Technology described herein includes a method that includes receiving, at one or more processing devices at one or more locations, one or more image frames; receiving, at the one or more processing devices, one or more signals representing outputs of one or more light sensors of a device; estimating, by the one or more processing devices based on the one or more image frames, one or more illuminance values; determining, by the one or more processing devices, that a degree of correlation between (i) a first illuminance represented by the one or more illuminance values and (ii) a second illuminance represented by the one or more signals fails to satisfy a threshold condition; and in response to determining that the degree of correlation fails to satisfy the threshold condition, determining, by the one or more processing devices, presence of an adverse condition associated with the device.
