A simple DIY security alarm. Security alarm systems for summer cottages

Sometimes there is a need to install a simple and inexpensive security alarm. Without unnecessary bells and whistles that manufacturers add to it in order to expand the functionality of their system and somehow distinguish it from other competitors. A cottage, a garage, a household outbuilding or even a greenhouse; in such places it is not always advisable or profitable to install a full-fledged security system.

In this article we will look at several devices that claim to be simple and accessible to anyone who wants to protect their property from intrusion by uninvited guests.

What should such an alarm system be able to do?

• respond to an invasion (some kind of external influence– movement, the door was opened, hit, etc.);
• serve beep to scare off the intruder;
• have the ability to arm and disarm;
• It is advisable to consume little electricity.

The purpose of this device is not so much to block access to the house, but rather to scare away the thief. Having heard a loud signal, he will not want to take risks and will not climb into the room, in addition to psychological impact, it may still attract the attention of neighbors.

Security alarm based on motion sensor

The simplest security alarm for a home can be made with your own hands based on the usual household sensor lighting movements that are installed in entrances to save energy. But instead lighting lamp You can install a siren.

What will you need for this?

• Motion sensor– you can buy it in any hardware store, for example OBI or Leroy Merlin. It is necessary to pay attention to the operating voltage of the sensor - we need it to operate from a 220V network; the viewing angle depends on the external design of the sensor (wall-mounted or ceiling-mounted) and the lens used (can be wide 180 degrees or corridor type). Average cost from 400 to 800 rubles;
• Siren operating from 220V network. For example, PKI-3 “Ivolga-220”, average price 250 rubles. Can be purchased at radio stores;
• Regular switch, to turn off the alarm. Any will do, from 100 rubles. and higher.

The connection diagram is shown below:

You need to choose a motion sensor that has at least two types of adjustments - time adjustment (TIME) and sensor sensitivity (SENS). Using the first one, it will be possible to set the activation time of our alarm, i.e. siren sounding time. This value is usually set for five minutes. The second adjustment changes the sensitivity of the sensor, for example, if it does not respond to you or to reduce so-called “false alarms”.

A switch will be needed to turn off the device when you are in its field of view and turn it on when you leave the room. It is advisable to install the switch covertly, so that after activation burglar alarm you are not within its range of action. In addition to the siren, you can also connect an ordinary light bulb for double impact on the offender.

The main disadvantages of this implementation will be that some models of motion sensors, after being turned on, require from 1 to 10 seconds to “stabilize” and switch to standby mode. If you come across such a sensor, you need to add it to general scheme a time relay that will keep the siren turned off while it is turned on.

There are also miniature motion sensors on sale that operate on 12V, for example, model DD-03. You can also create a simple alarm on them, but you need to connect it to a 12 volt power source or battery. Thanks to this, the system will be non-volatile and work even if there are power outages.

Security alarm from a ready-made kit

The simplest security device based on autonomous alarm system can work wirelessly. In stores for radio amateurs you can find two options - based on infrared sensor(aka movement) or a magnetic contact sensor that reacts to opening. True, the choice is not large enough and you will often have to go shopping to find the product “in stock”. Therefore, the easiest way to purchase this product is to order it in one of the large online stores.

Kit based on an infrared sensor.

An example is the Chinese alarm system under the loud name “Alarm mini”. Consists of the IR sensor itself, a mounting bracket and one or two key fobs. Included: clear instructions for installation and operation. 4 AA batteries are purchased separately, but can also be powered by a 6V power adapter (sold separately). Installing it yourself is not difficult.

After inserting the batteries into the device, you need to install the unit itself in such a place that its lens is directed towards the protected area. The front panel has an infrared receiver window for controlling the alarm from remote controls. A lens that “detects movement” in the controlled area, operation lights and a siren.

We press the button on the remote control - the green LED lights up, which means the exit report has started (15-20 seconds), so that we have time to leave the apartment. Then the green eye goes out - the device has started working. Now, as soon as there is any movement in the room, a person will pass, a dog or cat will run, the red LED will light up and after 15-20 seconds a very loud siren sound will be heard. The device works!

A set based on a magnetic contact sensor.

A security alarm based on an opening sensor is a main unit that contains a sensor with open contacts and a magnet for closing these contacts. You need to set them up against each other so that there is direct contact between them. If a thief breaks into the house, when a door or window is opened, these elements move away from each other and an alarm siren sounds.

Such an alarm can be used mainly to scare off intruders and its main advantage is low price, about 100 rubles per sensor. And very easy installation, on each part there is sticky tape, just remove protective layer and stick the sensor on the front door or window.

Often such kits are used to protect the perimeter of the house while you are inside, for example, sleeping at night. The sound of the siren will wake you up and you can take any action to protect yourself.

Burglar alarm simulator

In urban multi-storey buildings It is becoming popular to put an apartment on guard; in this case, expensive equipment is purchased to protect against intrusion, and the signals are transmitted to the remote control of the security company. But not every owner can afford this, and it’s not always justified.

Remember on cars such a device, under the windshield, usually near the steering wheel, there is a red LED that flashes or is constantly on? He warns that the car is under guard. Likewise, for an apartment or cottage, there are similar designs or, in other words, burglar alarm simulators. They are designed to scare away unprepared and unprofessional thieves or burglars.

