Got a traffic ticket today. Need advice!

I got a traffic ticket this morning for failure to yield for pedestrain in a crosswalk. The fine is $165. I checked the state website and it says I will get four points on my driver's license and it will be erased after 1 year of conviction.

I did not see the pedestrain and the officer said that old lady was crossing from the other side. He also said I was drving too fast.

Should I contest? What's my best defense? I am concerned about the potential increase of insurance. Thank you for any input!
