(meteorobs) Anyone doing infrasound monitoring?

I have started 24 hour continuous all-sky camera video monitoring for 
fireballs in conjunction with my forward scatter radio array.  I 
monitored for daylight fireballs some years ago and would check my video 
at times of strong radio fireball receptions but discontinued that 
regimen as I was never able to discern a daylight fireball in the midst 
of sunlight. I did spend some hours at it.

Also, by some quirk of radio meteor observing there can be a tendency of 
certain low velocity, deep penetrating fireballs that some do not 
register strongly on radio spectrographs.  In any case I am back to 
recording all day and checking the video at times of fireball hits.

But, over the course of the year I occasionally hear sonic booms during 
the day and wonder if some of the booms might be fireball generated. ?? 
   This then makes me wonder about infrasound monitoring in conjunction 
with video/radio.

Does anyone do infrasound meteor monitoring?   Can a research-grade 
infrasound system be manifested for little money?

Thanks in advance for any info.
