Do I Need 4K CCTV for a Home, Shop or Warehouse?

Most homes do not need 4K (8MP) on every camera, 6MP is enough for general coverage, but 4K is worth it on any camera covering a driveway, entry or till where identifying a face or number plate matters. Shops need it at the till and entry. Warehouses need it on the perimeter and loading dock, not every internal aisle camera.

Where does resolution actually matter?

Resolution only matters where you need to zoom in after the fact and still identify detail, a face, a number plate, a product being concealed. A wide overview shot of an empty car park does not need the same resolution as a till camera capturing hands and a drawer.

Is 4K overkill for most positions?

Yes, for general perimeter and overview coverage. 6MP already exceeds what most people ever review footage at, and higher resolution increases storage consumption without adding useful detail on a position where nobody needs to read fine text or a plate.

Resolution by use case

Real product check

For positions that warrant genuine 4K, the Dahua 8MP (4K) Camera Kit and Uniview 8MP 4K Dual-Light Dome Camera both deliver genuine 3840×2160 resolution suited to driveways, tills and loading docks. For everything else, a 6MP kit like the HiLook Pro Series covers general positions without paying for resolution you will not use.

FAQ

Does 4K use noticeably more storage than 6MP? 

Yes, roughly 30–40% more per camera at the same frame rate, which is worth factoring into NVR hard drive sizing if mixing resolutions across a system.
