I have a qc8116 nvr, bought from Costco years ago. 15 hardwired cameras .5 to 4mp. Each. One wifi 3mp. Works ok, recent changes to neighborhood "urbanization " have given me my first prowler in 25 years. . Time for upgrade. Would like to add 10 or so more cameras, be able to see from internet, and record in full resolution 24/7. Nvr still works can I keep it and just add a newer one with more capacity, or buy a desktop to use blue iris on. Any suggestions appreciated. Cost not my main concern. Still don't like to waste money.
