On-prem recording and analytics
Powered by Synology DSM, the footage is kept on the device, with options to flexibly backup or archive to other devices and locations.
Security & privacy
- No footage is uploaded to the cloud for storage or analysis. Keep sensitive information secure and locked down.
No recurring fees
- One-time hardware and license purchase, with no monthly subscriptions or additional fees for software updates.
Real-time results
- Instead of post-event analysis, Deep Learning NVR DVA3221 can notify security operators immediately when incidents occur.
Ease of integration
- 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.

Deep Learning NVR DVA3221 Comprehensive VMS platform
Deep Learning NVR DVA3221 is an all-in-one NVR solution, combining video recording, analysis, and advanced video management.
Action rules
- Set up security policies so that when a condition is met, corresponding actions can be triggered automatically, reducing the time and effort needed for manual interventions.
Easy to set up and operate
- 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 on top of Synology DSM, graphical interfaces simplify complicated tasks, while still retaining flexibility.
Cross-platform, internet-optional
- 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.
API ready
- Comprehensive documentation is available to third-party developers looking to integrate their products or applications with Surveillance stations.
One-stop support
- An integrated system means a single point of support for both the hardware and software solution, simplifying setup and maintenance efforts needed.
After adopting the surveillance solution provided by Synology, we have fundamentally solved all the problems we had using a traditional system. Aside from allowing us to record stably, it also saves us a lot of time pulling out footage, as our surveillance officers are required to do so daily. Moreover, Surveillance Station counts and tracks people flow, allowing us to analyze the data and bringing in more revenue.

Frequently Asked Questions
Are specialized cameras required for video analytics? What is the recommended resolution for each camera?
- All cameras listed under the
- are supported. We recommend installing cameras that support FHD 1920×1080 resolution and support 20 FPS (frames per second) or higher. Refer to the
- for more information.
What notification methods are supported when an event is triggered?
- You can set up custom alerts via email, SMS, and the DS cam mobile app.
Can Surveillance stations detect strangers and issue alerts?
- Yes. Using the facial recognition feature, alerts can be sent out when the system detects a person that cannot be matched to an existing entry. See the
Face Recognition Admin Guide for additional information.
Can the facial recognition feature be used together with door controllers and other devices to implement multi-step security processes?
- Yes. Surveillance Station has support for Axis Door Controller,
- , POS systems, and other devices. By setting up
- , you can leverage the events on one device to trigger another action somewhere else.
How does the system handle lighting changes, shadows, and weather conditions such as rain?
- Leveraging advanced algorithms powered by the GPU, Surveillance Station’s People and Vehicle detection functionality can detect and differentiate between those objects of interest with high accuracy, even in more challenging lighting environments.
What external integration / API capabilities are supported?
- Surveillance Station API can be used to customize deployments for specific needs. For example, you can perform external analysis and bookmark frames of interest, pass facial recognition or people counting results to an external system. For more information, refer to the
- .
Does the DVA support NAS functionality found on other devices running DSM?
- Synology DVA series supports most features found on other Synology NAS and has access to Synology Package Center. For a comprehensive list of supported add-ons, refer to the
