His solution makes it extra cheap by using so-called passive PoE, which injects a voltage onto the conductors of the network cable being used ... is mostly spent on wiring and heatshrink ...

An IEEE standard for powering network devices via Ethernet cable. Also known as "Power-over-Ethernet" (PoE), the 802.3af specification provides 48 volts over 4-wire or 8-wire twisted pair.

Ethernet & PoE via two-wire cable. Using the Mx2wire+ system from MOBOTIX, an Ethernet network with PoE can be established using existing cables up to 500 m. This means that you can utilize a two-wire ...

This system integrates power and data transfer through a single PoE LAN cable, eliminating the need for separate electrical wiring or battery replacements. The design simplifies installation ...

Power over Ethernet gives you the benefit of a rock-solid wired connection without the need of separate power cabling. Then there’s the matter (sorry for the pun) of the PoE motor’s Matter ...
