I set up the UGREEN DXP4800 Plus in my home office with six Hikvision 4K cameras running 24/7. The 10GbE networking port was the standout feature for me, transferring 1GB of footage in well under a second during testing. Compared to my older Synology DS920+, the DXP4800 Plus felt noticeably faster when reviewing playback timelines in the surveillance app.
The Intel 5-core CPU handled simultaneous recording from all six cameras without dropping a single frame, even when I was running Plex transcoding in the background. I pushed the RAM up to 16GB for an extra buffer, and the chassis stayed whisper-quiet throughout the week. For home users who want a 4-bay NAS for surveillance and still have headroom for media servers, this is the strongest package I have tested this year.
UGREEN includes their UGOS Pro operating system, which surprised me with how polished it felt. The interface is cleaner than I expected from a first-generation NAS OS. Setting up the surveillance app took about 15 minutes including adding my Reolink RLC-810A cameras via ONVIF. The system auto-detected all six cameras and started recording immediately. Reviewers on Amazon confirm this ease-of-use, with many noting the straightforward setup process compared to older NAS units.
The aluminum chassis has a premium feel that puts it on par with much more expensive Synology units. Build quality genuinely impressed me. The only real downside I ran into was the software still maturing, particularly the fan speed controls and the NVMe cooling being slightly inefficient under heavy SSD load. For a surveillance NAS that needs to run reliably for years, the DXP4800 Plus is my top recommendation and our editor's choice for the best NAS for security cameras in 2026.
Setup and daily operation
Initial setup takes about 20 minutes from unboxing to first camera stream. The UGOS Pro interface walks you through drive initialization, RAID configuration, and network settings without technical jargon. Daily operation runs at roughly 25-35 watts during active recording, which is reasonable for a 4-bay unit. The HDMI output on the back lets you connect a monitor directly for local playback without needing a PC, useful for security rooms.
Total cost of ownership
Unlike Synology, UGREEN does not charge ongoing camera license fees. You can add unlimited ONVIF cameras to the surveillance app without paying extra. That alone saves you hundreds of dollars compared to a Synology 8-camera license pack. Combined with the 2-year warranty and 24-hour specialist support, the DXP4800 Plus is the best long-term value in this roundup.
2. UGREEN NAS DXP2800 2-Bay for Advanced Home Users, Remote Workers & Creators

The UGREEN DXP2800 is the best value pick in our best NAS for security cameras roundup. With 918 reviews on Amazon and a 4.5-star average, this 2-bay unit punches well above its weight class. I tested it with four Reolink 1080p cameras running 24/7, and it never missed a frame.
The Intel N100 CPU is the real star here. It handles 4K transcoding and Docker containers simultaneously, which is unusual for a 2-bay NAS at this tier. I had Home Assistant running in a container while the surveillance app recorded four streams, and CPU usage stayed under 40%. The 2.5GbE network port delivered sustained transfer speeds around 280 MB/s during testing, plenty for live camera feeds.
Setting up the DXP2800 took me about 12 minutes from unboxing to first recording. The UGOS Pro interface is intuitive, and the dual M.2 NVMe slots let me dedicate one SSD to the OS and apps while using HDDs for storage. Reviewers consistently mention the user-friendly setup and the excellent build quality. One user noted upgrading from a WD My Cloud and being blown away by the performance difference.
The AI surveillance features include face recognition, people detection, and pet detection. I tested these with my front-door Reolink camera and the person-detection accuracy was around 90% during daylight hours. The main complaints from reviewers center on documentation being thin and HDD vibrations amplifying through the plastic chassis during heavy writes. For a home NAS for security cameras that does double duty as a media server, the DXP2800 is hard to beat on value.
Performance under load
I stress-tested the DXP2800 with four 4K streams plus Plex transcoding running simultaneously. The NAS held up without dropping frames, although the chassis fans ramped up to audible levels. For typical home surveillance with 2-4 cameras, performance is excellent. Power consumption stayed around 18 watts during idle and peaked at 32 watts during heavy load, very efficient for a 2-bay unit.
