If you’re looking for a security camera, you might be wondering how many megapixels you need. 5 megapixels is a good option for most people. It’s high enough resolution to get clear images, but it’s not so high that it’s expensive.
Most security cameras have between 2 and 8 megapixels. 5 megapixels falls in the middle of that range, so it is a good resolution for a security camera. The higher the megapixel count, the better the image quality will be. However, megapixels are not the only factor that determines image quality. The quality of the lens and sensor also play a role.
