Many DAHUA cameras are equipped with built-in microphones or offer connections for external microphones, allowing for audio recording and monitoring alongside video footage. The audio recording provides additional context to the video, which can be invaluable for understanding interactions or detecting unusual sounds that may indicate security events. This feature is available in select indoor and outdoor models, making it adaptable for various applications. Users should be mindful of local regulations regarding audio recording, as it may be restricted in some areas. For locations where audio monitoring is permitted, DAHUA’s audio capabilities add a critical layer of security by capturing conversations or noises within the monitored area.
