The ability of surveillance devices to capture audio depends on their configuration. Generally, surveillance cameras themselves do not have the capability to record sound. However, some cameras come with built-in microphones or support external microphones for audio recording. To achieve sound recording, you need to have a microphone device, whether it's built into the camera or externally connected. Furthermore, you require a Digital Video Recorder (DVR) that supports audio and video synchronization for simultaneous recording.
In most cases, street surveillance cameras do not record sound. This is because street environments are typically noisy, resulting in suboptimal audio quality, and pedestrians are constantly on the move, making sound recording less practical. Audio recording is better suited for indoor or specific outdoor scenarios in surveillance. By integrating audio capture into a video surveillance system, security personnel can engage in two-way audio communication with potential suspects and perform audio monitoring. From a video surveillance perspective, it's also possible to implement a standalone audio detection feature that can trigger video recording or alarms.
