Hello,
Great write-up and pictures!
Could you maybe find out what is behind the sticker with the serial number that is blurred out? I think I can see 2 IC's there.
The reason for asking is that I want to modify the PoE circuit so it gets recognized as a class 2 (802.3af) device. For this it needs to pull around 18 mA during the signature phase. (https://en.wikipedia.org/wiki/Power_over_Ethernet#Configuration_via_Ethernet_layer_2_LLDP) My Netgear GS105PE switch otherwise refuses to send power to the camera because I suspect it to have no signature at all, making it appear to the switch as a class 0 device, to which the GS105PE only supplies power when its fed by a 802.3at PD, which I do not have.
I was hoping that there would be something like a TI TPS2370 (http://www.ti.com/lit/ds/slus537c/slus537c.pdf) in there that just lacks the signature resistor.
