The T8351 Mk II Microphone 3.5mm from Axis Communications is a hemispherical analog microphone designed for spaces with low ambient noise. It picks up sound from every direction. The microphone is compatible with network devices that have a 3.5mm microphone input jack or a 4-pin audio connector (terminal block adapter available separately). Additional power supplies are not required for operation since the microphone is powered by the network device it is connected to.
This microphone is housed in an IP65-rated enclosure for protection from water.
