ABSTRACT
Now a day modern developments in monitoring devices is been big boon to the society, but the
improper utilization of those technology will create sophisticated environment like hidden
camera. These cameras are being hidden by the structures or by any decoration items in the
room, which is used to record the actions without the knowledge of people. Hidden cameras can
be built into commonly used objects such as television sets, smoke detectors, clock radios,
motion detectors, ball caps, plants, and mobile phones. The use of hidden cameras raises
personal privacy issues and there may be legal aspects to consider, depending on the jurisdiction
in which use takes place. There is no efficient way to detect the spy camera now a day. Hence we
are going to develop a new project which concentrates on this scenario.

In this project we use RF signals for the

we should use the calling option to increase
the RF signals.
