How to use

Install the drive into a compatible 3.5-inch bay in your DVR, NVR, server or desktop enclosure and connect using a SATA III compatible cable to the motherboard or controller. Ensure proper mounting to minimize vibration and allow airflow for cooling. Initialize and format the drive within the host system according to the recorder or operating system instructions, then configure storage settings such as recording schedules, overwriting behavior and partitioning as required for your surveillance workload.

Usage recommendations

For reliable long-term surveillance recording, use the drive in systems with appropriate cooling and power management. Match recording bitrate and retention settings to the drive capacity and supported workload; in multi-drive or RAID configurations, follow the enclosure or NVR vendor guidelines for compatibility and redundancy. Periodically monitor drive health through the host system and schedule backups or archival of critical footage to prevent data loss.
