Door camera selection?

Hi,

I apologise for the many questions. I'm nearly there now.

I've been very happy with my 4mm mini bullets that are now positioned round my house. Thankyou for the great service from Use-IP. Very happy with my purchases.

Now I'm looking at the front porch and door to cover people coming to the house.

I remember being recommended one of these: Hikvision DS-2CD2545FWD-I


Just out of curiosity, is there a higher megapixel version or is this not as important for a close up door camera...
