A blanking device generates a blanking signal to obscure signals on a license plate in response to a monitoring flash directed at the license plate. The device includes at least two sensors spaced apart to enable the device to differentiate between a monitoring flash from a device attempting to take an image of the license plate and other spurious signals.
