I passed by an Arlo doorbell camera on a business near my place and just knew it was hiding some sound secrets, it was.

EMF from a doorbell camera
* not the actual doorbell in question.
I’m sure whoever was on the other side of this doorbell camera was wondering what the heck I was up to. In fact, when I am recording EMF I get a ton of weird looks but no one ever really bothers me. Bust out a microphone and everyone has questions.
Recorded with a Tascam DR40x and POTAR EMF Probe
