EVP Entity Responding

I was sitting in the chair (thats out of sight of the camera) waiting for my dog Keisha to relieve herself, when I could sense someone around. So, I softly acknowledged their presence (01:45:20 time stamp) and someone responded with “hello” (at the 01:45:25 time stamp), than a strange click (01:45:29) and then a sound like someone whacked my fence immediately after. However, upon reviewing both cameras, I see nothing to explain the last sound.
This is a stitched video of an audio enhanced (50 decibels) video and slowed clip.
