When it comes to choosing a camera system, one important consideration is the resolution.  The resolution of a camera is measured in megapixels (MP) and the higher the number of megapixels, the higher the image quality.

These are three popular resolutions for home security cameras: 2MP, 4MP/5MP, and 8MP.

Below, I'll explain the pros and cons of each to try and help you decide which one is right for you.

2MP Camera System:

A 2MP camera system is a basic system that captures 1080p resolution video footage.  It's a good option if you're looking for a budget-friendly system that provides basic coverage.  With 2MP, you'll be able to see people and objects, but the video quality won't be as clear and sharp as with higher resolution systems.


  • Good image quality for basic surveillance needs

  • Affordable price


  • Limited details in the footage, especially when zooming in

  • Difficult to identify people or objects in the distance


4MP/5MP Camera System:

A 4MP camera system captures 1440p resolution footage, which is a significant improvement over the 2MP system.  The video quality is sharper, and you'll be able to see more details in your footage.  This system is a good choice if you're looking for a higher level of security and want to capture more detail in your footage.


  • Improved image quality compared to 2MP

  • Able to capture more details, including faces and license plates

  • Good balance between image quality and price


  • More expensive than a 2MP system


8MP Camera System:

An 8MP camera system is the best option for those who want the highest quality surveillance footage.  It captures 4K resolution video, which is 4 times the resolution of a 1080p camera.  With an 8MP system, you'll be able to see every detail of your footage, including license plates and facial features.  This system is ideal for those who want the most comprehensive security coverage for their home.


  • Highest image quality, capable of capturing the most details

  • Superior image clarity, especially when zooming in

  • Excellent for large areas or long distances


  • The most expensive option

Now, if you are wondering if a 8MP camera system is worth the investment? The answer is simple:

It provides the best image quality, which means you will capture more details, especially in large areas or long distances. With an 8MP camera system you'll be able to see everything that's happening on your property in crystal-clear detail which is essential for identifying potential threats or suspicious activity.


Overall, an 8MP camera system is the best choice for those who want the highest level of security and surveillance for their home. Although it may be more expensive than the other options, it is definitely worth the investment for your safety and peace of mind.
