Yes, CCTV cameras can record voice and sound, but only if the specific model has a built-in microphone or an attached external microphone and the audio setting is turned on. 

How Audio Recording Works

  • Modern IP and Wi-Fi Cameras: Most newer smart home and business network cameras include a built-in microphone that captures audio and video simultaneously, digitizing the sound right inside the camera. [1, 2]
  • Traditional Analog Systems: Older or traditional analog CCTV setups typically record video only. To capture sound with these, you must wire a separate microphone directly into the Digital Video Recorder (DVR). [1, 2]
  • Two-Way Audio: Many modern cameras include a speaker alongside the microphone, allowing you to listen in and talk back through the device
