I bought a new nvr from Andy, nvr5232-16p-4ks2e. To replace my qsee system. I know I have two Chinese to English hacked cameras that won't work with new nvrs. When I bought them the seller said can't be upgraded, won't work with 4k nvrs. So my plan was leave them attached to qsee, till I can replace them. Hooked the other cameras up to new nvr . One camera with I purchased from Costco or bjs. Failed to connect, when I reattached it to the qsee nvr , it still won't work, doesn't even show as plugged in. I know the new nvr prevent connection with Chinese regional cameras. But doesn't it actually cause the cameras to be unusable?
