Register movement from UVC Cameras

The official UVC app can receive push notifications from the NVR when motion is detected. It would be great if HASS could fetch these as well.
If it´s not possible to get it using the API maybe something can be done with the motion.log file?
This file register start/stop of every motion:

type:start event:6979 clock:1508717358 (CAMERANAME) in app-event-bus-6
1496860573.273 2017-06-07 20:36:13.273/CEST: INFO Camera[0418D623836D]
type:stop event:6979 clock:1508724121 (CAMERANAME) in app-event-bus-3

This is exactly what I need! I can use this feature to turn on lights based on movement and in specific zones too
