Product overview A compact PoE splitter and injector cable adapter that converts 48V delivered over Ethernet to 12V DC power for security cameras. It carries Ethernet data while extracting a 12V power feed so a single network cable can provide both network and camera power without running a separate power line. Key benefits Simplifies installation: Delivers 12V power and network data over one cable, eliminating the need for a separate power supply at the camera location. Flexible deployment: Lets you place cameras where power outlets are not available by using existing PoE switches, injectors, or midspan devices that supply 48V. Space saving and tidy: Compact inline adapter fits behind cameras or inside junction boxes to reduce cable clutter. Reliable performance: Designed to maintain stable 12V output while preserving network data integrity over Ethernet cabling. What it does Converts 48V PoE to 12V DC for devices that require a 12V input. Passes Ethernet data through while extracting power, enabling simultaneous network and power delivery on one Cat5/Cat6 cable. Works as a simple plugandplay adapter without configuration. Compatibility and use Compatible with PoE networks that supply 48V on Ethernet and with cameras or devices that accept a 12V DC input. Works with PoE switches, PoE injectors, and other 48V PoE power sources to provide a 12V output to cameras. Verify your camera's DC plug size and polarity before installation to ensure a proper physical connection. Key attributes Function: 48V to 12V power conversion and Ethernet data passthrough. Connectors: Standard RJ45 Ethernet interface on the PoE side and a 12V DC power output for the camera. Size and form: Compact inline adapter and short cable for discreet placement near the camera. Material: Durable plastic housing with flexible insulated cable designed for installation use. Performance: Stable DC conversion optimized for low voltage drop and uninterrupted data transmission. Practical applications Outdoor surveillance: Power a 12V outdoor camera from a central PoE switch located indoors, avoiding the need for outdoor power outlets. Remote locations: Install cameras above garage doors, in attics, or along fences where local AC power is not available. System upgrades: Add or relocate cameras on an existing Ethernet network without running power wiring. What to check before buying Confirm your PoE source provides 48V over Ethernet. Confirm the camera accepts a 12V DC input and that the adapter connector fits the camera power jack. Ensure cable length and network layout meet your installation needs. This adapter provides a simple, practical way to deliver 12V power and Ethernet data to security cameras from a 48V PoE network, reducing installation complexity and cabling requirements.
