Grandstream Full HD 3‑Way Video Conferencing System

The frequency of the alternating current supplied to a power supply or charger, expressed in hertz (Hz). It indicates the acceptable operating range for the electrical mains that powers the device, ensuring proper functionality and safety.

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.

Indicates whether the product includes a built‑in screen or display unit that can be used directly for viewing content, such as an integrated monitor on a laptop or a built-in display on appliances. A value of "Yes" means the device has such a display; a value of "No" means it does not.

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.

The highest electrical current a device draws from its power source during normal operation, expressed in amperes (A). It indicates the maximum current that the product requires and helps users verify compatibility with power supplies or sockets.

The electrical potential difference that a device is designed to accept from its power source, expressed in volts (V). It indicates the nominal operating voltage for the product and helps users verify compatibility with local mains or battery supplies.

The pixel dimensions of a display or image, expressed as width by height (e.g., 1920x1080). It indicates how many pixels are used to render visual content and is commonly used for monitors, TVs, smartphones, cameras, and digital images.

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

Maximum theoretical speed at which a device can send or receive data over its Ethernet LAN interface, expressed in megabits per second (Mbps) or gigabits per second (Gbps). It represents the upper bound of throughput under optimal conditions and is useful for comparing network performance between devices with wired connectivity.

Indicates whether a handheld device can be operated from a distance using an external remote control such as infrared, Bluetooth or Wi‑Fi. A value of "Yes" means the product supports remote operation; "No" indicates it does not.

The pixel dimensions of a product’s screen, expressed as width by height (e.g., 1920x1080). It indicates the total number of pixels that compose the display and is used to assess image sharpness and clarity across devices such as monitors, TVs, laptops, and cameras.

A list of the HDMI ports available on the product, each entry indicating the number of ports and their specific HDMI version or additional features (e.g., "2 x HDMI 2.0b", "1 x HDMI 1.4 with CEC"). This attribute helps users understand both the quantity and capabilities of the HDMI connections.

The diagonal measurement of the image sensor in a camera or imaging device, expressed in inches or millimeters. It indicates the overall active area available for capturing light and is commonly used to compare sensor sizes such as 1/2.3", 1/1.7", APS‑C, Full‑Frame, etc.

The highest number of frames per second that a device can capture, record or display, expressed in frames per second (fps) or hertz (Hz). It indicates the maximum motion smoothness and recording capability available for video or gameplay.

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 multiplier that indicates how many times an image or field of view is enlarged by the optical system of a camera, lens or other imaging device. The value is expressed as a plain number with an optional "x" suffix (e.g., 2x, 5x). It represents the ratio between the magnified and the original size and does not include digital zoom effects.

The method or combination of methods used to secure a device or system with a password, such as requiring a password on boot, during user login, or for supervisor access. It indicates which security steps are enabled and can be listed separately.

Indicates whether a camera or video device supports Pan‑Tilt‑Zoom (PTZ) functionality, allowing the operator to remotely move and zoom the view horizontally, vertically, and magnify the image.

Indicates whether the product is manufactured in accordance with the RoHS (Restriction of Hazardous Substances) directive, which limits the use of certain hazardous materials in electrical and electronic equipment.

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.

Indicates whether the product comes with a built‑in speaker included in the package. A value of "Yes" means a speaker is supplied, while "No" indicates that no speaker is provided and must be purchased separately.

Represents the count of external USB 2.0 (high‑speed) connectors available on a device. The value is an integer indicating how many USB 2.0 ports can be used for data transfer or power delivery from the outside of the product, regardless of internal placement or version.

The type(s) of USB connector(s) present on a device, such as Micro‑USB, USB Type‑C, USB Type‑A, or combinations thereof. This attribute indicates the physical ports that can be used for data transfer, charging, or peripheral connectivity.

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.

A list of the audio codecs that a product can use for transmitting or recording voice signals, such as G.711, AMR‑NB, Opus, etc. Each value represents a valid codec supported by the device’s hardware or software.
