Getting my 'feet wet' regarding security cameras. I have a Dahua DHI-NVR4208-8P-4K with 4TB hard drive. Version 3.210.005.0, build date 2016-06-14. I would like to upgrade the firmware. Can someone please give me detailed instructions that are understandable by a 80 year old guy (me!!!)?
Which NVR is preferred: NVR4208-8P-4KS2 or NVR5208-8P-4KS2. I am planning to use 1 each HDW5831R-ZE, 1 each HDW4831EM-ASE, 1 each HDW5442TM-AS, 1 eachHDW5442TM-AS-LED, and 1 each HDW2431TM-AS-S2. Are all these cameras compatible with the NVR's?
