Record 32 Cameras in True 8K
This Hikvision 32 channel NVR handles up to 32 IP cameras at once, recording at a max resolution of 32MP. The 8K HDMI output delivers ultra-sharp live view and playback on a single monitor.

That means weeks of continuous recording without swapping drives. Lower hard drive spend and less maintenance — a direct win for your bottom line.
