Abstract: An apparatus, method, and system for detecting an object in an environment. The apparatus comprises: a processor configured to: control an active reflected wave detector to measure wave reflections from the environment to accrue measured wave reflection data; process the measured wave reflection data to detect an object in said environment; in response to detection of said object, determine whether a first predetermined condition in respect of the object is met; and if the first predetermined condition is met, control an output device to output a deterrent.

Abstract: An apparatus, method and system for detecting an object in an environment. The apparatus comprises: a processor, the processor coupled to an active reflected wave detector that is operable to measure wave reflections from the environment. The processor is configured to: process measured wave reflection data to determine whether a predetermined condition is met, the measured wave reflection data accrued by the processor in response to the active reflected wave detector being activated in response to a motion sensor detecting motion in said environment; and if the predetermined condition is met, perform at least one operation related to camera image data.
