Is There A Hikvision (Or OEM) NVR That Can Record 70 Cameras At 3MP At The Same Time?

What's the target bandwidth or bitrate estimated (CBR or VBR) and storage requirement days or HDD capacity?

This should do the trick. There is a128ch and 256ch. Both can come with 6 extra HDMI if needed, but it increases the price too.

There is a 16bay and 24 bay version.
