Screen Resolution

Screen resolution refers to the number of pixels displayed horizontally and vertically on the screen, typically expressed as "width × height" (e.g., 480×360). In body cameras, resolution determines the clarity of on-screen visuals, directly affecting the user's experience during video preview, playback, and menu navigation.

1. Common Resolution Specifications (for Small-Size Screens)

Resolution	Pixel Density	Application Level
160×128	Low	Basic monochrome status screen or icon display
320×240 (QVGA)	Entry-level	Color status screen, basic preview and playback
480×360	Practical	Common in 2.0–2.4 inch LCDs, improved clarity
640×480 (VGA)	Moderate	Offers clearer previews, supports simple GUI
800×480 (WVGA)	High Definition	Suitable for touchscreens and graphical interfaces
960×540 / 1024×600	HD+	Used in high-end touch-enabled devices for better detail rendering

2. Resolution and User Experience

Display Clarity: Higher resolution provides sharper and more detailed images, which is crucial when reviewing evidence footage or checking scene details.
Information Capacity: High-resolution screens can display more icons and data simultaneously, improving operational efficiency and UI aesthetics.
Screen Size Matching: Resolution must match the physical size of the screen to ensure optimal visual quality, avoiding blurred text or improperly scaled icons.

3. Shelleyes Application Reference

320×240 / 480×360: Commonly used in models with ~2.0-inch displays, balancing cost and clarity. Typical in S7 and S3.

640×480 : Suitable for body cameras requiring higher playback clarity or touch interaction.

Higher Resolutions: Used in high-end models such as the S9, ideal for graphical interfaces, touch interaction, and split-screen functionality.
