So, let’s answer a growing concern among homeowners using security cameras that record audio: Is It Legal for Security Cameras to Record Audio?

It is legal for you to keep an audio-recording camera hidden to catch potential burglars. In addition, you can record a person in a public space without getting into trouble.

However, this is as far as it goes. Recording audio in private areas such as bathrooms, bedrooms, or dressing rooms without a person’s consent is illegal and violates eavesdropping regulations. 

Therefore, always get consent from people being recorded and be aware of areas where they have reasonable privacy expectations.

Also, read this article for more insight into the subject. We will discuss, among other issues, how to know if your security camera has audio recording capabilities and tips to follow when you have a snoopy neighbor taking advantage of the device.

Why Is Audio Recording Illegal?

While recording audio is becoming a standard, most people are not sure whether it is legal for their security cameras to record and store audio. Usually, the legality of the matter rests on whether the person being recorded is aware and the state’s laws concerning audio surveillance.

The Federal Wiretap Act forbids anyone from secretly recording conversations deemed private by another person. But the act does not apply if one person in the conversation consents.

In addition, the legality of recording audio varies by state. Most areas have specific laws governing the use of electronically recorded conversations. For instance, we have 11 states that need two-party consent for audio recording, while the rest only need one.

One-party consent means that if you’re part of the dialogue, you can record it, regardless of whether the other person knows or consents. But you have to be present for the conversation during the recording.

On the other hand, two-party consent means everyone in the conversation must know the conversation is being recorded and give consent. The following states need two-party consent for audio recording.

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

So, no matter where you are, please look into your area’s surveillance regulations before installing security cameras in your business or home.

Penalties for audio recording without consent also vary from state to state, and country to country. However, the punishment is more severe when you record audio without the other person’s awareness.

For example, it is a federal offense in the United States to record audio without permission in public. Further, with some audio surveillance regulations, the penalty can include up to five years in prison or $500

In other countries like the United Kingdom, the penalties are less severe. But you’ll still be fined up to £2,500 if you are caught recording audio without permission. So, always check the specific regulations in your country before recording anything.

How Do You Know If a Security Camera Is Recording Audio?

Nowadays, most security cameras can record audio. But the feature is not that obvious. You have to examine the gadget’s external body, google its model, check its app, or read the manufacturer’s specifications to verify. Also, you can play and see whether the recorded videos produce sound.

However, in multiple jurisdictions, an audio recording is a direct invasion of people’s privacy. As a result, it is your right to know whether you are under sound supervision by surrounding security cameras.

Thankfully, this section examines surefire ways to confirm whether a security camera has audio surveillance. They include

  1. Google the Camera’s Model.

This is a quick strategy to determine whether a security camera reads audio. It works best when you’re in a new work location and have no idea if the gadget records video only or both audio and video.

So, search for the security camera online if you want to know everything about it. For instance, search for Arlo Pro 4 review for an Arlo Pro 4 security camera. Also, you’ll see various websites reviewing the gadget. So, be patient and check its features.

Moreover, you don’t need to be sure of the security camera’s name and model number. Google allows you to upload the device’s image and search for its details. Then, you’ll verify if the camera has a mic.

However, be careful when doing your online search since you cannot trust everything you see on the internet.

  1. Look for Microphones on the Camera Housing.

This method is perhaps the easiest as it involves looking around the device and checking for installed microphones.

Most security cameras, whether outdoor or indoor, come with an in-built microphone to attach sound to the recorded footage. Sometimes, the microphone is concealed to keep anyone from detecting it.

The difficulty of getting the microphone depends on the camera type. For example, detecting the microphone on the wired and wireless dome or bullet cameras is straightforward.

These cameras have a black dot, similar to what you find on smartphones and headsets. But some brands have an audio iris, which is a small black hole in the middle. Thus, a careful assessment will answer your question.

  1. Play the Recorded Video of the Camera.

You can play the recorded videos to tell whether the security camera has audio capabilities. Usually, most cameras allow users to check footage by accessing a website or through an application. Thus, check if you hear sounds and noises from the recordings.

