The issue of protecting their territory and personal property is always of interest to every owner. Often, owners of a suburban area get a watchdog, but if a person is rarely at home, the problem of feeding the animal arises. In this case, an electronic device comes to the rescue. Nowadays, the GSM alarm system Sentry or its other variant – Smart Sentinel – is very popular for dachas. Although, besides this, there are other similar types of security systems, they all work on the same principle.
How does GSM alarm work?
The modern market offers many security devices. In addition to the Smart Sentinel, the GSM Dacha 01 system has proven itself well. It can also be found under the name TAVR. However, no matter what the brand is named, the main element of any GSM system is the sensor. When an attacker tries to enter someone else's territory, he falls within the range of an electronic device. The triggered sensor instantly sends a signal to the phone of the owner of the dacha.
Modern security systems with a GSM module can be equipped with several sensors that play different roles, for example, a microphone or a video camera.This allows the owner of the dacha to hear and see the full picture of what is happening on his territory. Thanks to the microphone, the owner has the opportunity to listen in at any time by calling the dacha by phone.
Main types of GSM security systems
Regardless of the brand of security system, all GSM alarms differ in the installation method:
- The wired model involves connecting sensors to the main unit using wires. This is often very inconvenient, plus a low level of security. If the wire is damaged, the sensor will not be able to send a signal. That is, the object remains unprotected.
- The wireless model uses a radio channel. The signal from the sensor at a certain frequency is supplied to the main unit, which in turn sends it to the programmed phone number.
Both types of alarms can operate when connected to the mains or autonomously. The second option is most acceptable for a summer residence. Even after a power outage, the facility will remain protected. The autonomous system is battery powered. You just need to recharge it periodically.
A wired and wireless system equipped with a GSM module is capable of working with many sensors. For example, an alarm can notify the owner of the appearance of smoke, flooding of the room with water, gas leaks, etc. A temperature sensor is very convenient to use, allowing you to control the operation of the heating boiler and maintain the desired temperature in the room. The electronic device can even be installed on the door, and the owner will know when it was opened.
What parameters are used to choose a GSM security system?
Before choosing a GSM security system, you need to decide under what conditions it will work. Dachas are not always heated in winter, and electronics must withstand temperature changes. To do this, it is optimal to purchase a model that can work in heat and cold. The next important issue is non-volatile operation. The battery capacity should be enough until the next recharge upon the owner’s arrival if the electricity supply to the house is not restored. And, most importantly, you need to decide which sensors are needed.
Budget alarm system for a summer residence has the following functions:
- the owner can remotely learn about the operation of the system;
- arm and disarm an object over the telephone;
- programming more than one number to which the GSM module will send an alert;
- the owner has the opportunity to independently record any text of the notification and, if necessary, correct it;
- wiretapping of a protected object.
More expensive security systems are equipped with additional functions;
- changing the language of the settings menu;
- no voltage indicator;
- sending a message about signal loss;
- using different passwords;
- communication through a microphone between people located in different rooms of the building.
Very advanced, expensive systems are equipped with sensors that respond to window glass breaking, gas or water leaks, smoke, etc. in the house.
GSM alarm equipment
Wireless security systems from different manufacturers differ in sensor configurations and battery capacity for autonomous operation. Standard autonomous GSM alarm system consists of the following elements:
- main unit – GSM module;
- mains power supply;
- battery;
- two control key fobs;
- door opening and motion sensor;
- USB cable for connecting to a PC to make settings.
Depending on the model, alarms may be equipped with additional sensors and buttons for generating an alarm.
GSM module
The block is the heart of the system. The module receives signals from all installed sensors. After processing the information, the electronic device sends a message to the specified phone numbers. To activate the system, a SIM card is installed in the module. An important condition is that there is no PIN code request. In addition, the card should contain only those numbers where the signal will be sent. All others need to be deleted.
Sensor kit
From the very beginning, you need to decide what sensors are needed to reliably protect your dacha. Undoubtedly, the first place is given to electronic devices that respond to movement. You will need many such sensors. They are installed around the perimeter of the site, near windows, entrance doors and inside the house. Motion sensors work on the principle of infrared radiation, so they can be easily damaged if covered with something. To ensure inaccessibility to the device, installation is carried out at a height of about 2.5 m.
It wouldn't hurt to put a reed switch on the front door. These door opening sensors come in several varieties. Reed switches are produced with sensitivity for large steel gates and standard ones for PVC or wooden doors.
If your dacha is left unattended in winter, it would be a good idea to install a glass break detector on each window.All other electronic devices that react to gas, smoke, water are optional. Such sensors are more needed for your own safety.
Sound sirens
A sound siren is needed to scare away intruders from the dacha. When a danger signal is received from the sensors by the GSM module, it in turn sends a pulse to an electronic device that produces a loud sound of about 110 dB. A sound siren will notify neighbors in the country about the possibility of a break-in. They will immediately call the police or inspect your area themselves.
Wireless key fobs
Typically, any GSM alarm system is equipped with two key fobs. They are needed to turn the system on and off. The key fob may have an alarm button, which, when pressed, triggers the siren. An electronic device operates at a short distance from the house. If, upon approaching your yard, suspicious people are noticed on the territory, the alarm button turns on the siren to scare them away.
CCTV sensor
This electronic device is equipped with a video camera. She films everything that comes within her field of action. When danger arises, recording is automatically started. The GSM module begins to send captured frames to the specified telephone numbers. The unit can even be programmed so that the captured information is sent to the e-mail specified by the owner of the dacha.

Conclusion
The convenience of wireless alarms is due to the unlimited number of sensors.In addition to security functions, the electronic device can turn on the watering of the site or home heating in the absence of the owners of the dacha.
