Magnetic Alarm Switches

Magnetic Switches are very crucial for ensuring the safety and security of your house. Now a days many people prefer to have this modern technology tool so that they can sleep in peace. These switches work on magnetic fields concept. Used in the doors and windows they get into motion whenever a magnetic field is broken by opening doors. It comes in three types of surface mounted, recessed contact and roller contract. Whenever one plays wrong with your doors the magnetic switch will set off the alarm bell. Used in conjunction with doors and windows, magnetic switches work on the principle of circuit breaking. Technically speaking the moving parts of the magnetic switch is fixed with magnets whereas fixed frames have sensors installed upon them

Magnetic switches are categorized into two segments of relay switches and solenoid coil switches. Both have different design but operate in almost similar way. These magnetic alarm switches are connected in a loop that consists of magnets and electronic contact switches. Whenever someone tries to barge through your door or window, the already closed circuit cuts the circuit which triggers alarm.

Surface mounted switches can be seen with naked eyes can be comprehended from its name. They are available in different sizes and 2-3 colors. You do the choice of painting them according to your door color. Recessed contact switches work in the same way as of surface mounted. However it is recommended to fit them during the construction phase itself. Roller ball contact magnetic switches are also known as overhead mounted magnetic switches. Most of these magnetic switches have a life span of 2-3 years.

Keyless Door Locks

Your house is one place that you always want to keep secured. Right from sensors to alarm bells and fire alarms etc, we people prefer to take care of our houses in best way possible. Modern technology has also been quite useful in providing us best of security facilities and options. One thing where the advent of modern technology has done wonders is locks. Currently many people prefer to have keyless door locks. This trend is more popular in urban parts. Not only houses but offices and buildings also are seeing flurry of keyless locks.

A keyless lock is basically a type of lock where one does not need to use any keys to open and close the door. It uses an entirely different method for opening and closing purpose. Opting for keyless door locks is very much conditioned to your budget. Before going for these locks make sure to analyze your budgets. If you are looking at the option with small budget then go for just one lock. It could be external lock. You can also choose to ignore the keyless interior door locks because that is going to cost your dear. But if in case, budget is no constraint then go for keyless locks all over the house.

The keyless locks don’t require keys for opening the door. It uses a different method of code or magnetic card system. You can use different code combinations. From safety point of view you can trust the durability of these locks as they are known to survive rough weather and other unfriendly elements of nature. Keyless locks are available in different price range. One can choose as per his budget and likeness for the product.

Sensor for Home Security System

Sensor is a very popular electronic device used in home security system. The prime function of sensor is to sense an object and also signal as well. Factors like pressure, temperature, light intensity and sound etc are sensed and measured by this device. This new electronic device has started to make a continued presence in many houses and corporate offices. The technology is such that, door sensors even use microwave rays and infrared to identify and observe movements near doors.

The prime functions involved with sensors are that of, sensing, communication and calculation. All these operations are done using security system in wire as well as wireless forms. There are several sensors like, infrared sensor, capacitive, piezo electric sensor and optical sensor. The sensor works using photoelectric detector. The most popular sensor is normally commercial wireless door sensor that is quite apt at detecting sound, intrusion of any kind and even natural elements like heat, air waves and other elements. One can choose sensors as per his needs and location of the home/office. The lifestyle and fire alert sensors are also crucial factors while deciding upon door sensors.

Sensor does not work in isolation. To complete its operations it has been attached with burglar alarm, camera, siren, smoke detector etc. One can either go for sensors that use infrared or microwaves or can opt for hard wired security system. The later option is more expensive because of the costs associated with using wires and installation charges.
