United States Law

Questions regarding audio monitoring 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, and state laws are quite similar.

As such, we work closely with our customers to ensure that our audio security products are used overtly and in compliance with all laws. If you have legal concerns regarding audio, we recommend verifying this information with an attorney.

For consumers today, audio is an integral part of their everyday lives, from voice command virtual assistants like Alexa, Siri, and Google Home units, to smart phone applications. In security, audio is being increasingly adopted to verify alarms, enhance communications, and provide an added layer of protection. As societal expectations and overall comfort with audio have evolved, the security industry has also progressed to confirm the importance of audio in the total security solution.
