Can CCTV Cameras Record Sound – Yes, in Terms of Technology

If you ask: can security cameras record audio?

The answer is definitely YES in terms of the camera technology.

In virtue of the built-in microphones that are sensitive enough to pick up the sound within the monitoring zones, the IP cameras are capable to record both audio and videos.

For some of the security cameras with audio input, they can also allow you to add an external microphone for sound recording, like the outdoor security camera Reolink RLC-423.

There is no doubt that security cameras with audio offer you unparalleled benefits. For example, you can listen to your baby, pets or visitors from afar without physically being there.

Can Security Cameras Record Audio Legally – That Depends

The audio surveillance laws by state vary from place to place and are generally stricter than video monitoring regulations.

And that's also explains why not all security cameras have audio.

To help you learn whether it is illegal to have security cameras with sound in your location, here are a few factors you need to check out.

#1. Where are the CCTV cameras with voice recording installed? If the security cameras with audio are placed in your home for security purpose, then without any doubt, your CCTV cameras can record audio legally.

When it comes to the places where people have the expectation of privacy, such as the bedrooms, dressing rooms, toilets, etc., both audio and video recording are not allowed.

The legality of audio recording in public places can be more complicated and you'll have to consider other factors (listed below) as well.

#2. Does the subject consent to audio recording? According to the privacy laws in most states, CCTV cameras cannot record sound unless you obtain the consent of at least one party involved in the conversation.

In such places as California, Connecticut, Delaware, Florida, Hawaii, Illinois, Kansas, Maryland, Massachusetts, Michigan, Montana, Nevada, New Hampshire, Pennsylvania, Utah, and Washington, all-party consent is required before your security cameras can record sound legally.

Also, putting up signs which specify that audio recording is taking place can also be regarded as consent in most states. For example, the small business owners usually would place a sign indicating the use of retail store security cameras.

The most reliable way to learn if security cameras can have audio, is to search related local, state, and federal laws or to consult your attorney directly before you have one camera installed.

How to Tell If Security Cameras Have Audio

If you notice an IP camera in public places and want to check if this CCTV camera is recording audio, maybe you can only ask the camera owner as the microphones are normally unnoticeable from a distance.

However, there are multiple ways available for you to tell if your newly bought CCTV camera has audio.

  • Look through the product page as well as the tech specifications to see if audio recording is listed as a highlight of your security cameras.
  • For the security cameras that have audio or sound recording, generally there is a small hole (microphone) in the camera housing for sound pickup, just like the one in Reolink RLC-410 as showed below.
