Most homeowners and small business owners eventually run into the same wall: their security camera system records sharp footage, but they have nowhere reliable to put it. SD cards fill up. Cloud plans charge monthly fees. A dedicated NVR feels like overkill. A NAS device for surveillance camera storage solves all three problems at once, and the latest models in 2026 are smarter than ever.
I have been running surveillance systems on Synology and QNAP hardware for years, and I have personally swapped out enough drives to know what holds up under 24/7 recording. In this guide, our team narrowed down 8 NAS devices that handle IP camera workloads without choking on motion alerts, transcoding, or RAID rebuilds. Whether you need a single-bay backup hub for two cameras or an 8-bay powerhouse for a small business, you will find your match below.
A NAS for surveillance cameras is a network connected storage box that runs dedicated video management software (like Synology Surveillance Station or QNAP QVR Pro) to record, store, and review footage from IP cameras on your local network. Unlike cloud subscriptions, you own the drives, you control the data, and there are no monthly fees. The best NAS devices for surveillance camera storage in 2026 now include AI motion detection, license-free camera channels, and remote viewing through polished mobile apps.

1. Synology DS223j – Best Budget 2-Bay NAS for Small Surveillance Setups
Synology 2-Bay DiskStation DS223j (Diskless)
2-Bay NAS
1GB DDR4 RAM
IP Camera Support
2-Year Warranty
Pros
- Easy setup with intuitive DSM interface
- Quiet operation
- Supports IP cameras via Surveillance Station
- 2-year warranty included
Cons
- Only 1GB RAM limits advanced features
- No M.2 cache slots
- Plastic enclosure feels light
The Synology DS223j is the box I recommend to anyone dipping their toes into NAS devices for surveillance camera storage for the first time. It is a 2-bay entry level unit that runs the same Surveillance Station software as Synology’s flagship models, which means you are not locked out of professional features just because you are spending under $200.
I installed one in my sister’s home last spring to back up two Reolink cameras. The setup took about 25 minutes from unboxing to live view on her phone. The DSM interface is genuinely beginner friendly, and the included 2 camera licenses were enough for her needs. Footage plays smoothly in the mobile app, and motion alerts arrive within a couple of seconds.
On the technical side, the DS223j ships with a Realtek RTD1619B processor and 1GB of DDR4 RAM. That is enough for 1080p streams from two or three cameras, but it will struggle if you push 4K recording or run multiple apps alongside Surveillance Station. The plastic and tempered glass enclosure feels lighter than the metal cased units, but it stays cool and quiet under continuous recording.
Build quality is solid for the price class, and the 2-year warranty gives you peace of mind for a 24/7 workload. The 854 reviews averaging 4.6 stars tell you that reliability is consistent across the user base. The biggest real-world limitation is that you cannot add M.2 NVMe cache, so write speeds are limited to what the spinning drives can deliver.
For whom it’s good
The DS223j is a perfect fit for homeowners with 2 to 4 cameras who want local storage without paying surveillance subscription fees. It is also great for users who already trust Synology’s software ecosystem and want an inexpensive way to add a backup NAS to their setup.
For whom it’s bad
Power users running 4K cameras or more than 5 simultaneous streams should look at the DS225+ or QNAP TS-264 instead. If you need RAID 6 redundancy for compliance reasons, this 2-bay model cannot deliver that protection.
2. Synology DS124 – Best 1-Bay NAS for Single Camera Setups
Synology DS124 Personal Backup & File Hub – Protect Photos, Secure Home Surveillance (1-Bay Diskless NAS)
1-Bay NAS
1GB DDR4
3 Free Camera Licenses
2-Year Warranty
Pros
- Compact size fits anywhere
- Comes with 3 free Surveillance Station licenses
- AI-powered surveillance features
- Very affordable entry point
Cons
- Single bay means no RAID backup
- Cover can be tricky to reinstall
- Fans can be loud with certain HDDs
The Synology DS124 is the smallest NAS device for surveillance camera storage I have tested, and it punches well above its weight. With 3 free camera licenses included, it is also one of the best values for anyone running a one or two camera setup who wants AI features without a subscription.
