In FIG. 1, reference numeral 1 denotes a camera-equipped front door subunit 1a in which a camera 1b is built in, and n units can be connected. Reference numeral 3 is a monitor television unit having a built-in monitor television for displaying an image captured by the camera 1b, and reference numeral 2 is a front door subunit switching device with a camera for switching the connection between the front door subunit 1 with a camera and the monitor television unit 3.

The camera-equipped front cordless handset 1 has a call button 4, and the monitor television unit 3 has an external monitor television unit 16. Entrance device switching device 2 with camera
Is a display panel 12, a CPU 5 for controlling each block,
An incoming signal detection unit 6 that detects an incoming signal from the camera-equipped slave unit 1, an incoming-signal transmission unit 7 that sends the incoming signal to the monitor TV unit 3, and the camera-equipped slave unit 1 and the monitor TV unit 3 are connected. Relay control section 9 for controlling the relay 9a, a ring counter 11 for sending a signal to the relay control section 9 at regular intervals, an LED control section 8 for controlling the lighting of an LED 13, which will be described later, and a camera-equipped front subunit selection section 10. Is equipped with. The display panel 12 includes an LED 13, a camera-equipped entrance cordless handset selection button 14, and a continuous monitor button 15.

The operation of the above configuration will be described below. When the visitor presses the call button 4 of the camera-equipped front cordless handset 1, an incoming signal is transmitted from the camera-equipped front cordless handset 1. The incoming signal is detected by the incoming signal detection unit 6 in the camera-equipped front cordless handset switching device 2, and which of the camera-equipped front cordless handset 1 has called is transmitted from the incoming signal detection unit 6 to the CPU 5. The CPU 5 controls the incoming signal sending section 7 to send the incoming signal to the monitor television unit 3.
