ClearView have been manufacturing and supporting Analogue and Digital CCTV Decoding Solutions, around the world, since 1996 when they introduced “Unimux” – the world’s first “universal” video de-multiplexer.Read More
Since 1996, ClearView have manufactured and developed a unique range of miniature self-contained microphones, delivering outstanding audio quality for difficult applications including interview, custody and covert recording.
Our range of security microphones is extensive and includes the following microphone types:
- Body worn
- Interview recording
- In-built into CCTV camera
The need to record crystal clear sound, in addition to camera images, is a necessity for applications like:
- Interview rooms
- Custody suites
- School classroom recording
- Reception desks
- Bank, railway station and post office counters
The MPA110 series of microphones includes a unique in-built amplifier for connection directly to a digital video recorder (DVR) or audio recorder.
The miniature MPA110 series house an omni-directional microphone, phantom power supply, pre-amplifier and line amplifier in a self-contained vandal resistant or wall plate format. The vandal resistant unit is smaller than many stand-alone microphones measuring only 38W X 25H X 72L mm. It may be wall, ceiling or desk mounted. A body-worn version is also available.
The line level output offers the additional benefit of a robust audio signal, unlikely to be affected by radio signals or interference. Since the unit is powered by 12VDC, it may also be battery powered.
The microphone amplifier is an ultra low noise module. A preset control gives gain control from 35dB to 75dB.
