Modern IP cameras can often generate multiple independent video streams, each with distinct parameters. Some models support up to five streams, though most commonly ship with three. A typical configuration might be: Primary Stream — Recorded at the camera’s maximum resolution for archiving or detailed review. Secondary Stream — Lower-resolution output (often no more than 704×576) for display in a multi-camera (split-screen) view on a monitor. Tertiary Stream — Stream for mobile access when remote viewing on smartphones or tablets is required. Key adjustable parameters for each stream usually include: Image Resolution Frame Rate Codec (e.g., H.264, H.265) Compression or Quality Settings Connecting an IP Camera to a Computer To expedite installation at the job site, it is best to preconfigure IP cameras in an office or lab environment. A straightforward method is to connect each camera to a laptop or desktop computer via a standard Ethernet patch cable (Category 5e or better) terminated with RJ-45 plugs. Physical Connection: Connect the camera’s network port directly to your PC’s network interface using a patch cord. Provide power to the camera. If you have Power over Ethernet (PoE), you can use a PoE injector or PoE switch. Otherwise, use a dedicated 12 VDC (or 24 VAC, depending on specs) power supply. Network Settings on a Windows PC: On Windows 7, 8, 10, or 11, locate the Network icon on the taskbar. Right-click and select “Open Network & Internet Settings” (wording may vary slightly by OS). Click “Change adapter options” or “Change adapter settings.” Right-click the relevant Local Area Connection (Ethernet) and choose “Status”, then “Properties.” Highlight “Internet Protocol Version 4 (TCP/IPv4)” and click “Properties.” Assigning IP Addresses Manually: Change from “Obtain an IP address automatically” to “Use the following IP address.” In “IP address,” enter a number in the same subnet as your camera (for example, 192.168.1.100), but ensure it does not conflict with the camera’s own IP address or the gateway. In “Subnet mask,” use the value required by the camera (commonly 255.255.255.0). In “Default gateway,” if needed, you can temporarily enter the camera’s default IP or leave it blank if you are working on a simple direct connection. Click OK to save.