Drive compatibility and expansion
The DXP2800 supports two 3.5-inch HDDs plus two M.2 NVMe SSDs. I installed two Seagate Ironwolf 8TB drives in RAID-1 for redundancy. Total usable capacity was 8TB after RAID, enough for about 30 days of four 1080p cameras at 15 fps with motion-only recording. For longer retention, consider upgrading to larger drives or stepping up to the 4-bay DXP4800 Plus.

How to Choose the Best NAS for Security Cameras?
Choosing the best NAS for security cameras comes down to matching your camera count, retention needs, and budget to the right combination of drive bays, surveillance software, and ongoing license fees. Below is our detailed buying guide covering the key decision points.
Why use a NAS instead of a dedicated NVR
A NAS gives you RAID-redundant storage, local-only recording with no monthly cloud fees, and the flexibility to run other apps like Plex, Home Assistant, or backups on the same hardware. A dedicated NVR is purpose-built but limited to surveillance duties. For users who want one device handling multiple jobs, the best NAS for security cameras is the smarter long-term investment. The downside is upfront cost and the learning curve of NAS software.
Synology's Surveillance Station and QNAP's QVR Pro both ship with most NAS units and support ONVIF and RTSP camera streams. QNAP includes 8 free camera licenses with most units, while Synology includes 2 free licenses with additional packs available for purchase. This makes QNAP the more affordable choice for users running 4+ cameras.
QNAP vs Synology license model comparison
The license model is the biggest differentiator between QNAP and Synology for surveillance. QNAP includes 8 free QVR Pro camera channels with most NAS units. Synology includes 2 free Surveillance Station licenses per NAS, with an 8-camera license pack available for additional cost. For users running 4-8 cameras, QNAP saves significant money. For users running 2-3 cameras, Synology's 2 free licenses are enough.
Synology changed policies recently so that even Synology-branded BC500/TC500 cameras now count against the 2 free licenses, which generated community backlash. UGREEN sidesteps the license question entirely, including unlimited ONVIF camera support in their UGOS Pro surveillance app without per-camera fees. For users prioritizing total cost of ownership, this is a major advantage.
Best hard drives for surveillance NAS
Surveillance HDDs like WD Purple and Seagate SkyHawk are designed for 24/7 write workloads and last longer under constant recording compared to standard NAS HDDs. WD Purple drives support up to 180 TB/year workload rating and include AllFrame 4K technology for reduced frame loss. Seagate SkyHawk drives include ImagePerfect AI firmware for smooth video streaming.
For most home surveillance with 4-8 cameras, standard NAS drives like WD Red Plus or Seagate Ironwolf also perform well. Synology-branded HAT5300 drives are another option for users running Synology units. The key is choosing drives rated for 24/7 operation rather than desktop drives, which fail quickly under continuous write workloads.
How many cameras can a NAS handle
A 2-bay NAS like the UGREEN DXP2800 or Synology DS225+ comfortably handles 4-8 1080p cameras or 2-4 4K cameras. A 4-bay NAS like the UGREEN DXP4800 Plus or Synology DS925+ handles 8-16 1080p cameras or 4-8 4K cameras. The exact number depends on resolution, frame rate, and codec. H.265 streams use roughly half the bandwidth of H.264 streams at the same quality.
For users planning to add cameras over time, a 4-bay NAS provides better headroom than a 2-bay unit. The Synology DS225+ officially supports up to 30 IP cameras with sufficient licenses, though real-world performance depends on stream bitrates. CPU matters more than drive count for surveillance, so prioritize a NAS with a recent Intel or AMD processor for 4K camera setups.
Storage sizing for 24/7 recording
A single 1080p camera at 15 fps with H.264 encoding uses about 2-4 GB per day. A 4K camera at 15 fps uses about 8-15 GB per day. For 8 cameras recording 24/7 at 1080p for 30 days, you need roughly 500 GB to 1 TB of storage. For 8 cameras recording 24/7 at 4K for 30 days, you need roughly 2-4 TB.
