Abstract
An apparatus comprising a plurality of detection devices, a processor and a controller. The plurality of detection devices may each be configured to (i) detect objects in a respective zone and (ii) generate a wakeup signal in response to detecting the objects. The processor may be configured to (i) perform analysis of one or more frames of a video captured by an image sensor and (ii) evaluate a detection of the objects by the detection devices based on the analysis. The controller may be configured to (i) activate the processor in response to the wakeup signal and (ii) provide feedback to the detection devices based on the evaluation by the processor.
