AI Technical Summary

Technical Problem

Users cannot monitor network cameras from different brands using a single mobile app, especially those in public areas. They also need to install apps from multiple manufacturers to achieve monitoring, resulting in a poor user experience.

Method used

The system uses an indoor unit to locate network cameras on the same network, registers them with a SIP server, allows a mobile app to query the camera list, switches between surveillance cameras using DTMF commands, and forwards video to the mobile app using the RTSP protocol, enabling video monitoring across different camera brands.

Benefits of technology

It enables video monitoring of network cameras across brands, solves the problem of poor user experience, allows monitoring of multiple cameras, including public area cameras, through a single APP, and simplifies the operation process.

Abstract

This invention belongs to the field of building intercom systems, specifically a method for an indoor unit to forward network camera video to a mobile app. The method includes the following steps: S1: The indoor unit locates a network camera on the same network as the indoor unit and adds it to the indoor unit's network camera list; S2: The indoor unit registers with the SIP server using account sip1; S3: The mobile app also registers with the SIP server using account sip2. This invention uses the indoor unit's RTSP to retrieve network camera data and forward it to the mobile app. It can monitor both the indoor unit and the network camera, and allows for real-time switching, effectively solving the problem that residents' mobile apps cannot monitor network cameras in public areas of the community, and also resolving the issue of residents needing to install different manufacturers' apps when using different brands of network cameras.

Description

Technical Field

[0001] This invention relates to the field of building intercom technology, and in particular to a method for an indoor unit to forward network camera video to a mobile APP. Background Technology

[0002] It turns out that if people want to monitor their home network cameras through a mobile app, they can only do so through the network camera manufacturer's mobile app, and they can only monitor their own private cameras; cameras in public areas cannot be monitored. If the network cameras are not from the same manufacturer, different manufacturers' apps need to be installed, and each app can only monitor the corresponding network camera, which is not user-friendly. Based on this, we propose a method for indoor units to forward network camera videos to mobile apps. Summary of the Invention

[0003] This invention proposes a method for an indoor unit to forward network camera video to a mobile app, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A method for an indoor unit to forward network camera video to a mobile app includes the following steps: S1: The indoor unit finds network cameras on the same network as the indoor unit and adds the network cameras to the network camera list of the indoor unit; S2: The indoor extension unit registers with the SIP server using account sip1; S3: The mobile app also registers with the SIP server through account sip2; S4: The mobile app actively queries the list of network cameras on the indoor unit, and the indoor unit reports the list of network cameras to the mobile app. S5: The mobile APP calls the indoor extension through the SIP server. The indoor extension receives the call from the mobile APP and answers it. The indoor extension sends the video from its camera to the mobile APP, and the mobile APP can then view the video on the indoor extension. S6: When the mobile app switches to the network camera you want to view, the mobile app will send the corresponding DTMF command to the indoor unit. After receiving the corresponding DTMF command, the indoor unit will find the RTSP URL of the corresponding network camera based on the DTMF command. S7: The indoor unit monitors the network camera via RTSP. After receiving the video data, the indoor unit sends the data from the local camera to the mobile app instead of the local camera data.

[0005] Preferably, in step S1, the indoor unit uses the ONVIF protocol to locate network cameras on the same network as the indoor unit.

[0006] Preferably, in step S3, the mobile app is pre-installed on the mobile phone.

[0007] Preferably, in step S4, the mobile app actively queries the list of network cameras on the indoor unit via SIP message.

[0008] Preferably, in step S7, the mobile app can view the network camera added to the indoor unit.

[0009] Compared with existing technologies, this invention retrieves network camera data via an indoor RTSP unit and forwards it to a mobile app. It can monitor both the indoor unit and the network camera and switch between them at any time, thus effectively solving the problem that residents' mobile apps cannot monitor network cameras in public areas of the community. It also solves the problem that residents need to install different manufacturers' apps when using different brands of network cameras. Detailed Implementation

[0010] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0011] A method for an indoor unit to forward network camera video to a mobile app includes the following steps: S1: The indoor unit uses the ONVIF protocol to find network cameras on the same network as the indoor unit and adds the network cameras to the network camera list of the indoor unit; S2: The indoor extension unit registers with the SIP server using account sip1; S3: The mobile app is pre-installed on the phone and is also registered to the SIP server through account sip2; S4: The mobile app actively queries the list of network cameras on the indoor unit via SIP message, and the indoor unit reports the list of network cameras to the mobile app. S5: The mobile APP calls the indoor extension through the SIP server. The indoor extension receives the call from the mobile APP and answers it. The indoor extension sends the video from its camera to the mobile APP, and the mobile APP can then view the video on the indoor extension. S6: When the mobile app switches to the network camera you want to view, the mobile app will send the corresponding DTMF command to the indoor unit. After receiving the corresponding DTMF command, the indoor unit will find the RTSP URL of the corresponding network camera based on the DTMF command. S7: The indoor unit monitors network cameras via RTSP. After receiving video data, the indoor unit sends the data from the local camera to the mobile app, allowing the mobile app to view the network cameras added to the indoor unit. This embodiment uses an indoor unit's RTSP to retrieve data from the network camera and then forwards it to a mobile app. It can monitor both the indoor unit and the network camera and switch between them at any time, thus effectively solving the problem that residents' mobile apps cannot monitor network cameras in public areas of the community. It also solves the problem that residents need to install different manufacturers' apps when using different brands of network cameras.

[0012] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
