The ciewia USB-A 2.0 Female to RJ45 Male Adapter is a passive physical connector that converts a USB-A 2.0 female port to an RJ45 male plug. Designed for specific professional applications including ADSL modem-to-router connections and professional surveillance camera setups. Lightweight and portable.

⚠️ Important: This is NOT a USB network card or USB Ethernet adapter. It will NOT provide internet access when plugged into a computer. It does NOT work with USB 1.1 (printer-style USB). A PoE data switch is required for network data transmission use cases.

• 【ADSL Modem to Router Connection】 Connect a USB ADSL modem to a router with an RJ45 socket via this adapter. The RJ45 male end plugs into the router's RJ45 port; the USB-A female end connects to the modem's USB cable. Note: The modem must have its own separate power source, as this adapter does not supply power from the router.
• 【Professional Surveillance Camera Setup】 Professional surveillance cameras connect to a LAN via Ethernet (RJ45). This adapter allows a standard USB camera to be connected alongside a professional surveillance camera on the same network segment, enabling simultaneous operation of both cameras through the RJ45-USB interface.
• 【USB-A 2.0 Female to RJ45 Male】 One end is a USB-A 2.0 female port (standard USB socket); the other end is an RJ45 male plug (8P8C). Passive physical adapter — no drivers or software required for supported use cases.
• 【Lightweight & Portable】 Compact design, easy to carry. Suitable for field use, home networking, and professional AV/surveillance setups.
