Predominant colors of the product

Indicates whether the device can forward an incoming call to another number or device automatically. A value of Yes means the feature is available, while No means it is not supported.

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.

Indicates whether the product includes an Ethernet LAN interface for wired network connectivity, allowing data transmission over RJ‑45 or compatible cables.

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.

The range of electrical voltage that a device can safely accept from its power source, expressed in volts (V). It specifies the minimum and maximum supply voltages compatible with the product, covering both AC and DC inputs where applicable.

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.

A list of network protocols that a device can use for configuration, monitoring and remote management, such as SNMP, HTTP/HTTPS, Telnet, SSH or other standard interfaces. Each protocol is represented by its common name and may be separated by commas or slashes in the source data.

The highest theoretical speed at which a device can transfer data over its Ethernet interface, expressed in bits per second or multiples such as kbps, mbps, gbps. It represents the maximum throughput achievable under optimal conditions and is useful for comparing wired network performance across devices.

The greatest distance over which a product can operate or communicate effectively in an outdoor environment, expressed as a linear measurement. It indicates the maximum reach or coverage area that the device is designed to support under typical conditions.

The total count of Voice‑Over‑Internet‑Protocol (VoIP) user accounts that can be configured or supported on the device. It represents how many separate telephone lines or extensions are available for simultaneous use, helping buyers compare capacity across models.

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.

The electrical current drawn by a device from its power source, expressed in amperes (A). It indicates how much current the product consumes during normal operation and helps determine compatibility with power supplies or USB ports.

The electrical potential difference that a device delivers to its load, expressed in volts (V). It indicates the nominal voltage supplied by the product’s power output and is useful for matching it with compatible accessories or systems.

Indicates whether a quick‑start guide is provided with the product. A value of "Yes" means that a brief, introductory manual or overview is included to help users get started quickly; "No" indicates that no such guide is supplied.

A list of cryptographic and authentication methods that a device can use for secure communication or data protection. Each entry represents a distinct algorithm or protocol, such as encryption ciphers (e.g., AES, WEP), authentication mechanisms (e.g., RADIUS, WPA‑PSK), or network security protocols (e.g., HTTPS, SSL/TLS). The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.

A list of network communication protocols that a device can use or support, such as TCP/IP, HTTP, HTTPS, FTP, DHCP, DNS, and various wireless standards. Each protocol is represented by its standard name and may be separated by commas or slashes in the source data.

Indicates whether the product can be securely mounted to a wall or other vertical surface using standard mounting hardware.

The mass of the product expressed in a standard unit such as grams or kilograms. It represents how heavy the item is and can be used for shipping calculations, handling instructions, or consumer information.
