Recorders with 802.3af PoE output

802.3af

— the oldest active PoE power format in use today. It provides power at the power output up to 15 W (at the input of the consumer — up to 13 W), output voltage 44 – 57 V (at the input — 37 – 57 V) and current in a pair of supply wires up to 350 mA. Despite the "venerable age", it still continues to be widely used; so there are still quite a lot of registrars working only with 802.3af on the market (as of the end of 2021). However, it is worth considering that this standard immediately covers 4 so-called power classes (from 0 to 3), which differ in the maximum number of watts at the output and input. So when using 802.3af, it doesn't hurt to make sure that the output power will be sufficient for the selected load.
