What would be ideal is if the viofo app ( and gitup app for that matter) could send broadcast intents on motion detection, or other situations. so that tasker could react accordingly, is play sound, send txt message etc.
If the viofo has an rtsp stream, like the gitup cameras, then you wouldnt need the viofo app at all, the tinycam app just receives the rtsp stream, and acts accordingly, you can upload to dropbox/tinycam cloud.google drive when there is an incident, so it wouldnt need constant monitoring.
main thing is constant power to phone/A129. If the car was parked near a house, then this can be done inside the premises.
tinycam can link in with tasker...