The only demerit is that this strategy does not work for surveillance cameras in public areas. Common people will not access the footage to verify if it has audio. So, you can only use the method to evaluate accessible cameras.

  1. Open the Camera Mobile App and Scroll.

This technique also works for security cameras you can access. But it is quite efficient as the manufacturer offers applications you can install on your phone. Open the application, scroll down, and adjust the speaker or mute icon.

Remember, the unit has two-way audio capabilities. You can talk from your smartphone or tablet and have the audio projected through the camera, meaning you can converse using the camera.

But some camera brands only allow the user to hear without speaking or answering back. Here, the security camera audio is blocked.

  1. Look at the Camera’s Monitor.

You can always know if a camera records audio by looking at its display monitor. You’ll see a red dot in the bottom right-hand or top right corner of the screen for video and a small speaker sign next to the video recording signs for audio.

However, this feature differs depending on the user interface on your security camera’s screen and the video recorder device. Network video recorders have different displays from digital ones.

  1. Contact the Camera Manufacturer.

Speak with the security camera manufacturer if the above strategies fail. Furthermore, the easiest way to verify what device you have is by asking someone who knows. So, contact the support team of the manufacturing company.

Also, this method may be the most straightforward. All you need to do is contact the customer support details and provide the camera’s name and model. Then, ask if it can record audio.

We encourage you to purchase your security cameras from a reputable company. This way, you are sure of technical support, whether on the phone or their website’s chat box. Moreover, you’ll not have to wonder which company produced your camera and its correct model name to get the correct information.

How Far Can a Security Camera Record Audio?

Most security cameras with decent microphones pick up audio from a distance of around 15 feet. If you want to record sound further from this distance, consider getting a camera with an external microphone.

Further, regardless of whether the microphone is external or in-built, the camera can record sounds from a 40-foot radius when in a quiet room.

However, complying with the laws of the state is prudent before recording audio outside your home. Otherwise, you are liable for breaking regulations if your camera intrudes on another person’s privacy.

What’s the Difference Between Surveillance Cameras and Security Cameras?

Regardless of how efficient you are as a business or homeowner, your eyes cannot be everywhere at the same time. As such, you need to incorporate technological advances for maximum security. 

Furthermore, security and surveillance cameras top the list for anyone looking to improve security. But multiple users wonder whether there is a difference between the two device categories.

Well, security and surveillance cameras differ in their purposes. For example, security cameras oversee multiple areas in a facility and require manning by on-site security personnel.

These cameras are visible and not under disguise since they are mostly used in public spaces. Moreover, they have no control over the targeted area and just record from their angle of view.

On the other hand, surveillance cameras record video footage for evidence. In addition, they detect movement in the specified zone, usually between 40 to 100 feet. But the distance lengthens or shortens depending on the system.

Security personnel operate surveillance cameras remotely and receive alerts through mobile applications, SMS messages, and other notification systems.

That said, let us examine each camera type keenly for more insight.

  1. Surveillance Cameras

These units are primarily found in public areas for continuous recording. Further, they work with security systems and can be installed in retail stores, offices, homes, and other places to deter criminal activities.

You can also use recorded footage from surveillance cameras as evidence of criminal activities.

Surveillance cameras utilize an IP network, connecting them from a remote system and transmitting the footage to a secure location. As a result, they offer a longer recording duration, ideal for surveillance.

However, the camera’s advanced features make them costly and complex to install. Besides, they need integration with complete security units, including video screens to monitor the targetted area.

Additional benefits of surveillance cameras include

  • They Deter Burglars. Regardless of being installed at home or the workplace, these cameras deter criminal intent. Burglars abandon their plan since they know that they’re being watched.
  • They Allow for Remote Access. Home and business owners can remotely monitor surveyed areas with an internet connection. Even better, no matter where they are, they can view the camera’s feed using a tablet, mobile device, or computer.
  1. Security Cameras

These gadgets are also called CCTV cameras and are installed almost anywhere, whether inside or outside a business or a home. They transmit signals from a specific location to a distant monitor.

