Geovision 12TB Surveillance Grade Sataii Hard - 391-HD12TB-000

Geovision 391-HD12TB-000 12TB Surveillance Grade SATA II Hard Drive

Overview

The Geovision 391-HD12TB-000 is a 12TB surveillance-grade SATA II hard drive designed for continuous-duty operation in network video recorders and digital video recorders. Built to handle 24/7 recording workloads, this drive is engineered for the thermal and vibration stresses of multi-camera surveillance systems where standard desktop or consumer drives would fail within months. The 12TB capacity delivers long retention windows — roughly 30–45 days of 24/7 recording across a modest camera set depending on resolution and compression — before overwrite or archival, a critical factor for systems requiring evidence preservation or compliance-driven retention policies.

Compatibility

This drive is compatible with Geovision DVRs and NVRs that accept 3.5-inch SATA II drives, as well as many third-party surveillance systems supporting standard SATA interfaces. Verify your recorder's drive bay specifications and firmware compatibility before installation. The SATA II interface operates at 3 Gbps — sufficient for sustained multi-stream recording but not a bottleneck for typical surveillance throughput. Not intended for hot-swap or RAID configurations without explicit system design; consult your recorder manual for supported drive configurations.

Installation Notes

Install the drive into a horizontal bay to minimize vibration coupling. Ensure the recorder's internal cooling provides adequate airflow around the drive enclosure — surveillance-grade drives generate heat during continuous operation and rely on forced ventilation to maintain operating temperature. Do not install in vibration-prone environments (industrial floors, near machinery) without vibration isolation. Use standard 3.5-inch SATA mounting rails and secure with provided or standard screws. Allow 30 minutes for the drive to stabilize before powering on the recorder; this reduces mechanical stress during first spin-up.
