Security cameras are a typical everyday security feature. That’s because video monitoring is the easiest way to keep tabs on what’s happening around your property. However, there’s only so much information you can glean from a video recording. This begs the question, do security cameras have audio?

With technological advancement, security cameras can be your eyes on the ground. You can track activities in your home even when you’re not around. If cameras have audio, that would mean you have an extra layer of security. When you have cameras that record sound, you can keep your finger on the pulse of what’s happening on the premises.

In this article, we answer the question, “Do security cameras have audio?” We also look at your options and the potential benefits of adding audio to your security system.

Do Security Cameras Have Audio?

Security cameras with both video and audio recording capabilities do exist. There are several types of these cameras available on the market:

  • Security cameras with add-on microphones. In the past, many security cameras with audio recording didn’t have this as an in-built feature. Instead, you have to add a mic to the camera via an external microphone input jack.
  • Security cameras with in-built audio features. Modern cameras come with an in-built audio feature.
  • IP audio surveillance cameras. This type of camera captures audio signals and stores them in the cloud. Basically, it’s a digital camera. It can send signals over cable or Wireless IP camera network connections. The audio recordings are stored in the network. This makes the data accessible through different digital devices.
  • Analog audio surveillance cameras. Analog cameras with audio are traditional. They send the captured audio signals over cable to onsite DVRs. So you can only access the audio recordings through the DVR.
  • Security camera with two-way audio. Two-way audio systems come with a built-in microphone and speaker. This enables you to communicate with people on the other end even if you’re not physically present.

Camera technology is continually improving. You may be wondering, “Why don’t all security cameras have audio?” It’s because there are some legal issues involved. Generally, there should be no problem if your security camera records audio in your home. It’s all part of your security measures. But, be sure to avoid installing security cameras with audio in places that come with the expectation of privacy, such as bathrooms.

Benefits of Audio Surveillance Cameras

Here are the top benefits associated with installing a security camera with audio recording.

Deters Criminals

Today there are many innovations in security camera technology. This ensures that the fight against crime is more effective. As of 2022, most security cameras with audio allow for two-way communication. Once you’re alerted to a specific suspicious sound, such as the sound of a window breaking, you can issue a warning.

This should be enough to stop the intruder in their tracks. Criminals count on stealth. So, once they know they have been seen, they rarely ever proceed with their nefarious actions. This is especially so if you use the audio feature to announce that the police are on their way. Some cameras even come with in-built sirens to scare off intruders and alert people nearby.

Improves Security

CCTV cameras with enabled voice recording help to boost security. That’s because you now have both eyes and ears on the ground. You can even receive alerts wherever you’re, so your home is always protected.

Also, suppose you capture audio that alerts you to the possibility of criminal activity. Then, you can quickly take steps to prevent said activity from happening. As long as you stick to quality camera solutions, you can detect sound across various decibels. Also, you’ll be able to capture sound from several feet away, which helps expand the reach of your security measures.

The addition of the right security features can even do wonders for your home insurance costs. Generally, insurance companies charge lower premiums if they believe the risk is low. This potentially makes audio surveillance cameras a cost-effective solution with a great ROI.

Gives You The Bigger Picture

When your security monitoring system doesn’t include video, you don’t have all the facts on hand. For instance, you may notice some individuals talking to each other and acting suspiciously outside your door. But, without sound, it isn’t easy to gauge what they are up to.

Once you add sound, the picture becomes complete. No matter how stealthy intruders are, it’s very difficult to mask sounds. It’s not only about intruders. Some situations may involve visitors and residents of your home. During these situations, listening to audio recordings gives you the full details of the story. That way, you can make wiser decisions.

Enhances Surveillance Capabilities

Video surveillance is indeed the mainstay of any security monitoring system. However, adding audio adds a valuable layer of security. When it comes to your home’s protection, there’s no such thing as too much security.

Overall, security cameras with audio offer enhanced surveillance capabilities. They help prevent residential burglary by warning off intruders. Modern homes need modern security features. This is necessary because burglars and criminals work hard to beat outdated security cameras. A security camera with audio enables you to stay one step ahead. This is better than reacting only after you’ve been robbed.
