4MP Security Cameras

The new mainstream standard. 4MP (2K/Super HD) security cameras deliver twice the detail of 1080p, making them ideal for capturing faces, number plates, and fine details. The most popular resolution for serious security applications.

Security Cameras Australia stocks 4MP cameras from Hikvision, HiLook, Axis, Hanwha, and other leading brands.

Key Features of 4MP Cameras

  • 2560 x 1440 resolution (2K/Super HD)
  • Double the pixels of 1080p
  • Excellent digital zoom capability
  • Sharp facial detail at medium range
  • Reasonable storage requirements
  • Widely available across all brands

Why Choose 4MP Cameras?

4MP has become the go-to resolution for security professionals. Twice the detail of 1080p means clearer faces, readable text, and better evidence quality. Modern H.265+ compression keeps file sizes manageable. The best balance of image quality, storage efficiency, and cost for most applications.

4MP vs 2MP vs 8MP

4MP provides a significant, visible improvement over 2MP without the storage penalty of 8MP. For most installations, 4MP is the sweet spot. Choose 2MP for maximum economy or basic monitoring; choose 8MP when you need to identify faces from greater distances or want future-proof resolution.

Popular Applications

4MP cameras suit residential front doors, retail shops, office reception, car parks, and any application where clear identification matters. The default recommendation for most home and business installations.

How does 4MP compare to 4K cameras?

Can 4MP cameras identify faces?

Yes, 4MP cameras capture enough detail for reliable facial identification at ranges up to 10-15 metres depending on lens and scene conditions.

Should I choose 4MP or 8MP cameras?

4MP for most locations, 8MP for entry points, cash registers, or anywhere positive identification is critical. Many systems mix both to balance quality and storage.
