A device, which is attachable to an aerial vehicle, for obtaining surveillance information about an area of interest, the device comprising: a camera configured to obtain image data of an object in the area of interest based on a position of the aerial vehicle; a transceiver configured to receive operator controls and to output the image data obtained by the camera; a designator unit configured to emit a light from a light source onto a surface of an object of interest to illuminate that surface when a designation command is received from an operator; an inertial measurement unit; a gimbal mechanism having a plurality of motors configured to orient the designator unit; a gimbal controller configured to control the plurality of motors of the gimbal mechanism to control orientation of the designator unit; and a central controller configured to receive flight information of the aerial vehicle based on the position of the aerial vehicle, and to control the designator unit to continuously emit the light from the light source onto the surface of the object of interest irrespective of the position of the vehicle, wherein the central controller is configured to control the gimbal controller to compensate for an orientation of the designator unit based on movement of the aerial vehicle such that the designator unit continuously illuminates the surface of the object of interest regardless of a position of the aerial vehicle, and wherein the gimbal controller is configured to: detect a change in position of the aerial vehicle based on information received from the inertial measurement unit included in said device, and from an inertial measurement unit included in the aerial vehicle, the detection occurring after the designator unit, at a first orientation, has emitted the light from the light source onto the surface of the object of interest while the aerial vehicle was in a first position, and control the gimbal mechanism to reorient the designator unit relative to the detected changed position of the aerial vehicle to cause the designator unit to emit, at a second orientation different from the first orientation, the light from the light source onto the surface of the object at the detected changed position of the aerial vehicle, such that the designator unit continuously illuminates the surface of the object of interest when the aerial vehicle is in the first position and the detected changed position. a camera configured to obtain image data of an object in the area of interest based on a position of the aerial vehicle;
