I recently went to see a reputable lady with about 2 pages of good reviews. I had a good time, and before I left, I remember thinking I'd like to see her again.  The apartment is kind of a studio, with a small bedroom or alcove bedroom.  When you walk in, the kitchen is two feet in.
When we were saying our goodbyes, basically in the pass through of the kitchen, I saw something move out of corner of my eye. We're talking, I take a step back towards the door, and again I see something move.  This time I turned my head toward the kitchen to see what it was, and there is a mounted camera in a 3"x5" white rectangle, facing us.  When my head turned, it moved again.  She asked if I was freaked out and I said YES.  She then said "it's just for my safety, and it doesn't record".  I don't think I responded, but I was thinking, if it doesn't record, how does it help her safety?  I was pretty stunned, and walked out the door.
That got me thinking about if there were other cameras in the room, and how often they are in other apartments.  It really has me re-thinking ever doing an incall again.

I'm fairly new to this, and my first time I was concerned about cams, so I booked a room and scheduled an outcall.

I always assume that any woman who uses her residence as an incall might have cameras around.  

I’m not buying it doesn’t record. A camera that doesn’t is a fake camera or a toy. Like you said, what’s the point? What does a dummy camera do for her safety? Now I might buy that she doesn’t keep the recording, and perhaps that’s what she meant. If she’s a legit provider, she likely wouldn’t want to risk losing her clients by doing anything with said recordings. But yeah, I wouldn’t feel great about it.

I do not entertain at my private residence. I utilize Wyze to monitor my home it records. I would assume most people have cameras. Ring cam is very popular. Anytime a crime happens the first thing people look for is cameras. Who had one and who's recording?

I don’t do in-calls unless I’ve meet the provider before. They want all kinds of information from you but don’t want to reveal anything about themselves. You need to protect yourself.

I’m not familiar with Wyze, but most people use Ring to monitor outside. An outside security camera is very common. I wouldn’t have any concerns about one. What the OP described sounded like an inside the house camera. That’s a little more concerning.

If she’s a legit and reviewed provider like you said, you have nothing to worry about. It’s a safety measure - you’re on camera every time you leave the house whether you know it or not. She’s not risking her reputation or brand by leaking a video of you walking in the living room.. can’t say if she’s telling the truth if it worked, only she knows. Highly doubt she’s a weirdo that has a camera where the action takes place though.  

Then why not be forthright and say to a potential client when they book? Hey I’m filming for my protection. You know damn right her business would drop. It’s deceitful and a bunch of shit.

If a prostitute is recording her tricks and gets busted, seems to me an open and shut case for LEO against HER.  Also, how does the recording of the session protect anyone?  So she can go to the police and explain how her trick robbed and beat her?  I suppose, but isn't she running the risk of being charged with prostitution?  BTW, your camera is either being recorded or Bruno is watching in the next room.  

Maybe wear a mask to and from the bedroom?  I don't tend to see providers who work out of their residence, but I'll remember this post if I do.

If she were to subtly draw attention to its presence at the start (and not volunteer that 'it doesn't record'), it could be a deterrent.

I can understand your point without cursing. I acknowledged OP’s feelings in my original comment.  

damn right she could (and should) go to the cops - and bring the film. They would have zero interest in her business and a lot in her abusive client.

in that situation. How I'd react would depend upon the person, our rapport and the circumstances. Trust and Safety are two sides of the same road - and the road goes both ways.
