NAS Surveillance Camera Compatibility Guide Australia

Not every IP camera works with every NAS surveillance platform, and the wrong combination can mean lost footage, missing features, or a camera that simply refuses to connect. Synology Surveillance Station, QNAP QVR Pro, and Asustor Surveillance Center each maintain their own compatibility lists, and those lists do not always agree. Popular camera brands in Australia. Hikvision, Dahua, Reolink, Ubiquiti, and Axis. All have different levels of support across the three platforms. Before buying cameras or a NAS, you need to check compatibility, understand what ONVIF actually guarantees (and what it does not), and factor in the real costs of camera licenses, storage, PoE switching, and Australian privacy obligations.

NAS Surveillance Platforms Compared

The three major NAS surveillance platforms available in Australia are Synology Surveillance Station, QNAP QVR Pro, and Asustor Surveillance Center. Each takes a different approach to camera compatibility, licensing, and feature depth. Understanding these differences is essential before committing to a platform, because switching later means replacing either your cameras or your NAS.

Synology Surveillance Station

It supports over 8,800 camera models from more than 140 brands, giving it a larger advertised camera-model count than QNAP's current list. The software itself is polished, with a clean web interface, reliable mobile apps (DS Cam for iOS and Android), and solid motion detection capabilities. Surveillance Station also supports AI-powered analytics on DVA-series appliances, including person detection, vehicle recognition, and intrusion detection. Though these features require specific (and expensive) hardware.

The trade-off is licensing. Every Synology NAS includes just 2 free camera licenses. Additional licenses cost approximately $99 per camera or $349 for a 4-pack at Australian retailers like Mwave. For a home system running 6 cameras, that is $349 in license fees on top of the NAS hardware. For a business running 16 cameras, license costs alone exceed $1,100. This licensing model makes Synology the most expensive platform to scale, but many users accept the cost because the software is genuinely the most reliable and user-friendly option available. For a detailed NAS hardware comparison, see our best NAS for surveillance guide.

QNAP QVR Pro

QNAP QVR Pro takes a fundamentally different approach to licensing. QVR Pro includes 8 camera channels, but without an Unlimited Playback or QVR Pro Gold licence, playback through QVR Pro Client is limited to the latest 14 days; older recordings remain accessible through File Station. Four times what Synology offers at no extra cost. Additional channels are available at lower per-camera pricing than Synology. For deployments of 8 or more cameras, the total cost difference between QNAP and Synology can be substantial. QVR Pro supports over 8,000 camera models and has solid ONVIF Profile S and T support.

QVR Pro runs as a containerised application on QNAP NAS devices, which means it operates in an isolated environment that does not interfere with other NAS functions. The software is capable but has a steeper learning curve than Synology. The web interface is functional rather than elegant. Mobile access via the QVR Pro Client app works, though it is not as refined as Synology's DS Cam. QNAP also offers QVR Elite with 2 included camera channels, while QVR Smart Search provides AI-based event search through the QVR AI Pack.

Asustor Surveillance Center

Asustor Surveillance Center is the least mature of the three platforms but includes 4 free camera licenses on most models. A middle ground between Synology's 2 and QNAP's 8. The software supports ONVIF-compliant cameras and maintains a compatibility list, though it is significantly smaller than Synology's or QNAP's. Asustor Surveillance Center is adequate for basic recording and remote viewing but lacks the advanced analytics, AI features, and depth of integration offered by the other two platforms. For simple home surveillance with 4 or fewer cameras, it does the job. For anything more demanding, Synology or QNAP are stronger choices.

ONVIF: What It Guarantees and What It Does Not

ONVIF (Open Network Video Interface Forum) is the industry standard protocol for IP camera interoperability. When a camera is ONVIF-compliant, it means it follows a standardised communication protocol that any ONVIF-compatible recording system should be able to use. Products registered as conformant to the same ONVIF profile and applicable firmware/software versions should interoperate for the profile's common features, but optional functions and implementation quality can still affect results. In practice, the reality is more nuanced.

ONVIF has multiple profiles. Profile S covers basic video streaming. Connecting a camera, receiving a live feed, and recording. Profile T adds support for H.265 video encoding, imaging settings, motion detection events, and metadata streaming. Most modern IP cameras support Profile S at minimum. Higher-end cameras support both S and T. If your camera and NAS both support Profile T, you get better integration with event-based recording and motion detection triggers.

