NAS Surveillance Setup Guide — Cameras, NVR and Storage Australia

A NAS can replace a dedicated NVR for most home and small business surveillance setups. And it does a better job of it, combining camera recording with file storage, remote access, and long-term retention on a single device. The key decisions are choosing the right NAS platform and software, sizing your storage correctly for continuous recording, and selecting cameras that are compatible with your NAS vendor's surveillance app. This guide walks through every step, with AU pricing and Australian-specific context throughout.

NAS vs Dedicated NVR: Which Makes More Sense?

A dedicated NVR (Network Video Recorder) is a purpose-built appliance that handles IP camera recording. It's simple to set up, usually ships with PoE ports built in, and does exactly one job. The tradeoff is that it does only that one job. Storage is fixed, software is proprietary, expansion is limited, and the footage lives in a silo.

A NAS running surveillance software gives you a platform that handles recording alongside file storage, media serving, backups, and remote access. When a camera slot opens up, you add it in software. When you need more storage, you add drives. When the retention window needs extending, you expand the pool. For anyone already running a NAS. Or planning to. It's almost always the better long-term investment.

The cases where a dedicated NVR still wins: very simple setups (2-4 cameras, no interest in file storage), installations where the device must be completely locked down to a single function for security or compliance reasons, or where an integrator is handling installation and prefers a closed appliance.

Surveillance Software: Synology Surveillance Station vs QNAP QVR Pro

The two dominant NAS surveillance platforms in Australia are Synology Surveillance Station and QNAP QVR Pro. Both are mature, ONVIF-compatible, and support hundreds of IP camera brands. The choice usually comes down to which NAS platform you're already invested in. Or prefer.

Synology Surveillance Station is widely regarded as the more polished of the two. The interface is clean, mobile app (DS cam) is reliable, and the live view and playback experience is smooth. Synology includes two free camera licences with every NAS. Additional cameras require paid licence packs (currently around $75-$90 AUD per licence). For home users with 2-4 cameras, you're covered without spending anything extra. For 8+ cameras, licence costs add up and should be factored into the total cost.

QNAP QVR Pro is more feature-rich at the enterprise end, supports a wider range of analytics add-ons, and QNAP's QVR Elite subscription model offers an alternative licensing path. The interface is denser than Synology's, which suits experienced users but can be overwhelming for first-timers. QNAP also offers dedicated NVR appliances alongside their NAS range, so the ecosystem is broader if you need a mixed deployment.

Asustor AiVideos is worth mentioning for budget-conscious buyers. Asustor's surveillance app is free with no per-camera licence fees, which makes models like the AS3304T (from $585 at Mwave) attractive for setups with 8+ cameras. The platform is less mature than Synology or QNAP but functional for basic recording and playback.

Choosing IP Cameras for NAS Surveillance

Any ONVIF-compatible IP camera will work with Synology, QNAP, or Asustor surveillance software. ONVIF is the industry standard protocol. If a camera advertises ONVIF Profile S or Profile T support, it will connect. That said, cameras on each vendor's officially tested compatibility list will offer deeper integration: two-way audio, PTZ control, motion zone configuration, and intelligent event triggers that generic ONVIF cameras may not expose.

In the Australian market, the most commonly used camera brands with NAS surveillance setups are Hikvision, Dahua, Reolink, Axis, and Uniview. Hikvision and Dahua dominate the SMB integrator market on price. Reolink is popular for home users given the low entry price and solid Synology/QNAP compatibility. Axis is the premium commercial option with the best build quality and firmware security track record.

Key specs to check when selecting cameras for NAS recording:

• Resolution: 1080p (2MP) is sufficient for most applications. 4MP or 4K cameras produce larger files. Factor this into storage sizing.
• Compression: H.265 (HEVC) cameras store roughly half the data of H.264 at equivalent quality. If your NAS supports H.265 decoding (most current models do), prioritise H.265 cameras to extend retention.
• PoE vs wireless: Wired PoE cameras are strongly preferred for surveillance. Reliable, no battery management, no Wi-Fi drops. Wireless cameras are acceptable for temporary installs or locations where cabling is impossible.
• IP rating: Outdoor cameras should be IP66 rated minimum. IP67 is better for exposed locations.

