Summary：1. First, check that the power supply and network cable are functioning correctly. Verify whether the camera's indicator light is on and try pinging the camera's IP address.
2. Check whether the computer's IP address and the network camera's IP address are on the same network segment. An IP address consists of four sets of numbers separated by dots (e.g., 192.168.0.100 or 10.10.1.254); for most users, the address follows the 192.168.X.X format.
1. First, check the power supply and network cable connections. Verify that the camera's indicator light is on and try pinging the camera's IP address.
2. Check if the computer's IP address and the network camera's IP address are on the same network segment. An IP address consists of four sets of numbers separated by dots (e.g., 192.168.0.100 or 10.10.1.254). For most users, the address follows the format 192.168.X.X (where X ranges from 0 to 254); devices are on the same segment if the first three sets of numbers match. Within the same segment, every IP device (computer, network camera, or IP phone) must have a unique IP address to avoid conflicts. IP addresses can usually be changed manually on the device itself. If the computer and the network camera are on different segments, you must first change the computer's IP address to match the camera's segment.
3. Confirm the network camera's IP address. If you are unsure, use the search tool provided with the camera to locate it (for example, the default IP address for Tianshida cameras is 192.168.1.2).
4. Check if the camera's IP address is already in use by another device on the network. If so, connect the camera directly to your computer to change its IP address (or use the search tool to modify it), then reconnect it to the LAN switch.
5. Ensure that the necessary video software (ActiveX control) for the network camera is installed on the monitoring computer.
Note: Before installing the control, you must reset the Internet Explorer (IE) security settings to "Low" under "Custom level" (ensure ActiveX-related options are enabled). Then, enter the camera's IP address into IE; the system will prompt you to install the control—click "Yes." Once installed, enter the correct username and password (provided by the manufacturer) and click "Connect." Please note that most network cameras currently do not support server operating systems or Windows Vista.
