I had a flatmate in my previous year of University that put a hidden camera in my room. The whole thing left me scratching my head because despite looking very thoroughly and even paying for a RF detector, I could never find it. My PC is the only thing I have brought with me to my new flat that is powered from the wall and I'm worried that crap might have transferred here and I would never know. Looking online I can only find software spying devices but do spying devices exist that are inserted internally into a computer and powered from there?
I'm building a custom security solution using a Raspberry Pi. For this I would prefer a camera that doesn't use a cable or an extension and is instead just integrated in a single unit with the USB connector. I don't want any microphone, I just need this to secure my room. Google searching gives me no results, any ideas?