There is also the RTSP (Real Time Streaming Protocol) fallback. Almost all IP cameras support RTSP, which allows you to manually add a camera to any NAS surveillance platform using its RTSP stream URL. RTSP can provide basic media streaming when both the camera and NAS platform support the stream's URL, authentication, transport, and codec, but it is not a universal compatibility guarantee. The trade-off is that RTSP connections typically require manual configuration (finding the correct stream URL format for your camera brand) and may not support event-triggered recording or motion detection at the NAS level.

Camera Brand Compatibility in Australia

The cameras most commonly sold in Australia for NAS-based surveillance fall into five major brands. Each has different strengths and different compatibility profiles across the three NAS platforms.

Hikvision

Hikvision is the world's largest surveillance camera manufacturer and has extensive compatibility across all three NAS platforms. Synology, QNAP, and Asustor all list hundreds of Hikvision models on their compatibility lists. Hikvision cameras support ONVIF Profile S and T, and their RTSP URL structure is well-documented. In Australia, Hikvision cameras are widely available through security installers and online retailers. The value series offers excellent image quality at competitive prices, and the ColorVu range with full-colour night vision has become popular for residential installations. Hikvision cameras are among the safest choices for NAS compatibility. A compatibility-list entry identifies the integrated functions and required firmware or Device Pack version, but it is not a guarantee of reliability in every deployment.

Dahua

Dahua is the second-largest surveillance camera manufacturer globally and shares Hikvision's broad NAS platform support. Synology and QNAP both list extensive Dahua model support. Dahua cameras are ONVIF-compliant and support standard RTSP streams. In Australia, Dahua is commonly found through security installers and trade-focused retailers. Their Imou consumer brand is also available through Amazon AU and general electronics retailers. Dahua cameras work reliably with NAS platforms and are a solid choice for users who want professional-grade hardware at a slightly lower price point than equivalent Hikvision models.

Reolink

, but its official NAS compatibility status is mixed. Multiple Reolink cameras are officially listed by Synology, including the RLC-810A, and QNAP also lists selected Reolink models; support remains model- and firmware-specific. The reason is that Reolink has historically used a proprietary protocol alongside ONVIF, and some models had inconsistent ONVIF implementation in earlier firmware versions. More recent Reolink firmware has improved ONVIF compliance significantly.

In practice, most current Reolink cameras (RLC-810A, RLC-820A, RLC-1212A, CX series, TrackMix, Duo 3 PoE) work with Synology Surveillance Station and QNAP QVR Pro via ONVIF or RTSP. The key is to ensure ONVIF is enabled in the Reolink camera settings (it is often disabled by default) and that the camera firmware is up to date. Reolink cameras offer exceptional value in Australia. A 4K PoE camera for under $150. And their direct-to-consumer model through Amazon AU keeps prices low. The trade-off is the lack of official vendor support on NAS platforms, which means troubleshooting falls on you if something does not connect properly.

Ubiquiti (UniFi Protect)

Ubiquiti UniFi cameras are popular in Australia, particularly among users already running UniFi networking equipment. However, UniFi cameras are not compatible with NAS surveillance platforms. UniFi Protect cameras use a proprietary protocol and can only record to UniFi Protect hardware. UniFi cameras require a console that supports UniFi Protect, such as a Cloud Gateway Max or UNVR; Cloud Gateway Ultra and UNAS Pro do not run Protect. UniFi cameras are managed through UniFi Protect rather than direct ONVIF integration, but Protect can expose outgoing RTSP/RTSPS streams that a compatible third-party recorder may ingest.

If you are already invested in UniFi Protect, your surveillance storage must be UniFi hardware. If you want to use a NAS for surveillance storage, you need to choose cameras from a different brand. Some users run both systems in parallel. UniFi cameras on UniFi hardware for primary coverage and a separate set of ONVIF cameras on a NAS for additional angles or backup recording. But this adds cost and complexity.

Axis Communications

Axis is the premium end of the IP camera market and has excellent NAS compatibility. Axis cameras are fully ONVIF-compliant (the company was a founding member of the ONVIF standard) and are extensively listed on both Synology's and QNAP's compatibility lists. Axis cameras offer superior build quality, excellent low-light performance, and advanced on-camera analytics. The downside is price. In Australia, Axis cameras are sold through professional security integrators and specialist distributors. They are the right choice for commercial installations where image quality and reliability justify the premium, but they are overkill for most residential setups.

