The door and window sensors are a key piece in any home security system. It must be taken into account that a high percentage of thefts suffered in homes and businesses originate from the entrance door, a secondary door or even a window.
Without a doubt, the access points of a home or business are the most vulnerable in terms of security and, therefore,The door sensor is becoming an essential element for home protection.
A good alarm system will always have, therefore, several sensors on doors and windows to keep track of any unexpected opening.
These are nothing more than security devices that notify when a door is opened.The same would happen if we installed it in a window. This way you can know, wherever you are, when someone enters or leaves the home. In addition, they are an element that allows you to control all the passage areas.
The sensor, thus, in addition to protection,offers you informationincorporated into home automation. Themagnetic sensors for sliding doors, for entrance doors or for any other access to the home, have the same operation.
Do you want to know how they work and how to install? Keep reading.
How to install a door sensor?
Un good security system has a door sensor. Thanks to this magnetic detector you can have control and supervision of any entrance or exit to your home or business, so that in the event of possible unwanted access the alarms will be activated.
But,how to install a door sensor?Whether for the main door, a secondary door or a window, the installation is the same.
The ideal, in fact, would be to install a sensor for each vulnerable access to the home, whether all the accesses or, for example, the accesses to the ground floor in a large house with several floors.
Un magnetic sensor to install on a door or window is always made up of two elements:a piece intended for the immobile part of the door (or window) and a second piece that is placed on the mobile part of the access –through adhesives or screws–. Thus, we will place one part in the door frame and the other on the door itself.
It is important that we fix the two parts of the sensor perfectly aligned. Failure to do so could make it difficult or impossible its correct operation .
On a sliding door, install the sensor in an upper corner, in the same way as on a folding door, in the upper corner opposite the hinges.
In this way, we will haveready to install a magnetic sensor: both elements will be located a few millimeters from each other when the door is closed and will allow the technology to warn when there is some distance between them: in that case, someone would be opening the door!
Let's see how it works in detail.
How does a magnetic door sensor work?
Magnetic door sensors are one of the most effective elements in security systems and home or business alarm .
However, they are also one of the simplest mechanisms: their operation is really simple, perhaps that is why they are even more attractive to install in the home.
T They have a very simple mechanism: They are made up of two magnetic contacts, the two pieces we talked about before, so that they form a circuit with each other. Thus, when the door opens, the circuit and contact between both pieces are broken, which sets off the alarms.
A door sensor, therefore,It not only features quick and easy installation but also simple operation. When the circuit is interrupted due to the separation of the two parts of the door or window, or due to the breakage or vibration of the parts, the alarm is activated.
Thenthe security protocol is automatically launched. In this way, as long as you have the sensors connected, the system will notify you of any opening or attempted opening, forcing the door or strong or sudden movements that could be an indication of theft.
La door alarm notifies the ownerof an anomaly in real time through a notification on the mobile phone and, if the home security system is connected to a AVE , as always happens when you install a level 2 or higher alarm system, will notify the central office of the event.
Likewise, in the event of an attempted break-in or forcing the door,The wireless detector will activate the alarm siren, which can deter theft. You can always check remotely whether the doors or windows that have the magnetic sensor installed are open or closed.
Have you ever left home and then had doubts about whether you had closed the door properly?
What types of door sensors exist?
There are several types of magnetic door sensors. Candistinguish between wireless and wired. In the first case, they usually have an IP connection and are therefore connected to the Internet, in the same way that they can connect to home automation.
For their part, wired devices have a more complex structure, since they must be integrated through cables.to a home alarm system and are usually cheaper,However, their installation requires more time, effort and money than that of wireless sensors (whose energy source comes from batteries).
On the other hand, you may encountermagnetic door sensors, which work through a magnet—establishes the connection between the two parts or pieces of the sensor— or sensors whose operation depends on a light beam or infrared . One of the pieces generates the light and the other receives it, so that when you open the door this light circuit is broken.
In addition to the sensors,door alarm elements include a control panel–which controls the system and saves the movement sequences and includes an alarm transmitter– and a keyboard to activate or deactivate the alarm.
As you can see, the world of door sensors is very extensive. In the end it doesn't matter what device you choose or how you install it; all technology will help you to reinforce home security to prevent theft.
