First time newb here. I recently bought a Swann NVR kit from Sam's Club that came with a Swann NVR8-7300 and a couple NHD-815 cams. I read that Hikvisions cams could potentially work with Swann NVRs and decided to buy first, ask questions later. Plugging the Hikvision cam into the Swann NVR didn't bring anything up. I could log into the Hikvision camera when connected directly to my router, but can't figure out how to get it to show up on the Swann NVR. Help!?!
