Good locks on all outside and first floor windows are essential to a home’s security and will go a long way toward discouraging burglars. But an added protective device that is increasingly being used in homes is the burglar system, which sounds a loud bell, horn, or siren (警报器) when someone tries to break in. Although this will not always prevent entry by a determined professional burglar, it is often enough to scare off vandals (故意破坏他人财物者) and spurn-of-the- moment thieves who account for a high percentage of residential break-ins.
Security alarm systems have been available for many years and have long been common in commercial and industrial establishments and in large homes. But until the last few years, these systems were almost always professionally installed because they required complicated wiring techniques, individualized design, and sometimes lots of carpentry, all of which made them expensive.
To answer the demand for low-cost alarm system
A. security alarm systems can only be installed in commercial and industrial establishments and in large homes
B. security alarm systems are still very expensive
C. now, people can buy low-cost security alarm systems and install themselves
D. security alarm systems can't scare off vandals
