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.
