For those who plan to increase home security, wireless sensors are the first link in DIY (Do It Yourself) home automation. Next, what are the budgets and budgets for building a small home security network based on a Wi-Fi connection.
This intelligent solution allows the collection of information in real time about what is happening inside the house, as well as the simulation of the presence of light to deter potential intruders.
The advantage of these home systems is that you can configure them yourself and program them – they are connected to a Wi-Fi network on the 2.4 Ghz frequency – in particular using free software such as Vita Smart, Tuya Smart or Gosund.
In addition, these wireless sensors are fixed directly on doors, windows or vents. You don’t need to drill holes in walls or have any technical knowledge.
Since it is completely modular, if it requires it, new security segments can be attached. From touch panels, remote controllers, multiple sensors, security cameras, alarms, gates and smart locks.
Progress to the next level of complexity also involves moving to more professional protocols such as Zigbee or Z-wave. This avoids pre-saturation of the network and also increases protection, because it encrypts the communication.
Door and window sensors
Opening magnetic detectors or sensors represent the first security element of a complete alarm system. The parties are elementary and very prudent, which can be notified of any intrusion.
The function of these electronic devices is to supervise the closing and opening of doors and windows or any element that controls the door to different areas of the property.
The detectors are composed of two parts with magnets: one, which is attached to the frame, and the other, which adheres or screws to the moving part.
These poles are in contact with the magnets at all times. So when it opens unexpectedly, the electronic elements detect that this connection has been lost and can trigger an alarm signal.
The price of these feelings, depending on the reason and its scope, is about 3500 pesos. Among the brands compatible with the main program and also with Alexa and Google Home are: Demasled, Xiaomi, X28, Sonoff and Hikvision.
Some models are generally difficult, which are a little cheaper, but the trust needs a plug and a message cable. they work wirelessly on two batteries and have low consumption, they last at least five months.
If someone has a siren connected to a WIFI receiver, the device facilitates wireless communication, when the magnets move out of place, this horn can also move.
Installation tips
When open and closed, the sensor marks must always face each other. It is not necessary to touch them, to leave them separated by a few millimeters seems to cause the magnetic field to arise.
In order for the magnetic field to be uniformly distributed, the contact between the parts must be established in neutral materials. Wood, aluminum, or plaster.
But if the material is ferromagnetic, such as iron or steel, the magnetic field is attracted by this material instead of the magnet.
Although many of them include it, it is recommended to use tape for splice resistance and double adhesive posts. Indeed, it is easier to install detectors without using screws or plugs.
control application
With more than 50 million users and 400,000 compatible products, the Vita Smart app, which is completely free, has become one of the most popular home automation systems.
It allows you to connect devices in a few steps and automate it smarter. It is compatible with virtual assistants, such as Alexa and Google Home.
Network-wide locations can be shared with other members of the family or office, so they can disable sensors or connect to an alarm.
The My Home screen shows all the devices that are active in the home. Then they can be distinguished by rooms and know the state of the sensors.
For each object (whether a sensor, a camera or a smart plug) there can be a series of conditions and actions that, if specified, fulfill the functions of the program.
For example, if you have a temperature sensor, you can choose what happens when the weather changes. Or when the module state (opens or closes) what to do.
Among the actions available, it can execute a device that can be an alarm or turn on the light. Send a notification or select a feature that includes battery measurements.
pain lights
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 the HUE app, you can set a wide range of automatic switches, save your favorite scene light for each room, and control your home’s lights from another location.
Among other functions, HUE also allows you to adjust the intensity of tones, sometimes remotely control and play with more than 16 million combinations of its palette.
I started the kit with three lamps replaced by existing ones, without any modification of the installation, and a bridge that is connected via a WiFi network router. Its price is 50 thousand pesos.
In addition, you can add Philips Hue Motion Sensors, accessories that automatically turn on bright lights when they detect motion when they walk down the hall or open a door.
The sensors are battery powered and can be programmed with the Philips HUE app to turn on at a specific time. Each sensor is about 15 thousand pesos.
