This is an audio surveillance kit consisting of a microphone and a PoE-powered interface/amplifier unit. The microphone is an omnidirectional electret type with a specified range of 25 feet, an adjustable gain, and features including a treble boost and limiter circuit. It operates on 12 VDC supplied by the interface unit. The interface unit provides an RJ45 network pass-through with support for IEEE 802.3af PoE (modes A and B), delivering 48-60V DC input. It contains a voltage regulator to power the microphone and provides an isolated audio output via RCA or a 3.5mm jack with adjustable output level. The microphone's frequency response is 200Hz to 16kHz, and its S/N ratio is >60dB. The physical dimensions of the microphone are 4.7" x 2.9" x 0.9" and the interface unit is 3.3" x 2.0" x 1.6". Operating temperature and ingress protection ratings are not specified.
