An apparatus includes an input interface and a processor. The input interface may be configured to (i) receive a sequence of video frames of a targeted view of an environment and (ii) collect data samples from a gravity sensor (G-sensor) and a gyroscopic sensor. The processor may be configured to (i) detect axes transitions using the data samples from the gyroscopic sensor, (ii) perform, in real-time, electronic image stabilization, (iii) generate a computed horizon level based on the data samples from the G-sensor and the data samples from the gyroscopic sensor, (iv) perform, in real-time, a rotational offset compensation on stabilized captured image data of the sequence of video frames to maintain alignment of a respective horizon in each frame of the sequence of video frames with the computed horizon level, and (v) generate video analytics for the sequence of video frames using the compensated and stabilized captured image data.
