A Home or Business security system is like a key to help protect your home or business from intruders and burglars. Today’s security systems are increasingly popular and intelligent, and these are being installed in most homes.
We do have many different models that are available from wired systems to wireless systems. Or you can purchase the “do it yourself” alarm systems and these will range in price from $10 to $100, but for a more sophisticated or a whole home security alarm system, you will need to call in the experts to get a better idea what they can do and get the price ranges too.
Most security systems are built around a fundamental design concept and these concepts mostly use simple electric circuits. These circuits are built into an entry or doorway and once the circuit is broken the alarm system is triggered.
Closed or Open Circuits
Normally, two types of circuits are mostly used in this kind of system. They are either closed-circuit systems or open-circuit systems.
Closed circuits are seen as the better choice, as these are monitored continuously and any intrusion is immediately detected and owners alerted.
Closed-circuit systems use “magnetic sensors” and when a door is closed, the magnet that is embedded in the door comes in contact with an electric sensor in the door frame which closes the circuit the alarm is activated and it is armed now. When an intruder opens the door, the system detects this circuit is opened but the intruder does not know that he has opened the circuit. In sophisticated systems, a CCD camera may be activated and start to record the intruder.
The Open circuit method simply uses small buttons that are embedded into the door frames and these buttons are “depressed” when a door closes. If the door is opened the button is released and this will trigger the alarm.
The “control system” is the most important item of the equipment that is, used in security systems and these control systems are normally located just next to the inside of your main entrance or door.
Once your alarm system is triggered you must enter your security code into the control system to disable the alarm or it might activate the security or the local police station.
The control system is also used to turn “ON” your alarm system when you are about to leave your home and this is crucial to any security alarm system.
Let us give you here a rundown of the key components of any security alarm system; sensors or circuit breakers of a control system. In some cases, there might be many more additional components that can be used and these include things like “motion detectors”. These can be installed within your home for better security purposes.
Other systems employ special “face recognition” software and that too can be used in conjunction with the other security systems to enhance your home or business security better.
Whatever type of alarm system you decide to have installed in your home or business, it is always advisable to shop around before purchasing anything.
