Bizarrely we had a takeover recently where the customer was told by the Police that they were removing Police response from the company that they were with for telling people exactly that. The Police had contacted SSAIB and everything apparently. I personally would not rely on self monitoring, the amount of times a day I miss calls because I have left my phone in my car, office, workshop, store room. If I am in a meeting my phone is off, there are plenty of places I go where I have no signal. Much better to have a monitoring station dealing with my alarm problems
