Surveillance cameras with audio jacks

 

— availability of audio input and/or output in the camera design. This feature makes it possible to work with sound, but the features of this work may be different, depending on the specific set of connectors. The audio input itself allows you to connect an external microphone, and the audio output allows you to output sound to an external device (for example, a recorder or amplifier with speakers) via a separate channel. At the same time, these connectors can be used one at a time. For example, a camera with a built-in microphone may only have an audio output, while a model with a LAN or Wi-Fi connection can transmit audio on the same channel, and audio input is sufficient for such cameras.