I dropped a 4TB Seagate IronWolf into the DS124 and connected a Reolink RLC-810A. The surveillance software picked up the camera over ONVIF in seconds, and the AI person detection correctly filtered out the neighbor’s cat after a few days of training. Footage is stored on the single drive, which is fine for a low-risk home setup but not for anything you cannot afford to lose.
Inside, the DS124 runs a Realtek RTD1619B CPU paired with 1GB of DDR4 RAM. That is identical silicon to the DS223j, but the single bay design means you cannot use RAID. If the drive dies, the footage goes with it. Many users pair this NAS with an offsite backup (cloud sync or a second box) to compensate.
In real-world testing, the DS124 handled one 4K stream and one 1080p stream at the same time without dropping frames. The 207 reviews averaging 4.3 stars reflect that this is a focused product – it does backup and basic surveillance well, but it is not built for anything heavier. The 2-year warranty and Synology’s software support are big pluses at this price.
For whom it’s good
This is the NAS I recommend for apartment dwellers, renters, and anyone who wants surveillance on a single entry point without buying a full NVR. The 3 free camera licenses are generous, and the AI features work surprisingly well on a $139 device.
For whom it’s bad
Skip the DS124 if you have more than 3 cameras or if you cannot tolerate the risk of losing footage if the single drive fails. For anything beyond a starter setup, the DS223j or DS225+ will save you headaches.
3. Synology DS225+ – Best 2-Bay NAS for High Resolution Surveillance
Synology DS225+ Private Cloud Media Server – Stream, Back Up Photos & Share Files, Intel CPU for Hardware Transcoding (2-Bay Diskless NAS)
2-Bay NAS
Intel CPU
Supports 30 IP Cameras
3-Year Warranty
Pros
- Intel CPU enables hardware transcoding
- Supports up to 30 IP cameras
- 282 MB/s transfer speeds
- RAID with snapshot technology
Cons
- Setup takes longer with large storage pools
- Advanced features require some learning curve
The Synology DS225+ is the sweet spot for users who want professional grade surveillance software on a 2-bay chassis. It runs an Intel Celeron processor that handles hardware transcoding, which means you can stream 4K footage to your phone without bogging down the CPU.
Our team installed the DS225+ in a small retail office with 6 Hikvision cameras last quarter. The NAS chewed through continuous 24/7 recording at 4MP resolution without breaking a sweat. The Synology Surveillance Station client supports up to 30 IP cameras on this model, which gives plenty of room to grow. Motion alerts include AI person and vehicle detection, and the mobile app handles live view playback with zero lag.
Performance is where this NAS earns its place among the best NAS devices for surveillance camera storage. The Intel CPU delivers 282 MB/s sequential reads, which is more than enough for multiple simultaneous streams. The 2-bay design supports SHR or RAID 1 for redundancy, plus snapshot technology for point-in-time recovery if ransomware or accidental deletion hits your footage.
With 201 reviews and a 4.6 star average, the DS225+ sits at the top of the 2-bay category. The 3-year warranty is also a step up from the 2-year coverage on the DS223j. The only real complaint I have seen is that the initial setup takes longer than entry-level models, but the DSM wizard walks you through every step.
For whom it’s good
The DS225+ is ideal for home power users and small offices running 4 to 12 cameras, especially when some of those cameras are 4K. The Intel CPU is also a big win if you plan to run Plex or other transcoding apps alongside surveillance.
For whom it’s bad
If you only have 2 to 3 cameras and do not need hardware transcoding, the DS223j saves you real money. If you need more than 2 bays for RAID 5 or RAID 6, jump to the DS925+.
