[MD] Tenant entering my bedroom without permission, cat cam picking him up

Some background info: I am 30sF, I own a home in Maryland and I am renting a bedroom to a 30sM tenant. It’s a shared kitchen/bathroom/living room and separate bedrooms. I have 2 cats so I need to keep my bedroom door slightly open for them to get in/out.

I became suspicious my tenant was entering my bedroom without my permission so I got a motion activated camera and put it on my bedside table pointing at my bedroom door. 10 minutes after I left the house the next day, I see him open my door, enter my bedroom, go to my bed to do something, and look towards the camera. Later on, he returns to close the door to the original position. I returned home and didn’t mention anything.

The next day I am home watching a movie downstairs. I moved the cam to my desk to get a better view of the door. While I am downstairs, I can now see him peeking through the door frame towards where the camera used to be. He is in full view because of the new position. He enters my room a few feet and stands there for 30ish seconds just looking around my bedroom. He again looks towards the camera in its new location.

There are zero reasons for him to be entering my bedroom and I am afraid of escalation. The way he acts on camera, it is hard to describe just how creepy and malicious it seems.

I don’t want to confront him about entering my room because I’m afraid he will just retaliate or attack me in another room. Him just not entering my bedroom anymore is not an adequate solution for me to feel safe. I want to get him out ASAP. I have a few questions I haven’t been able to answer by looking through the wiki/faq/google.

Is this enough evidence to begin eviction?

Is the motion activated camera legal in MD? MD is two party consent but Ring security cams seem to be legal. Is it legal to record my own bedroom?
