How do I CAUSE interference on a camera please....on the audio part. Any ideas?

Anything that would be effective in the way you want it to be would also interfere with your phone calls.

You people have no understanding. I do have friends who are international and just cannot fit into my 2 hours off in 24 hours or businesses that only operate outside my 2 hours off and cannot leave the house to take or make a call. Mamianka...keep your judgements to yourself about this you certainly have no idea what this is like having no privacy whatsoever! I asked a question not your short sighted answer. Thanx spacemissing for a decent answer

Maybe that is why they have cameras installed. Use your breaks to go outside and make your calls like everyone else does.

Great job asking this IN PUBLIC - because your employer should just FIRE YOU on the spot. You are disabling private security equipment, designed to protect the person for whom you care - and also YOU, if you were ever accused of doing something that you did NOT do. If you work 24/7, you should have SOME respite time - and that is when those private conversations should take place. Or TEXT - but you are being paid to WORK, not run your social life.