Storage Sizing for Surveillance Workloads

Surveillance storage sizing is one of the most commonly underestimated parts of a NAS setup. The formula is straightforward but the numbers add up fast.

A single 1080p H.264 camera recording continuously at standard bitrate (around 2-4 Mbps) generates roughly 25-50 GB per day. At H.265 with similar quality settings, expect 12-25 GB per day. Multiply by camera count and desired retention period to get your raw storage requirement.

Cameras	Resolution	Codec	Retention	Storage Required
4	1080p	H.265	30 days	~1.4 TB
4	1080p	H.264	30 days	~2.9 TB
8	1080p	H.265	30 days	~2.9 TB
8	4MP	H.265	30 days	~5.8 TB
16	1080p	H.265	30 days	~5.8 TB
16	4MP	H.265	30 days	~11.5 TB

These figures assume continuous 24/7 recording. Motion-triggered recording can reduce storage consumption by 30-70% depending on activity levels. But for security-critical applications, continuous recording is strongly recommended. Gaps in motion-based recording have a habit of occurring at exactly the wrong moment.

Add a 20-30% buffer above your calculated requirement, and factor in RAID overhead. A 4-bay NAS running RAID 5 with four 4TB drives gives you approximately 10.9 TB of usable space. Enough for 8 × 1080p H.265 cameras at 30-day retention with room to grow. Note that NAS-grade hard drive prices have risen significantly from early 2025 levels. Drives that sat comfortably under $160 for 4TB NAS models are now consistently above $200. Factor current pricing into your build budget.

NAS Models That Suit Surveillance Workloads

Surveillance recording is a sustained sequential write workload. The NAS is constantly writing camera streams to disk while also handling read requests for live view and occasional playback. CPU matters here. Live transcoding for remote viewing (particularly on mobile over a low-bandwidth connection) is CPU-intensive, and simultaneous playback of multiple streams will tax a lower-end processor.

The practical minimum for a surveillance NAS is a quad-core processor with at least 4 GB RAM. Below are current AU-stocked models well-suited to surveillance at different scales.

Home Surveillance: 2-8 Cameras

Synology DS425+ (from $819 at Mwave, PLE Computers, Scorptec) is the standout choice for home surveillance. The DS425+ runs a quad-core Intel Celeron J4125 with 2 GB RAM (expandable to 6 GB), includes two free Surveillance Station camera licences, and handles 4-8 cameras comfortably once RAM is expanded. Four bays provide room to scale storage as retention requirements grow. Synology's Surveillance Station is the most polished NAS surveillance interface available, and the DS cam mobile app is reliable for remote monitoring.

QNAP TS-464 (from $989 at PLE Computers, Scorptec) is a strong alternative for users preferring QNAP's ecosystem. The TS-464 runs an Intel Celeron N5105 with 8 GB RAM stock and includes HDMI output for local monitoring. Useful if you want a live view screen without needing a PC. QVR Pro handles up to 8 cameras effectively on this hardware.

Asustor AS3304T (from $585 at Mwave) is worth considering if licence cost is a concern. The AS3304T runs a quad-core ARM processor and supports AiVideos with no per-camera fees. Processing power is lower than the Intel-based options, so keep expectations realistic for simultaneous live streams and transcoding. It suits homes with 4-6 cameras and primarily local playback.

Small Business Surveillance: 8-16 Cameras

Synology DS925+ (from $995 at Mwave, Scorptec) runs a quad-core AMD Ryzen R1600. A meaningful step up in processing power over the Celeron-based DS425+. With 4 GB RAM stock (expandable to 32 GB) and four bays, it handles 8-12 cameras without strain and has headroom for additional workloads alongside surveillance. For businesses where the NAS also handles file sharing or backup, the DS925+ handles both without compromise.

QNAP TS-664 (from $1,549 at PLE Computers, Scorptec) adds two more bays and an Intel Core i3 N305 processor with integrated GPU. Useful for hardware-accelerated transcoding of multiple live streams. Six bays provides substantial storage expansion potential. The TS-664 suits setups with 12-16 cameras that need regular remote viewing access across multiple simultaneous users.

Synology DS1525+ (from $1,285 at Mwave, Scorptec) is a 5-bay option on an AMD Ryzen R1600 that bridges the gap between 4-bay and 8-bay in terms of storage capacity. Five bays at RAID 5 gives more usable space than a 4-bay equivalent. Useful when running high-resolution cameras or extended retention periods.

