Security Camera Resolution Explained: 1080p vs. 2K vs. 4K

Resolution is the number everyone fixates on, but it's widely misunderstood. More megapixels can mean sharper footage — or just bigger files that strain your storage. Here's what matters.

The basics

• 1080p (2MP): fine for small areas and tight shots like a doorway.
• 2K (4MP): a noticeable step up; a strong all-rounder for most homes.
• 4K (8MP): excellent detail over wide areas — driveways, yards, parking lots.

Why higher isn't always better

4K captures more detail but uses far more storage and bandwidth, and needs good lenses and lighting to shine. A well-lit 2K camera often beats a poorly-lit 4K one.

How to choose

Match resolution to coverage area: tighter shots can use less, wide areas benefit from more. Plan storage to match. The right answer is usually a mix across your property.

We size each camera to its job so you get the detail you need without overpaying for storage.
