The Minimum Frequency and Maximum Frequency parameters set the frequency range in which the SMART will look for possible bat calls. If a signal contains components both inside and outside this frequency range, only the portions inside the range will be analyzed.
You should set the Minimum Frequency and Maximum Frequency settings to encompass the frequency range of any bat calls you plan on recording. These settings prevent signals that are too low or too high in frequency to be a bat call from triggering recording.
| Setting | Recommended Value for Bat Monitoring |
|---|---|
| Minimum Frequency | Slightly lower than the minimum frequency of nearby bat vocalizations |
| Maximum Frequency | Slightly higher than the maximum frequency of nearby bat vocalizations |
