Although you will find a number of covert video cameras and microchip cameras with built-in sound, they are actually illegal. In fact, U.S. Customs have raided some places selling them in recent years. The surveillance professional needs to understand that the laws dealing with covert audio recording are much different than those dealing with cover video recording.
In states that permit one party consent, one party must consent to the audio recording. In those states that operate under two party consent, all parties must provide consent to the audio recording. In no state is there any such thing as no party consent. Thus, any covert video camera with audio would be considered an illegal eavesdropping device.Louisiana is a one party consent state. This means you can record your conversation with another person because you are the consenting party!
