Room surveillance, or preparation or video, audio and audiovisual recordings, is possible pursuant to Section 114 of the Criminal Procedure Code. Slovak legislation allows for the production of video, audio or video-audio records associated with direct entry into the dwelling. This investigative measure is admissible only in criminal proceedings on crime, corruption, the crime of abuse of power by a public official, the crime of money laundering or another intentional criminal offense, which is bound by an international agreement, and only with the prior consent of the judge, before the commencement of criminal proceedings or in the preparatory proceedings of the judge for the preliminary proceedings. The warrant for the surveillance is issued in writing by the presiding judge, before the onset of the criminal prosecution or in the preliminary hearing, upon the petition of the public prosecutor, by the judge for the preliminary hearing. The petition must be justified by the suspicion of the commission of a specific criminal activity and also information on persons and items that the preparation of the video, audio or audiovisual recordings concerns, if they are known. The period of surveillance may be up to six months and may be extended for no more than two months, even repeatedly.
