillance camera vendor.
