L7805CV 5V Voltage Regulator to IP camera over POE

I am having a problem with getting my IP cameras to work over my home-made POE cable.

The parts I made in order to have POE are the following:

• L7805CV 5V Voltage Regulator (for input to the IP Cameras 5v/ground pin. 12V -> 5V) link: http://www.ebay.com/itm/L7805CV-5V-V…item2a259974bb

• 12V 2A DC Power Adapter Supply For CCTV Camera US (for use on the opposite side of the IP camera to inject into the ethernet cable) link: http://www.ebay.com/itm/12V-2A-DC-Po…item4604a8bda9

• Night vision Waterproof Outdoor Wifi Wireless WIFI IP Camera IR 24 LED M-JPEG (The IP camera itself) link: http://www.ebay.com/itm/180810824039…039%26_rdc%3D1

• Power over Ethernet PoE Adapter Injector + Splitter Kit (to hook up between the switch and the IP Camera) link: http://www.ebay.com/itm/160680383412…84.m1423.l2649

• 1000Ft Direct Burial Waterproof Cat 5e Outdoor UTP CMX (used from the switch [garage] to the IP Cameras [outside]) link: http://www.ebay.com/itm/1000-Ft-Dire…vip=true&rt=nc

Now the power supply that comes with it says this:

INPUT: 100-240V- 50/60Hz 0.4A max
OUTPUT: 5V 2A

I noticed when I hook up the original power supply to it-it does not power on. I'm just guessing its because I have the 5V Voltage Regulator in there and its feeding it less than 5V?

But once I connected it up using the POE injectors it works just fine (tested with a ethernet cable about 10ft long or so). Now that I placed them outside I have (again guessing) about ~120ft of ethernet cable from one tree IP Camera to my garage. It's using the direct burial ethernet cable for this (the original test was using a standard ethernet cable).

The power is coming from the 12V 2A DC Power Adapter Supply hooked into the POE injector. From there the POE injector is hooked to the switch and the other end to the direct burial ethernet cable that's going outside to the IP Camera. At night I can see the glow of the red IR LEDs so I know it's getting power. And I also see that its blinking (green led) on the switch so I know it's communicating… But when I try to find its IP on my router it does not show up at all?

And again, I tested this out using the 12V 2A DC Power Adapter Supply/ POE injector and a standard 10ft ethernet cable and it worked just fine.

I tested the voltage with a volt meter to make sure it was getting enough from that long run. I had 12V on one side (the garage) going through the injector/ethernet wire and on the other end (outside at the other injector from the ethernet) I had about 12.4V constant so it really did not drop at all from that 150ft ethernet run.

I also tested to make sure my crimping on the ends of the ethernet were correct (had a gizmo that sent out a signal and showed me what order the wires are in). They all came back the same.

So what all should I try testing out first? Second? Third? I already heat shrink all the connections outside so I hope I don't have to pull those apart to disconnect the POE/splitter!
