QNAP VS-4112U-RP-PRO+US 12-Channel 4-Bay Rackmount NVR with Redundant Power
Overview
The QNAP VS-4112U-RP-PRO+US is a 12-channel, 4-bay 1U rackmount network video recorder built for commercial and enterprise surveillance environments where recording continuity and rack-density matter. Powered by a dual-core Intel Atom processor, it supports up to 8-megapixel camera streams, five intelligent video analytics functions, and includes a redundant 250W power supply — the feature that puts it squarely in the conversation for any deployment where downtime is unacceptable. If you are specifying an NVR for a retail chain back-office rack, a mid-size corporate campus, or a light industrial facility, the VS-4112U-RP-PRO+US (often searched as VS 4112U RP PRO+US) deserves a close look before you settle on a single-PSU unit.

Key Features
- 12-Channel IP Camera Support: Handles up to 12 simultaneous IP camera streams at up to 30 fps in D1/VGA resolution, or up to 8-megapixel per channel for high-resolution evidence capture. That gives you the flexibility to mix standard-definition PTZs and 4K fixed cameras on the same recorder without buying separate NVRs.
- Redundant 250W Power Supply: The hallmark spec on this unit — dual PSUs in a 1U chassis mean a power supply failure does not stop recording. For any deployment with a service-level expectation (retail loss prevention, healthcare corridors, financial lobbies), this eliminates the single-point-of-failure that trips up single-PSU recorders.
- 4-Bay Hot-Swappable, Lockable Storage: Four 3.5
