1. Resolution Defined
Resolution in video surveillance refers to the number of pixels a camera can display, typically measured as width x height. 2K resolution, also known as Quad High Definition (QHD), offers a pixel count of 2560×1440. In contrast, 1080p resolution, or Full HD (FHD), delivers 1920×1080 pixels. This difference in pixel count directly impacts the level of detail each resolution can capture.
- 2K resolution provides approximately 78% more pixels than 1080p, resulting in crisper, more detailed images.
- 1080p resolution is sufficient for general home surveillance but may fall short in scenarios where high-detail imaging is essential.
2. Image Quality Comparison
When comparing image quality, the higher pixel count of 2K cameras means that images are sharper and clearer. For example, in a scenario where a camera is capturing a person’s face, 2K cameras can retain detail even when zooming in, whereas 1080p images may start to blur.
