Anyone else stay in the marital house during divorce and install security cameras?

Wife filed a PFA against me a few weeks ago: she had moved out 9 weeks ago now. She still has stuff in the house: Thursday she and her brother show up unannounced, walk right in, then she walks right into the bedroom where I was without a knock or anything. Sent me into an instant panic attack, I called the police and they sent someone out (so she couldnt lie about anything) and stayed on the phone with my mom the whole time.

Im installing security cameras all over the house now so I can make sure she doesnt take anything else of mine and so I have footage of if she comes back again. Feels really paranoid though.
