EZVIZ 3MP Wireless Doorbell Kit

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

The chemical composition or classification of a battery, such as lithium‑ion, lithium‑polymer, nickel‑metal hydride, sealed lead acid, alkaline, zinc‑air, etc. It indicates the type of electrochemical reaction that stores and delivers energy in the device.

The chemical composition or classification of a battery, such as alkaline, lithium‑ion, NiMH, or lead‑acid. It indicates the energy storage technology used in the product and helps users identify compatibility with devices that require specific battery chemistries.

The maximum frequency at which a wireless channel can transmit data, expressed in hertz (Hz). It represents the bandwidth capability of the radio interface and is used to compare performance across similar devices.

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.

List of the memory card types that a device can read or write, such as MicroSD (TransFlash), SD, MMC, CompactFlash, and others. Each value represents a format that the device’s slot or reader supports for storage expansion.

The country where the product was manufactured or its primary geographic source. This attribute indicates the nation responsible for the production or assembly of the item.

The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.

The span of frequencies, expressed in hertz (Hz), that a device can operate within or respond to. It may be given as a single value, a numeric range (e.g., "20 000‑50 000 Hz"), or an open‑ended interval such as "2.4 GHz+" indicating the lower bound only.

The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.

Indica el material o la combinación de materiales con los que está fabricado el componente más importante de un producto, como metal, plástico, vidrio u otros compuestos. Este atributo ayuda a comprender la durabilidad, peso y estética del artículo.

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.

The largest capacity of a removable memory card that the device can support, expressed as a digital storage size (e.g., megabytes or gigabytes). It indicates the maximum amount of data that can be stored on an inserted card and is useful for comparing devices with different card slot capabilities.

The total count of battery cells that the product can accommodate or use. The value may be a simple integer (e.g., "4") or include the type of battery (e.g., "2x AAA"). It indicates how many individual batteries are required for operation, whether they are included in the package or need to be purchased separately.

The total count of individual screws included with a product or component. It indicates how many separate screw units are provided for assembly, mounting, or securing parts, regardless of size or type.

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 physical dimensions of a camera’s image sensor, typically expressed as two measurements (width × height) with units in millimeters and inches. This attribute indicates the size of the sensor that captures light for each frame, influencing resolution, depth‑of‑field, and low‑light performance.

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

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 environmental, safety or quality certifications that a product has obtained from recognized authorities. Typical entries include RoHS, ENERGY STAR, CE, WEEE, TCO Certified, FCC, and other industry‑specific standards.

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.

A list of the wireless networking protocols and frequency bands that a device can connect to, such as 802.11a, 802.11b, 802.11g, Wi‑Fi 4 (802.11n), Wi‑Fi 5 (802.11ac) or Wi‑Fi 6 (802.11ax). The values are typically separated by commas and may include both the technical name and a consumer‑friendly label.

The horizontal measurement of a product, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.
