On 12 May 2015, the Hungary DPA released a non-binding guidance on the access and information rights of the data subject relating to CCTV surveillance. The DPA articulated that the data subject shall be granted access to the camera records, however, due to the protection of the rights of other data subjects (third persons) appearing on the video recording, the copy of such CCTV records may not be handed over to the person requesting access.
