Looking for outside AX device with PoE passthrough

I am looking for an outside AX unit that is able to pass active PoE to my webcams that are mounted right beneath the AP.

The WAP AX do not pass PoE. Only the CAP AX would fit, if it would be somewhat waterproof and smaller.

Question: Is there any known hack to solder something on the WAP AX in order to pass PoE to the second Ethernet port?

You used webcams (plural).
Mikrotik devices tend to have very low PoE output (Amperes are limited), so determining the needed power budget Is anyway important.
Powering:
1 webcam, OK.
2 webcams, maybe.
3 webcams, improbabile.

This said, you might want to explore the possibility of using a multi-port outdoor PoE extender.

Everything Is of course possible, but the extents of modifications needed to the Mikrotik device to allow pass through PoE (that will btw obviously be outside the control of RoS) are (IMHO) simply not worth the 30-60 €/$ that an added extender device might cost.
