Intruder Alarm - A Review
Alarm systems are traditionally equipped premises for many years and are now a growing demand for private homes and gardens as well. If you've ever shopped for a home security system, then you know there are a bewildering variety of options available. These systems range from inexpensive and easy to install alarm systems for sophisticated and complex network security, which must be installed byProfessionals. But as it turns out that most alarm systems actually built around the same basic design concepts, so it is really necessary to spend a lot of money?
Please take a look at the information below and find out some details of the alarm system components. As will be seen, some of the most effective intruder alarm systems, the simplest, easiest to adapt, and less expensive.
Wireless Network Detector
The magnetic switch
The simplest alarm works with a simple circuitembedded in a door or window. In a circuit, current flows only when the path between two points of opposite charge. To connect or disconnect the electricity to open or close a part of the circuit.
The activation of an alarm system if you turn the switch opens or closes the circuit, such as opening a door or window recognizes. The most popular form of this alarm system is a closed-loop system.
In a closed circulatory system, the electricCircuit is completed when the door is closed. This means that until the door closed, electricity can flow from one end of the circuit to another. But if someone opens the door, the circuit is open and current can not flow. This triggers an alarm.
The magnetic sensor as standard in most circuits consists of a simple switching device consisting of a battery powering a circuit, a spring-driven metal switch built into a door frame and a magnet in the door, which is alignedwith the switch.
While the door in the closed position, the magnet attracts the metal switch closed and the circuit is complete. When the door open magnetic spring switch in the open position, cutting the current that triggers the alarm.
You can also adjust this option in a window frame. If an intruder opens the window, the system in exactly the same way the door is operated.
The best alarm systems include a control boxto prevent the intruder the door or window, then reconnect the circuit and disable the alarm. The unit has its own power supply and control circuit and triggers the alarm when the switch is open, but can be turned off when someone in a security code on the keyboard box.
The PIR motion detector
The alarm circuit magnetic circuit described above is ideal for protecting doors and windows of a house,but not always sufficient all-round protection. The best protection for additional motion detectors, which are often referred to as PIR is in good shape.
Passive infrared (PIR) motion detectors are used in most modern and even in some of the basic security settings. These sensors monitor the heat of the body and if an intruder comes into view of the PIR, recognizes the increasing heat of the body and triggers an alarm should be activated.
PIR motion detectors are set tothat the box does not alarm them instantly recognizable beat, the body heat. There is a delay of several seconds that the time to get into home ownership and key in the security code to unlock the system.
One might ask if you can see the movement if you look out through a window. It is not possible, because the glass is not transparent to infrared energy.
Alarm activated
Depending on the type of alarm system installed there may be moreDeterrent to an intruder. In advanced systems, the check box to be connected to various components and is usually to activate a sound alarm siren or loud external siren and a flashing light and a telephone auto-dialers. The siren and lights alert the landlord or neighbors that someone broke into the house and the sound often lead the attacker to flee in haste. The telephone auto-dialers can use a pre-recorded message with the address of the house and canby phone or office phone, a neighbor or someone else who can help.
Wired or wireless?
This is as easy as it seems, means wired burglar alarm systems that connects all the components must be connected together to complete the circuit. However, there is so much easier to install, wireless systems automatically transmit signals between all components of the alarm system to avoid time-consuming and sometimesunpleasant process wiring.
No telephone line or electricity?
GSM burglar alarm systems are affordable vacation homes, boats, caravans or any protection, which connected the phone line and can not work without electricity. These systems are easy to assemble, and similar components to other systems, including sirens to scare off intruders, but also a built-in SIM card and battery automatic dialing you fromWireless network when enabled.
What is the best burglar alarm system?
Basic components are similar in most alarm systems, if they are complicated and expensive alarm systems or simple and easy to install alarm systems. The options and possibilities are vast, but often the choice for a wireless system for a house to protect the office, store room / garage, garden ornaments, holiday home, caravan / car / boat. Wireless alarm systems can be veryEconomic to purchase and are always much easier to install and above all have the same basic components as the most advanced and expensive systems built.
