Recording approach
Decide whether you want flexible shared storage, a dedicated recorder or a provider-managed cloud system.
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.
A suitable surveillance-storage plan starts with three practical questions. Answer these before comparing hardware.
Decide whether you want flexible shared storage, a dedicated recorder or a provider-managed cloud system.
Check that existing or planned cameras can connect to the recording platform you intend to use.
Estimate capacity from camera count, recording settings and how long you want footage available.
Start with the situation that most closely matches what you are trying to solve.
Compare ownership, convenience and flexibility before committing to a recording platform.
Check camera compatibility and estimate surveillance capacity before comparing suitable NAS options.
Plan the network, recording software, storage layout and access controls as one system.
Revisit recording settings and retention goals before assuming that more capacity is the only answer.
Use the dedicated CCTV storage calculator to estimate capacity from camera count, resolution and retention days.
Purpose-built for surveillance sizing, using camera count, resolution and retention days rather than general capacity math.

Need to Know IT uses a documented evaluation process, cross-checks claims against official documentation and keeps guides updated for Australian pricing and availability.
There are no sponsored rankings and no paid placements in editorial recommendations.
Advice is framed around the products, prices, retailers and risks Australian buyers encounter.
Product and software claims are cross-checked against vendor documentation rather than repeated from listings.
Guides in this hub are revisited as products, prices and the underlying decision-stage taxonomy change.
Affiliate or advertising relationships do not determine the order of recommendations.
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.
