CCTV Resolution Selector
More megapixels only help if they land enough pixels on the target. Tell it how wide a scene one camera must cover and what you need to do — identify, recognise or detect — and it picks the smallest resolution that delivers the DORI pixel density (px/m) for the job. Planning figures; runs in your browser.
- 2 MP (1080p)320 px/m
- 4 MP427 px/m
- 5 MP480 px/m
- 8 MP (4K)640 px/m
- 12 MP667 px/m
Planning estimate only — more megapixels on a small sensor can mean worse low-light performance and bigger storage and bandwidth bills, so match resolution to the purpose rather than just buying the biggest. Confirm the choice with the product datasheet and a site test.
