The device in focus is a high-practical 4-Port 10/100M Passive POE power supply, engineered to
deliver remote power to up to 4 terminal devices via Ethernet wiring—extending transmission distance
to 100 meters (328 ft) while maintaining stable 10/100M data connectivity. As a dedicated 4-Port 10/100M
Passive POE power supply, it serves as a cost-effective solution to add PoE capabilities to any non-PoE
Ethernet switch or router, eliminating the need to replace existing network infrastructure.
This 4-Port 10/100M Passive POE power supply specializes in injecting electrical power into CAT-5, CAT-6,
or CAT-7 Ethernet cables, leveraging the passive PoE transmission mechanism: standard Ethernet uses 2
of the 4 twisted pairs for data, while this device utilizes the unused 4/5 pins for positive power and 7/8 pins
for ground—ensuring no interference between power delivery and 10/100M data transmission. Each of its
4 ports operates independently, providing consistent passive power to connected devices without mutual
signal disruption, making it ideal for scenarios requiring multi-device power centralization.
Widely compatible with popular network equipment, the 4-Port 10/100M Passive POE power supply is perfectly
suited for powering IP cameras (dome, bullet, or small PTZ models), IP videophones, WiFi access points, and
other passive PoE-enabled devices. Its 4-port design allows simultaneous power supply for a small-scale device
cluster—such as a 4-camera retail surveillance setup or a multi-point office WiFi network—streamlining deployment
by centralizing the power source.
Designed for ease of use and cost efficiency, this 4-Port 10/100M Passive POE power supply supports plug-and-
play operation with no software configuration required. It eliminates the need for separate power adapters and
extra wiring, drastically reducing material costs and on-site installation manpower. Whether deployed in small
businesses, residential communities, or retail stores, it combines 10/100M data compatibility, 4-device power
capacity, and passive PoE reliability to offer a flexible, budget-friendly solution for extending power and network
connectivity to distributed edge devices.
