Georgia wiretapping laws, according to Georgia state law, permit the use of voice recording devices as long as one person gives consent to the recording of a conversation. Georgia makes it illegal to record phone conversations or in person conversation originating in a private place, unless one person in the conversation gives their consent to being recorded, see "Ga. Code 16-11-62(1), and 16-11-66". This in no way has to do with video cameras however which are covered by "GA. code 16-11-62 and 16-11-64.3". These code sections can be found in the Georgia Law Enforcement Handbook which includes information on the criminal law and criminal procedure.
A person can "tap" his or her own phone and record the conversation without the permission of the person to whom they are talking. That is because the person is consenting to the recording and they are actively involved in the conversation being recorded.
A person may have a small tape recorder with a microphone (like a lapel mike) attached somewhere on their person whether visible or not. It is legal to record a conversation they have without the other party's consent. This is because the recorder is consenting to the recording and Georgia state recording law is a one party consent rule.
