2MP vs 4MP vs 5MP CCTV: Which Resolution?

Camera resolution is one of the most confusing parts of buying CCTV. Here is what 2MP, 4MP and 5MP actually mean in plain terms, and how much you really need.

What megapixels actually do

More megapixels (MP) means more detail in the picture. A 2MP camera records around 1080p, 4MP is roughly 1440p, and 5MP is sharper still. Higher resolution lets you zoom into recorded footage and still read a face or a number plate, instead of seeing a blurry shape. The trade-off: higher MP cameras cost a bit more and use more recording storage.

2MP: fine for general coverage

2MP is the most common choice and is perfectly good for watching a room, a gate or a shop counter. You will clearly see who came and went. Where it struggles is fine detail at a distance — reading a number plate across a wide driveway, for example, can be hard. Good budget option for most homes.

4MP and 5MP: when detail matters

If you want to identify faces and vehicle plates reliably, step up to 4MP or 5MP. The extra detail makes a real difference for entry gates, parking areas, shop billing counters and anywhere you may need footage as proof. For most homes and shops in NCR, 4MP is the sweet spot — clearly better than 2MP without the highest cost or storage demand.

Resolution is not the whole story

• Placement: a well-aimed 2MP camera beats a badly placed 5MP one.
• Lighting and night vision: good low-light performance matters as much as MP.
• Storage: higher MP needs a bigger hard disk to keep the same number of recording days.
• Camera type: for the sharpest detail and easy expansion, IP cameras are a great option.

Our simple recommendation

For general home or shop coverage, 2MP is enough. For gates, parking and billing counters where you must recognise people or plates, choose 4MP. Go to 5MP for large open areas where you need to zoom in on fine detail. Mixing resolutions across the same setup is completely fine — use higher MP only where it earns its keep.
