One Of My Roommates Has A Camera In Our House That My Sister And I Are Uncomfortable With. Is That Legal?

My dad's ex fiance put up a camera in the house to "make sure no one breaks into the house and if they do, we can see their face." This makes my sister (who I'll call M) and I uncomfortable.

Now, we live in PA, and D (my dad's ex fiance), decided to set up the camera in the dining room when my dad passed away almost 2 years ago. My sister and I hate the camera because it makes us uncomfortable.

The camera can see all of the dining room, into the kitchen where the back door is, and most of the living room. M and I have a different sleep and work schedule than D, which means that we are awake when she's asleep. This means that D can see everything that happens when she's not awake.

M and I never gave our consent to being on camera and have told D that we are uncomfortable with it and that it's an invasion of privacy. All D said was that "well, you guys don't have to worry about your stuff getting stolen." I don't know what she's on about because we have pretty expensive stuff in our shared bedroom. And the stuff we are allowed to keep downstairs.

D states that she never actually watches the cameras but M and I know that it's a lie as she gets the videos sent straight to her phone anytime there's movement where the camera can see (which is basically all of the downstairs). We know it's a lie that she never watches them because D has a dog and when she's gone for a couple of days she will use the chirping feature on the camera to get the dogs attention and talk to her.

We have no clue if this camera records audio, seeing as you can talk to the person watching the camera and D speaks through the camera to the dog.

My dad was the one who owned the house last, and the house will go to me once I can get the money to have it put in my name. I just don't want this camera watching my every move and neither does M.

We both grew up in not so great households where privacy was taken away from us and this camera is not helping at all. I honestly just don't know what to do about it.

I uploaded this post about a year or so ago and it has gotten worse.

The old camera stopped working, and now there's a new one that records audio. I don't feel safe in my own home, and I honestly don't even want to be downstairs at all, knowing that she can hear everything that is being said. I don't know what to do because if I move it or do anything to it to make myself feel safe, she'll get mad and yell at either me or M about how she doesn't feel safe. I'm trying to get the house into my name, but in the meantime, I don't know what to do.
