Hi
Welcome to Microsoft community.
Unfortunately, you cannot directly connect a USB camera to a router using a USB to RJ45 adapter and expect it to work. The Microsoft Lifecam HD-3000 is a USB camera designed to be connected directly to a computer, where it requires drivers and software to operate.
Here are a few possible solutions:
- USB over IP: There are solutions like "USB over IP" which allow USB devices to be shared over a network. This involves connecting the camera to a computer, then using software to share the camera over the network. Note that this will require the computer to be on whenever you want to use the camera.
- Network Camera Adapter: There are also devices known as "network camera adapters" which can turn a USB camera into a network camera. These devices can be quite expensive and may not work with all cameras.
- Wireless USB Extender: Another option could be a wireless USB extender. This would allow you to place your camera at a distance from your computer, with the camera connected to the USB transmitter and the receiver connected to your computer.
- IP Camera: If you require a camera to work over your network, the best solution might be to purchase an IP camera. These cameras are designed to work over a network and can be easily connected to your router and accessed from any device on your network.
