How to make a security alarm system for the house with your own hands

For all homeowners, keeping their house safe and secure is of utmost importance. An effective alarm system is one of the most important parts of home security. Even though the market is flooded with options for commercial security alarm systems, building your own DIY system can be rewarding and affordable. This guide will show you how to make a personalized security alarm system for your house out of readily available materials and basic installation methods.

It’s crucial to comprehend the basic ideas underlying the operation of security alarm systems before getting into the finer points of creating your own. A security alarm system’s main purpose is to identify any unwanted entry or intrusion into your house and notify you or the authorities that there may be a threat. A variety of sensors and detectors positioned thoughtfully throughout your property can help achieve this.

Motion detection is a crucial part of any home security alarm system. Motion sensors are gadgets that, when they detect movement within a predetermined area, sound an alert or send out a notification. These sensors can be as simple as mechanical switches or as complex as infrared (PIR) or ultrasonic sensors. You can effectively keep an eye out for any suspicious activity in your home by strategically placing motion sensors throughout.

For your home’s entry points to be secure, door and window sensors are just as important as motion sensors. Usually, these sensors are made up of a switch and a magnet. The magnet and switch are near each other when the door or window is closed, signifying that the entry point is safe. On the other hand, the magnet moves away from the switch when the window or door is opened, setting off the alarm. An additional line of defense against possible intruders is provided by installing these sensors on all doors and windows.

The next step is to decide how you want to monitor and control your DIY security alarm system after you have assembled all of the required parts. One choice is to link the alarm system to a hub or central control panel, which can then be accessed remotely using a computer interface or smartphone app. As an alternative, you can choose for a stand-alone alarm system that, in the event of a trigger, will sound a loud siren to warn you and your neighbors of the possible threat. Regardless of the approach you take, make sure you test your alarm system frequently to make sure it is operating correctly.

Features of GSM alarm system using a cell phone

A GSM alarm system uses a mobile communication channel to send out a message about potential intruders entering the home. Additionally, the owner of the property as well as a security company employee with whom a special contract has been signed can both receive this alarm signal.

An alarm system calls the property owner to report

Similar to other security alarms, this one uses a system to notify the phone in the event of a burglary. The central unit and the sensors that make up its main components are regarded as a type of "senses." As a result, every system component responds to a different stimulus. The device placed close to the house’s entrance detects movement, and the one attached near the door is activated when it is opened. These devices’ job is to detect any "event" and "tell" the control system about it over a radio channel, enabling you to return home in a matter of minutes.

After receiving a signal from the sensor, the central unit—which serves as the alarm system’s brain—acts as planned:

  • makes a call to the property owner;
  • sends an alphabetic message to his phone;
  • makes the siren sound.

GSM is the only network via which information is transmitted.

If a microcontroller is installed, the alarm system’s phone can be controlled remotely.

Using a security system linked to a cell phone and other devices

When owners of homes or garages need to be notified of events like these, the system is installed.

  • intrusion into a dwelling, garden, garage by unauthorized persons;
  • power failure;
  • smoke in the room
  • gas leakage from the gas pipe in the apartment;
  • Water leakage;
  • room temperature drop;
  • the need to disconnect from the power grid household appliance, such as a heater.

We’ll walk you through building your own DIY home security alarm system in this article. You can improve home security without paying for costly expert services by implementing these measures. We’ll go over the essential parts you’ll require, such as motion sensors and sirens, and offer detailed setup instructions. You can feel more at ease knowing that your house is better secured against intruders with a little time and effort. This guide will give you the confidence to take charge of your home security, whether you’re a do-it-yourself enthusiast or just trying to save some cash.

Components of wired alarm system with GSM module

If you choose to put together this kind of security system on your own, get ready:

  • old button phone (for example, Nokia 3310) – the basis of the alarm system;
  • a sealed switch (reed switch);
  • a conventional battery charger (or a capacitive battery for the phone);
  • a long length of wire;

The phone’s button is reached by the tampering information along the chain.

It should be a standard push-button phone.

Installation of security system elements in a private house or dacha

The phone button, reed switch (which opens in a magnetic field), and switch—all of the GSM signaling components—need to be connected in series. The procedure suggests completing a few tasks:

    On the phone set up the function "quick call", using any button for this purpose. It will call the number of the property owner at the moment of alarm system response to any incident.

You can choose to customize with the number "2."

The creation of an alarm system will require keyboard work.

Wires must be connected to the open buttons.

The alarm system’s connection is contingent upon the functioning of the phone.

It is acceptable to power the device with a battery.

Testing of the assembled device is required. It should operate as follows: when the door opens, the reed switch senses it and closes the phone button’s contact, quickly setting up a speed dial for the property owner. The object’s owner will learn what transpired in the safe haven after accepting the call.

Such an alarm system can be made to talk if desired. The primary requirement is that the phone’s microphone must be in good operating order.

Installing an alarm system with a time relay with your own hands

The alarm system installation is done a little bit differently if the security system needs to incorporate a relay that offers a specific order of operation of the scheme’s elements:

  1. The panel is removed from a simple cell phone.
  2. Two wires are connected to the contacts of a single button for a quick call to some caller.

One of the parts that sends a signal to the phone is the time relay.

Relays require a slightly different connection scheme than standard ones.

You can buy a relay at the store.

The phone key is closed by a relay.

Disadvantages of homemade home alarm system in the apartment

Homemade security alarm systems have several benefits, including the ability to be updated, low cost, and the ability to be assembled using unconventional materials. However, there are also some serious drawbacks to using them.

The primary drawbacks of their homemade GSM alarm system are taken into consideration:

  • lack of a built-in security device, thanks to which intruders will not be able to disable the alarm system;
  • prohibition of communication with a private security company;
  • difficulties in assembly, especially if the system includes many sensors and actuators;
  • The inability to record audio or video from the scene, even if the system will be connected to a PC;
  • the need to be well versed in electronics.

Keep in mind that fixing the homemade alarm system won’t always be feasible.

Reviews about the effectiveness of a homemade security system with motion sensors

Engaged in gsm-alarms, but put not on cars, but on premises, ATMs, etc. д. The essence, I think, does not change, similarly installed sensors, for example, on the doors, windows, connected to the device with a SIM card, which sends signals. It works, sends signals quickly, but much depends on the operator and the place of installation of the device, so that the signal does not interfere with anything and not blocked. Convenient, feedback is available, inexpensive. The only disadvantage is the dependence on the operator, who may have failures and the signal may be delayed. For example, on New Year"s Eve, when the network is overloaded.

Dob84 is the link.

GSM alarms are the way to go. It"s wireless, meaning no one can cut the air. The trick is that it works the way you want to customize it. You can turn it on and off for certain areas, for example, for movement, when doors and windows suddenly open without your knowledge, or if someone breaks them. It reacts to fire, or rather, to the presence of smoke, to gas, too. All the information is programmed into the central unit. You can turn everything on there. You leave the house, put it on the signal, you can control it from your cell phone. You can turn it on or off via access code.



GSM alarms aren’t all that great, in my opinion. Depending on which side you evaluate, this alarm system is a tidbit for the pros. Additionally, there are more drawbacks than benefits on this side. An inexhaustible quantity of signal jammers, shoddy installation, poor communication, and multiple failures. I’m not sure; there are other approaches that are far more fascinating than the widely used alarm systems. Kirichenko, Alexander The system of bezopasnosti dlya doma f111 can be found at
