The total number of independent audio channels that a product can produce or receive, such as stereo (2), surround sound configurations like 5.1 or 7.2, or other multi‑channel setups. The value may be expressed as a single number, a range, or a descriptive phrase indicating the channel count.

Indicates whether a product is intended for use inside a building or structure (Yes) or in an outdoor environment (No). This attribute helps customers determine if the item meets typical indoor or outdoor requirements such as weather resistance, durability, and suitability for external conditions.

The pixel dimensions that a device can output or support for display or recording, expressed as width by height (e.g., 1920x1080). This attribute lists all the screen resolutions available on the product.

The signal‑to‑noise ratio indicates how much useful signal is present compared with background noise, expressed in decibels (dB). A higher value means clearer audio or video quality and less distortion. This attribute helps users compare devices such as cameras, microphones, or audio equipment.

The dynamic range of a device indicates the difference between its loudest and quietest audible or visual signals that can be captured or displayed. For audio equipment it is expressed in decibels (dB), while for imaging devices it may simply indicate whether high‑dynamic‑range (HDR) content is supported. The value can be a numeric dB figure or a simple "Yes"/"No" flag.
