These days, lots of modern security cameras have audio. The microphone is built into the cameras, providing a discreet and minimalistic approach to better home security.

But why would you want a camera that records audio at home? Well, cameras that also record audio make it easier to identify a suspect or in the event of an altercation or argument, provides an audio recording of the incident that can be used to support your defense or claim to either the police or in court, if necessary. 

There are many types of security cameras that have audio — take ring doorbells, for example. These have a two-way audio system, allowing the homeowner to speak to guests (unwanted and wanted). But that’s just one example — there are also classic security cameras with audio options.

So, the remainder of this blog post will discuss more on security cameras and audio recordings — what you can do, what you can’t do, and more.

Do all security cameras have audio?

A lot of security cameras in recent years contain the option to record audio. However, if your camera is a little older, it may not contain a microphone. Likewise, some cameras — even in recent years — do not contain an audio recording device.

But there’s a good reason for this — in some states, it is illegal to record audio without the permission of everyone being recorded. In other states, permission is only required by one person. 

Security cameras with no audio would be better suited to states such as California, Florida, and Nevada — these do not allow audio recordings (with expressed permission from both parties), so it would likely be cheaper and a better idea to purchase security cameras with no microphone.

On the other hand, if you’re looking to upgrade your home security in a state where one-party content is legal, then an audio-supported camera is a great option for upgrading your security a notch.

How far can a security camera pick up sound?

The average security camera that records audio can pick up sounds up to fifteen feet away. 

Security cameras are not allowed in bathrooms or similar areas where privacy is expected. Similarly, audio recording devices (cameras or not) are also not allowed. This is a clear breach of privacy and is against the law.

How do you prevent your security cameras from being hacked?

Being able to record audio and video is great — it provides extra security, reassurance, and peace of mind. But what if your camera is hacked? All of a sudden, those benefits are turned against you.

To prevent your home security cameras from being hacked, there are a few things you can do:

  • Choose a strong password and change it regularly
  • Install software upgrades 
  • Set up two-factor authentication (if available)  

If you ever notice a strange noise or movement from a camera, it’s best to reset the passwords, not only for the device, but your entire network. 

Should you purchase a security camera that records audio?

If you live in a State where audio recording is allowed with one-party consent, then we’d recommend upgrading your home security system to include a few cameras with audio recording.

The added audio will also record any arguments you have on your property — perhaps with a neighbor or unwanted guest — and will also provide better video footage in the event of vandalism, intrusion, or any other kind of trespassing or theft.

But please note that audio recording is prohibited in some states. Do not assume you can record people without checking the individual state laws. 

To summarize

If you’re looking to improve your home security, upgrading your security system to include audio-supported cameras is a great option.

But you must check your State privacy and recording laws before doing so — it may not be legal, and you may end up in trouble if you do record audio without the consent of both parties (e.g. homeowner and guest or person trespassing).
