The GEOVISION 391-HDD4TB-000 is a 4TB surveillance-grade SATA II hard drive designed for continuous-duty recording environments. Unlike standard desktop drives, surveillance-grade drives are engineered to handle the high write cycles and 24/7 operation demands of security and monitoring systems. This drive is intended for installation inside digital video recorders, network video recorders, and compatible surveillance storage enclosures. Installation is typically performed by security system technicians or IT professionals managing networked video infrastructure.

This drive is suited for use in surveillance and security recording systems that require reliable, high-capacity storage. At 4TB, it provides extended recording retention for multi-channel video setups in both residential and commercial installations. Its SATA II interface makes it compatible with a wide range of DVR and NVR platforms that accept standard SATA hard drives.

Installation Notes

Hard drive installation should be performed by a qualified technician familiar with static-sensitive components and data storage systems. Power down and disconnect the recording unit from all power sources before handling or seating the drive. Use appropriate anti-static precautions when handling the drive. Verify that the host DVR or NVR firmware supports the 4TB capacity before installation.
