An energy conserving remote power efficient viewing system comprising an
instantaneous analog video transmission camera, an analog video receiver
that receives and transmits a video image to a video monitor and a remote
transmitter that activates the analog video transmission camera. The
remote camera device is normally off, sleep mode that has a minimal power
drain. The system includes a battery powered camera requiring a first
voltage to operate and an RF transmitter to send an activation signal to
the camera. The activation signal has a duration. A camera power circuit
includes a normally sleeping signal receiving circuit and a first timer.
The first timer periodically activates the signal receiving circuit to
check for the presence of the activation signal and turns off the signal
receiving circuit if the activation signal is not present and turns on
the camera if the activation signal is present, and wherein the time the
signal receiving circuit is off is less than the activation signal
duration.
