The default scanner repurposes the sensor from the automatic lighting in one of the offices and uses it for a short range, all around scan. The scanning is pretty basic but it gives a full periphery scan as well as a little bit of a warning about objects approaching. Its never going to be earth shattering but it should give you enough to get your first drone up and running and feeling its way around.
