Can Security Cameras Record Voice?
You may have noticed that there is hardly ever sound if you have watched footage from a security camera being played. Why is that? Can a security camera record voice? Is it legal for a security camera to record audio? In this article, we will explore how security cameras record audio. I will also explain why or why not it is legal for security cameras to record audio. There are some cases where you need not just to monitor visual activity for your security but also the recorded sounds. If that is the case, you should read on to get a better understanding of your options.
It Depends on the Type of Security Camera
There are two main types of security cameras: IP CCTV and analog CCTV. Both can record audio, but they use different technological processes to input audio. So the answer to “can security camera record voice?” is yes, but it is not a simple, straightforward matter.
An IP CCTV or an Internet Protocol closed-circuit TV camera has the audio fed straight into the camera. In the IP CCTV’s system, the transmission type used between the microphone and the camera is analog. The transmission is turned into a digital format when the audio hits the camera level. After digitization, the camera sends a digital signal transmission to the network video recorder or NVR. An IP CCTV system can use several microphones at once.
Meanwhile, an analog CCTV does not use a digitization process. Instead, the audio is directly connected to the digital video recorder or the DVR, which is a device separate from the security camera. The DVR turns the inputted information into a digital format. An analog CCTV can also use many microphones at once.
Another factor that affects how can security camera record voice is the audio range. The quality of an audio recording will depend on the proximity of the source of the sound to the microphone. Security cameras are usually placed out of reach, and unless the location is very quiet and the source of the sound is loud, you cannot be sure you will get a crisp and clear audio recording.
A good average distance is 6 meters. This distance can pick up casual conversations, even outdoors, where there are more sources of noise. Make sure you test out your security camera’s audio range and how it would do in different conditions that could impact the quality of the audio recording.
Is It Legal for Security Cameras to Record Voice?
The main reason why security cameras do not record voice, even when they are technically able to, is because of privacy laws and consent.
Privacy laws vary from state to state. Audio recording without somebody’s knowledge is sometimes legal in one place, but illegal in another. It also depends on the situation or setting. In a workplace setting, it can actually be illegal for an employer to record their staff without the employee giving clear consent.
In general, these three rules are good to keep in mind no matter what state you live in:
- It is illegal to record audio when using video surveillance.
- Recording audio via Wi-Fi can lead to cybercriminal charges.
- Audio surveillance laws depend on state laws.
Always research regarding privacy laws and surveillance before you think about allowing your home security system to record audio.
Meanwhile, even though it can be technically legal in your state to record voice, you should also consider consent. This is especially important in the workplace setting.
Any time an employee is being recorded, through video or voice, they should be informed. The employee should also be given a chance to give their consent. If they give clear and proper consent, then they may be recorded. Otherwise, they cannot be recorded. However, there are some cases that allow for audio recording, but only when it is proven beyond a reasonable doubt that there was a need for a recording. The law will also have to determine that factor.
Even if you think the audio recording will remain private, you do not have full control of privacy and access. You cannot guarantee another person that their recording will not be disseminated without their consent.
