Hello Kasito. As an Aussie I'm uniquely unqualified to answer this but what the hell. If you are looking at PoE power every camera should have a wattage rating in the specs list, usually with a max and average rating. Most cameras are fine with any PoE switch or injector (14ish watts max) but some cameras with heaters or PTZ require PoE+ (about 25 watts max from memory). The cameras specs should clearly state the temperature range and the max power requirements, this max should include heaters and motors running. If you are unsure and running cable before purchasing equipment I would recommend a Cat5e cable and a Figure 8 minimum. That way anything higher power you can put a 12VDC or 24VAC power supply onto the devices. I can't recommend cameras unfortunately, though I've hear tales that mobotix are used in the Antarctic and I believe I remember seeing footage from some cheap hikvision cameras filming a deer in the snow. Seemed pretty clear.

Hey. Unfortunately I've done something pretty silly. I've mixed up some firmware when updating a DS-7816-E2/8P NVR (chinese import that was running an early V3.0.X english firmware). I've used firmware from the 7600 range. Now the NVR is in a constant boot cycle, it gets the the Hikvision logo, beeps for a while and reboots. Anyone have any advice or can point me to any sites that can help? I've found plenty of stuff on IPC's but not much on NVR's. Or have a I really stuffed it up?
