Yeah up to 30 watts, but it maxes out at 96 watts total.
Do the math...96 watts and 10 ports, 96/10 = 9.6 watts total per port if all used and that is what takes priority over up to 30w at each port.... You will not get 30 watts per port if a camera is connected to each port. You may get 30 watts on 3 ports, but then the remaining 7 will have no power left.
Now with everything plugged in, some of the fixed cams would be using less than 9.6 watts, so the port to the PTZ would get anywhere from 9.6 watts up to 30 watts, but the total load of all the ports cannot exceed 96 watts.
So it depends on what else you have on the POE switch. You need to go at the spec sheets of what you have or will have and ensure that the thing can handle it.
You have this PTZ and looking to get another. At night with IR on, that right there is about 48 watts of the 96 watts, so that leaves you with roughly 48 watts or roughly 6 watts per the remaining 8 ports. That may or may not be enough to run everything. Especially at night.
Many people do not consider the total watt budget on these switches and then they hook a camera up to every port and at night it is reboot city of the cameras because they are drawing too much and the camera reboots.
