@Wayne-TP so you mean, if I have 6 tapo cctv (C520WS), and I want to have 24/7 recording, best option is use VIGI NVR?

I see. This is because i was looking at HDD surveillance, but found it only available for 3.5" only. And I read a lot users complaining the drive 2.5" is very hot. So, thinking of using 3.5" instead...

I have total 6 cameras, C520WS. I wish to connect them to Tapo H500 (and each of them still having 64GB sd card). I notice some people say H500 only allow maximum 4 camera connect with 24/7...

@Wayne-TP for the H500, can we use 3.5 HDD enclosure which has its own dedicated power supply and then connect it via SATA to the hub? Will it work?
