What is a CCTV Microphone?

We come across them in our everyday lives a lot, but often do not think about what they are. A microphone is a device that captures sound waves and converts them into an electrical signal, which is then saved, played back, or amplified.

In terms of a CCTV Microphone, they are capturing sounds that will be used in tandem with video signals to prevent and deter crimes from happening on a business or private premises. 

Utilising both audio and video creates a much stronger security system and can lead to more information for identifying criminals, stopping crimes, and general surveillance. 

Different Types of Microphones for CCTV 

Technically speaking all CCTV microphones serve the same function, recording audio to be used as part of a 2-part surveillance strategy (audio and video). 

With this being said there are two core types of microphones for CCTV, internal and external.

Internal CCTV Microphones

Typically speaking you might not even know this is in your camera as it will not be physically visible. These will be manufactured within certain types of cameras, for instance, most IP Cameras will have a mic included.

Internal Microphones are often included on more expensive CCTV cameras but do offer a more compact solution to your surveillance.

External CCTV Microphones 

The opposite is the external microphone which comes separately from your CCTV camera and can be linked to it to provide both audio and video. Depending on the models they may connect directly to each other or via your installed DVR (or NVR).

Microphones are often easy to install, especially if there is a dedicated audio port on your CCTV cameras. Most will probably use an RCA Cable, but there are a lot of different connectors.

Note – All of the microphones on this list are external as we are looking at pairing them with cameras that do not include one.

How Does a Microphone for CCTV Work?

As we have alluded to above, microphones work by converting raw sound waves into audio files that can be used for surveillance and security.

Without trying to get too technical, the microphone works using a diaphragm that vibrates when sound waves hit it, which in turn moves a magnet next to a coil. 

So in short, a microphone for CCTV works when sound creates vibrations that are converted into digital signals which are then saved as audio files.

A less common microphone type is a wireless microphone. Instead of transferring data via cables, they utilise a radio transmitter that can wirelessly transfer data via a network connection or proximity.

What Do You Look for in the Best Microphones for CCTV?

Knowing how to decide on a microphone for your CCTV system will help you make the best choice for your business. Below we are going to look at some different things to look out for when making your decision. 

Sound Quality 

This may seem like an obvious thing to look for in your CCTV Microphone, but it is often overlooked. All mics will pick up sound, that is a given, but it is how they pick it up that is important.

Capturing usable sound is what you should be aiming for. To put this into context, let’s say you set your CCTV up outside your building, factors like wind and rain may limit the end sound quality in a lesser mic.

Capture Radius 

Often CCTV cameras are used to capture footage (or in this case audio) across a large area, so finding a microphone that can cover the same radius is important. 

It is no use having a camera that covers a wide range if your mic only picks up things within a few metres. Obviously there are a lot more variables that affect if your microphone can detect the audio, but finding one that has a good capture radius can help you determine your choice. 

CCTV Microphones Fact

Price Point

Most business decisions will end up being made on a certain allocated budget. This typically means that you have to find the best options within your price range. 

For CCTV microphones there is not a huge variance in pricing, which makes this an easier decision to justify even the higher end models. However, higher prices do not always mean better quality.

Technology

Finding a mic that has all the bells and whistles might not be your top priority, but there are some features that can make them a much savvier purchase. For example, some mics can reduce background noise and only capture louder noises.

You would be surprised how elaborate some of the technology within the CCTV microphones can be, everything from echo reduction to weatherproofing, to increased coverage.

Sensitivity 

The sensitivity of your microphone is a factor that might help you pick the right model. For some businesses you may want a very sensitive mic that can pick up very quiet noises, and for some it may not be as important.

The outdoor vs indoor debate often helps you decide the model you need to look at, as they are very different environments, which require different mics.

Weatherproof

Finding a CCTV microphone that is weatherproof could be very much make or break depending on your situation. If you are using your microphone for an indoor camera then you will be less inclined to buy a durable model.

On the flip side, if you have an outdoor installation, then you will want to find a microphone that can handle the environment, be that rain, wind, or durability against the elements. 

What is important to you will ultimately affect which microphone you choose to buy for your CCTV camera, but hopefully, these factors help you make the right decision.
