The 210 Omnidirectional Security Installation Microphone from Astatic is a miniature boundary microphone designed to capture ambiance in security, monitoring and observation applications. The microphone's low-profile keeps it hidden from view and a built in limiter tames sound pressure levels and improves intelligibility.
The output level is variable from -50 dBv (3.2 mV) to -10.5 dBV(300 mV) @ 1 μBar which is designed to interface with security cameras, digital video recorders and other observation and recording devices. Astatic 210 requires 8 to 18 VDC power and the connection is made through a removable terminal block plug.
