Heat signature of security camera

  1. May 10, 2012 #1
    Is it possible to use a thermal imaging camera to detect the heat signatures of a security camera? Are you familiar with any equipment which can detect its electrical, electromagnetic or metalic signatures?

    You might wonder why I'm asking. It's because I'm a bachelor degree student in mechatronical engineering focusing on feedback control systems and frequency modulation.

    This is TEMPEST technology. Most of it would be classified. The basic principle is to construct a neural network to classify detected radio emissions. You would need examples to train the classifier to relate emissions to a type of device. Its not just limited to Security cameras, keyboards, monitors and generally any electronic appliance are fair game. With proper receivers, well trained classifiers, you could point your equipment at any building and build a list of all the electronic items within.
