Smart Home Security Alarm Linkage System Solution

Background of the project

With the continuous development of society, people’s living standards have been continuously improved, and people’s attention to family safety and property is also increasing. More and more families choose to install security monitoring equipment at home, such as: infrared detectors, humidity alarms, access control, smoke detection, monitoring and other alarm devices. However, these systems are often independent of each other and upload alarm information through the telephone line. Frequent occurrences of false positives, missed reports, etc. In many cases, even if an intrusion alarm occurred, it was because the linkage with the police was not timely, resulting in the criminal suspect fleeing and then fleeing. The consequences of handling the case were difficult.

The original alarm system function is briefly described

The original system consists of indoor infrared detectors, temperature and humidity detectors, access control, smoke sensor, and alarm host. The monitoring center consists of an alarm server. The original system provides different alarm services according to the type of front-end alarm device, including infrared detection, access control, smoke detection, etc. These data are uploaded to the alarm server via the telephone line through the alarm host.

The disadvantages of the original system

Because there is no effective control mechanism, false alarms cannot be handled, and false alarms often occur. The entire alarm wit is uploaded via the telephone line, and charging on time will generate high telephone charges. Cause user complaints. Without video management, users cannot view live video in home conditions. When the alarm occurs, the user cannot get the alarm prompt at the first time. (does not support mobile terminals). The security company does not have server-level effective management intelligence. It cannot locate the location of the alarm in time, and cannot query user information in time. Without an effective storage mechanism, alarm records cannot be queried.

New Network Video Alarm Monitoring System Design Requirements

For some drawbacks of the existing alarm system, the new system design will use the latest alarm control mechanism to provide users with real-time and reliable alarm services. The front end of the new system is mainly composed of alarm equipment and video monitoring equipment. The center of the system will consist mainly of platform servers and monitoring clients.

The project system provides the following functions

The system provides alarm device access platform services. The original alarm system seamlessly interfaces with the new system platform and can be accessed without modification.

The system provides real-time video viewing services.

The system needs to have the alarm linkage function, such as motion detection alarm, abnormal device disconnection alarm, linkage capture, linkage recording, and so on.

The system supports mobile handset services. Users can browse videos through mobile phones, receive SMS alarm messages, and remotely deploy, withdraw and prevent mobile phones.

By monitoring the client, when an alarm event occurs, the alarm location can be accurately and accurately provided to the staff member.

The system has a large amount of storage capacity, can effectively store 3-5 years of alarm data, and is easy to check. Utilize carrier-grade service platforms to effectively save communication costs in the alarm system.

The PC and mobile client are bound to the user's mobile phone and have a verification code function.

Project System Diagram



The entire project is based on the Internet. Users can install network video monitoring equipment at the entrance to the home or on the wall. The network video monitoring device can collect user videos and send the videos to servers located at the center through the network. Users can remotely log on to the central server by using a computer or mobile phone to check their own home security situation.

Front-end equipment can be connected to various brands of alarm host, the signal collected by the alarm host, through the network back to the central platform server. The central platform server can notify the security company and the user via SMS via a pre-configured linkage strategy, prompting the user whether to select an alert. At the same time, the front-end device can capture live images and send the pictures to the users in the form of MMS. The user can determine whether there is a need for an alert based on the returned images. The user can also use the mobile client to log on to the center platform to view the live images. Determine whether it is a valid alarm After the householder confirms the situation with his/her mobile phone, he or she can directly reply to the security company to inform whether he needs to touch the police. In this way, we will effectively use the alarm system to achieve the purpose of security prevention more quickly and accurately.

Security System Function Description

1. Front-end user home centralized management function: Due to the large number of front-end users, the platform database system will record the basic information of each user for management convenience. When the alarm is generated, it can query the family status in real time, and the owner's multiple contact methods. Can authorize video browsing or not.

2.3G network circuit real-time monitoring function: 3G network can be used as the transmission medium in the router to achieve the purpose of alarm online and image transmission.

3. SMS, MMS send, receive, forward function: alarm probe linkage camera capture pictures, send SMS, MMS enter the central server processing platform through the 3G network, the platform forwards to the user mobile phone, PC terminal. The user replies to the confirmation message sent by the platform to the security company to confirm whether it is an alarm. The entire SMS and MMS are forwarded to the operator's mobile phone via the central platform.

4.110 Alarm linkage function: The platform accepts the user to confirm the alarm message and forwards the security company to confirm the message and picture. The security service company can choose whether to link 110 according to the actual dangerous situation and achieve automatic alarm.

5. Compatibility with the original alarm platform: The platform can directly interface with the existing security company's built-in alarm system. All functions of the system can be realized without the need for line design modification.

6. Data center management functions: Central service storage management Front-end camera video streams, recording alarm audio streams, storing short message alerts, capturing picture information, logging log data of individual user alarms, and central database recording front-end multiple user data (user home information) , contact information, etc.)

7. Video service forwarding storage function: Users can use a mobile phone or PC machine to remotely monitor video in real-time, real-time attention to home conditions.

8. Log storage, query function: The platform has the ability to record alarm log management. There will be a log record for each piece of alarm information. At the same time, a detailed record will be made for each alarm's SMS response and alarm status so that the query can be made.

9. Multi-layer electronic map linkage management: The platform has the function of video alarm and map linkage. When the alarm is generated, the security company can accurately locate the home location where the alarm occurs according to the multi-layer electronic map function provided by the platform software. At the same time, inquire about the family's basic information
