DOOR AND WINDOW CONTACTS: These are a common part of most modern alarm systems. The purpose of it is to determine whether a door or window is currently left open unintentionally. The device will send a signal to the alarm system in such an event and it will set off making the house owner or the monitoring team aware of the situation.
Security systems that protect a home have surely come a long way from locks and barred windows. Modern technology has made these devices surprisingly sophisticated. Luckily, this sophistication is not reflected too much in their price: affordable prices, in the range of a couple hundred dollars, made these devices relatively common in modern homes.
- According to a Board Resolution passed by the International Association of Chiefs of Police in 1994, alarm systems, providing, though, they are professionally installed and monitored, are useful instruments to deter crime and provide peace of mind for both residential users and business owners.
