Surveillance Storage

NAS-based surveillance records security-camera footage to shared storage, while an NVR (network video recorder, the device or software that manages camera recordings) is purpose-built for surveillance and cloud cameras store footage with a provider. For Australian homes and small businesses seeking control over their recordings without an ongoing cloud-storage subscription, a NAS can be a flexible option, but it is not automatically the best fit for every camera system.

This guide is for households and small businesses that want cameras recording to storage they control and need to decide whether a NAS, dedicated NVR or cloud service best suits them.

In 60 seconds

What to know before you plan this setup

A suitable surveillance-storage plan starts with three practical questions. Answer these before comparing hardware.

1

Recording approach

Decide whether you want flexible shared storage, a dedicated recorder or a provider-managed cloud system.

2

Camera compatibility

Check that existing or planned cameras can connect to the recording platform you intend to use.

3

Storage and retention

Estimate capacity from camera count, recording settings and how long you want footage available.

Which of these is you?

Where are you in the decision?

Start with the situation that most closely matches what you are trying to solve.

1

Choosing between NAS, NVR and cloud

Compare ownership, convenience and flexibility before committing to a recording platform.

2

Planning a NAS purchase

Check camera compatibility and estimate surveillance capacity before comparing suitable NAS options.

3

Setting up cameras you already own

Plan the network, recording software, storage layout and access controls as one system.

4

Storage fills sooner than expected

Revisit recording settings and retention goals before assuming that more capacity is the only answer.

FAQ

Common questions

A dedicated NVR may be the simpler choice when surveillance is its only job, while a NAS can suit readers who also want flexible shared storage and supported recording software. If you choose the NAS path, continue to the Australian surveillance NAS buying guide.

Capacity depends on factors including the number of cameras, recording settings and desired retention period. Use the calculator in the CCTV storage requirements guide for the detailed estimate rather than relying on a broad rule of thumb.

Not necessarily. Compatibility depends on both the cameras and the recording software available for your chosen NAS. Follow the NAS surveillance camera compatibility guide before purchasing or configuring the recorder.

Choose a practical retention period based on how quickly you are likely to discover an incident, available capacity and any obligations relevant to your circumstances. See the home CCTV footage-retention guide for fuller Australian context.

Confirm compatibility and capacity first, then use the NAS surveillance setup guide to plan cameras, recording software and storage.