Although some security cameras demand professional installation, others allow end-user mounting. Therefore, you can get a user-friendly unit and install it without incurring additional costs.

The best thing about these gadgets is that they only record footage after detecting movement. Hence, they conserve energy and bandwidth. Furthermore, their infrared light vision technology and advanced motion sensors detect movement anytime.

As such, security cameras guarantee high-definition footage and clear visuals. And you know exactly what you’re looking at. Even better, you can combine the devices with other security solutions like doorbells. So, you can converse with the person at your front door.

Additional benefits of security cameras are as follows

  • They Monitor Suspicious Movement. Security cameras are excellent for watching suspicious guests in your horse or area. Moreover, they observe various activities on your property, lowering the crime rate.
  • They Provide Evidence During Investigations. Security cameras gather evidence of expected or unexpected events. Thanks to their high-quality videos and audio, you can easily identify criminal perpetrators. 

Now that you know how surveillance and security cameras work, let us assess their primary differences.

  • Technology

Surveillance cameras monitor and control specific areas, typically comprised of a network. Further, they are mainly connected to IP networks, which connect remotely to a central location.

Conversely, security camera footage feeds from all the connected cameras. Then, it sends the recordings to receiving equipment like a monitor. Usually, this connection is made through a coaxial cable.

  • Functionality

Surveillance cameras monitor public areas from a distance and are usually visible and unmasked. However, the gadgets do not exercise control over the targeted environment. They simply record what is in front of them and send the video to a recorder, either through cable wiring or digitally.

In contrast, security cameras capture or record images and transmit footage signals to a Network Video Recorder (NVR), where they’re viewed and recorded. Further, these devices detect motion in the monitored zone and send alerts via a mobile application, email, or text message.

  • Application

Surveillance cameras are suitable for monitoring an environment and minimizing undesirable situations. On the other hand, security cameras manage the security of industrial and public property. Also, you can combine them with intrusion detection units for enhanced protection.

  • Features

Surveillance cameras transmit recorded video to an NVR using digital signals. You only need a single cable, which eliminates the need for many power cables. However, security cameras require cabling to send video feeds to a few monitors. In addition, the cameras should be strategically positioned in one location.

So, which system should you get for your facility and expect maximum protection?

Interestingly, the answer to this question depends on your security needs and budgetary requirements. For instance, surveillance cameras are excellent for larger businesses and public spaces. But they are pricey.

Besides, although 24/7 surveillance helps monitor everything that happens, they are easy to tamper with. Worse still, criminals can detect and destroy them.

On the other hand, security cameras are more affordable and versatile. Indoor and outdoor cameras can detect motion and see at night. In addition, they are HD-capable, which guarantees crystal-clear footage. 

How Do I Block My Neighbor’s Security Camera and Audio?

Living near neighbors has ups and downs. For instance, if you are sick and in trouble, they will offer quick help. However, not all people are kind, so you may have nosy neighbors who spy on you using security cameras.

Worse still, due to technological advancements in IP surveillance cameras, your neighbors can record audio and be privy to your private conversations.

Thankfully, if you suspect your neighbor is spying on your and want to preserve your family’s privacy, here are a few methods that will block their security camera audio and video.

  1. Talk to Your Neighbors

The first natural step is to express yourself to your neighbors and ask them not to record audio on their surveillance cameras. As much as it appears to be a tricky task, it is worth a try,

Be respectful and polite during the conversation and explain that you’re uncomfortable with them recording audio on their security cameras. Furthermore, a reasonable person should understand and consent.

However, if they insist on recording audio and refuse to change the camera’s viewing angle, you can try other methods below.

  1. Plant Growing Trees and Shrubs

Planting trees in your compound is an alternative if your neighbor does not listen to you. Moreover, if talking is not an option, this strategy works both ways.

