When installing a home security surveillance system, attention should be paid to network security. Since the home security surveillance system is connected to the Internet, there have always been security risks, but many manufacturers turned a blind eye or did not comply. technical requirements Network firewalls The application of video encryption technology is not easy, and the application of the encryption algorithm is too simple, which endangers the privacy of home users. With the development of remote home video surveillance technology and the popularization of applications, the relevant departments also realize the seriousness of network security. The upcoming national smart home standard will mention the problem of remote login encryption to prevent network intrusion in the future. The information system can indeed provide "blocking when soldiers come and coverage when water and land come" so that users can use remote home video surveillance with confidence.

The home security monitoring system is a kind of home technology protection. It uses network technology to connect video, audio, alarm and other monitoring systems installed in the home, and stores and sends useful information to other data terminals through processing. central control computer, such as mobile phones, laptops, 110 alarm centers, LCD screens, monitors, etc.

The process of creating a home security monitoring system:

Step 1. Determine the video transmission channel

Since surveillance images can only be viewed remotely via network transmission, the surveillance system must be able to connect to the Internet reliably. In order for users to be able to access the home video surveillance system normally, they must first face the difficulty of how to read the video surveillance system data from a remote device via a wireless network. Generally speaking, there are two methods that can be used to monitor a server's network. One is a direct dial-up connection from the monitoring server computer to access the Internet. This network method is relatively simple, if the monitoring server is successful, then a dial-up connection to access the Internet, and then run dynamic domain name analysis. software and video surveillance software. The other method is basically to perform a port mapping on the computers that use the router to access the Internet. If you want to access from the external network, you must assign the external network IP address to the internal network. Therefore, you need to apply for a dynamic domain name resolution service.

Step 2. Selecting monitoring equipment

After configuring the network settings, you need to build a security monitoring system. Preds monitoring systemIt is a typical home computer equipped with a camera and connected to the Internet. Since the camera device needs 24/7 continuous monitoring, the quality requirements of the computer are very high, and the power consumption is also low in terms of energy saving.

Step 3. Set up an external monitoring channel

The user wants to view the data in the video surveillance system remotely via a wireless network, that is, the monitoring image. What needs to be done is to transmit the captured video and audio through the network.
