Synology Deep Learning NVR DVA3221

The range of alternating current voltage that the product accepts from its power source, expressed in volts (V). It indicates the minimum and maximum supply voltages compatible with the device across different regions.

A list of brand names that the product is compatible with. Each entry represents a manufacturer whose products can be used with or alongside the item.

A list of web browsers that the product can run or support, typically including major desktop and mobile browsers such as Chrome, Firefox, Safari, Edge, Internet Explorer, Opera, and others. Each value represents a distinct browser name or version range that has been verified to work with the device.

Indicates whether the product contains a built‑in central processing unit (CPU) that can execute instructions without requiring an external processor module. A value of "Yes" means the device has such a CPU; "No" means it does not.

A list of the cable types that are supplied with the product, such as USB, HDMI, VGA, DisplayPort, LAN (RJ‑45), SATA, audio or other relevant connectors.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

Represents how many serial (COM) connectors are available on the product. The value is a simple integer indicating the total count of COM ports, regardless of version or configuration.

Represents the total count of Ethernet LAN (RJ‑45) interfaces available on a product. The value is an integer indicating how many physical Ethernet ports are present, regardless of speed or generation.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

List of the physical interface(s) used by a hard drive together with the number of bays it occupies, such as "2 x SATA (2 x Bay)" or "1 x M.2 PCIe". This attribute helps users determine both the connection type and how many drives can be installed in an enclosure or system.

The physical width of a hard disk drive expressed in inches or centimeters. It indicates the standard size that determines which enclosures, bays, and mounting hardware are compatible with the drive.

The total amount of internal memory available in a device, expressed as a data size such as megabytes (MB) or gigabytes (GB). It indicates how much information the component can hold for active processes and affects multitasking performance.

A list of natural languages in which a product is available or supported, including user interface, documentation, and audio options.

The largest amount of digital storage that a product can hold or provide, expressed as a numeric value with an appropriate unit such as GB, MB, TB, or a descriptive label indicating the type of media (e.g., SSD, HDD). This attribute helps users understand how much data can be stored on the device and compare storage options across products.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

A comma‑separated list that specifies the RAID configurations supported by a storage controller or device. Each entry can be a numeric level (e.g., 0, 1, 5, 10) or a special label such as JBOD. This attribute indicates which disk arrangements the system can manage.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

The total count of USB 3.2 Gen 1 (also known as USB 3.1 Gen 1 or SuperSpeed) ports available on the device, indicating how many peripherals can be connected simultaneously via this interface.

A list of video file formats that the product can play or record, including both the compression codec and the file extension. Each value represents a valid combination of technology and format supported by the device’s hardware or software.

The total count of distinct video input ports that a device provides, such as HDMI, VGA, DVI, DisplayPort or other connectors. Each value represents how many separate video signals can be connected simultaneously to the product.
