AVer CAM540 Black 4K PTZ Camera

Specifies the type of interface or mechanism used to secure a cable in its port, such as Kensington, Noble, IBM, or other standard lock slots. This attribute helps users identify compatibility and security features of the device.

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 the total magnification achieved by a camera or imaging device, combining both optical and digital zoom components. The value is expressed as a plain number (optionally followed by an "x" suffix, e.g., 4x or 5.6) without any unit. It indicates how many times the image or field of view is enlarged compared to its original size.

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 angular extent that a camera or optical device can capture or display, expressed in degrees. It indicates how wide the field of view is relative to the sensor or lens and helps users understand the coverage area of the device.

Specifies whether the camera’s focusing system operates automatically or requires manual adjustment. Common values include "Auto", "Manual", and combinations such as "Auto/Manual".

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 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 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.

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

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 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 main electrical supply that powers the device, such as mains electricity (AC), battery, USB power, PoE, or a combination of these options.

Represents how many RS‑232 serial communication ports are available on the product. The value is a simple integer indicating the total count of RS‑232 connectors, regardless of version or configuration.

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 minimum and maximum angles, expressed in degrees, that a monitor can be tilted or adjusted vertically while maintaining acceptable performance or usability. It indicates the tilt limits for displays such as monitors, stands, or other adjustable equipment.

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 Microsoft Windows operating system versions that the product is compatible with, including any relevant architecture or edition information.
