Yes, CCTV (Closed Circuit Television) cameras can record sound, but not all CCTV cameras are equipped with audio recording capabilities. Whether or not a CCTV camera can record sound depends on its make and model, as well as the type of audio recording features it has.

Most modern CCTV cameras come with built-in microphones that allow them to capture sound, while others require separate audio recording devices to be installed in order to record audio. Some cameras also have the ability to record audio along with video footage, while others may only record audio.

It is important to note that in many jurisdictions, there are legal restrictions on the use of audio recording in surveillance, and these restrictions may vary depending on the country, state, or region in which the CCTV camera is being used. It is therefore important to check local laws and regulations before installing a CCTV camera with audio recording capabilities.

In summary, while some CCTV cameras can record sound, it ultimately depends on the specific make and model of the camera, as well as any legal restrictions that may apply in the area where the camera is being used.
