Synology DVA3221
The Synology DVA3221 is a 4-bay desktop network video recorder (NVR) for storing and analysing camera footage. It uses a quad-core Intel Atom C3538 processor with a frequency of 2.1GHz and an AES-NI hardware encryption engine. The built-in NVIDIA GeForce GTX 1650 graphics card processes deep learning algorithms in real time directly on local storage, without sending data to the cloud. The Surveillance Station system manages up to 32 IP cameras without needing a permanent internet connection. The recorder supports over 8300 IP camera models and the ONVIF standard for easy connection of different brands. Physical connectivity is provided by four gigabit RJ-45 ports, four PoE ports, and three high-speed USB 3.2 Gen 1 ports, along with two eSATA ports. Management is handled via a web browser or the DS cam mobile app, which allows for PTZ camera control and two-way audio.

Video analytics
The device performs twelve concurrent video analytics tasks for instant situation assessment in the monitored area. The integrated algorithms offer facial recognition with 97.04% accuracy and real-time people and vehicle detection to protect a defined perimeter. The system also supports people and vehicle counting, intrusion detection, and licence plate recognition. Users receive instant alerts on their mobile devices when unauthorised subjects are detected.
Centralised management and surveillance
The CMS system unifies the operation and management of multiple recording servers under a single user interface. The system administrator can run remote updates and set up automatic service failover to backup hardware in N+M mode. Linking with online maps like Google Maps or OpenStreetMap makes it easier to locate cameras and incidents in multi-storey or large-scale premises. This process reduces the risk of data loss during a connection failure.
Expansion options
Users can increase the base capacity of the four drive bays by connecting two Synology DX517 expansion units via the eSATA interface. System administrators can create disk arrays and expand the total storage by up to ten additional hard drive bays. The system supports both 3.5" and 2.5" SATA drives to create a volume. The base 8GB of RAM can be expanded up to 32GB.
Rapid camera deployment
The setup wizard simplifies adding new surveillance points by proactively searching within an IP address range. Users can export the camera configuration to a spreadsheet and then perform a batch import of the settings in a single step to speed up installation in large properties. Quickly replicating settings between cameras makes it easy to expand an existing network. The system supports H.264 and H.265 video codecs for compatibility with various manufacturers.
Data security
Recorded streams are encrypted using HTTPS and SRTP protocols, which prevents unauthorised signal interception. The dual recording feature saves video footage simultaneously to two independent servers or to the C2 Surveillance cloud service. Archived recordings are protected by a special encryption password to prevent unauthorised data access. This lets the user retain full control over their data directly on local storage without needing to pay subscription fees.