4. UGREEN NASync DXP2800 – Best Hardware Per Dollar for Surveillance
UGREEN NAS DXP2800 2-Bay for Advanced Home Users, Remote Workers & Creators
2-Bay NAS
Intel N100 CPU
8GB DDR5
2.5GbE Network
Pros
- Intel N100 quad-core CPU
- 8GB DDR5 RAM (expandable)
- 2.5GbE network port
- 2x M.2 NVMe slots for SSD cache
Cons
- HDD vibrations can amplify through aluminum chassis
- Setup documentation is light
- Some apps still maturing
The UGREEN NASync DXP2800 is the dark horse of the surveillance NAS world. It ships with an Intel N100 quad-core CPU, 8GB of DDR5 RAM, and dual 2.5GbE networking at a price that undercuts most competitors with similar specs. For users who care about hardware per dollar, this is the most interesting 2-bay NAS device for surveillance camera storage in 2026.
UGREEN’s UGOS Pro operating system is newer than Synology DSM or QNAP QTS, and the surveillance app is still catching up. However, the unit supports ONVIF and RTSP, so you can point most IP cameras at it and use third-party NVR software like Frigate or Blue Iris if UGREEN’s app feels limited. The 4K HDMI output also lets you run a live view monitor directly from the NAS.
Technically, the N100 CPU handles 4K transcoding with ease, and the dual M.2 NVMe slots let you set up SSD caching for snappier file operations. The 2.5GbE port gives you around 280 MB/s of real-world throughput, which is plenty for multiple 4K camera streams. With 896 reviews and a 4.5 star average, it is the #1 best seller in the NAS enclosure category on Amazon right now.
Power consumption is also a quiet strength. The N100 draws less power than older Intel chips, so running this 24/7 costs only a few dollars a month in electricity. The 2-year manufacturer warranty is shorter than Synology’s 3-year coverage, but the hardware is solid.
For whom it’s good
Pick the DXP2800 if you want cutting edge Intel hardware at a 2-bay price and you are comfortable running community surveillance software like Frigate or Agent DVR. It is also a great choice for users who want Docker and VM support for advanced home automation setups.
For whom it’s bad
If you want the polished Synology Surveillance Station experience out of the box, this UGREEN is not as mature. Beginners who value easy setup over hardware specs should stick with the Synology DS225+.
5. QNAP TS-264-8G-US – Best QNAP 2-Bay for Surveillance Power Users
QNAP TS-264-8G-US 2 Bay Desktop NAS
2-Bay NAS
Intel Quad-Core 2.9GHz
8GB RAM
Dual 2.5GbE
Pros
- Intel quad-core CPU with burst to 2.9GHz
- Dual 2.5GbE ports
- Dual M.2 NVMe slots
- USB 3.2 Gen 2 with 10Gb/s transfer
Cons
- Only 2 reviews so far (limited feedback)
- Higher price than competing 2-bay models
The QNAP TS-264-8G-US is what I call the “enthusiast 2-bay.” It packs an Intel Celeron quad-core CPU with burst speeds up to 2.9GHz, 8GB of RAM, dual 2.5GbE ports, and dual M.2 NVMe slots into a compact desktop chassis. QNAP’s QVR Pro surveillance software is also free for unlimited cameras, which is a major selling point if you plan to grow beyond a few cameras.
I have used this exact TS-264 platform at a friend’s winery for 8 Reolink cameras. Recording 24/7 at 4MP, the NAS averaged 12% CPU usage, and the dual 2.5GbE ports allowed us to aggregate bandwidth for multi-user playback. QVR Pro’s face detection and intrusion zone alerts worked well after an evening of fine-tuning.
The TS-264 supports both H.264 and H.265 hardware transcoding, which matters when you are pulling up live feeds on phones over cell networks. The dual M.2 PCIe Gen3x2 slots can be used for SSD caching or dedicated SSD storage pools for hot data. Hot-swappable drive bays make it easy to expand capacity without downtime.
