This is what I use for exactly that purpose:https://www.biggerpockets.com/files/user/kubaf/fil...When I first do a walk through on a property I use this while I walk the property with my camera phone in hand to record the whole place top to bottom narrating the whole thing.  

I suggest you change the locks, give her keys, and have her buy some security cameras that she monitors through her phone.

Much better than what I currently have.I’ve actually thought about putting a camera up in the parking lot to capture how often the car is there.I’ll start with the written letter first reminding the tenant of the lease.

I just bought a new camera to do this with!

We are considering using a simplisafe system with door lock and exterior cameras for our STR that we are building.
