EZVIZ Peephole Camera with 4.3" Colour Screen Display

A list of the audio codecs, channel configurations, and related technologies that a product can play or output. Each value may combine a codec name (e.g., Dolby Digital, DTS‑HD), a channel count (e.g., 5.1, 7.1), and optional qualifiers such as "High Definition" or "Virtual Surround" to describe the exact audio capability of the device.

A colour is a visual attribute that describes the hue or shade of an object or surface. It can be a single dominant colour, a combination of colours, or a range such as "Black, White". The value may be expressed in common names (e.g., Black, Silver) or descriptive terms (e.g., One Colour, Assorted).
