Most security cameras do not record sound. This is because most jurisdictions have laws that require two-party consent for recording conversations. Security cameras are generally only equipped with microphones if they are being used for a specific purpose, like monitoring a baby’s room or detecting breaking glass.
If you’re wondering whether your security camera records sound, the answer is probably no. But there are a few exceptions to this rule.
