Given that the woman is not involved is there a legal ground for filing criminal charges against me just from the videos.
If someone is threatening you with legal action I suggest you use your RIGHT to remain silent.
You should also prepare to use some of your money to hire yourself a lawyer, if this does become a legal issue for you.
If someone thinks or believes you're pervert or a freak, there is NOTHING you can say (or should say) to disabuse them of that notion.
You can only further find yourself ensnared in a trap if you respond in anyway, shape, form, or manner.
I suspect the alleged images were stored on your employer's laptop, which is how you were outed.
A company issue device should hold company related information only.
If you MUST capture crude, pornographic images do that on YOUR property, not the property belonging to others which was issued to you for COMPANY business.
Good luck and get help as to why you enjoy taking surreptitious images of without the knowledge and/or permission of people who trust (once trusted) you.
This story and how it developed reminds me of the story of Huma Abedin and Anthony Weiner
