Two-way audio adds communication functionality to the V380 Smart Dual Bulb PTZ Camera. Models equipped with a built-in microphone and speaker allow users to listen to the monitored area and communicate through the camera using the mobile application. This can be useful when someone arrives at an entrance, when checking on family members, or when communicating with staff in a shop or office. It can also provide a convenient way to speak to someone without physically moving to the camera location. The feature depends on the specific model and network connection, so users should verify the exact audio specifications before purchase. When available, two-way communication adds another practical function beyond ordinary video surveillance.
