Hi,
We recently moved into a lovely new home. In recent weeks, we've noticed a high-pitched sound coming from somewhere nearby...
Maybe twice a minute, all day and night, we can hear any of a number of beeps; one long beep for a couple of seconds, or anything up to four shorter beeps in a couple of seconds. There's plenty more houses close by on all sides, though it's hard to tell what direction it's coming from. It's not loud, but loud enough to hear from inside if the windows are open and the house is quiet.
If anyone has any clue what it might be, your help is much appreciated.
Thanks in advance,
K