Storage Calculations: How Much Space Per Camera Per Day

Storage is the most underestimated cost in a NAS surveillance system. Cameras generate a continuous stream of data, and the numbers add up fast. How much storage you need depends on three factors: resolution, frame rate, and whether you record continuously or only on motion. For a full breakdown with a storage calculator, see How Much Storage Does a CCTV System Need?

Daily storage should be calculated from each camera's configured or observed bitrate and recording time; resolution, frame rate, codec, compression settings, and scene activity all affect that bitrate. H.265 can reduce bitrate and storage compared with H.264 at a comparable quality target, but the saving varies with the camera, encoder settings, and scene., which is why H.265-capable cameras and NAS platforms are worth prioritising.

Motion-triggered recording can reduce storage, but the reduction depends on how long events keep each camera recording, including pre-event and post-event buffers; estimate it from observed activity or a stated duty-cycle assumption. For most residential setups, motion-triggered recording is the practical choice. Continuous recording is standard for commercial and high-security installations where you cannot afford gaps.

PoE Switch Requirements

Power over Ethernet (PoE) is the standard method for powering IP cameras. A PoE switch delivers both data and power through a single Ethernet cable, eliminating the need for separate power adapters at each camera location. For any NAS-based surveillance system with more than one or two cameras, a PoE switch is effectively mandatory.

Most IP cameras in Australia use the IEEE 802.3af (PoE) standard, which delivers up to 15.4W per port. This is sufficient for standard fixed cameras. PTZ cameras and cameras with built-in heaters (for extreme environments) may require IEEE 802.3at (PoE+), delivering up to 30W per port. Check your camera's power requirements before selecting a switch.

When sizing a PoE switch, pay attention to the total PoE power budget, not just the number of ports. An 8-port PoE switch might have a 60W, 120W, or 150W total budget. If each of your 8 cameras draws 10W, you need at least 80W total. A 60W switch will not power all of them simultaneously. A reliable 8-port PoE switch with adequate power budget costs $150-350 in Australia. Unmanaged PoE switches from TP-Link, Netgear, and Hikvision are common choices for home setups. For more advanced requirements, QNAP's QSW-series switches offer PoE options with 2.5GbE and 10GbE uplinks, pairing naturally with a QNAP NAS.

Motion Detection vs Continuous Recording

The choice between motion-triggered and continuous recording affects storage consumption, NAS workload, and how useful your footage is when you actually need it. Both approaches have clear trade-offs.

Motion-Triggered Recording

Motion detection recording only saves footage when the camera detects movement. This dramatically reduces storage requirements. Typically 30-50% of what continuous recording would consume. It also reduces write wear on your hard drives and makes reviewing footage faster because you only see clips where something happened. Most NAS surveillance platforms support both camera-side motion detection (the camera detects motion and tells the NAS to start recording) and NAS-side motion detection (the NAS analyses the incoming stream and decides when to record).

Camera-side detection is generally preferred because it is more responsive and reduces NAS CPU load. Higher-end cameras from Hikvision, Dahua, and Axis include smart motion detection that can distinguish between people, vehicles, and animals. Reducing false triggers from swaying trees or passing clouds. Reolink cameras also offer on-camera person/vehicle detection on most current models. The camera may perform person, vehicle, or animal classification locally, but NAS-triggered recording and alerts require the NAS to receive compatible event metadata; an RTSP stream alone does not guarantee that integration.

Continuous Recording

Continuous recording captures everything, 24/7, regardless of activity. This is the standard for commercial and high-security environments where any gap in footage could be a liability. The obvious downside is storage. Continuous recording usually requires more storage than event-only recording, but the difference depends on the event-recording duty cycle and pre/post-event settings. It also places a heavier sustained load on the NAS and drives. If you choose continuous recording, use surveillance-rated drives (Seagate SkyHawk or WD Purple) that are designed for constant sequential writes, and ensure your NAS has adequate cooling to handle the thermal load of 24/7 drive activity.

A practical compromise used by many Australian home setups: configure continuous recording at a lower sub-stream quality (e.g., 720p at 5 fps) alongside motion-triggered recording at full resolution (4K at 15 fps). This gives you a complete timeline of low-resolution footage for context and full-quality clips of actual events. Both Synology Surveillance Station and QNAP QVR Pro support dual-stream recording. Check that your camera supports a main stream and a sub-stream, which most do.

Remote Viewing: NBN Upload Speeds and CGNAT

Viewing your surveillance footage remotely. From your phone at work or while travelling. Is one of the main advantages of a NAS-based system. But remote access in Australia comes with two specific challenges that trip up many first-time buyers: limited NBN upload speeds and CGNAT. For a deeper guide on setting up reliable remote access, see our NAS remote access and VPN guide.

