Networking Noob Question Regarding PoE Class and Max Wattage

I have been researching regarding setting up IP Cameras for my business and have been looking at using PoE for the cameras, I am confused regarding some details regarding this.

I am currently looking at the TP-Link SL1226P PoE switch (max PoE: 250w) and the VIGI C230 IP Cameras. The VIGI cameras have a max wattage of 5.5W but has a PoE class of 0. From my research, if computing only the 5.5W max wattage, even if I populate all 24 ports of the SL1226P with C230 cameras, I will still be under the power limit. However, researching PoE classes, since it is a class 0 device, an unmanaged switch will usually reserve the max of 15.4W, which means I will not be able to populate all 24 ports as power allocation will not be enough.

Does anybody know if the unmanaged switch will automatically adjust the reserved wattage of each port to around 7W for the cameras or will it just reserve the max wattage of the PoE class?

Some google results have shown that going managed is better at this as you can set PoE to power limits, e.g. setting all ports to 7W, instead of using the base PoE class 0 of 15.4W. Any advice about this?

Thank you.
