Frequently Asked Questions

Q: What is a passive PoE splitter and injector adapter, and how does it work?

A: A passive PoE (Power over Ethernet) splitter and injector adapter allows you to transmit both power and data through a single Ethernet (RJ45) cable. The injector adds DC power from a power supply into the Ethernet cable, while the splitter at the other end separates the power and data signals — delivering power directly to your IP camera or device without needing a separate power outlet near the installation point.

Q: Is this PoE adapter compatible with my IP camera or PoE switch?

A: This adapter is compliant with IEEE 802.3af/at standards, making it compatible with the vast majority of PoE-enabled IP cameras, switches, and access points. It supports both standard power pin configurations (1/2+, 3/6− and 4/5+, 7/8−) and automatically detects connected devices before enabling power input for added safety.

Q: What is the maximum cable run distance supported by this PoE adapter?

A: This PoE splitter/injector supports a maximum data and power transmission distance of up to 150 meters, though actual performance may vary depending on the quality of the RJ45 Ethernet cable used.

Q: What voltage options are available for this PoE adapter?

A: Multiple output voltage styles are available, including 12V, 24V, and 48V, making this adapter suitable for a wide range of IP cameras and PoE-powered networking devices. Please select the correct output voltage for your specific device requirements before purchasing.