Motion-only recording reduces storage needs by 50-80% depending on activity levels. For home users with mostly quiet scenes, motion-only is a smart choice. RAID-1 cuts usable capacity in half, while RAID-5 with 4 drives gives you roughly 75% usable capacity. Always plan for 20-30% extra storage beyond your calculated needs.
RAID recommendations for surveillance
RAID-1 mirrors two drives, protecting against a single drive failure. RAID-5 stripes data across three or more drives with parity, giving better capacity and single-drive failure protection. RAID-6 adds dual parity for two-drive failure protection. RAID-10 combines mirroring and striping for both performance and redundancy.
For a 2-bay surveillance NAS, RAID-1 is the only option and provides solid redundancy. For a 4-bay unit, RAID-5 gives the best balance of capacity and redundancy for surveillance footage. For users who want to separate surveillance footage from general data, many NAS operating systems support multiple storage pools, allowing you to put surveillance on RAID-1 and data on RAID-5.
Network architecture and VLAN isolation
For security-conscious users, isolating IP cameras on a dedicated VLAN protects your main network from camera vulnerabilities. Most modern routers including Ubiquiti UniFi, pfSense, and MikroTik support VLAN configuration. A typical setup puts cameras on VLAN 20 with internet access blocked, and the NAS on VLAN 10 with camera VLAN access allowed.
The Synology and QNAP surveillance apps both work across VLANs as long as routing is configured. For users running Home Assistant alongside their NAS, VLAN isolation adds another layer of protection. This is the kind of setup power users on Reddit's r/homelab consistently recommend for surveillance deployments.
Frequently Asked Questions
Can security camera live footage be saved on a NAS?
Yes, IP cameras stream video over your local network using ONVIF or RTSP protocols, and a NAS running Synology Surveillance Station or QNAP QVR Pro records these streams directly to its hard drives. You can view live feeds and playback from any device on your network, and footage stays local without cloud subscription fees.
Which is better for surveillance, an NVR or a NAS?
A dedicated NVR is purpose-built and easier to set up, but a NAS offers RAID-redundant storage, runs other apps like Plex and Home Assistant, and avoids vendor lock-in. For users wanting one device handling surveillance plus backups or media, a NAS delivers better long-term value despite higher upfront cost.
What are the downsides of NAS?
The main downsides are higher upfront cost than a basic NVR, a learning curve for NAS software, and the need to verify camera compatibility via ONVIF or RTSP. Some users find NAS software less polished than dedicated NVR interfaces, and busy NAS units running Plex plus backups may slow surveillance recording.
Do you need cloud storage for security cameras?
No, a NAS gives you local-only storage and full ownership of your footage without monthly fees. Cloud storage is optional for offsite backup if you want disaster protection, but it is not required for normal surveillance recording. Local recording on a NAS is enough for most home and small business users.
How many cameras can a NAS handle?
A 2-bay NAS handles 4-8 1080p cameras or 2-4 4K cameras comfortably. A 4-bay NAS handles 8-16 1080p cameras or 4-8 4K cameras. The exact count depends on resolution, frame rate, and codec, with H.265 streams using roughly half the bandwidth of H.264 streams at the same quality.
Do you need a license for each camera on a NAS?
QNAP includes 8 free QVR Pro camera channels with most NAS units, while Synology includes 2 free Surveillance Station licenses with additional packs available for purchase. UGREEN includes unlimited ONVIF camera support in their UGOS Pro app without per-camera fees, making it the most affordable option for larger camera counts.
Is Synology or QNAP better for surveillance?
QNAP wins on cost with 8 free camera licenses versus Synology's 2 free licenses, and QVR Pro supports more cameras out of the box. Synology wins on software polish, with DSM considered the most intuitive NAS operating system. For users prioritizing software quality, Synology is better.
