Unifi USW flex distance

I am planning to connect a USW-flex to USW PRO 48 POE. The distance between them is 90 metres (CAT 6). The flex switch will be powered using the POE++ port from the switch. I now want to power three cameras (each 12w) from this flex switch which are at a distance of another 90 metres from the flex switch. Total distance between 48 port poe switch and cameras thus becomes 180 metres (cat 6).

is this possible ? what do I need to take care off.

Not something I have tested but if that did work, not sure how well it would work over time. The first 90M is fine, it’s the second 90M running three cameras I am not so sure about.