Remote Access and Australian NBN Considerations

Remote access to your surveillance NAS. Checking live cameras from your phone, reviewing footage after an incident. Requires the NAS to be reachable from outside your home or office network. This is where Australian NBN connections introduce some friction.

The typical NBN 100 plan provides around 56 Mbps upload in practice. For a 4-camera setup with cameras streaming at 2 Mbps each (H.265), you need 8 Mbps of upstream bandwidth for live remote view. Comfortably within NBN 100 limits. However, scaling to 16 cameras all streaming simultaneously would push 32 Mbps upstream, which is near the ceiling of NBN 100 upload. NBN 250 or NBN 1000 plans provide significantly more headroom for multi-camera remote access.

CGNAT is a real problem for some NBN connections. If your ISP places you behind Carrier-Grade NAT (common on some FTTP, FTTC, and wireless NBN connections), your NAS will not be directly reachable from the internet via port forwarding. Synology's QuickConnect and QNAP's myQNAPcloud relay services bypass CGNAT by routing connections through vendor relay servers. This works but adds latency and caps bandwidth compared to a direct connection. If remote surveillance access is important, confirm with your ISP whether you have a public IP address or are behind CGNAT. A static IP add-on (where available) resolves the issue cleanly.

For businesses with static IPs and NBN Business plans, direct DDNS-based access or VPN tunnels are the preferred approach. More secure and lower latency than vendor relay services.

Where to Buy in Australia

NAS surveillance setups involve meaningful spend. NAS unit, drives, cameras, PoE switch. And the retailer relationship matters more than it does for commodity purchases. If a NAS fails mid-recording with 8 weeks of footage inside, you want a retailer who can move quickly on a replacement.

For NAS hardware, Scorptec, PLE Computers, and Mwave are the primary retailers with genuine stock depth and specialist-adjacent staff. Pricing across these stores is remarkably uniform. Most retailers operate on 3-5% NAS margin, leaving little room for price variation. The meaningful differences are stock depth, pre-sales knowledge, and post-sales support.

BlueChip holds the deepest NAS stock in Australia, supplying both Synology and QNAP to most major retailers. When a model shows as out of stock at retail, expect a 2-3 week lead time for air freight restocking from Taiwan. Business and enterprise models (rackmount, high-bay units) are rarely held in retailer stock even when listed as available. Expect 2-3 days for the retailer to process through distributor dropship before an order ships.

Amazon AU has become a real option for NAS in 2026 and sometimes prices 10-20% below local retailers. For surveillance setups specifically, this is a calculated risk: if a NAS fails with weeks of irreplaceable security footage inside, Amazon's support model. No pre-sales advice, no advanced replacement, no technical escalation path. Is a meaningful liability. Buy from a specialist for a surveillance deployment.

For business purchases, always request a formal quote rather than buying at listed retail price. Resellers can request pricing support from distributors and vendors, and discounts that never appear on the website are routinely available for quoted deals. Particularly for multi-unit or project-scale orders.

Step-by-Step: Setting Up NAS Surveillance

Once you have your NAS, drives, cameras, and PoE switch, the setup process follows a consistent pattern regardless of brand:

1. Install drives and initialise the NAS. Follow the quick-start guide, create your storage pool and volume with your chosen RAID level. For surveillance, RAID 5 (3+ drives) or RAID 6 (4+ drives) provides a good balance of capacity and redundancy.
2. Install surveillance software. On Synology, open Package Centre and install Surveillance Station. On QNAP, install QVR Pro from App Center. On Asustor, install AiVideos from App Central.
3. Connect cameras to PoE switch. Wire cameras to your PoE switch, then connect the switch to your network. Cameras should receive an IP address from your router's DHCP server.
4. Add cameras in surveillance app. Use the auto-discovery function to find cameras on your local network, or add them manually using IP address, RTSP stream URL, and credentials. Select the appropriate camera driver from the compatibility list for full feature access.
5. Configure recording schedules. Set continuous recording or motion-triggered schedules per camera. Define the recording destination (the volume you created in step 1) and set retention duration. The app will warn you if storage is insufficient for your settings.
6. Set up motion detection zones. Define active motion areas per camera to reduce false trigger notifications and focus recording resources on relevant activity.
7. Configure remote access. Enable QuickConnect (Synology) or myQNAPcloud (QNAP) for relay-based remote access, or set up port forwarding/VPN for direct access. Test remote view from mobile data before considering setup complete.
8. Test and verify retention. After 24-48 hours of recording, verify footage is saving correctly, check the storage utilisation rate, and confirm the estimated retention period displayed in the app matches your requirements.

