Can Security Cameras Record Audio?

January 30, 2023 8:18 am

Cameras have become more and more present in society, especially for security purposes. Home and commercial security experts will tell you that video surveillance is vital to protecting your property. Even so, there’s a fine line between security and individuals’ right to privacy. What laws and aspects must you consider when installing cameras on your property? Explore what you need to know to ensure your security camera surveillance gives you the safety you need while complying with the law.

Do Security Cameras Have Audio?

Not all traditional security cameras have audio functionality. In fact, many standard surveillance cameras don’t — in part because audio recording is illegal in some states without consent from the involved parties. Additionally, conventional CCTV cameras require additional audio cables, and records of both audio and video call for a higher storage capacity.

Some of the latest technology, like Wi-Fi cameras, does feature built-in audio devices. Two-way audio is a common feature of modern security systems that use phones, and interactions can easily be recorded if the feature is not disabled.

Types of Security Camera Audio Capabilities

Most modernized camera equipment, like Wi-Fi or IP cameras, comes with installed microphones. These security cameras can use audio and may do so through the following capabilities:

• Capturing audio with video footage: These cameras aim to record auditory information that may not be in the camera frame. Suppose a person or object is not in the frame. In that case, the audio may have helpful information — perhaps you can hear an argument or a car driving off that gives context and information that aren’t necessarily captured on camera.
• Audio-triggering video recordings: Some devices use audio to trigger video recordings instead of using motion detection to initiate recording, ensuring that all the important details are captured.
• Two-way audio communication: Two-way audio works when the built-in portion of the system includes a speaker, allowing the user to speak to someone close to the security camera. This intercom-style system can be helpful for warning off intruders or communicating with family members without phones.

Traditional surveillance systems with cables and digital video recorders do not have built-in microphones. You will need to purchase surveillance equipment with these functionalities specifically if you want them and they are legal in your area.

How to Tell if Security Cameras Are Recording

Most conventional security cameras record if they are on or turning. Traditionally, cameras have many LEDs around the lens, which may be different colors and have indicators that show whether the cameras are recording. It all depends on the security camera system you have installed.

The best way to tell if your security cameras are recording and working as they should be is by checking with experts. You can always contact Wayne Alarm Systems with questions regarding your security surveillance equipment.

How to Tell if Security Cameras Are Recording Audio

Many modern camera systems have audio features that you can disable. A reputable security equipment provider can inform you of any audio recording capabilities and how to disable them if you need to do so by law. On your own, you can check whether a security camera has audio recording functionality by looking for the following features:

• Visible speaker: Many modern camera devices have a speaker. A quick visual check behind or below the security camera should reveal whether it has sound capability. Speakers indicate that there may be audio capabilities, not necessarily that there’s a microphone.
• Pinhole microphone: Look near the lens to tell whether a camera has audio. Cameras with microphones usually have a pinhole, much like smartphones and headphones do. It’s easier for a camera to pick up audio when the microphone faces the same way as the lens.
• Serial number: You can check whether a camera has audio functionality by quickly searching the model and serial number, which you can usually find underneath the camera.
• External microphones: Audio capabilities require extra external microphones. You can spot these because they are often taped to the camera and may resemble a miniature smoke alarm with cables attached.
• Audio cables: Most security cameras use coaxial cables, which are thick. You can clearly see them running into or along the walls where the camera is mounted to a digital video recorder. These cables do not have audio functionality. Ethernet cables do and are easy to spot because they are thinner and flat. However, keep in mind that hybrid coaxial cables look similar to coaxial cables and have audio-transfer capability, which may complicate identification.

How Far Can Security Cameras Pick up Audio?

A few factors impact how far security cameras can pick up audio, including:

• Microphone quality: The quality of the sound depends on the quality of your microphone. Most home security systems can pick up sound within 15 feet of the camera.
• Ambient sounds: If the camera is situated in a place with a lot of noise or ambient sounds, the location can affect how far and how clearly you can hear sound in the recording.

Following the Laws Involved With Recording Audio Using Security Cameras

There are reasons why most security cameras don’t have audio — in many states like Massachusetts, it is illegal to record sound without the explicit consent of all involved participants. This includes Wi-Fi recording. Here are a few factors to consider regarding the law, security cameras and recording audio.

1. All-Party or One-Party Consent

Certain states require only one-party consent for sound recordings, while others require explicit permission from all parties before you may record audio.

One-party consent states require only one person on the recording to give permission for audio to be saved. As long as someone present during a recorded discussion gives consent, it is permissible to record the audio of other participants.

Two-party consent states require everyone on the audio to give explicit permission to be recorded. States that call for two-party consent include:

• Massachusetts
• New Hampshire
• Connecticut
• Pennsylvania
• Washington
• Florida
• Illinois
• Maryland
• California
• Montana
• Nevada
• Delaware

All other states are one-party consent states.

It’s advisable to familiarize yourself with the security privacy laws of your area. It’s better to be on the safe side, even in one-party consent states.

2. Privacy Laws

Reasonable expectations of privacy exist in every state. Most people expect bathrooms, bedrooms and private spaces to be free from cameras and audio recording devices. In the workplace, communal areas like break rooms and bathrooms should also be free from audio-visual recordings. If you record people in these areas without their knowledge and consent, you could face massive fines of $250,000 to $500,000 or even a five-year prison sentence.

Privacy laws apply to Wi-Fi or IP cameras as well. Before recording anyone, remember that you should always consider:

• Privacy: Nobody is permitted to record video in areas where people expect a high level of privacy, like bathrooms, bedrooms and toilets.
• Audio: Recording video with sound can contravene wiretapping laws.
• Transparency: Make it clear and visible that you are recording people. Put up signs and don’t hide cameras unnecessarily. With proper communication, the presence of cameras can deter criminal behavior and help people feel at ease.

3. Surveillance Signs

For home security, putting up a surveillance sign is not a requirement. However, it is recommended — it can deter burglars and ensure your neighbors are aware of any communal areas, like sidewalks, that may be recorded by you.

Some states require businesses to put up signs indicating surveillance, especially in areas where people expect privacy, like dressing rooms. Each state has different requirements, so it’s best to ensure you know what to do to remain within the law in your area.

4. Expert Assistance

Security cameras may be able to record audio, but that doesn’t mean they are allowed to. Partner with the experts to avoid contravening any of the surveillance laws in your state by accident. Trained security camera installers can advise you on what is legal and offer you a professional solution that works for your business or residence.
