Dahua NVR NVR4XXX-4KS2 upgrade to 8 Channel

You will do it again.....just get a 16.

If you get a 16 and never load it up at least you will have more encoding power. Some of the NVRs have crap FPS on higher resolutions or a few 4K cams and all the sudden you are at 80% cpu capacity.

I sold my 16 and got a 32. I was already at 14 cams and I'm pretty sure some day, I would go beyond 16.

That's right. Dahua definitely uses different CPUs depending on the number of channels and Mbps throughput.
 
Had a 8, gave to a friend to get started. Then bought a 16. Had the cpu load problem with 5-6 high res cams. Sold that one and bought a NVR6a08-32-4ks2. I have grown to 18 cams with my last cam, a 25x zoom starlight ptz with auto tracking.

Get the 32. Just when you think, "Ahhh, 16 is enough..." And then it isn't. Buy the non-PoE version and use your own switch(es) since the 32 channel PoE version still only has 16 ports.

Chào,

Có cách nào để nâng cấp NVR "4 Kênh" của tôi lên "8 Kênh" không?

BR,