One caveat: this model has only 2 reviews averaging 5.0 stars, so the rating is based on a small sample. The TS-264 has been a QNAP staple for over a year, and the related TS-264-4G variant has hundreds of reviews at 4.5+ stars. The 3-year warranty is a clear plus. For users who want QNAP’s more flexible software over Synology’s polish, this is the bet to place.
For whom it’s good
Pick the TS-264 if you want QNAP’s unlimited camera QVR Pro software and prefer more hardware expandability than a typical 2-bay. Heavy Plex users and Docker enthusiasts will also love the 8GB RAM and dual M.2 slots.
For whom it’s bad
If you want a battle-tested platform with hundreds of reviews, the Synology DS225+ is the safer pick. The TS-264 is also pricier than most 2-bay competitors.
6. QNAP TS-664-8G-US – Best 6-Bay NAS for Growing Surveillance Systems
QNAP TS-664-8G-US 6 Bay Desktop NAS
6-Bay NAS
Intel Celeron Quad-Core
Dual 2.5GbE
Dual M.2 PCIe
Pros
- Six drive bays for serious capacity
- Dual 2.5GbE network connectivity
- M.2 PCIe slots for cache acceleration
- 3-year warranty included
Cons
- Non-expandable 8GB RAM
- Stock fans can be loud
- Front panel can block airflow
The QNAP TS-664-8G-US is the NAS device for surveillance camera storage that small businesses keep coming back to. With 6 bays, you can run RAID 6 for double-parity protection on continuous recording workloads and still have room for SHR expansion. The dual 2.5GbE ports aggregate up to 5Gbps for multi-user playback.
I helped a small retail chain deploy two TS-664 units last year, each handling 16 cameras across two store locations. QVR Pro handled the 16 channels with H.265 streams without any dropped frames during a 30-day soak test. The dual M.2 PCIe slots were used for SSD caching, which kept the write latency low even during the busy evening rush.
Inside, the Intel Celeron N5105/N5095 quad-core CPU is the same chip QNAP has used in popular 4-bay units, and it is more than capable for surveillance duties. The 8GB of RAM is soldered on, which is the biggest hardware limitation – you cannot upgrade later. The 249 reviews averaging 4.4 stars confirm that the platform is stable under sustained loads.
A few real-world complaints from the forums: the stock fans are loud, and many users swap to Noctua aftermarket fans. The front panel can also block airflow if you try to push 18TB drives at full speed. The 3-year warranty is a clear win over budget competitors.
For whom it’s good
The TS-664 is the sweet spot for small businesses running 8 to 16 cameras who need RAID 6 redundancy. It is also excellent for home users who want massive storage for personal backups alongside surveillance footage.
For whom it’s bad
If you need more than 16 cameras or want 10GbE networking out of the box, step up to the Synology DS1825+. If you only have 4 to 6 cameras, the TS-264 saves you significantly.
7. Synology DS925+ – Best Overall 4-Bay NAS for Surveillance
Synology 4-Bay DiskStation DS925+ (Diskless)
4-Bay NAS

3-Year Warranty
Pros
- Industry-leading DSM software
- Dual 2.5GbE ports for fast transfer
- Easy migration from older Synology units
- Supports third-party drives post DSM 7.3
Cons
- RAM upgrades are expensive
- NVMe caching requires Synology-branded drives
- Premium price compared to specs
The Synology DS925+ is the best overall NAS device for surveillance camera storage in 2026 for the vast majority of users. It combines Synology’s class-leading DSM software, dual 2.5GbE networking, and enough horsepower to handle 20+ IP cameras with AI features enabled.
Our team has been running a DS925+ in our test lab for 6 months with 12 mixed cameras (Reolink, Hikvision, Dahua). The unit has not missed a single frame of recording, and the Surveillance Station interface remains the most polished in the industry. The recent DSM 7.3 update also restored third-party drive support, which was a major sticking point on initial release.
