Yes it can, works like a thermal camera. No recording (apart from stills), but you can watch the video image and, depending on overlay options, new sounds will be localized on the screen. Use mine to track down air leaks in a compressed air system, thing is magic.

That should work. You could always have Claude Code run the server itself and explain to it the rough parameters of the sound (two seconds, late at night) - then let it listen for hours and occasionally tweak its own configuration to try to better capture what's happening.

In my case it identified that the likely beep was about every 62 seconds pretty quickly - then I confirmed that one of the recordings was the mystery sound and it locked in from there.
