The opening of 20 prevents an unnecessary call signal from being sent to the telephone terminal 19.

Further, the video message sent from the video message sending device 3 to the recording control circuit 13 via the video line (not shown) via the control device 1 is generated when the AND logic of the AND circuit 12 is established. So that the video message is recorded in the memories ME _{1 to} ME ₈ of the memory unit MEU.

When the handset 19a of the telephone terminal 19 of another living room EQ ₂ is off-hook while recording in the living room EQ ₁ , the ringing signal sent from the telephone terminal 19 is normally closed from the terminal 9d of the living room EQ _2. Voice call signal switch 20, signal distributor 11a and terminal 9b
Although the call signal is not sent from the signal distributor 11a to the call signal detection circuit 11 though the terminal adapter 6b of the room adapter 6 is sent via the, the erroneous individual video message is not recorded in the room EQ ₂ . In addition, at this time, when the other entrance device EQ ₂ is called from the camera-equipped entrance entrance device 4, the video message recording device for the housing complex has only one communication path, so the video message from the manager room device 2 to the room device EQ ₁ is displayed. While recording, the other indoor unit EQ ₂ cannot be used while busy.

Further, in the case of a normal call, a call signal is sent to the telephone terminal 19 via the voice call signal switch 20 which is normally closed.

The video signal of the visitor captured by the camera eye 4a of the camera-equipped front door 4 is passed through the memory unit MEU from the recording control circuit 13 and directly displayed on the TV monitor 18 via the video signal transmission circuit 17. Alternatively, the recording is controlled to be recorded in the memories ME ₁ to ME ₈ of the memory unit MEU by the recording control of the recording control circuit 13 as needed.

Number of installed room unit EQ ₁ ~EQ ₈ is not limited to eight in the above example. The number of the memory ME ₁ ~ME ₈ in the above examples are not intended to be limited to 8 screen.

EFFECTS OF THE INVENTION According to the video message recording device for an apartment house of the present invention, an unnecessary call signal is sent to the telephone terminal provided in the room and the video message is erroneously recorded in another room. Abnormal operation can be prevented.
