Frequently Asked Questions

Q: What is a 4-Port PoE Injector and what does it do?

A: A 4-Port PoE (Power over Ethernet) Injector allows you to deliver both data and DC electrical power through standard Ethernet cables to up to 4 connected devices — such as IP surveillance cameras, wireless access points, or outdoor network bridges — without needing separate power supplies at each device location.

Q: What input voltage does this PoE injector support?

A: This injector supports a wide DC input voltage range of 9V to 48V, making it compatible with standard DC power adapters, solar charge controllers, and 12V/24V/48V battery bank systems — ideal for both grid-tied and off-grid installations.

Q: Can I use this PoE injector with a solar panel system?

A: Yes! The wide 9–48V DC input range makes this injector an excellent fit for solar-powered setups. Connect it to your solar charge controller or battery bank output to power remote surveillance cameras or wireless network bridges in off-grid locations.

Q: Is this PoE injector compatible with all PoE-enabled devices?

A: This injector is designed to work with passive PoE devices. Please verify your connected device's PoE voltage requirements before connecting, as active 802.3af/at devices may require a standards-compliant managed PoE switch for full compatibility.

Q: Do I need special tools or software to set up this PoE injector?

A: No special tools or software are needed. This is a true plug-and-play device — simply connect your DC power source to the input, then run your Ethernet cables from the injector ports to your PoE-compatible devices and you're ready to go.
