Hello - I have a pretty unusual request, but I hope you'll bear with me,
I'm a researcher studying sea lion vocalizations for a project that could help elucidate the chemical causes of autism. One of the requirements of this project is long-term, remote audio and visual monitoring/recording of a pen of sea lions. I thought of myself as pretty competent with A/V issues, but I'm running into a few problems that have humbled me quite a bit and reminded me of just how much there is to know in this field.
I need to be able to:
*record continuous, synced and/or timestamped audio and video.
*the audio must faithfully record vocalizations up to 20 kHz.
*transmit that information in real time to a computer in the lab, 2,000 miles away.
(The recording site also has power outlets and internet; this isn't in the middle of the ocean or anything)
How would you solve this problem? Do I purchase a video encoder/server designed for security monitoring and/or network video recorder? The problem with these is that all the audio-enabled models I've come across only record up to 8 kHz. Do I transmit the audio separately, and if so, how do I do it in such a way that I can sync it up with the video?
If you're handy with more rudimentary audio issues, please do take a look at my sister post in the Audio theory board, entitled "frequency loss in XLR -> 3.5mm adaptors."
Thanks so much for your help and advice!
