Frequently Asked Questions

Q: What PoE standard does this 48V power injector support?

A: This PoE power injector is fully compatible with the IEEE 802.3af and IEEE 802.3at standards, making it suitable for a wide variety of PoE-enabled devices including IP cameras, wireless access points, and VoIP phones.

Q: Can I use this PoE injector with my CCTV surveillance camera system?

A: Yes! This 48V 24W desktop PoE power injector is specifically designed for use with CCTV and IP surveillance cameras. It delivers both data and power over a single Ethernet cable, simplifying your installation.

Q: Is this PoE adapter compatible with international power outlets?

A: Absolutely. The injector accepts a wide AC input range of 100V–240V at 47–63Hz, making it compatible with power outlets around the world. No voltage converter is required for most countries.

Q: What does it mean when the LED indicator light turns off?

A: When the LED indicator light is on, the injector is working normally. If the light turns off, it signals a fault condition — such as a short circuit, overload, excessive consumer power draw, connected device failure, or a cable short circuit — allowing you to quickly identify and address the issue.

Q: Does this PoE injector include surge and spike protection?

A: Yes. The anti-surge design is rated to withstand 5KB positive and passive electric surge waves (8/20µS waveform) up to 5 times per minute. Additional protections include over-voltage, under-voltage, over-current, over-temperature, and short-circuit safeguards for comprehensive device security.
