Police dispatch - UK

In UK simplisafe have opted for visual verification.

This is something that I've questioned for a while...

Why cant it be if two sensors are triggered....

What happens if wifi goes off ... yes cellular kicks in but that wont help when cameras run of wifi....

Would be great if simplisafe brought put the 2 triggers or visual rather than someone calling me if no visual... telling me things are triggering.... what so I want to do.... do I get the option for them to call police or would it be a guard .... which would be pointless.
