Keep in mind that video and audio monitoring laws vary from state. Before using these devices, enterprises must comply with the laws of the state.
Many employers use video records of employees to ensure safety and prevent theft. This seems acceptable under most state laws, as long as employees know they are being recorded. But each state formulates its own rules, which increases the complexity of the problem.
For example, the laws of Tellawa and Connecticut stipulate that if there is video surveillance that “may destroy any privacy expectations (such as in a bathroom or locker room)”, companies must notify customers and their employees. The surveillance video part, but how about the audio? This is also different from the state.

How To Tell if a Security Camera Has Audio?
There are several ways to determine whether the security camera is recorded.
One method is to check the specifications of the camera. Most secure cameras with audio functions are listed in their specifications.
Another method is to see the camera itself. If there is a small pinhole near the camera lens, it is likely to have a microphone and record audio.
Finally, you can inquire about the audio function of the camera to the seller or manufacturer. They should be able to tell you whether the camera records the audio and the audio type (one-way or two-way) it recorded.
How Far Can Security Cameras Hear Audio?
On average, security cameras can capture audio from 100 to 150 feet away.
Security cameras record audio in much the same way humans do: They can only hear and record sounds close enough for the microphones to pick up.
Any object beyond its listed distance from the camera should generally not be recorded. In this regard, security cameras are no different from human listeners.
However, not expected to be recorded does not mean that it cannot be recorded. If the sound source is loud enough, the microphone can still pick it up and capture it as part of the recording.
Another factor that determines how far a security camera can record audio is the direction of the sound source.
Depending on its location, a security camera might record sound from all directions, or just forward and forward.
In most cases, security cameras are most effective when they are facing forward, as most sound sources are unlikely to be directed toward the camera.

This is done to ensure that no one can hear what is being recorded.
Conclusion
The use of audio components to enhance the video capture function is both good and risky. Audio monitoring cameras can be added to the information you captured to better make decisions. But this also brings some legal risks.
