Video footage is transformed into actionable insights with advanced deep learning-based analytics, enhancing security without requiring additional personnel.
Identify employees and key or prohibited personnel in real time to deliver better on-prem security.
Detect people or vehicles in off-limits areas for increased situational awareness.
Create actionable insight on venue occupancy and pathway efficiency with bidirectional counters.
Issue alerts when a vehicle or person trespasses a virtual line, enabling flexible perimeter monitoring.
Powered by Synology DSM, footage is kept on the device, with options to flexibly backup or archive to other devices and locations.
No footage is uploaded to the cloud for storage or analysis. Keep sensitive information secure and locked down.
One-time hardware and license purchase, with no monthly subscriptions or additional fees for software updates.
Instead of post-event analysis, DVA3221 can notify security operators immediately when incidents occur.
Compatible with over 7,600 IP cameras, and with ONVIF support, there is no need to replace or be locked into a specific brand of cameras.
DVA3221 is an all-in-one NVR solution, combining video recording, analysis, and advanced video management.
Set up security policies so that when a condition is met, corresponding actions can be triggered automatically, reducing time and effort needed for manual interventions.
Designed to be simple for both administrators and operators, adding and managing cameras, navigating between live feeds and recordings, and configuring permissions and backup tasks are all straightforward. Built ontop of Synology DSM, graphical interfaces simplify complicated tasks, while still retaining flexibility.
Access your surveillance system on any system through a browser, our PC/Mac/Linux client, or through mobile apps, both with or without internet access.
Comprehensive documentation available to third-party developers looking to integrate their products or applications with Surveillance Station.
An integrated system means a single point of support for both the hardware and software solution, simplifying setup and maintenance efforts needed.
