Range of CCTV Camera Megapixels explained

13th November 2019

Camera resolution is defined as the amount of detail that a CCTV camera can capture. Resolution is measured in pixels. A higher number of pixels means more detail and larger images without blur or being grainy. Resolutions In CCTV cameras are often measured in Megapixels, which is just over one million pixels, 1,048,576 to be exact.

Megapixels Resolution
2MP 1920 x 1080
4MP 2560 x 1440
6MP 3072 x 2048
8MP 3840 x 2160

A good rule of thumb is to have enough resolution where it is required, not automatically upgrade your CCTV cameras to the highest resolution simply because they are available.

For number plates and faces
If you want to capture number plates and recognise people’s faces, buy at least 2-megapixel CCTV cameras — based on our experience. A 1080p Full HD IP CCTV is able to identify number plates and faces within 10metres in daylight.

Covering wide areas of property
Higher resolution means greater coverage and fewer cameras needed to monitor your property.

If you want to monitor a wide range of your property, such as your farm, barn or yard, buy at least 4MP IP security cameras (systems). One of the most compelling advantages of 4mp and higher megapixel IP cameras is the combination of situation awareness and image details, which allows you to view wider areas and see more image details.

Frame Rates
Typically, frame rates of CCTV cameras are around 25FPS (frames per second). This means smooth video and also helps to keep the file size lower on the DVR hard drive.
