Hello from AZ... My question is most likely about cam resolution and/or PTZ. I need to observer a solar controller screen (3-4" wide LCD) and related equipment ideally from about 6' away. Indoor out of weather. PTZ would be nice to observe other equipment in room. From 6' would I need 1080p, 2K, 4K? I have a light to illuminate the LCD screen. WiFi or hardwire OK as there's a router nearby. Priced low-moderate. Thanks for any suggestions.
