Is 3mp enough for a home camera?

Enough.

The resolution of 3MP for home cameras is usually sufficient to meet the needs of general home use. 3MP means the camera can capture images with 3 million pixels, which provides clear, detailed image quality in most situations. For common uses such as home security monitoring, pet monitoring, and baby monitoring, the 3MP resolution can provide sufficient picture clarity and detail capture capabilities. If you need higher-resolution images or have special needs, such as surveillance scenes or professional photography with very high detail requirements, you may want to consider a higher-resolution camera.
