“I think it would be a good idea , if we are told that when the phone rings SO does. The alarm, I was quite disturbed at first, thought I had done something wrong!! Also I felt it would have been good to know a little of how it works, I was not sure, so of course I had to shout from my living room and hoped they heard me(which they did) when I tested it, just me ,I expect but it may help someone else! Otherwise I think it is brilliant and makes me (and my family!) feel secure.
Thanks. Pam”
