Connectivity and motion/person settings

Hey guys i have two questions.

1st : I have some spotty areas in the house where the wifi wasnt so great and installed a wifi extender. Will my cameras automatically connect via the extender ? Does wyze make a product like an extender?

2nd : my cameras are set up to record continuously but also send alerts/notifications for person and motion (its my understanding that mition need to be on to record under the person service)
It seems to mostly record cars. Not people

1st - it should, I’m running several cams that depend on my wifi extender.
