A NAS-based surveillance setup offers something most dedicated NVRs and cloud camera systems do not: genuine flexibility. The same device that records your cameras also stores your backups, serves your Plex library, and hosts a Docker container for Home Assistant. When a dedicated NVR sits in your closet doing only one job, a NAS earns its space by handling many.
Both Synology and QNAP have invested heavily in their surveillance platforms. Synology Surveillance Station is mature, well-documented, and widely regarded as the easier of the two to configure. QNAP QVR Pro is more feature-rich out of the box and includes 8 free camera channels compared to Synology's 2. The right choice depends on how many cameras you are running and how much you value software polish versus raw channel count.

NAS as NVR vs Dedicated NVR: Which Makes More Sense?
A dedicated NVR is purpose-built for one job. It is typically cheaper than a comparable NAS, ships with a hard drive included, has a built-in PoE switch for cameras, and requires no software configuration beyond pointing it at cameras. If all you need is camera recording and playback, a dedicated NVR from Reolink, Hikvision, or Amcrest gets you there faster and cheaper.
A NAS-based NVR makes more sense in several situations. First, if you already own a NAS and want to add camera recording without buying another device. Second, if you need more flexibility than dedicated NVR software provides — advanced motion zones, integration with door sensors or smart home platforms, detailed event search, or AI-based object detection. Third, if you want a single device for cameras plus backups plus media, where the NAS cost is shared across multiple use cases rather than dedicated entirely to surveillance.
The break-even point is roughly a 4-camera setup. Below that, a $200 dedicated NVR may be more cost-effective. Above that, the additional camera license costs for a NAS-based system are offset by its multi-purpose value, and Synology Surveillance Station's superior software starts to pull ahead of the interface quality found on budget NVRs.
Synology Surveillance Station vs QNAP QVR Pro: Feature Comparison
Both platforms are mature products with similar core capabilities. The differences are in the details.
Camera licenses: Synology includes 2 free licenses with every NAS. QNAP QVR Pro includes 8 free camera channels — a meaningful advantage for 4-8 camera setups that would require $100-$300 in additional Synology licenses.
AI analytics: QNAP has invested more in AI analytics, including face detection, license plate recognition, and intrusion detection as add-on features. Synology's AI offerings are growing but remain more limited in the base product. For straightforward motion recording and event search, Synology's implementation is cleaner.
Motion zones and event search: Both platforms support customizable motion detection zones and event-based search. Synology's interface for configuring motion sensitivity and zones is generally considered more intuitive for first-time users.
Mobile viewing: Synology's DS cam app and QNAP's VMobile both support live view, event playback, and push notifications for motion events. Both work over the internet via their respective relay services without requiring manual port forwarding.
Smart home integration: Synology integrates with its own smart home platform and IFTTT. QNAP has broader third-party integration through QVR Pro's open API. If you are running Home Assistant, both can be integrated via ONVIF, but QNAP's more open architecture gives it an edge for advanced automation.
Camera License Costs: What Synology and QNAP Charge
License costs are one of the most important factors when planning a surveillance NAS setup, and they are easy to underestimate.
Synology: Every Synology NAS ships with 2 free camera licenses. Additional licenses are sold individually at approximately $50 each or in 4-license packs at a slight discount. An 8-camera setup requires 6 additional licenses at roughly $300. A 16-camera setup requires 14 additional licenses at roughly $700. These are one-time purchases — no annual renewal — but the upfront cost for large setups adds meaningfully to the total system price.
QNAP QVR Pro: QVR Pro includes 8 free camera channels on every compatible QNAP NAS. Additional channels are available through QVR Pro Gold subscription ($14.99/month for up to 8 additional channels) or through one-time add-on channel packs. For setups under 8 cameras, QNAP's included channel count eliminates the license cost entirely — a real advantage over Synology for small to mid-size deployments.
For a 4-camera home setup: QNAP costs $0 in additional licenses. Synology costs ~$100 for 2 additional licenses. For an 8-camera setup: QNAP still costs $0. Synology costs ~$300 for 6 additional licenses. At 16 cameras, both platforms require paid add-ons, and the cost difference narrows as QNAP's QVR Pro Gold subscription accumulates over time.
Storage Planning for Surveillance Footage
Surveillance storage is different from backup or media storage in one key way: it fills up continuously and requires a plan for what happens when it is full. Most NAS surveillance software handles this through automatic oldest-footage deletion — when storage hits a threshold, the oldest recorded segments are deleted to make room for new footage.
