    Good Morning! Can I ask where the devices will be shipped from? Is it the UK or elsewhere outside of the EU? The reason for asking is that I'm trying to factor in UK custom charges. Kind Regards, G.

  • 9zi7mnmg normal

    Hello! We ship all EU orders to the Netherlands to be forwarded on. We will collect the VAT upon purchase.

    Hi. I want to buy 16 Audiomoths. But what will happen if the campaign deadline (30 September 2019) is reached but the target (500 units) has not been ordered?

  • 9zi7mnmg normal

    Based on some big orders that we know are coming, we really don't see that happening. In fact, we have not even added our internal order to this so I really wouldn't worry about it.

  • 9zi7mnmg normal

    But worse case, they will be available in our store if the campaign failed. I see a 0% chance of that this round though.

    Can this device be set to continuously listen to an audio frequency range and only record when there is a sound above a preset amplitude in that frequency range? I know this will sacrifice run time but it would be worth it to me.

    Hi Paolo, The device comes with recording schedule software, this currently does not have a trigger. However, the software is also open-source and triggering is possible with a bit of coding know-how. What frequencies are you interested in? Team OAD

    I would like to make a purchase with a purchase order from a University. Is this possible? If so, how do I do this through this website as the only option for payment is a credit card? Is there another way to make a purchase with a purchase order? Thank you for your help. - Kristina
