Video-audio access control intercom system and method

Abstract

The invention provides a video-audio access control intercom system and method, wherein a video-audio communication module receives an online request sent by a outdoor set to establish a linkage at two terminals, and transmits images acquired by the outdoor set to a preview module to store, and a video-audio communication module notifies a resonance module to send a resonance command to a dialogue starting agreement device to bell, and transmits the images to all dialogue starting agreement devices for preview when a user receives a call. after an module receives communication instructions sent by the dialogue starting agreement devices used by the user, the resonance module is notified no longer to bell responding to other devices, and generates an image communication between the dialogue starting agreement devices used by the user and the outdoor set; otherwise, a message leaving module is notified to enter a massage leaving mode. The access control intercom system can integrate image preview, communication device resonance and guest message leaving feedback, in order to ensure user privacy and have convenience.

Description

technical field [0001] The invention relates to an audio-visual access control intercom technology, in particular to an audio-visual access control intercom system and its method that can provide access control image preview, multi-device resonance and visitor message functions. Background technique [0002] With the prosperity of the Internet, traditional analog voice telecommunications are gradually replaced by network-transmitted Internet telephony (such as VoIP) technology, and Internet telephony devices supporting session initiation protocol (SIP) are also widely used in smart homes Among them, for example, access control intercoms and telephones can use SIP video phones, or computers can form video phone devices through SIP software, so it can provide communication needs for smart homes indoors and outdoors. [0003] At present, most smart houses use audio-visual walkie-talkies as access control. The devices such as door phones, touch computers, video phones, etc. all ...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, it is a schematic diagram illustrating the operation of an existing access control intercom system using a SIP device. When a visitor presses the doorbell through the intercom 10, a SIP call (SIP call) will be sent to the network switch 100, and the network switch 100 performs resonance After the function, send a SIP call to the numbers of devices such as the touch computer 11 and the video phone 12, so that the touch computer 11 and the video phone 12 are both in a ringing state, and an image is established after any device in the two devices is connected. Talk and stop other devices ringing at the same time. This is a common access control intercom system using SIP devices. Although it is convenient, there are still many problems. For example: when visitors hear the ringing stops, it means that the residents are at home (the SIP device has been touched), And usually when the resident connects to the phone, the SIP device will immediately send the sound or image, which causes the privacy of the resident to be violated

To improve the above problems, it may be necessary to customize SIP devices such as door phones, touch computers, or video phones. However, this will increase the cost. In addition, SIP devices lack the image preview function, and they cannot see the other party’s image in advance before making a decision. Whether to talk, which causes inconvenience and trouble in use