NBN Upload Speed Reality

Remote surveillance viewing relies entirely on your home internet upload speed, not download. Available upload speed depends on the current retail plan and NBN access technology. Eligible FTTP/HFC Home Fast services were uplifted from wholesale 100/20 to 500/50 in September 2025, while other technologies and plans may provide lower rates. A single 1080p stream viewed remotely requires approximately 2-4 Mbps. A 4K stream can demand 8-15 Mbps. This means you can comfortably view one or two 1080p camera feeds remotely on a typical NBN plan, but attempting to view multiple 4K streams simultaneously will overwhelm your upload bandwidth.

Both Synology Surveillance Station and QNAP QVR Pro mitigate this by transcoding or down-scaling the stream for remote viewing. When you open DS Cam or QVR Pro Client on your phone, the NAS sends a lower-quality stream that fits within your available upload bandwidth. The full-quality recording continues on the NAS drives. Remote transcoding only affects what you see live. If you upgrade to an NBN 100/40 or NBN 250/25 plan, the additional upload headroom allows higher-quality remote viewing of multiple cameras.

CGNAT. The Hidden Blocker

CGNAT (Carrier-Grade NAT) is a technique used by some Australian ISPs. Particularly those on NBN fixed wireless, satellite, and some fibre-to-the-node connections. To share a single public IP address among multiple customers. If your ISP uses CGNAT, standard port forwarding and direct VPN connections to your NAS will not work. Your NAS is effectively hidden behind a layer of NAT that you do not control.

The workarounds for CGNAT are: (1) Use the NAS vendor's relay service. Synology QuickConnect or QNAP myQNAPcloud. These route your connection through the vendor's cloud servers, bypassing CGNAT entirely. The trade-off is added latency and potential throughput limits. (2) Use a VPN service like Tailscale or ZeroTier, which establish outbound tunnels from your NAS that CGNAT cannot block. (3) Contact your ISP and request a static public IP or ask to be removed from CGNAT. Some providers (Aussie Broadband, Superloop) will do this on request, while others will not. Before investing in a NAS surveillance system, check whether your ISP uses CGNAT by looking up your WAN IP on your router and comparing it to a "what is my IP" website. If they differ, CGNAT is one possibility, but first rule out an upstream router, VPN, or other local double-NAT configuration and confirm with your ISP.

Australian Privacy Laws for CCTV

Installing surveillance cameras in Australia is legal, but there are federal and state/territory privacy laws that dictate what you can and cannot do. Getting this wrong can result in complaints to the Office of the Australian Information Commissioner (OAIC) or state privacy bodies, and in serious cases, civil or criminal penalties. These laws apply whether your footage is stored on a NAS, in the cloud, or on a standalone NVR.

Residential CCTV Rules

For home installations, the general principles across Australian states and territories are: (1) Whether video may be recorded without consent depends on the state or territory, what activity is captured, where the camera is installed, and the surrounding circumstances. (2) Your cameras should not capture areas beyond your property boundary where there is an expectation of privacy. A neighbour's backyard, windows, or private outdoor living areas. Do not assume that recording a public-facing area is automatically lawful; check the applicable state or territory rules and, for covered organisations, the Privacy Act obligations. (3) Audio recording is heavily restricted. In most states, recording a private conversation without the consent of at least one party (and in some states, all parties) is illegal under surveillance devices legislation. If your cameras have microphones, understand your state's rules before enabling audio recording. Most NAS users disable audio on outdoor cameras to avoid this issue.

State and territory laws vary. In New South Wales, the Surveillance Devices Act 2007 regulates listening devices used for private conversations and restricts optical-surveillance-device installation or use where it involves unauthorised entry onto premises or interference with a vehicle or object. In Victoria, the Surveillance Devices Act 1999 has similar provisions. Queensland is generally more permissive for video-only recording on your own property but restricts audio. Western Australia, South Australia, Tasmania, the ACT, and the Northern Territory each have their own surveillance devices legislation with varying thresholds. The safest approach for residential CCTV is to keep cameras pointed at your own property and public-facing areas, disable audio recording unless you are certain it is legal in your state, and place visible signage indicating that CCTV is in operation.

