Lorex NVR and Hikvision camers, doable?

[OrangeSVTguy 0]

Bought a Lorex LNR-6108-N NVR. I’m wanting to use my Hikvision IP cameras but they’re not showing up on the device list and even after manually adding them. Is there a certain firmware I should be running on the cameras and/or NVR to be successful?

 

I like my Hikvision Dome cameras as they’ve held up great in the elements so I really don’t want to buy additional bullet Lorex cameras to get this to work.
