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.

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.

Indicates whether the product has an HDMI output interface for transmitting digital audio and video signals.

A list of the functions or statuses that an LED indicator on a device can display, such as power status, activity, link, and other operational signals.

The highest electrical power that a device can draw or consume during operation, expressed in watts (W). It represents the peak energy usage of the product and is useful for estimating maximum power requirements, comparing efficiency across similar devices, and ensuring compatibility with power supplies.

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.

A list of mobile operating systems that the product supports, including specific versions and architectures when relevant. Each value represents a distinct OS that is compatible with the device.

The total count of individual cooling fans that are part of the product or its components. This value indicates how many separate fan units are installed, such as in a graphics card, CPU cooler, case, or other hardware assemblies.

The total count of hard disk drives that the product can accommodate or support. It indicates how many separate HDD units are physically installable or usable within the device, regardless of size, interface type, or capacity.

The total number of individual users that can be supported or accessed by the product or service. It represents a count of distinct user accounts, connections, or licenses and is expressed as an integer value.

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 list of the playback modes that a device can handle, such as single image view, slideshow, video play, or thumbnail preview. Each value represents a distinct mode in which captured content can be viewed directly on the product.

Indicates how many Power over Ethernet (PoE) ports are available on the device. The value is a simple integer representing the total count of physical PoE connectors that can supply power to compatible devices such as IP cameras, wireless access points or VoIP phones.

The pixel dimensions of a screen when captured or recorded, expressed as width by height (e.g., 1920x1080). It indicates the resolution that can be obtained from a device’s display during capture or recording sessions and is useful for comparing visual quality across devices.

The pixel dimensions that a device can output or support, expressed as width by height (e.g., 1920x1080). It indicates the maximum resolution available for display content on the product and may include multiple supported resolutions separated by commas.

The maximum electrical power that a network device can supply to connected Power over Ethernet (PoE) devices, expressed in watts (W). It represents the total PoE budget available for powering attached equipment such as switches, access points, or cameras.

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.

Indicates whether the product has built‑in Wi‑Fi capability, allowing it to connect to wireless networks without requiring external adapters or dongles.