Tall shrubs and trees hide your private rooms and windows from your neighbor’s security camera. They will also obstruct the device and your privacy increases as the plants grow and mature.

But this method does not work immediately if you do not have mature trees. So, consider using curtains as the plants grow.

  1. Get a Powerful Light-Facing Camera Lens

You can get intense light if you do not want to use blinds or curtains for this project. Moreover, this technique blinds your neighbor’s surveillance camera without causing damage.

Although the light does not help during the day, you can use a privacy film, for daytime protection. Then, preserve the light for nighttime privacy.

  1. Install Film On the Windows

Generally, window films are durable polyester laminate sheets that improve your window’s appearance and performance. You can install them to guarantee daytime privacy. But leave your curtains or blinds open.

However, you can see through your neighbor’s security cameras during the night if the lights are on. So, keep the curtains and blinds shut.

  1. Purchase a White Noise Generator

White noise is a sound produced by combining all the frequencies a human ear can hear. So, you get a sound similar to static on a radio or television.

In our case, we have a white noise machine producing the noise. This noise disrupts spying devices by making impossible-to-hear or less noticeable sounds. Therefore, your neighbor cannot comprehend what you’re saying.

Further, white noise generators create a static-like sound and cancel out other sounds. Thus, they are effective at blocking out conversations, confusing the surveillance cameras recording them.

  1. Use White Noise Mobile Apps

If a white noise generator is a waste of money and you’re afraid of investing, there is an alternative: white noise mobile applications.

Thankfully, we have multiple free white noise apps online. So, all you need is a smartphone or your preferred gadget to play it. And ensure the volume is high enough to cover conversations in your home.

  1. Invest in a Camera Jammer Device

A security jammer is another alternative. It silences security cameras and resolves the issue immediately. But the gadgets are extremely expensive and cost hundreds of dollars. In addition, they face state-based legality problems.

Security camera jammers block the camera filming and connections. They also disable video and audio communications and are not easily detected.

These devices interrupt and block wireless camera frequencies by sending interrupt-code signals between 900 and 2499MHZ. Thus, they quickly stop your neighbor’s security cameras.

  1. Always Speak in Well-closed Places

This method is perhaps the most obvious, but also the most effective. Ensure you have private conversations in a well-closed space to keep your neighbor’s security camera from capturing them.

This space could be indoors with all the windows and doors shut or outdoors in a view-sheltered location.

Should Security Cameras Be Above or Below Lights?

The rule of thumb for positioning security cameras is to keep lights out of view. So, install them below the lights. This lets the light flood the camera’s view without shining too directly and blinding it.

This recommendation also applies to extraneous lighting for visitors and pedestrians. They cause blind spots and compromise the camera’s images. In addition, the camera should be at a reasonable height to facilitate easy maintenance when replacing batteries.

How Long Do Security Cameras Keep Footage?

Most security cameras store footage for 14 to 30 days. This duration is perfect as it gives you enough time to review the recording in case of an incident. Moreover, it is not too long or unmanageable.

Some cameras have advanced features allowing you to download the recording to a local drive. As a result, you have more control over how long the footage remains accessible.

The quality or definition of the footage plays a critical role in how long security cameras store it. Remember, higher-definition recordings need more physical storage space. So, get the most suitable camera and storage option for your facility. 

For instance, a financial institution or large business needs more storage capacity. So, they need a device that stores footage for three months to one year, then automatically deletes the old recording to create space for new ones.

The security camera storage capacity depends on variables such as

  • Storage method used by the device
  • Additional installed cameras
  • The application used for camera storage
  • Number of cameras operating on DVR or NVR
  • Government regulations on footage storage
  • 24/7 recording schedule

Generally, most business owners prefer 24/7 surveillance systems for maximum protection. These units also guarantee high-quality images and have more storage capacity.

If owners want to retain specific camera footage, they can back up the older footage for future reference. Hence, even if you remove or overwrite live footage, you still have saved proof.
