I use a simple cable tester to test connectivity. If the cable passes that test, the RJ-45 wiring is correct. However, that doesn't guarantee that data transfer is up to the standard. To test data transfer rate, you need an advanced cable tester or if you can mirror the ports and capture TCP/IP dump to see if packets are dropped. This always seems to be more than what a typical user can do.
To simplify the test, you should take the cam off your mounting location, bring it close to the switch, hook it up with a 6 ft cable, and see if the cam goes on and off again. If the cam works fine with a 6 ft cable, chances are your wiring is faulty.
If your wiring is faulty, check if there are any kinks, bends, sharp turns, and tangles along the way and straight them out. Also remove the two RJ-45 connectors and make new ones. Some times, the contacts at the RJ-45 don't make good contacts with the wires inside the RJ-45 and that causes a bad connection.
Hope this helps.