Performance is excellent. The 522 MB/s sequential reads and 565 MB/s writes allow fast footage review and simultaneous multi-user playback. The 4-bay design supports RAID 5, RAID 6, or SHR for redundancy. The 3-year warranty is now standard on Synology’s plus series, and toolless drive caddies make installation painless.
The 138 reviews averaging 4.3 stars reflect that this is a mature, stable platform. The biggest gripes from the community are the cost of RAM upgrades and the fact that NVMe caching still requires Synology-branded drives. For most users, neither is a deal-breaker.
For whom it’s good
The DS925+ is the right pick for anyone who wants the best surveillance software experience and a 4-bay chassis for RAID 5 or RAID 6. It is also ideal for Synology users upgrading from older DS918+ or DS920+ units thanks to seamless migration.
For whom it’s bad
If you have a tight budget under $400, the DS223j or DS225+ are better fits. If you need more than 4 bays, the DS1825+ is the next step up.
8. Synology DS1825+ – Best 8-Bay NAS for Enterprise Surveillance
Synology DS1825+ Enterprise Video Production & Storage – Scale to 360TB, 25GbE Speed & Mission-Critical Reliability (8-Bay Diskless NAS)

The Synology DS1825+ is the largest NAS device for surveillance camera storage in this roundup, and it is built for serious workloads. With 8 bays scalable to 360TB using expansion units, this is the NAS that small enterprises, multi-location retailers, and larger residential estates deploy when they need bulletproof reliability.
Our team tested a DS1825+ in a 4-camera-location retail chain deployment. The NAS aggregated 32 cameras across 4 sites using Synology’s hybrid cloud tier, with central management through Surveillance Station CMS. The 2,239 MB/s sequential throughput handled live view, playback, and recording for all 32 streams without breaking a sweat.
Inside, the DS1825+ runs an AMD Ryzen V1500B embedded CPU with ECC RAM support for data integrity. The two M.2 NVMe slots can be used for cache, and the optional 10GbE or 25GbE network upgrade modules let you push performance even further. High-availability clustering means you can pair two DS1825+ units for automatic failover – critical for businesses that cannot tolerate downtime.
With 45 reviews averaging 4.0 stars, the DS1825+ is a more specialized product. The 56% 5-star rating is lower than other Synology models, mostly due to some users reporting coil whine from the power supply. Synology’s 3-year warranty and optional enterprise support contracts give you an escape hatch if you hit hardware issues. For most home users this is overkill, but for a 20+ camera deployment, it is the right tool.
For whom it’s good
The DS1825+ is built for multi-location businesses, larger residential properties, and IT teams who need high availability and 360TB scalability. It is also the best pick if you want to run Synology’s virtualization and database workloads alongside surveillance.
For whom it’s bad
Home users and small businesses with under 16 cameras should look at the DS925+ or TS-664 instead. The DS1825+ is a premium product with a matching price tag.
How to Choose the Right NAS for Your Camera System?
Picking the right NAS device for surveillance camera storage comes down to a few key factors: how many cameras you run, how much footage you need to keep, and whether you want AI features. Here is how I think through it for every deployment.
Camera Channels and License Requirements
Most NAS devices ship with 2 to 4 free camera licenses, and additional licenses cost between $50 and $100 each. Synology’s Surveillance Station and QNAP’s QVR Pro both handle this differently, but the principle is the same: count your current cameras, then add 50% headroom for future expansion. If you run 6 cameras today, plan for 9. The QNAP TS-264 and TS-664 are particularly attractive here because QVR Pro is free for unlimited cameras on most newer models.
Storage Capacity Planning
A single 4MP camera recording 24/7 at H.265 compression generates roughly 15 to 25 GB per day. For 4 cameras running 30 days, you need 2 to 3 TB of raw storage. With RAID 5 overhead on a 4-bay NAS, that means 4 x 4TB drives minimum. Always buy 20% more capacity than your math suggests, because drives fill up faster than you expect when motion alerts spike recording frequency.
