About this product

The Song Meter SM4BAT ZC is a robust and weatherproof single channel recorder which records bat calls in zero crossing format. Powered by four D-cell batteries it will record for up to 700 hours in the field, depending on bat activity. The SM4BAT ZC has slots for two SD cards providing storage of up to 64GB using SDHC cards or 512GB with SDXC cards. 

Scheduling functions allow you to set the detector to record continuously or to use complex schedules based on specific times of day or relative to sunset and sunrise. You can also tell the SM4BAT ZC on what day you would like it to begin recording, or whether to begin immediately. Your inputted schedule will then be repeated daily until you stop it or until it is limited by battery life or memory space.

A mounting bracket at the top and bottom of the unit provides a sturdy way to attach the recorder to a tree, post or other suitable surface. The front of the unit also fastens securely and can be padlocked to prevent tampering with the interface. 

A separate GPS module can be purchased to use with the SM4BAT ZC which will let you synchronise time and date settings as well as calculate accurate sunrise and sunset times. 

The SM4BAT ZC comes with a three year warranty.

The SM4BAT ZC is also available as a Complete Bundle. This includes the SM4BAT ZC, SMM-U1 microphone, four D-cell batteries and two 32GB Class 10 SDHC cards.
