what would cause an alarm type sound under the hood when, key turned, wont start on 1996 Toyota Camry

the car has no alarm system. lights radio etc. are working
this just happened first time today. never heard a sound like that before. sounds like the buzz is located under the hood between the wind shield wipers bizzare.

Starter motor is at that approx location. Possible weak battery, poor connecions or failing starter motor.
