Absolutely it's a risk and one of the dodgy punters on warnings board, I actually saw in hindsight his computer was whirring away and in full operation mode. I never really thought about it til then. 
Outcalls you can't really control it as much, as you are probably going to be in various different rooms, so i guess you might even consider not offering home visits on this basis. Personally I will do them but only because I'm going on the basis I will be clothed in areas other than when the action is going on and in that room, I scan as best as I can / look for laptops/ open wardrobe etc
on hotel visits ask that laptop lids are down (I make light of it with a 'we don't want anyone spying on you do we:)' 
look out for any strangely placed coats/bags etc
If they have their own alarm clock move this to face the other way (you can get spy clocks)
I am also careful of them fidding on their phone like sending sms etc during the meeting, recently I caught one trying to get a covert photo
I also don't visit offices as they are full of CCTV
If the worst happens and they do record a session, then I would guess the quality is not going to be great ?
I try not to think about it in overdrive otherwise the paranoia would be too much but I do think about it now on each and every booking, even trusted regulars

I'm going to be watching out for it, I think it's a risk to anyone, anywhere in any situation sex work or not.

Just watch out for phones, and gadgets.

I think I once had my voice recorded during incall so I don't think anyone is safe.

In my opinion, it's not so easy to fool an attentive eye !!
Anyway , there are gadgets sold online which are completely undetectable .
I do remember here that publishing unauthorised material is a criminal offence , hence I rest quietly thinking that eventual recordings will be kept private 

I've been victim of crimes which would have been solved if CCTV had been in place as it should have been. So I don't mind CCTV, so long as it isn't misused. Before these incidents I too disliked it immensely.

Hi Mirror, your right about the CCTV of course and I wasn't suggesting it isn't a good thing It's all the secret miniaturized recording I don't like and how everybody now records and uploads whatever foopah someone makes or meltdown and uploads it to youtube. I hope they caught whoever perpetrated the crime against you xx

Camera are so tiny now, you can get them in anything from smoke alarms to pens and buttons.

Take a look at this!

I don't do outcalls anymore and any of their belongings need to be placed under their clothes
