Open broadband at home, and connect the camera with network cable and power cord. You don't need to make any settings. After installing the APP client on the mobile phone, enter the ID number of the camera, and you can monitor it with the mobile phone.

Spend five or six hundred dollars to buy a cloud-connected network camera supported by a cloud server. Because the manufacturer provides a cloud platform that supports the point-to-point connection between the client and the camera, it is very simple to install and use, and you can do it yourself without the support of professionals.

As long as there is broadband access at home, connect the camera to the internet cable and power cord without making any settings. Install the APP client on the mobile phone, enter the ID number of the camera, and you can monitor it with the mobile phone. The same is true of computers. Start the client program, enter the ID number of the camera, and you can watch it.
