Tasker is an automation solution for Android smartphones. It can help you, for example, send an SMS or change ringer volume based on your location or by the schedule.
IP Webcam Pro can generate Tasker events, either with web interface or with customizable UI.
To configure Tasker for using IP Webcam events, create a new Profile using "+" button and select State ⇨ Plugin ⇨ IP Webcam as a trigger.
Events generated from web interface have the same event name as the button text. For example, the central button generates the event named "5".
