A two-line video intercom method supporting multiple cameras and multiple indoor units, comprising the following steps: Step 1: installation; Step 2: video surveillance; Step 3: visitor docking; Step 4: self-unlocking; The features are: In the above step 1, firstly, the outdoor machine (4) is installed outside the door, the required number of cameras (3) are installed at the required positions, the required number of door machines (1) are installed in the required rooms indoors, the switch (2) is installed, the outdoor machine (4) and the cameras (3) are connected to the switch (2) through a two-wire non-polarity connection, and then the switch (2) is connected to the door machine (1) through a two-wire non-polarity connection, and the required modules are installed in the installed equipment, and the corresponding parameters are set for debugging; In the above step 2, the image of the housing area is collected in real time by the image acquisition module (311), and the image is classified by the classification module (313), and then transmitted to the image output module (312), and the image is transmitted to the camera receiving module (213) by the image output module (312), and the image is received by the camera receiving module (213), and the image is transmitted to the camera transmission module (214) after processing, and the image is transmitted to the central processing module (111) by the camera transmission module (214) for processing, and then transmitted to the monitoring module (115) by the central processing module (111), and the user views the screen of the housing area through the monitoring module (115); In the above step 3, the call signal is transmitted to the signal receiving module (211) through the call module (419), and the call signal is transmitted to the signal transmission module (212) through the signal receiving module (211), and the call signal is transmitted to the central processing module (111) through the signal transmission module (212), and the call signal is transmitted to the reminder module (116) through the central processing module (111), and the reminder module (116) reminds the user that someone is visiting, and the sound signal is transmitted to the signal receiving module (419) through the sound transmission module (418). The signal receiving module (211) transmits the sound signal to the signal transmission module (212) through the signal receiving module (211), transmits the sound signal to the central processing module (111) through the signal transmission module (212), transmits the sound signal to the answering module (118) through the central processing module (111), transmits the sound to the user through the answering module (118), receives the user's voice through the call module (117) and transmits it to the signal receiving module (211), and transmits the sound to the user through the signal receiving module (211). The signal transmission module (212) transmits the signal to the sound receiving module (420) through the signal transmission module (212), and the sound receiving module (420) plays the user's voice to the visitor; the face recognition module (413) captures the image in front of the door machine (4), and then transmits it to the face transmission module (414), and the face transmission module (414) transmits the image to the image receiving module (215), and the image is received and processed by the image receiving module (215), and then transmitted to In the image transmission module (216), the image is transmitted to the central processing module (111) for processing, and then transmitted to the monitoring module (115) through the central processing module (111), and the user views the door screen through the monitoring module (115); the door machine (1) is connected step by step according to the installation position through the connection ringing module (119), and when the door machine (1) of the upper level does not respond, the door machine (1) of the lower level is reminded to ring through the connection ringing module (119); In step 4, the environment in front of the door machine (4) is sensed by the light sensing module (411). When a person approaches, a signal is transmitted to the LED module (412). The LED module (412) controls the LED screen to light up and provide auxiliary lighting. An ID card is placed on the door machine (4), the ID card is sensed by the identity sensing module (415), and is identified by the identity recognition module (416). When the unlocking requirements are met, the door is unlocked by the unlocking module (417).