Business and Commercial CCTV Obligations

Organisations with annual turnover of more than $3 million are generally subject to the Privacy Act 1988 and APPs; some businesses at or below that threshold are also covered because of their activities or because they have opted in. This means businesses must notify individuals that surveillance is occurring (typically through signage), have a legitimate purpose for the surveillance (security, safety, loss prevention), securely store footage and restrict access, and destroy or de-identify footage when it is no longer needed, subject to applicable legal exceptions; a documented retention policy is a practical way to manage that obligation. Do not keep footage indefinitely without reason. A NAS with proper user access controls and automated retention policies (both Synology Surveillance Station and QNAP QVR Pro support configurable retention periods) helps meet these obligations. For businesses that handle sensitive personal information or operate in regulated industries, consult a privacy professional to ensure your CCTV setup complies with applicable legislation.

Protecting Your NAS and Footage

A surveillance NAS stores sensitive footage that may be needed as evidence. Protecting both the NAS hardware and the data on it is essential. A few specific considerations apply to surveillance setups that go beyond standard NAS security practices. For a comprehensive guide to NAS security, see our NAS security and ransomware protection guide.

Use a UPS (uninterruptible power supply). A surveillance NAS runs 24/7 and is vulnerable to power outages, surges, and brownouts. A UPS keeps the NAS running during short outages and triggers a clean shutdown during extended ones, protecting your drives and ensuring active recordings are not corrupted. Both Synology and QNAP support UPS integration via USB. See our UPS for NAS guide for Australian-specific recommendations.

Restrict NAS access. Do not expose your surveillance NAS directly to the internet. Use VPN access or the vendor's relay service (QuickConnect, myQNAPcloud) for remote viewing. Disable UPnP on your router. Use strong, unique passwords and enable two-factor authentication on the NAS admin account. The last thing you want is an intruder accessing your surveillance system to check camera blind spots or delete footage before a break-in.

Consider physical security. A NAS sitting on a desk in a home office is easy to steal. Mount it in a locked cabinet, place it in a concealed location, or at minimum ensure it is not in the same room as a camera that a burglar might spot and trace back to the recorder. Some users install the NAS in the roof space or a locked garage cabinet. If the NAS is stolen, the footage goes with it. Unless you have enabled offsite replication (Synology's Hyper Backup or QNAP's HBS 3) to copy critical clips to a cloud service or a second NAS at another location.

How to Check Camera Compatibility Before Buying

Before purchasing cameras for your NAS surveillance system, follow these steps to avoid compatibility headaches:

1. Check the official compatibility list. Synology publishes their list at synology.com/compatibility/surveillance-station. QNAP maintains theirs at qnap.com/compatibility. Search for the specific camera model number. Not just the brand. A camera brand being listed does not mean every model from that brand is supported.

2. Confirm ONVIF profile support. If the camera is not on the NAS vendor's list, verify that its exact model and firmware are registered in ONVIF's conformant-product database and prefer Profile T, which ONVIF recommends as the replacement for Profile S. This gives you the best chance of the camera working via ONVIF auto-discovery, even without specific vendor integration.

3. Find the RTSP URL format. As a fallback, identify the camera's RTSP stream URL format. This is usually documented in the camera's manual or on community forums (ispy, ispyconnect.com maintains a large database of RTSP URLs by camera model). Adding a camera via RTSP ensures basic recording compatibility with any NAS platform.

4. Check firmware requirements. Some cameras require a specific firmware version for ONVIF to function correctly. Reolink cameras, in particular, have improved ONVIF compliance significantly across firmware updates. Always update camera firmware before attempting NAS integration.

5. Test before committing. If possible, buy one camera first and test it with your NAS before purchasing the rest. Verify that live viewing, recording, motion detection, and remote playback all work as expected. A single $150 test camera is cheaper than discovering compatibility issues after installing 8 cameras on your roof.

Camera firmware decides more than ONVIF compatibility. Australia's smart device security rules require in-scope connected products to publish how long they will receive security updates, which is worth checking before committing to one camera brand across a whole property.

Can I use Reolink cameras with a Synology NAS?

Yes, most current Reolink cameras work with Synology Surveillance Station via ONVIF or RTSP, and several models, including the RLC-810A, are on Synology's official compatibility list. You need to enable ONVIF in the Reolink camera settings (it is disabled by default on most models), ensure the camera firmware is up to date, and add the camera in Surveillance Station using ONVIF auto-discovery or the manual RTSP stream URL. Models like the RLC-810A, RLC-820A, and RLC-1212A are widely used with Synology by Australian NAS users. The trade-off is that without official support, you may not get features like camera-side motion detection events passed to the NAS. You may need to rely on NAS-side motion detection instead.

