Oh! This is just what we need at home and specially around the neighbourhood. With the fast rate of increase in crimes and robbery which may be attributed to poverty and recession, bad elements are just around the corner preying around innocent victims. Installation of a safety equipment at home or in the office is a must to prevent unlikely events which may lead to great loss of properties and lives in the gravest sense. Personally speaking, I will not have second thoughts on spending a few dollars in exchange for my family’s safety. Don’t you think so?
