AXIS T83 Microphones are discreet top-quality microphones very reliable even in demanding environments. The series comprises of omnidirectional condenser microphones, AXIS T8353A Microphone 3.5 mm and AXIS T8353B Microphone Phantom Power. They are capable of handling sound pressures of up to 138 dB (max SPL), have a sensitivity of -44 dB (relative: 1 V/Pa) and have a high Signal to Noise Ratio of 68 dB (relative: 1 kHz @ 1 Pa, 94 dB SPL). An outstanding dynamic range of 97 dB allows for recording of complex scenarios.
AXIS T8353A has a 3.5 mm adaptor, compatible with Axis M-, P- and Q-line network video products supporting a 3.5 mm jack for microphone input.
AXIS T8353B Microphone Phantom Power is an omnidirectional microphone with an XLR contact and a pigtail adaptor. Phantom power voltages of 12-48 V DC is supported. It is compatible with phantom power devices, such as AXIS P8221 Network I/O Audio Module.
The design of the AXIS T83 Microphones allow for discreet and flexible installation. The microphones can be used for covert audio detection or as a complement to an indoor video surveillance. An interrogation room can be a typical surveillance scenario where good audio quality is a key factor. The room can be located at a police station, customs office, detention or at a social office. Another scenario can be at a bank or a postal office where the microphone is used for surveillance.
Audio detection may be useful to a security operator interested in listening to what is happening at a specific location in order to evaluate the urgency level in a situation, e.g. a sound of fighting, screaming, slamming doors or gunshots. Audio communication can also be a third scenario, where a network camera with the microphone is used to communicate as an intercom system.
