§ 01Overview
What the DHI-NVR608R-64-4KS2 is
The Dahua DHI-NVR608R-64-4KS2 is a 64-channel 2U Ultra-series network video recorder built as a high-capacity recording workhorse.
An Intel quad-core processor drives 384 Mbps of record bandwidth across up to 64 cameras at resolutions up to 12MP with H.265 compression.
Eight hot-swappable SATA III bays take up to 8TB per drive and support RAID 0/1/5/10 with a global hot-spare, so recordings survive a drive failure and you can replace a drive without downtime.
A redundant power supply means a single power module can fail without stopping recording, which is the key reason to choose the R model over the 608H.
This is a 4KS2 Ultra-series recorder focused on reliable, large-scale recording and playback rather than heavy on-recorder AI.
It handles motion detection, video loss and tampering, basic IVS and event triggers, but it does not run the SMD Plus, face recognition or AcuPick analytics found on the newer WizSense and WizMind AI recorders.
Smart detection on this system comes from the cameras, so pair it with capable Dahua AI cameras if you need people and vehicle classification, and the recorder stores and plays back those streams reliably.
There is no built-in PoE, so cameras connect over the network through external PoE switches sized to your load, which is standard at this channel count.
Two RJ-45 gigabit ports can run bonded or independently, and dual HDMI plus VGA outputs drive control-room monitors.
A hard drive is not included; fit surveillance-grade drives across the eight bays for your retention needs.
