Understanding how a wireless security system works

Making a home secure is easy with the help of modern technology. You can install a wireless security system and monitor from distance or from within your home. An alarm will ring when someone will violate your privacy. At the same time, security system will send a signal to a monitoring company who will take necessary action. To make sure that your home is secure, you should spend some time and learn how security systems work.

A wireless security system has become standard equipment in homes and offices. It sounds a buzzer and sends a signal to a central monitoring system when it detects motion. If you have shopped for security alarms, you already know that there are many options available in the market. Majority of wireless security system products come with basic alarms. You can find cheap DIY alarm kits as well as professional alarms that come with central monitoring system. The options are various and you can choose one depending on your budget and your requirements.

To make sure that your wireless security system always works perfect, you should spend some time learning how a basic alarm system actually works and how it connects to the wireless security system. This will not just help you improve reliability of your security alarm but knowing how different alarm systems work can be helpful when selecting an alarm system for your home.

How an alarm system works

The most basic security alarm system uses a simple electric circuit which is disconnected when there is a push on the magnetic sensor. The magnetic sensor sits next to the switch and keeps in pressed so that the current continues to flow. In case someone pushes on the door, the magnetic sensor moves away releasing the switch which ultimately breaks the circuit and the alarm start buzzing.

Some alarm systems that come with a modern wireless security system use an open-circuit system. As opposed to a closed-circuit wireless alarm system (the one discussed above), open-circuit is disconnected (or open) when the door is closed. As soon as someone opens the door or pushes it, the magnetic sensor slides down and completes the circuit. This type of alarm goes off as soon as the circuit is complete and the current starts flowing in the circuit and a signal is sent to monitoring agency through a wireless security system.

Some burglar alarm systems use a simple button as a switch. If force is exerted on the button, it completes the circuit and the alarm goes off. This switch can be installed in a way so that opening the door pushes the switch.

Where does a control box come in?

Since majority of security alarms and wireless security system products use a control box, you’d want to know what role it will play to keep you protected from incidents of burglary. A control box is basically a central unit of any wireless alarm system. It is connected to the alarm systems wirelessly and provides an interface for turning the alarm off and doing some other administrative tasks such as changing the alarm password etc. The control box coupled with a wireless security system ensures that burglar won’t turn off the alarm by completing/breaking the circuit (depending on the design of alarm circuit) but instead the alarm is always to be turned off from the control box. This control box can be installed in a safe place away from the entry points. Since it will be wireless in case of wireless alarm system, you won’t have to take the wires through your home. Anyone trying to switch off the alarm or disable it by cutting wires will never find the control box. The control box uses its own power supply, independent from supply used by wireless alarm system so even if the power is cut, the central system will still be functioning along with wireless security system.
