What is the different between SONAR & IPS

Hi, im reading about each feature of SEP to get comprehensive understanding, but i am a little bit confuse about (SONAR vs IPS)

from my reading it seem they do the same things, both of them are Behavior-Based Protection.

Can you please descrip the different between them with example if possible?

I was watching the learing videos of SEPM 14, they sapareted the SONAR and IPS in deferent layer

can we say:

SONAR is application behavior protection & IPS is network behavior protection?
