An 8MP camera or recorder captures ultra-clear footage with about 8 million pixels per frame—roughly 3840 × 2160 pixels. That’s what most people recognize as 4K Ultra HD.

For home security, this means you’ll get sharp, detailed video that can capture critical visuals like license plates or facial features. You can also zoom in without losing clarity, and since each frame contains more information, fewer cameras are needed to cover large areas efficiently.
