For those who are thinking of increasing
home
security , wireless sensors are the first link in DIY (Do It Yourself)
home automation
.
Next, what aspects to take into account to build a small
home security network
based on a Wi-Fi connection.
This intelligent solution allows collecting information in real time about what is happening inside the home, as well as using the simulation of
light presence
to scare away potential intruders.
The advantage of these home systems is that you can configure and program
them yourself
- they are linked to the Wi-Fi network on the 2.4 Ghz frequency - to receive alerts using
free software
such as Smart Life, Tuya Smart or Gosund.
In addition, these wireless sensors are fixed directly on doors, windows or vents.
No need to drill holes in the wall or have technical knowledge of electronics.
In addition to sensors, cameras and detectors can be added.
Being totally modular, if one requires it, new security segments can be attached.
From a touch panel, remote controls, multiple sensors,
security cameras
, alarms, doorbells and smart locks.
Advancing to the next level of complexity also implies resorting to more professional protocols such as Zigbee or Z-Wave.
With this advance one avoids the saturation of the network and also increases the protection, since they encrypt the communication.
Sensors on doors and windows
The sensors, depending on the design and their scope, are around 3,500 pesos.
Opening magnetic
detectors or sensors
represent the first security element of a complete alarm system.
They are elementary and very discreet pieces, capable of notifying about any intrusion.
The function of these electronic devices is to supervise the closing and opening of doors and windows or any other element that controls the entrance to the different areas of a property.
The detectors are composed of two magnetized parts: one that is mounted on the frame and the other, adheres or screws on the moving part.
These magnetized poles are in contact at all times.
Therefore, when opened unexpectedly, the electronic components detect that this link has been lost and can trigger the
alarm signal
.
The price of these sensors, depending on the design and its scope, is around
3,500 pesos
.
Among the brands compatible with the main software and also, with Alexa and Google Home, are: Demasled, Xiaomi, X28, Sonoff and Hikvision.
There are some hardwired models, which are a bit cheaper, but require reliance on a plug and messy cable.
The wireless ones work with two batteries and being low consumption, they last
at least 5 months
.
If one has a siren connected to a WIFI receiver, a piece that facilitates wireless communication, when the magnets move out of position, it is also possible to activate this horn.
Tips for installation
The set of sensors for doors or windows.
When the opening is closed, the sensor notches should always face each other.
It is not necessary for them to touch, it is advisable to leave them separated by a few millimeters to give rise to the magnetic field.
In order for the magnetic field to be distributed uniformly, the contact between the pieces must be installed on neutral materials.
Like, wood, aluminum or plaster.
On the other hand, if the material is ferromagnetic, such as iron or steel, the magnetic field is attracted by this material instead of acting on the magnet.
Although they include it a lot, it is indicated to use resistant double-sided adhesive tape for the splice.
Since it is easier to place the detectors without having to use screws or plugs.
control application
Smart Life is the best application for home automation.
With more than
50 million users
and some 400,000 compatible products, the Smart Life app, which is completely free, has become one of the most valued home automation systems.
It allows you to link and automate smart devices in a few steps.
It is compatible with virtual assistants, such as Alexa and Google Home.
Network-wide settings can be shared with other family or office members, so they can disable sensors or connect the alarm.
The My Home screen shows all the devices that are active in the home.
From there they can be classified by rooms and know the
status of the sensors
.
For each object (be it a sensor, camera or a smart plug) a series of conditions and actions can be established that, if specified, will fulfill the functions that have been programmed.
For example, if you have a temperature sensor, you can choose what happens when the weather changes.
Or, when the state of a module (opens or closes) what to do next.
Among the available actions it is possible to execute a device, which could be an alarm or turn on a light.
Send notification or choose a scene that includes a battery of measurements.
smart lights
Signify Philips HUE are easy to program and pair with sensors.
Photo Signify.
When the residence is left without occupants, a good way to have a similar presence at all times is to use smart lights such as Philips HUE from Signify.
From the HUE app you can schedule
automatic turn-on
times , save favorite light scenes for each room, and control your home lights from another location.
Among other functions, HUE also allows you to adjust the intensity of the tones, control the on and off remotely and play with the more than
16 million combinations
of its palette.
The Started Kit includes three lamps that are replaced by the existing ones, without modifying any installation, and a bridge that is connected through the WiFi network router.
Its price is
50 thousand pesos
.
In addition, you can add Philips Hue Motion sensors, accessories that automatically turn on smart lights when they detect movement when you walk down the hall or open a door.
The sensors are battery-powered and can be set with the Philips HUE app to turn on at a certain time.
Each sensor is around
15 thousand pesos.
