Base station - best location

I am just about to replace an 18 year old security system, that has just failed, with a Ring Security System. I already Have a Ring doorbell and Ring cameras so it makes sense. I own a town house so I am wondering where the best place to locate everything is. I will put the key pad in the hall where the current system keypad is and I can power it from the existing security system socket. My sensors will be in the same locations as on the current system but I am wondering where the best place to put the base station is. The options that I have thought of are: 1. I could put it downstairs in the hall where I can power it from the same socket as the keypad and mount it on the wall in a similar location to the keypad. I think that in that location it would be easily heard from outside the house if the alarm was ever activated. 2. I could put it upstairs on the first floor in the lounge where I could plug it in to an available socket and plug it directly in to my router. That means we could see and hear any notificatons on the unit (Is that important?). However I am not sure it would be as well heard outside the house if the alarm was ever activated. Where would be the best location?
