How to Tell if Security Cameras Have Audio?

After all, with so many audio surveillance cameras around us, you need to be careful with your words and actions lest you inadvertently reveal personal information. But how can we tell if there is a microphone in the security camera? We've collected 6 alternative ways to get around security cameras to protect your privacy.

Search Online for The Camera

Searching for the camera model online can help us quickly find out if a security camera is capturing audio. You can search in:

  • Google Search: This is the most basic way to search for camera models. Just simply type in the brand of the camera, or take a picture and search for it.
  • Official website: Most security camera manufacturers will list the features of their cameras on their website, including whether or not they have audio.
  • Third-party websites: You can also find this information on third-party websites that review security cameras.

Look for Overt Speaker

There are some security cameras with speakers that are visible on the outside of the camera. They are usually small and round, and they may be located on the front, back, or side of the camera. If you see an overt speaker on a security camera, it is likely that the camera is capable of recording audio.


Play Recorded Videos

Most camera manufacturers provide apps that may be installed on your mobile device. If you're not sure whether it supports audio, you can open the app, and check the app interface to see if there are audio recording buttons. However, this method doesn't work for cameras in public.


Check the Camera Serial Number

Serial number is a unique identifier that contains product information indicating whether your security camera has audio. To specifically check the serial number, it is usually located on a sticker on the bottom or side of the camera. It usually looks like a combination of letters and numbers, and is typically 12-16 characters long, including a dash or underscore between the characters.



Search for External Connection

If you have some cables connected to your camera externally, then you can check these connected cables, because some of them are just used to transfer audio. For example, some cameras will need to be connected to an external DVR in order to record audio. The external DVR will have an audio input port that the camera can be connected to. If you can't find an external DVR or connection block, then the security camera probably doesn't have audio capabilities.


Ask the Camera Manufacturer

If you've tried all of the above and still don't get the answer, the most direct way is to ask the camera manufacturer. The manufacturer will be able to tell you if the security camera has audio and if it is enabled by default. They will also be able to tell you if there are any legal restrictions on audio recording in your area. But only if you buy the security camera from an official website that provides after-sales service.
