8MP vs 5MP vs 4MP Security Cameras: What Resolution Do You Need?
When shopping for security cameras, one of the most important decisions is resolution. Higher resolution means clearer, more detailed footage, but it also costs more and requires more storage. Dahua offers cameras in 4MP, 5MP, and 8MP (4K) resolutions, each suited for different needs.
In this post, we’ll break down the differences between 4MP, 5MP, and 8MP cameras, their ideal use cases, and top models available at GuestCN.
What Is 4MP Resolution?
4MP (2560×1440) is 2x the resolution of 1080p (2MP). It delivers sharp, detailed footage for most home and small business applications. 4MP cameras are affordable, require less storage, and work well for general monitoring.
Best for: Home users, small businesses, and budget‑conscious buyers.

5MP (2880×1620) is 2.5x the resolution of 1080p. It delivers even more detail than 4MP, making it ideal for identifying faces, license plates, and small objects. 5MP cameras are a great balance of quality and affordability for most users.