Do UniFi cameras work with Synology or QNAP?

No. Ubiquiti UniFi Protect cameras use a proprietary protocol and can only record to UniFi Protect hardware (Cloud Gateway Ultra, Cloud Gateway Max, UNVR, or UNAS devices). UniFi cameras do not offer direct ONVIF integration, but a Protect console can provide outgoing RTSP/RTSPS streams. You cannot connect UniFi cameras to Synology Surveillance Station, QNAP QVR Pro, or any third-party NVR. If you want NAS-based surveillance, you need to use cameras from a different brand such as Hikvision, Dahua, or Reolink.

How many cameras can a NAS handle before performance suffers?

It depends on the NAS hardware, camera resolution, and recording mode. A 2-bay Synology DS225+ is officially rated for up to 25 1080p H.264/H.265 camera channels under Synology's test conditions, although practical capacity depends on camera settings, drives, configuration, and other workloads. A 4-bay Synology DS425+ or QNAP TS-464 handles 8-12 cameras at 1080p or 4-8 at 4K. Above 12-16 cameras, look at higher-end models with more powerful CPUs and RAM, or dedicated NVR appliances. The NAS vendor's camera calculator tools provide model-specific guidance. Remember that running other workloads on the NAS alongside surveillance (file sharing, Docker containers, Plex) reduces the headroom available for cameras.

Is it legal to record audio on surveillance cameras in Australia?

Audio recording is heavily restricted in Australia. Most states and territories have surveillance devices legislation that prohibits recording private conversations without consent. In NSW and Victoria, recording a private conversation without consent from at least one party is a criminal offence. Some states require all-party consent. The safest approach for residential CCTV is to disable microphones on outdoor cameras entirely. If you have a legitimate need for audio recording (e.g., a business intercom system), check your specific state or territory legislation and consider seeking legal advice. Video-only recording on your own property is generally permissible across all jurisdictions.

What is ONVIF and do I need it for my NAS cameras?

ONVIF (Open Network Video Interface Forum) is a standardised protocol that allows IP cameras to communicate with NVRs and NAS surveillance platforms regardless of brand. If a camera supports ONVIF, it should be able to connect to any ONVIF-compatible recording system. You do not strictly need ONVIF. Cameras on the NAS vendor's official compatibility list may use the vendor's native integration, which often provides better feature support. But ONVIF is valuable as a compatibility guarantee for cameras not on the official list, and RTSP (which most ONVIF cameras also support) serves as a universal fallback. For the broadest compatibility, choose cameras that support ONVIF Profile S and T.

How much hard drive space do I need for a 4-camera surveillance system?

For a typical 4-camera home setup recording at 1080p with motion detection and 30-day retention, expect to need approximately 720 GB to 1.5 TB of storage. At 4K resolution with motion detection, that increases to approximately 2-4 TB. Continuous recording roughly doubles these figures. A 2-bay NAS with two 4 TB drives in RAID 1 (mirrored, 4 TB usable) comfortably covers most 4-camera home systems. For 4K continuous recording or longer retention periods, step up to a 4-bay NAS with larger drives. Both Synology and QNAP provide storage calculator tools on their websites to help estimate your specific requirements.

Will CGNAT stop me from viewing my NAS cameras remotely?

CGNAT blocks direct inbound connections to your NAS, which means standard port forwarding and direct VPN connections will not work. However, both Synology (QuickConnect) and QNAP (myQNAPcloud) provide relay services that work around CGNAT by routing your connection through the vendor's servers. The trade-off is slightly higher latency and potential throughput limitations. Alternatively, you can use a VPN overlay like Tailscale or ZeroTier, which establishes outbound connections that bypass CGNAT. You can also contact your ISP. Providers like Aussie Broadband and Superloop will often remove CGNAT on request or provide a static IP. Check whether your ISP uses CGNAT before investing in a NAS surveillance system.

Should I use Synology or QNAP for a surveillance NAS?

Synology Surveillance Station is more polished, easier to use, and has the broadest official camera compatibility list. It suits users who value simplicity and software quality. QNAP QVR Pro includes 8 free camera licenses versus Synology's 2, making it significantly cheaper for systems with 4 or more cameras. For a home with 2-4 cameras where the NAS also serves as general file storage, Synology is the easier choice. For larger setups or budget-conscious buyers who want to avoid license costs, QNAP delivers better value. Both platforms handle recording, remote viewing, and motion detection well. The deciding factor is usually license cost vs software polish. See our full comparison in the best NAS for surveillance guide.
