PoE budget check

Cameras this switch can power at a typical draw per camera, using the 48 W budget and 4 PoE ports.

Power per camera Cameras Power used Limited by
4 W 4 16 W of 48 W Port count
6 W 4 24 W of 48 W Port count
8 W 4 32 W of 48 W Port count

Check each camera’s maximum power consumption in its datasheet; infrared at night and heaters raise it. Leave some headroom rather than loading the budget to the limit.
