Sharing is caring!

Security cameras are a great way to add a layer of protection to your business or home. Many business owners often ask, “Can I record sound on my business CCTV system?” After all, you can record audio on your home security system (with some exceptions).

Can I Record Sound on My Business CCTV System?

If you’re simply wondering if CCTV systems are able to record sound in your business, the short answer is yes. But whether a camera is equipped to record audio compared to whether it’s legal to record audio in your business is a bit more complicated.


Technically speaking, many CCTV camera systems are designed to record audio. This is accomplished by adding a microphone to the camera system or installing a camera with a built-in microphone.

IP cameras have the advantage of using Power over Ethernet (PoE), which can also power a microphone. This eliminates the need for an extra power cable and makes installation simpler.

Analog CCTV cameras typically do not have audio capabilities. Analog cameras use older technology and are gradually being phased out in favor of IP cameras. If you have an analog CCTV system and want to add audio, you’ll need to replace your cameras with IP cameras or install a separate microphone system.


Adding audio recording may seem like a fantastic enhancement to your CCTV system. Any indoor or outdoor camera that is properly equiped can record audio, but it may not be practical in reality.

Storage space is a significant consideration. Audio files add to the overall data transfer and storage space needed to store video camera footage. You’ll need a larger storage system or will have to delete audio files more frequently to make room for new ones.

Another practical consideration is the quality of the audio recording. Microphones don’t always pick up sound evenly, which can result in muffled or difficult-to-understand recordings. Background noises, such as the hum of air conditioning or traffic, can also interfere with capturing clear audio. For these reasons, many businesses choose not to record audio with their CCTV cameras.


The legal implications of recording sound in your business are much more important than the technical or practical ones. After all, using a CCTV system to record audio may violate several privacy laws. Audio recording laws vary from state to state, so it’s important to check the local regulations before you set up your security system in your business

Businesses are subject to state and federal laws about recording sound with their CCTV security systems. In general, state laws allow recording audio if at least one person involved in the conversation consents to the recording. This is where the phrase “one-party consent” comes from. Some states require all parties to consent to be recorded, even in a public place.

Employers are also not allowed to listen to or record conversations of their employees without consent, especially in places where employees have a reasonable expectation of privacy (i.e. offices, locker rooms, restrooms).

Violating audio recording laws can result in significant penalties, including fines and jail time. In some cases, businesses have been forced to shut down due to illegal audio recordings.

If you plan to use your CCTV system to record sound, you should check your state laws to make sure your business complies with laws governing recording sound.

What is a CCTV System and What are Its Benefits?

A CCTV system, or closed-circuit television system, is a type of security camera setup that is often used in commercial and industrial settings. You can use a CCTV systems to record video or take pictures of an area.

The primary benefits of using CCTV systems are that they help deter crime, catch criminals in the act, and provide peace of mind to customers and employees. Companies can also use CCTV systems to monitor employee productivity and catch errors or accidents in the workplace.

For example, if you have a retail business, you may want to use the footage to identify which products are being stolen the most. This can help you with loss prevention and improve security in your store. Additionally, if you have a manufacturing business, you can use CCTV video to help improve your production process.

The Benefits of Adding Audio to Your CCTV System

There are several benefits to adding audio to your CCTV system. Identifying criminals is probably one of the most obvious benfits. Sometimes its not always possible to idenfitfy someone by video alone. Audio recording of the person’s voice can help to idenfitfy them when the video might not be clear enough.

Monitoring employees is another benefit of adding audio to your business CCTV system. You can hear conversations to see if employees are discussing company secrets or if they’re engaging in illegal activity.

You can also use the audio to improve customer service. For example, you can listen in on conversations in your retail store to see if customers are unhappy with the customer service.

CCTV with One-Way “Listen-In” Audio

Security cameras with listen-in audio have a built-in microphone that can record audio. The audio is one-way, meaning you can hear what’s happening near the camera, but the people in the monitor can’t hear you. This means you can’t use one-way audio cameras to speak with the person on the other end.

CCTV with one-way audio is useful for a few reasons. First, it can help you identify criminals if the video footage isn’t clear enough. Additionally, one-way audio can also be used to monitor employee conversations and improve customer service.

CCTV with Two-Way “Talk-Back” Audio

Security cameras with two-way audio have built-in microphones and speakers that allow the user to listen to and record audio and also talk to the people being recorded.

CCTV with two-way audio is useful for a few reasons. First, it can be used to deter crime. If a burglar is trying to break into your business, you can use the two-way audio to speak to them and hopefully scare them off. Two-way audio can also be used in your business to provide customer service or give directions.

The Disadvantages of Adding Audio to Your CCTV System

Adding audio to your CCTV system can come with some disadvantages, too.

Legal Concerns

Legal compliance is perhaps the biggest concern with adding audio to your CCTV system. From state to state, there are laws that prohibit recording audio without the consent of the people being recorded.

Recording audio might seem like just another common feature of any security system. But you should always check your state laws before adding audio to your CCTV system to make sure you’re not committing any violations in your business.

Privacy Issues

Privacy is another big issue when adding audio to your CCTV system. Even with gaining consent from people being recorded, the legal concept of reasonable expection of privacy in protected areas.

Recording is against the law in certain places such as bathrooms, locker rooms, and changing rooms. Reasonable expectation of privacy also protects employees from unreasonable intrusion into an employee’s areas of seclusion.

This means you cannot surveile an employee in their office for sure. But an employer also cannot video or audio record employees in common areas such as break rooms, hallways, or parking lots.

Intrusive audio recording in these types of areas may be considered an invasion of privacy, even if you have consent from the people being recorded.


Another potential disadvantage of adding audio to your CCTV system is the cost. Audio-enabled security cameras are typically more expensive than regular security cameras.

You’ll also need to factor in the cost of installation and any monthly fees associated with the audio service.

CCTV cameras cost anywhere from $70 to $340 per camera, including installation and setup. Adding audio recording costs an additional $10 to $30 per camera. Overall setup for security systems without cameras can cost anwhere from $600 to $2,000, so you can see how adding cameras and audio recording quickly increases the price.

Storage Space and Bandwidth

Audio files require additional storage space and bandwidth compared to video files alone. You’ll need to factor in the extra costs associated with storing and streaming audio recordings.

A typical high definition security camera needs about 1 megabyte per second (Mbps) of bandwidth to stream video. But when you add audio recording, that number jumps to 3 Mbps.

That same camera needs storage space of about 3 to 5 gigabytes (GB) per day, but with audio recording, you’ll need storage space of 9 to 15 GB per day.

Businesses with limited storage space or bandwidth can quickly find themselves paying for expensive upgrades to accommodate the audio recording feature. So, if you plan to add audio recording to your CCTV system, you’ll need to factor in the additional costs of storage space and bandwidth.
