I wouldn't think so. No different than hooking another switch off one of the ports of the VLAN switch.
Looking at this thread again and was curious if anyone has used the Lortya/Linovision POE extender with cameras that use higher wattage? I'm going to replace my HFW5241E-Z12E for LPR duties with Andy's version of the TC237-PW6M-IRLZF1050-B . The specs for the Z12E says it uses less than 10.3 watts while the 237 less than 20 watts, and both cameras are 802.3af. I'd like to keep the Z12E as an overview camera and was wondering if the Lortya/Linovision POE extender--assuming I powered it with its own 60w watt injector, would do the trick. As an aside, Dahua's website shows the Z12E available in black now, which I hadn't seen before.
With my same PoE extender, it is now (before dawn) drawing 5.7W, using the IPC-HFW5231EZ5 and a 4MP Amcrest.
I guess what I'm wondering is whether a device that pulls, say, 18 watts, will be operational using the splitter when paired with another cam that pulls less than 10 watts. You mentioned the two cams that you have needed a 60 watt power source. I'm wondering whether the power being split by the extender is the full 60 watts from the injector, a poe+ rated 30 watts, or something less.
With the power required by the extender, I'm wondering if, in your case, you're working with a maximum of 30 watts per the poe+ maximum. Even with the 5.7w used by the extender, you'd have plenty left to power the two cams you're running. I won't be able to test it for a couple more days, but I'm wondering if the maximum power that the extender will draw--regarding of the wattage of the injector--is 30 watts. Have you bench tested a PTZ with a regular cam and the extender?

The specs on my own Z12 say power consumption is 3.2W, and 10.3W with IR on. In my daytime configuration, I have the illuminator set to "ZoomPri" at 100%, and am consuming only 3.63W. The PoE splitter says the max. is 8W per device, while the splitter itself consumes <=3W. Hope this helps.
You are slightly exceeding the threshold of what the specs say the PFT1300 will support. In fact, the datasheet for the Dahua/Loryta model (PDF attached) doesn't explicitly state this, but the Amazon ad for the Linovision version () does. Specifically, it says:
"POE Output: 2*10/100 Base-T RJ45 ports; CAMERA Port: compliant to IEEE802.3af POE standard, max 8W power consumption; OUT Port: compliant to IEEE802.3af/at POE+ standard, max 16W power consumption"
If you are able to connect a PTZ drawing more than 16w, please report back as I had been planning to use this topology to have a PTZ and an Overview from a single cable, but am now looking at having to run a new cable.
