hybrid

Where in the product specifications would it be shown If an NVR needs a separate PoE switch to power the cameras? For example, I need a hybrid HDCVI DVR and was looking at the Dahua X82B2A; looking at the spec sheet, it's I'm not sure if has integrated PoE ports (but I suspect it does not)...

I forgot my starlife dvr password. I am trying to reset dvr by removing cmos battery but i cant do it. Please help me
