I did a PRE-move-out property inspection in April to see what needed to be done to RErent the property and when I gave entry notice to my current residents, they advised me that 1) they would be on vacation; and that they 2) had a camera system in their rental home with the recording feed viewable by the next door neighbor.
WHEW! I've experienced cameras on the OUTSIDE of a rental home; however setting one up on the inside a la NANNY CAM is a first for me.
Now that these residents have vacated the home they rent from me, I asked them for a statement that there were no cameras at the property. He sent me an e-mail which is fine for my request for a "statement" which I will keep with their lease documents.
I could have objected to the camera installation as an UNLAWFUL RESIDENT ALTERATION and a violation of their lease when I learned about it in April; however, they has bought a new house and were already moving....leasing AGAIN, may not be in their future so their e-mail statement will suffice and if something happens at the property in the FUTURE, I know where they ARE and how to FIND them.
...KNOWING when to REACT and the DEGREE of that REACTION is something newbie property managers and DIY landlords can ONLY learn through EXPERIENCE.....
