Cameras Located Within Agency and Provider Incall Spaces

[Silverfox]

So essentially,
If the agency or provider does not give prior warning to the client and does not obtain explicit consent for filming with cameras inside the incall were nudity and sexual activity is occurring, it is considered illegal.

Currently, the way these agencies and providers are using their cameras inside their incall locations violates several serious laws. 
Is there any way they could continue this practice lawfully? 
Are there any methods they can adopt to alter their practices and make them lawful?

Im. no laywer, but what from what I gather reading the relevant laws, they would need to:

-Inform the client ahead of their appointment about the presence and location of the cameras. This would be done through their advertisement or by sending a text message stating this during the booking process.

-Upon arrival at the incall, the provider who is present must inform the client about the camera's presence and identify its location. The provider should then request the client's explicit consent for the camera to be present and active during any nudity or sexual activity. The client must agree by confirming with a "Yes, I am aware and okay with it."

Even in the above is met, it would be particularly challenging for agencies, as the agency owner is likely the one who owns the camera and has access to its footage. 
Therefore, they would be the ones held liable if any of the above procedures are not followed precisely.

It will be interesting to see whether any providers or agencies with these cameras adjust their practices now that they are aware of the applicable laws. If they choose not to, they are knowingly violating multiple laws and could face significant legal consequences.