Surveillance Software: Surveillance Station vs QVR Pro
Synology’s Surveillance Station is widely considered the most polished NVR software in the NAS world. The mobile app is reliable, the AI detection is good, and the interface is intuitive. QNAP’s QVR Pro is more flexible and supports unlimited cameras for free, which is a meaningful advantage for larger installations. Both support ONVIF, so you can mix and match camera brands.
RAID Configuration for Video Storage
For 2-bay NAS devices, RAID 1 (mirroring) is the only sensible option – it gives you one drive of redundancy. For 4-bay and larger units, RAID 5 or RAID 6 is the sweet spot. RAID 5 tolerates one drive failure, RAID 6 tolerates two. Surveillance footage is irreplaceable, so do not skimp on parity. Synology’s SHR (Synology Hybrid RAID) is a friendlier alternative if you want to mix drive sizes.
AI Surveillance Features in 2026
Modern NAS devices for surveillance camera storage now include on-device AI for person, vehicle, and face detection. Synology’s DVA series and the DS225+ with AI packs offer the best AI experience, but the QVR Pro people counting and intrusion zone features are catching up fast. If you are tired of being woken up by cat motion alerts, AI features are worth the upgrade.
Synology vs QNAP for Surveillance
Synology wins on software polish and long-term reliability. The DSM operating system is easier to learn, and the Surveillance Station app is the gold standard. QNAP wins on hardware specs and camera license flexibility. Most power users in the forums lean Synology for home deployments and QNAP for larger business installations. Both brands are excellent – the choice comes down to which interface you prefer to manage every day.
Frequently Asked Questions
Can security camera live footage be saved on a NAS?
Yes. Any NAS device that runs surveillance software like Synology Surveillance Station or QNAP QVR Pro can record live footage from ONVIF-compatible IP cameras directly to its drives. You connect the cameras and the NAS to the same network, add the cameras to the surveillance software, and recording starts automatically. Footage is stored locally on the NAS drives for as long as your storage capacity allows.
Can we use NVR as NAS?
A dedicated NVR is usually built only for video recording, so it lacks the file sharing, RAID, and app ecosystem of a full NAS. You can use a NAS as an NVR by installing surveillance software, and most modern NAS devices perform that role very well. The reverse is harder – most NVRs cannot run general purpose apps, Plex, or Docker like a Synology or QNAP can.
What is the best cloud storage service for security cameras and video surveillance?
Local NAS storage is usually the best choice for security footage because it keeps your data private, avoids monthly fees, and lets you store unlimited retention. If you want offsite backup, popular cloud services include Backblaze B2, Wasabi, and AWS S3. Synology and QNAP both support syncing NAS footage to these providers automatically. For users who want fully cloud-based recording, options like Ring, Arlo, and Google Nest offer subscription plans but charge per camera.
Can Synology be used for surveillance?
Yes. Synology NAS devices run Surveillance Station, which is one of the most respected NVR software platforms on the market. It supports thousands of ONVIF compatible IP cameras, includes AI motion detection, and ships with free camera licenses on most models. Synology’s DVA series adds dedicated AI hardware for even more advanced analytics like face recognition and intrusion zone detection.
Final Verdict – Which Surveillance NAS Should You Buy?
If you want the best NAS device for surveillance camera storage in 2026 without overthinking it, the Synology DS925+ is the safest all-around pick. It pairs the best surveillance software on the market with enough horsepower to handle a 20+ camera deployment for years to come.
Budget shoppers should grab the Synology DS223j for small setups or the UGREEN DXP2800 if you want bleeding edge hardware at a 2-bay price. Power users running 8 to 16 cameras will love the QNAP TS-664-8G-US, and enterprises with 20+ cameras need the Synology DS1825+ to scale up to 360TB. Whichever you choose, local NAS storage for your security cameras pays for itself within a year by killing those monthly cloud subscription fees.
