Geovision GV-HDD-391 4TB Surveillance Hard Drive

Overview

The Geovision GV-HDD-391 is a 4TB surveillance-grade hard drive built for continuous 24/7 recording in NVR and DVR systems. Unlike consumer drives, this unit is engineered to tolerate the thermal and mechanical demands of non-stop video workloads—meaning longer mean time between failures (MTBF) and stable performance across extended recording cycles. Deploy this drive when you need reliable multi-camera storage without premium pricing, or when retention windows of 15–30 days across 4–6 camera feeds are your baseline requirement.

Compatibility

The GV-HDD-391 integrates directly into Geovision NVR and DVR platforms via standard SATA connectivity. It also works with third-party ONVIF-compliant recording systems and any standard SATA-based storage enclosure used in security deployments. When sizing capacity, calculate retention based on your bitrate and desired archival window: a 4TB drive typically supports 15–30 days of 1080p recording from 4–6 cameras, depending on frame rate and compression codec (H.265 vs. H.264). This makes the GV-HDD-391 practical for medium-to-large single-site or multi-site deployments where bulk purchasing standardizes storage across heterogeneous systems.

Installation Notes

Install the drive into an available SATA bay in your NVR or DVR enclosure, ensuring proper thermal clearance and air circulation—surveillance-grade drives dissipate continuous heat differently than consumer units, and cramped bays accelerate wear. Verify your NVR firmware recognizes the drive capacity before configuring recording profiles; some legacy systems may require a firmware update to unlock full 4TB addressability. No special tools beyond a standard SATA cable and power connector are required.
