Harpoon Micro GSM Audio Transmitter

Maxsur's Harpoon Micro GSM audio transmitter features worldwide operation with true quad-band compatibility. It's ideal for bodyworn use, vehicle or structure insertion.  Easy to use features makes this advanced transmitter ideal for both short and long term critical operations. Right out the box, this GSM transmitter can be placed into operation in just minutes. It works with nearly any SIM card and because it is compatible with US cellular carriers, you won’t get systematic dropouts common to GSM devices from Asia.

The onboard DSP (Digital Signal Processor) produces high quality evidence with ambient noise reduction, echo cancellation and selectable high & low frequency noise filters. Microphone sensitivity has three level adjustments and can be configured with dual microphones for pseudo-stereo. Each microphone can be remotely enabled/disabled making it useful to cover a vehicle interior and then later, vehicle exterior with the secondary microphone. The GSM transmitter has a sleek profile of just 0.41” which is easy to conceal under clothes, trim panels, junction boxes and more.

When active, the transmitter consumes a minute 60mA and only 30mA in sleep mode which allows for days of operation using common alkaline batteries or indefinite operation when powered through vehicles and buildings. For long term operations, this transmitter can be easily programmed to activate & auto dial upon detecting noise (user selectable detection level) or be programmed to activate when the built-in accelerometer detects movement (9 selectable detection levels). Maxsur's Harpoon includes an integrated cellular antenna, high gain Knowles microphone, voltage adaptor for use with 7 to 28VDC power and a waterproof carrying case.
