Thinking of fitting one of these so that I can take care of important, but frustratingly difficult to schedule, deliveries, i.e. send them to a truste d neighbour (having wasted whole half days just waiting in!) and also to fi lter out time wasters who are 'conducting a survey' etc etc.
I'm thinking specifically of one which uses an smartphone app so that I can be online anywhere in the world but can talk to the caller and similarly s o can SWMBO aswell on her smartphone.
Also seems a great way of deterring speculative burglars and other undesria bles like trick or treaters.
Has anyone a model or system they can recommend?
