The breakthrough of CCTV technology is that now you can use CCTV cameras with built-in audio recording function to improve safety and peace of mind, and the cost is extremely low.
Can Security Cameras Record Audio?
When it comes to camera technology, the answer is definitely yes. The sensitivity of the built-in microphone is sufficient to pick up noise in the surveillance area, and the IP camera can record audio and video.
Some CCTV cameras with audio input also allow you to add an external microphone to record audio. There is no doubt that a security camera with sound provides you with unparalleled advantages. For example, you can listen to your children, pets or visitors remotely without having to be there in person.

CCTV cameras with audio are usually reserved for families rather than businesses, so commercial cameras usually do not have a built-in microphone to save production costs. If you need a commercial CCTV system that can record audio, it will become expensive, but even if you are willing to spend the extra money, think twice. In most cases, it is illegal to record sounds in public places.

Depending on the situation, audio monitoring may be illegal. When it comes to audio monitoring, this is not a common topic. Each state has different audio surveillance laws in order to use electronic call recording.
