Anyone got a panic button

Hiya

I wondered if anyone had a panic button.

I know there on the key fobs and keypad but I am more thinking about the standalone button and its general point.   Note I am in UK.

I asked simplisafe what would happen if i purchased one and pressed it and I got this response back :

"The Panic Button instantly triggers an alert to Securitas after being held down for 2 seconds and sets your alarm off."

"Visual representation is required for a Police Dispatch, if there is no contact via the numbers provided, Securitas will try again in 15 minutes and if there is still no contact, a Guard will be dispatched."

"You are able to set the Panic Button to a silent alarm so if you did press it in silent mode, an alert would be sent to Securitas and if they do get Visual representation of an intruder or break in, the police will be dispatched."

So I suppose my point is if its a PANIC button... and I press it... I suppose if I am in bedroom and there is no visual verification as no camera present and I cant answer the phone nothing basically happens for 15 minutes - then it happens again.... then a guard gets dispatched so the PANIC button would take probably an hour for someone to actually come round to see what was going on and even then... it would be pretty pointless.

I suppose it would work ok if something happened downstairs but thats about it or am I missing the point!
