Synology launches DVA7400 on-premises surveillance appliance

Synology has launched the DVA7400 surveillance appliance, a system for large-scale video monitoring run entirely on-premises.

Aimed at organisations managing camera networks across multiple sites, the appliance can serve as both a recording platform and a central management server for distributed surveillance deployments through the Central Management System in Surveillance Station.

Built on a 2U 12-bay rackmount chassis, the DVA7400 is designed to process up to 100 high-resolution camera feeds. It can also run up to 40 real-time deep learning analytics tasks simultaneously, with recordings and AI metadata stored on the appliance rather than in the cloud.

That approach reflects growing demand among businesses and public sector bodies for local control over surveillance data, particularly where privacy requirements and regulatory obligations limit the use of external hosting. All data remains within an organisation's own infrastructure.

Search tools

A key part of the launch is a set of investigation features designed to reduce the time needed to review archived footage. The DVA7400 includes Semantic Video Search, which allows operators to query video archives from up to 100 recording feeds using natural language.

Searches are handled by a dedicated hardware accelerator running on isolated resources, allowing archive queries to run without interrupting the appliance's 40 live analytics tasks.

Other search and analysis functions include Attribute Search, which lets users filter people or vehicles by visual characteristics such as clothing colour or vehicle type. The system also includes Licence Plate Recognition for access control and investigative work.

The appliance supports real-time analytics including Face Recognition, Crowd Detection, Intrusion Detection, and People and Vehicle Counting. Another feature, Find Repeated Objects, is planned for a later update and is intended to help reconstruct an individual's movement across different locations.

Existing cameras

The DVA7400 is also positioned as a way to add AI analysis to existing surveillance estates rather than requiring wholesale hardware replacement. Server-side analytics and broad ONVIF profile support allow organisations to use the system with their current cameras.

That may appeal to companies looking to expand monitoring and investigation tools without replacing installed camera fleets, which can be costly in large industrial, retail, transport, or campus environments. The ability to manage multiple sites from a single platform could also reduce operational complexity for security teams overseeing dispersed locations.

Josh Lin, Director of the Synology Surveillance Group, said the launch reflects the company's long experience in physical security.

"The DVA7400 represents the culmination of Synology's nearly two decades of expertise in physical security," Lin said.

He added that local processing and central oversight are central to the product's design.

"By combining centralised management for distributed camera fleets with completely localised AI analytics, it empowers enterprises to scale their surveillance infrastructure without compromising on data privacy," he said.

The launch adds to a broader industry shift towards bringing AI analysis closer to where data is captured, especially in security settings where latency, bandwidth use, and information control are important. Surveillance vendors have increasingly focused on combining machine learning with local storage and management tools as customers weigh the trade-offs between cloud-based systems and infrastructure kept on site.

For Synology, the new appliance extends its surveillance portfolio further into larger deployments that require both central administration and intensive video analysis. The DVA7400 is available through the company's distributor and systems integrator network.
