For safety

I always see to it my safety at home special when some people I don’t know just knock on our house door. I wish to have a camera or spy gadgets on my door bell to see first the one who is at my door before opening it. With this everyday dilemma, I encounter at home I just don’t open our door unless they are my visitors who have called me up first to inform me they are coming. Another safety precaution, I always have my telephone with me and if someone called up and I am not familiar with their telephone numbers, or their numbers are not registered in my phone I don’t answer their calls. Nowadays we should really be aware of our own safety and I hope we can have still a peaceful world to live in.
