Hikvision DS-7764NI-M4 – 64-Channel 1.5U 8K Network Video Recorder
The Hikvision DS-7764NI-M4 is a 64-channel 1.5U NVR built for large-scale installations that need high resolution and extensive storage in one unit. Specifically, it accepts up to 64 IP camera inputs at resolutions up to 32 MP, and since it carries no built-in PoE ports, all cameras connect through an external network switch. As a result, installers should plan switch and cabling infrastructure separately from the recorder itself.
In addition, the recorder outputs video at up to 8K resolution over HDMI, and a second independent HDMI port supports dual 4K displays for split monitoring setups. Meanwhile, four SATA interfaces accept drives up to 16 TB each, giving up to 64 TB of total on-device storage. Furthermore, dual-stream recording and H.265+ compression keep bandwidth and storage use efficient even with a large camera count. On top of that, built-in POS integration overlays transaction data on live view and playback, while extensive alarm inputs and outputs support integration with external sensors and access equipment.

Who This NVR Suits Best
- Large retail chains and supermarkets – POS integration overlays transaction data on footage, letting managers cross-reference sales with camera activity at tills.
- Data centres and control rooms – the 8K HDMI output and dual-display support suit environments needing high-resolution monitoring walls.
- Enterprise sites with structured network cabling – organisations that already run PoE switches or media converters can connect the full 64-camera capacity without depending on the recorder for power.
