Hard Drive Capacity Guide

The right CCTV hard drive capacity depends on how many cameras are recording, whether recording is continuous or motion-based, and how long you need to retain footage.

Hard Drives for Network Video Recorders

CCTV hard drives are commonly installed inside compatible NVRs and DVRs to store recorded security footage. A surveillance-grade hard drive is a better choice than a standard desktop drive for systems that record for long hours or operate continuously.

• NVR recording – Store footage from IP cameras connected to a network video recorder.
• DVR recording – Support compatible analogue or HD-over-coax recording systems where applicable.
• Continuous recording – Suitable for systems recording around the clock.
• Motion recording – Can store footage triggered by motion detection or event-based recording.
• Playback and export – Allows users to review incidents and export footage where supported by the recorder.
• System upgrades – Increase storage capacity when adding cameras or extending footage retention.

How to Choose the Right CCTV Hard Drive

Choosing the right surveillance hard drive helps maximise recording reliability and storage performance. Before ordering, review your CCTV system design and recording requirements.

• Check recorder compatibility – Confirm the NVR or DVR supports the hard drive capacity you want to install.
• Count the cameras – More cameras require more storage, especially when recording continuously.
• Review camera resolution – Higher-resolution cameras use more storage space.
• Consider frame rate and compression – Recording settings affect storage use and retention time.
• Decide on retention period – Work out how many days or weeks of footage you need to keep.
• Allow for future expansion – Choose extra capacity if you plan to add cameras later.
• Use surveillance-grade storage – Select hard drives designed for security recording rather than standard desktop use.
