The Perseid meteor shower peak is predicted to occur between August 11 to 13. There are a few pre-peak pings already audible. The activity should increase over the next several days.

Web streaming of the Perseid is on-line at: http://spaceweatherradio.com/

Quoting from their web page here is how they do it now:

The US Air Force Space Surveillance Radar has been shut down, but we're still recording meteor echoes. How do we do it? Radio engineer Stan Nelson uses a Yagi antenna in New Mexico to detect 54 MHz TV signals reflected from meteor trails. When a meteor passes over his observatory--ping!--there is an echo.
