Why add a microphone to CCTV?

Adding the microphone to the surveillance camera significantly increases the recording value — the sound can provide additional information about events that the video itself may not capture. With audio modules for IP or analog cameras, you can record voice, ambient sounds and even communicate in the system.

Types of CCTV microphones available at MikaShop

• Electric exterior microphones: sometimes with a housing resistant to atmospheric conditions — e.g. TWA-MIC-ECT -54 dB. :contentReference[oaicite:0]{index=0}
• Audio modules (microphone + preamplifier): allow convenient connection of the microphone with audio input in the camera or recorder. {index=1}
• IP Microphones: designed for IP cameras with audio input — e.g. sensitive RTX microphones. {index=2}

Benefits of using microphones in monitoring

• Fuller situation picture: You not only record images but also sound — useful for incidents or thefts.
• Audio analysis capability: In conjunction with the recorder or VMS software, you can use sound detection (e.g. scream, glass shatter).
• Two-way communication: In some systems you can speak via the camera (built-in microphone + speaker).
• Improved event identification: The sound often explains what happens on the recording — such as steps, voice, mechanical noise.

What should we pay attention to when choosing a microphone?

• Sensitivity and frequency transfer: It is important that the microphone "collects" the sound clearly, but at the same time does not "send" the recordings.
• Impedance/exit type: Check that the microphone is compatible with the audio input on your camera or recorder.
• Power supply: Some microphones require 12 V DC, others can be powered by an IP camera.
• Microphone housing: If you mount a microphone outside, choose a weather-resistant model.
• Installation: Note the length of the microphone cable and the method of installation (e.g. on the camera housing).

Frequently asked questions (FAQ)

Can any CCTV camera record sound?

No — the camera must have an audio input (or microphone input) to connect the external microphone. Some IP cameras have this input by default, others require an additional module.

Does the microphone impair image quality?

No, the microphone only affects audio recording. There's no impact on camera video quality.

How can I connect the microphone to the recorder?

Connect the microphone cable (e.g. RCA) to the audio input in the recorder or use the audio module if the camera has a microphone input.

Does the microphone need separate power?

This depends on the model — some microphones require an external 12 V power supply, others can be powered directly from the IP camera.
