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 built into a small Pelican case. 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 thumb-drives for storage.
Internally, the iFR-IV runs an embedded version of SPECT’R 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.
How it works: Connect the EXT microphone and plug in the optional LCD controller to the USB1 port. Plug in a storage device (card reader) into the USB2 slot. Upon booting the iFR-IV, the typical settings should be reviewed, such as date, time, trigger setting, and timer options. You can also enter custom filenames and even SonoBat compatible metadata notes about your sampling location.
Unplug the LCD controller and the iFR-IV sleeps until the next programmed monitoring event occurs. A log file is written to your storage media along with SonoBat compatible .wav files.
The iFR-IV is best at:
- Overnight or longer duration unattended recording
- Situations where very long cable runs are required
- Built in networking; suitable for deployments where you would like to remotely access the data
