特徴とする家庭用監視装置。[Scope of Claim for Utility Model Registration] (1) In a home monitoring device that uses an indoor television receiver to receive video signals from a surveillance television camera installed at a location to be monitored, the ring tone from an outdoor intercom is transmitted. A sound sensing means arranged to collect sound, and an identification means for identifying whether the sound detected by the sound sensing means is the ring tone, and a signal from the television camera is detected by a signal from the identification means. A home monitoring device characterized in that a video signal is switched to a preset channel and displayed on the television receiver. (2) In paragraph 1 of the claims for utility model registration,
A home monitoring device characterized in that the acoustic sensor includes at least two filter circuits for identifying the ringing tone, and a circuit that outputs an output when both outputs from the two filter circuits are output. (3) In paragraph 2 of the claims for utility model registration,
A home monitoring device characterized in that a delay circuit is provided between one output side of the filter circuit and the output circuit for outputting the signal of the one filter circuit with a delay of a predetermined time.
