Surveillance, Audio and the Law

Questions regarding audio monitoring and recording and the law are one of the most frequent inquiries we receive from our customers. Under U.S. law, audio monitoring is legal as long as there is no expectation of privacy amongst those being monitored. State laws are very similar. International laws vary greatly in terms of permitted applications of audio. We work closely with our customers to ensure that our products are used overtly and in compliance with all laws.
