Gianni,

You will still greatly benefit from a simple handheld heterodyne bat
detector so you can hear the bats in real time so you know what's flying.
This works by dropping the frequency by an adjustable amount which usually=

shows on a display. The call frequency and type of call gives a very good
indication of the species.

There are two detectors illustrated on:
https://en.wikipedia.org/wiki/Bat_detector
but a very popular one is the Batbox Duet
http://batbox.com/duet.asp
which also does a crude divide by 10 so you can use an audio recorder. This=

is also cheap enough to risk leaving running unattended.
