    Thx in advance

Any Arduino will do that job.

What are you planning to switch with S2/S3/S4?

An input alarm from IP Camera

so to get to control s2 you just need to press s1 3 times or press and hold for 3 sec and then press again to quit, until u get to s2?

Yeah , press and hold 3 sec is for swtich between S2,S3,S4 in this order

anyways both scenarios possible with any arduino