Do I need a separate NVR if I have a NAS?

No. A NAS running Synology Surveillance Station, QNAP QVR Pro, or Asustor AiVideos replaces a dedicated NVR entirely. You get IP camera recording, live view, playback, and event alerts. Plus all the other NAS functions (file storage, backup, media) on the same hardware. A dedicated NVR only makes sense if you specifically want a locked-down single-purpose appliance, or if an integrator prefers a closed appliance for a commercial install.

How many cameras can a Synology DS425+ handle?

The DS425+ includes two free Surveillance Station licences. Additional cameras require paid licence packs (approximately $75-90 AUD per camera at current pricing). Hardware-wise, the DS425+ on its Intel Celeron J4125 processor handles 8-12 simultaneous 1080p streams for recording without strain. Live transcoding for multiple simultaneous remote viewers is more demanding. If you regularly view 6+ cameras remotely at the same time, consider upgrading to the DS925+ with its AMD Ryzen R1600 for more CPU headroom.

What hard drives should I use for NAS surveillance recording?

Use NAS-grade drives rated for 24/7 operation. Seagate IronWolf, Seagate IronWolf Pro, WD Red Plus, or WD Red Pro. Seagate SkyHawk drives are specifically optimised for surveillance workloads and include AllFrame technology for smoother multi-stream recording. Do not use desktop (Barracuda, WD Blue) or gaming drives. They are rated for 8-hour daily workloads and will fail prematurely under continuous surveillance recording. Note that NAS-grade drive prices have increased significantly from 2025 levels; current 4TB NAS drives are consistently above $200 in Australia.

My NAS is behind NBN CGNAT. Can I still access my cameras remotely?

Yes, but with caveats. Both Synology QuickConnect and QNAP myQNAPcloud relay services route your remote connection through vendor relay servers, bypassing CGNAT without requiring port forwarding or a public IP. This works reliably for mobile viewing and playback but adds latency compared to a direct connection, and bandwidth through relay servers is typically capped. For high-quality live view of multiple cameras over a relay, performance may be limited. The clean solution is to request a static IP or public IP option from your ISP. Many NBN providers offer this as a paid add-on, and it enables direct port forwarding or VPN-based access with significantly better performance.

Can I mix cameras from different brands in one NAS surveillance setup?

Yes. Synology Surveillance Station and QNAP QVR Pro both support ONVIF, which means any ONVIF-compatible camera. Regardless of brand. Will connect. Cameras listed on Synology's or QNAP's official compatibility list will offer deeper feature integration (PTZ control, motion zone sync, audio), while generic ONVIF cameras will provide basic stream recording. It's entirely practical to run Hikvision cameras alongside Reolink cameras, or to add a new brand without replacing your existing setup.

Is wireless (Wi-Fi) camera recording reliable enough for home surveillance on a NAS?

For casual home monitoring, wireless cameras are acceptable. For security-critical applications, they are not recommended. Wi-Fi cameras are vulnerable to signal drops, interference from neighbouring networks, and deliberate jamming. A real consideration for theft deterrence scenarios. Wired PoE cameras connected via a PoE switch are significantly more reliable and the preferred approach for any surveillance setup where continuous uninterrupted recording matters. If cabling is genuinely not possible, Wi-Fi cameras are a workable fallback, but set expectations accordingly regarding recording gaps.

What RAID level should I use for a surveillance NAS?

RAID 5 is the standard choice for 4-bay surveillance NAS setups. It provides one-drive fault tolerance while maximising usable capacity (three drives of storage from four physical drives). RAID 6 offers two-drive fault tolerance and suits 6-bay and larger units where the cost of a second drive failure is higher. Avoid RAID 0 (no redundancy) and RAID 1 (mirroring. Wastes capacity) for surveillance unless you have a specific reason. Remember: RAID is not a backup. If your NAS is storing surveillance footage you may need for insurance or legal purposes, consider a second storage copy or cloud backup for critical segments.
