The Song Meter SM4BAT-FS is a lightweight, compact Full Spectrum bat recorder designed to be left in the field for up to a month at a time without the need to change batteries. Sold here together with the SMM-U1 microphone and 3m cable.

Combining many of the features of the powerful SM3BAT with the size and compactness of the popular SM2BAT, the SM4BAT is ideal for bat and site surveys that require static monitoring, especially at remote sites. A rugged polycarbonate casing, integrated mounting bracket and weatherproof security cover ensure the unit stays dry whatever the weather.

The SM4BAT-FS generates high-quality, full-spectrum recordings that can easily be converted to zero-crossing recordings using Wildlife Acoustic's free Kaleidoscope conversion software.

  • Comes with built-in programs tailored for bat research.
  • Very simple to create customised schedules.
  • Longest deployment times on the market, thanks to a new low-power microprocessor and large battery capacity.
  • Deployment times can be extended with external power sources.
  • Effortless and affordable synchronization of multiple units, using a single GPS accessory
  • GPS accessory also records the unit’s travel path
  • The custom-built, lightweight, molded enclosure allows multiple units to be packed into a backpack. 
  • The weatherproof enclosure has an integrated, lockable security cover.

 You will also need D cell batteries, and an SD card (Class 4 or better).


2019 Update: Remote monitoring for Wind Farms

Wildlife Acoustics have recently added a remote logging capability to the SM4BAT-FS, designed for wind farm operators who need to know the status of their Song Meters.

This is only available on recorders with serial numbers greater than S4U06942 (manufactured from around March 2019) and running firmware 2.2.1. or later. You will also need an RS-232 data cable to connect the Song Meter to a data logger or other external system.

The new upgrade implements a serial communications interface to wind energy SCADA systems. The SM4-FS responds to serial requests with information including:

  • cumulative number of bat passes and pulses detected*
  • timestamp
  • voltage
  • temperature
  • flash card capacity
