1 hour recording only!

Hi there, I am a technician and have been tasked with finding out why these 8 units only record for an hour max. I am completely new to these units and have just downloaded the configuration app and had a play. I set the time and a schedule but not any success in getting the unit to record anything. Does a mic need to be attached to record sound or is there an onboard mic? I tried on default also presuming constant recording. My understanding is they just require 8 hours continuous recording, any assistance welcome while I try to get to grips with these units. I have fitted brand new Alkaline batteries and am using a supplied sd card. Also, can I just play any recorded sound on PC as a WAV file or do I need further software?

Hi, set a schedule to record for 8 hours but still only got 1 hour's worth of recordings, any help would be greatly appreciated?

Hi Mwanga,

The firmware is a slightly older version but that should be okay. The configuration looks fine. The AudioMoth battery voltage looks fine. The fact that it actually goes beyond one hour and makes the recording at 5280488,2024-09-12T16:23:00+01:00 make me suspect the SD card rather than the AudioMoth itself. What was the device doing when you finally stopped the test? If a recording error had occured it would have been flashing both LED every two seconds, rather than just flashing the green LED between recordings. Can you post a picture of the SD card that you are using. I think the card may be full. Reformat it and try again. Deleting files often creates hidden files on the SD card that continue to take up space. AudioMoth is not able to remove these hidden files whilst recording WAV files, so it is always best to reformat each time prior to deployment.
