NAS Surveillance Solutions — Top 5 Options in the UK (2026)
Network-attached storage (NAS) surveillance solutions provide a centralized, private and scalable way to store and manage video from IP cameras. In the UK market for 2026, NAS is popular across homeowners, small businesses, retailers and local authorities because it offers local control of sensitive footage, lower ongoing cloud costs for long retention periods, flexible retention policies and straightforward integration with ONVIF-compliant cameras and third-party analytics. Consumers and organisations choose NAS-based surveillance for reliability, offline access during network outages, easier compliance with UK data protection rules, and the option to run AI analytics at the edge to reduce bandwidth and latency. At present this page lists 0 ranked options under the current criteria or filters, which may reflect an undefined or empty product set. Below we explain how NAS surveillance solutions work, what to look for when selecting a system, and how to refine your search to find the right solution for your needs.

Top Picks Summary
Synology DiskStation DS923
The DiskStation DS923+ is best-in-class for small-to-midsize surveillance deployments thanks to a compact 4-bay design, responsive performance and Synology's mature Surveillance Station ecosystem that simplifies camera management and retention. Compared with the larger DS1522+ it offers a more cost-effective entry point, and its software-focused approach typically delivers easier setup and ongoing management than the QNAP and Asustor models on this list.

QNAP QVR Pro TS-464
The QVR Pro TS-464 is a surveillance-focused 4-bay NAS built around QNAP's QVR Pro platform, offering flexible camera workflows and strong real-time monitoring tools that make it attractive for users prioritizing feature-rich surveillance software. It generally competes well on price-to-feature ratio against the Synology units and provides a more specialized surveillance experience than the more general-purpose DS923+ or the budget Asustor option.
Synology DiskStation DS1522
The DiskStation DS1522+ is positioned for larger or growing surveillance sites that need extra drive bays and easier capacity expansion, delivering longer retention and higher camera counts without sacrificing Synology's robust data-protection features. Compared with the DS923+ it trades a slightly higher initial cost for expandability, and versus the QNAP TS-673A or TS-464 it favors Synology's integrated software and snapshot-rich storage stack for reliability over raw expandability.
Estimated£600 – £800
QNAP TS-673A
The TS-673A is the market leader on this list for heavy-duty surveillance workloads thanks to its emphasis on I/O expandability and upgrade paths (PCIe/extra ports) that support 10GbE, accelerators or additional NVMe cache for high camera-count environments and AI analytics. While it comes at a premium compared with the midrange Synology and Asustor models, its hardware flexibility and throughput make it the best choice where performance and future-proofing matter most.
Asustor Lockerstor 4 AS6604T
The Lockerstor 4 AS6604T is a cost-conscious 4-bay NAS that delivers solid baseline performance, efficient power usage and practical features like NVMe caching, making it an economical option for small-home or entry-level surveillance systems. It undercuts the higher-priced Synology and QNAP models on raw cost while providing enough capability for modest camera deployments, though it offers fewer advanced surveillance-specific software features than the Synology and QNAP offerings.
Why research supports NAS for surveillance
A body of technical research, government guidance and industry analysis supports the practical benefits of local storage and edge processing for surveillance. Key themes include reduced latency and bandwidth use from processing at the edge, improved data protection when footage is held under local control, and lower total cost of ownership for long-term retention compared with pure cloud storage. UK guidance from data protection authorities and cybersecurity centres highlights the importance of secure storage, access controls and clear retention policies, all of which align with best practice for NAS deployments.
Edge computing research shows local processing can reduce response times for analytics and alarms, improving real-time detection and reducing false positives.
Data protection guidance in the UK emphasises secure storage and controlled access. Keeping footage on a trusted NAS can simplify compliance with retention and access requirements.
Market analyses consistently note that for long retention windows and high-resolution video, hybrid or local storage typically lowers ongoing costs compared with continuous cloud storage.
Security research stresses the need for regular updates, strong authentication and encrypted storage. NAS vendors and integrators increasingly support these safeguards.
User experience studies indicate that installers and administrators prefer systems that offer clear management interfaces, remote access with secure tunnels, and easy expansion as camera counts grow.
