Title:
MONITORING DEVICE
Document Type and Number:
Japanese Patent JP3257103
Kind Code:
B
Abstract:
PURPOSE: To enable the recording of a video of a necessary route when monitoring is required.
CONSTITUTION: A command device 4 radiates a photograph start signal obtd. By subjecting a carrier wave of a prescribed frequency to pulse modulation by a prescribed code data a radio wave in the space from a transmission circuit. A main body device 10 is composed of a reception circuit 11, a demodulation circuit 12, a CPU 13, a timer 14, a driving circuit 15, a motor 17, a television camera 18, a ROM 29 and a video recording device 20. When the code data outputted from the demodulation circuit 12 is monitored and the code data is received, whether the reception signal is the photograph start signal or not is decided. The driving circuit 15, the television camera 18 and the video recording device 20 are started. The motor 17 rotates forward and backward by the driving circuitw 15 and the television camera 18 performs the oscillating motion by a prescribed angle. For this period, the video signal obtained by performing an image pickup by the television camera 18 is recorded in the video recording device 20.