Estimating storage consumption per camera:
- 1080p at 15fps with H.264 compression: approximately 15-25GB per day per camera, depending on scene activity and compression settings.
- 1080p at 30fps: approximately 25-40GB per day per camera.
- 4K (2160p) at 15fps with H.265 compression: approximately 50-80GB per day per camera.
Retention period math for a 4-camera 1080p system at 20GB/day per camera:
- 4TB usable (2x4TB in RAID 1): approximately 50 days of retention
- 8TB usable (2x8TB in RAID 1): approximately 100 days of retention
- 16TB usable (2x16TB in RAID 1 or 3x8TB in RAID 5): approximately 200 days of retention
This is why 4 bays matter for serious surveillance use. With only 2 bays, you are choosing between capacity (JBOD for maximum raw storage) and redundancy (RAID 1 for drive failure protection). A 4-bay NAS in RAID 5 lets you have both — meaningful capacity and one-drive-failure protection — which is the right configuration for long-term surveillance footage you cannot afford to lose.
IP Camera Compatibility and PoE Switch Pairing
IP camera compatibility is broad for both Synology and QNAP, but worth checking before purchasing cameras.
ONVIF compliance is the universal compatibility standard. Any camera that supports ONVIF Profile S (streaming) works with both Surveillance Station and QVR Pro, even if the specific camera model is not listed on the manufacturer's compatibility page. Most modern IP cameras from any brand support ONVIF.
Native integration provides more features. Cameras specifically listed on Synology's or QNAP's compatibility databases get full feature access: PTZ control through the NAS interface, lens adjustment, detailed event types, and sometimes two-way audio. Synology's compatibility list includes over 8,000 camera models. Reolink, Hikvision, Dahua, Amcrest, Axis, Bosch, and Hanwha all have strong native integration.
PoE switch pairing is the standard infrastructure for IP camera setups. A PoE switch delivers both data and power over a single Ethernet cable to each camera, eliminating the need for separate power adapters at every camera location. For an outdoor installation, a PoE switch connected to the NAS with a short uplink cable — and cameras running single Ethernet runs from that switch — is the cleanest possible installation. An 8-port PoE switch covers most home setups; a 16-port or managed PoE switch suits larger installations where VLAN isolation of camera traffic is desirable.
When building a NAS surveillance system from scratch, the typical complete setup involves: the NAS enclosure, NAS-rated hard drives, the surveillance software licenses, an unmanaged or managed PoE switch, IP cameras, and Ethernet cabling to camera locations. Running that Ethernet in-wall or along exterior surfaces before cameras are mounted saves significant effort compared to retrofitting later.
Frequently Asked Questions
How many cameras can a 2-bay NAS handle for surveillance?
2-4 cameras comfortably — storage is the main limit, not the processor. A 2-bay NAS with 2x8TB in JBOD (16TB total) can store approximately 200 days of continuous 1080p footage from 2 cameras at typical compression rates. Adding more cameras shortens the retention window proportionally. A 4-bay NAS becomes the right choice when you need more than 4 cameras or want long retention periods without sacrificing RAID redundancy.
Does Synology Surveillance Station require a subscription?
No — Synology Surveillance Station is free software included with every Synology NAS. Every Synology NAS ships with 2 free camera licenses. Additional camera licenses cost approximately $50 each as a one-time purchase — not an ongoing subscription. There is no monthly or annual fee for Surveillance Station itself, which makes the total cost of ownership much lower than cloud-based camera systems over a 3-5 year period.
What cameras work with Synology Surveillance Station?
Synology maintains a compatibility list of over 8,000 camera models from brands including Hikvision, Dahua, Reolink, Amcrest, Axis, Bosch, Hanwha, and many others. Any camera that supports the ONVIF protocol standard also works with Surveillance Station even if the specific model is not on Synology's compatibility list. For full feature support including PTZ control and advanced event types, use a camera that appears directly on the Synology compatibility database.
Can I view surveillance footage remotely from my NAS?
Yes — Synology's DS cam app for iOS and Android provides live view, event playback, and push notifications for motion alerts from anywhere with an internet connection. QNAP's VMobile app provides equivalent functionality for QVR Pro setups. Both platforms use their respective relay services (Synology QuickConnect and QNAP myQNAPcloud) to enable remote access without requiring manual port forwarding, though a direct connection is also possible for lower latency.
