We own a property that abuts to a multi family rental property. Someone(s) periodically toss trash over the fence. It's a 10+ foot tall fence and the building is over 6 feet away from the fence, which means it couldn't accidentally fall or come over by mistake.

For the most part, it has been small stuff - empty can of soda, misc. rubbish etc. I've either just picked it up or tossed it back over. Yesterday a 4 foot metal rod came over the fence, this could easily have hurt someone.

What I have done so far

• Put up a second camera with a view of the entire fence (Unfortunately, the rod landed slightly outside the field of vision of the first camera, so I added this one)
• Set up motion alerts for all the cameras
• Attempted to contact the owner of the property (not been able to connect thus far)

What would you do?
