The iFR-IV is an integrated field
recording system developed for overnight and extended duration
monitoring projects. Drawing just 3.2 Watts, the iFR-IV is Binary
Acoustic Technologies lowest power recording solution. It is capable of
recording up to three days using the internal battery and up to two
weeks using a small 40 Ah external car battery.
A complete monitoring system can be assembled using
a minimum of components. A typical overnight recording system consists
of an iFR-IV Field Recorder along with an ultrasonic microphone. The
system can also be reconfigured into a extended duration recording
system by adding, a USB hard drive, and a solar panel.
The iFR-IV is a fully weather proof system. It
includes an integrated battery system, an embedded microcontroller, a
high speed 16-bit digitizing system and two USB connectors which allow
it to control and operate an ultrasonic microphone along with a
combination of external USB hard-drives, Compact Flash writers, or USB
Internally, the iFR-IV runs an embedded version of
SPECTíR software. It supports an operation timer, the WAVPACK loss-less
compressed file format, sleep mode to conserve battery power, a file
scrubber to reduce noise-only files, and a
remote file transfer mode that will automatic transfer recordings back
to a specified FTP site.
The iFR-IV operates using Binary Acoustic
Technologies EXT ultrasonic microphone units. The microphone interface
supports cable lengths of up to 250 feet.
