In order to check that your IP camera is connected to the network and has a valid IP address, you should access the IP camera's web interface or app with a computer or smartphone. If you can view the live video feed, then the network connection is fine. If not, you'll need to check the network cable or wireless connection, making sure it is plugged in securely and there are no breaks in the wire. If your IP camera uses Wi-Fi, you may need to adjust the antenna or relocate the camera or router to improve the connection. Additionally, you should check that your IP camera has a valid IP address, subnet mask, gateway, and DNS server. You can usually find these settings in the IP camera's web interface or app, or use a network scanner tool to scan the network and find the IP address. You may also need to configure your firewall to allow the IP camera's IP address and ports, or disable it temporarily for testing purposes. Furthermore, ensure that your router has port forwarding enabled and it is forwarding the IP camera's ports to its IP address. This will allow you access to the IP camera from outside the network.
