Hello there, i purchased a lorex costco kit about 4 years ago, when they use to be oem'ed hikvisions. It was the LNR200 series nvr and cameras but now i'd like to upgrade to 2.1mp or higher cams from MILKISBAD. I'm wondering if i can salvage any of the lorex bullet cameras and use them with any LTS NVR's. From what i understand they might not be ONVIF compliant but i figured since theyre hikvision rebrands they might still function properly with LTS nvrs. thanks.