To make such a simulator, you need to buy a red LED (for example, this AL307), a mounting box to house it, a 100 Ohm resistor, a switch and a compartment for two batteries. For the entire set you will need to pay approximately 100 - 200 rubles. Depending on the characteristics of the LED, a current-limiting resistor must be connected to it in series. A radio store will help you choose the right resistor (unless, of course, you have a Soviet AL307 LED, as in our example).

When leaving home, we turn it on all the time glowing led When we return, we turn it off. Strangers will think that the apartment is on an alarm system.

Some twenty years ago the only in an accessible way To protect your home, get a guard dog. Since then, technological progress has moved far forward and today it is possible to install a security system that can not only protect the house, but also inform the relevant authorities about an attempt of unauthorized entry. And the effectiveness of such a system lies not even in reliability, but in the fact that its very presence deters attackers.

Important! At the dacha, an alarm system is especially necessary, because a place that is empty most of the year is automatically included in the risk group.

The availability of modern security systems can be explained by their reasonable cost - high quality model costs the same as an average smartphone price category. Most people change their phone every year, but they only think about buying an alarm system after it has been stolen or best case scenario failed robbery attempt.

A service dog in a country house is one of the best guards, but it is better to rely on automation

First you need to decide on the type of alarm. All systems are conventionally divided into several categories and have strengths and weaknesses.

It is indispensable for expensive cottages, banks, storage facilities and large stores - wherever there is a possibility of a targeted and well-planned hacking operation.

Advantages:

• reliability (subject to service by a well-known security company);
• the ability to install a so-called panic button, when pressed, an operational group will arrive;
• The installation will be carried out by qualified specialists with extensive experience in installing various alarm systems.

Flaws:

• duration battery life systems in the absence of electricity does not exceed two hours, after which the security company does not bear any responsibility for the facility;
• high cost security kit(about 90 thousand rubles), as well as a mandatory monthly fee;
• after arriving at the site, the task force must wait several hours and, if the owner is not nearby, and the thieves have locked themselves in the house, then the team will simply leave without taking any action;
• human factor – alarms come to the console they are sitting at ordinary people, often without proper qualifications.

It is also worth noting that the security company bears virtually no responsibility, and everything that is stated in the contract is fictitious in most cases. It is very rare that clients are compensated for damages, but often they are simply ignored, and it is almost impossible to prove anything.

2. Autonomous beepers (sirens)

By “beepers” we mean very primitive security systems, used mainly in facilities where the likelihood of hacking is minimal and there are no valuables. This simple devices, in which the light/sound detector is activated after one of the sensors installed around the perimeter is triggered.

“Sweeters” are useful where the sound of a siren can attract neighbors (in a holiday village, for example) and thereby prevent theft. There are few advantages, or rather, there is only one - low cost. Such alarms cost from 3 thousand (Chinese models) to 30 thousand rubles (relatively high-quality analogues).

3. GSM alarms

These types of security systems, also called “dialers,” are an excellent option for country house. Often, alarms operating using GSM technology not only protect homes from burglary, but are also budget analogue « smart home" So, using SMS messages from your mobile phone you can manage electrical appliances, turn on/off the light, heat generator, turn off the water or gas.

Important! GSM systems work as follows: special hinged contacts when opening front door close and transmit a signal to the phone. The latter, in turn, makes a call to the required number - the owner or the security company.

Advantages:

• affordable price– about 50-60 thousand rubles;
• reliability;
• monitoring the situation in a protected area from another city or even continent;
• compatibility with all existing sensors - contact, infrared, smoke or window break sensors;
• possibility of remote listening;
• elements of a “smart home”, partial control of electrical appliances via text messages from a mobile phone;
• no monthly fee (only system installation is paid for);
• ease of installation and operation.

No particular shortcomings have been noticed with GSM alarms. We can only mention the fact that you need to plan your further actions in the event of an “alarming” call, it is not always possible to respond promptly, and it is not safe to do everything yourself. For this reason, you should first find out the number of the duty station and call it in case of penetration. You can promise the police a reward for catching the intruders - this will increase the likelihood of a positive resolution of the issue.

What to choose?

In most cases, the best option for a dacha is a GSM alarm system. But in this case, you should remember that it (the alarm) requires several seconds to make a call, and if the door closes quickly, the contacts will open and the call will be reset accordingly.

Beeper alarms are not always effective, because the neighbors for whom the siren is primarily intended may simply not be at home.

What to look for

So, we found out that it is better to install a GSM alarm system at the dacha. Now let's look at what you need to consider when choosing a particular model.

1. Is the house heated or not?

If the room is not heated, then it is necessary to choose wired models, since the batteries of wireless systems are not designed to operate at sub-zero temperatures and, as a result, will not last long. But if there is no power supply in the house, then an autonomous security system is the only possible option.

2. Cost

The alarm system must be of high quality, but you should not buy too expensive models. The equipment of such systems can itself become a target for theft.

3. How do the models differ?

Different models may differ in the number and purpose of sensors, battery life. But if the ultimate goal is only fire and security sensors, then you can use any of the existing models.

Defensive lines

The integrated use of different sensors makes it possible to block entry routes into the house. The overlap occurs using several protective lines, which are discussed below.

1. Milestone No. 1 is doors and windows. They are equipped with contact sensors that control closing/opening.
2. Milestone No. 2 – internal motion sensors. The microwaves emitted by them capture the movement of heat throughout the entire area of ​​the protected object.
3. Milestone No. 3 – sensors for temperature, gas, water leakage (in the bathroom, toilet), etc. All of them are connected with a special cable to the main controller. A wireless option is also possible, but such a system will cost several times more.

In case of hacking, the owner receives an SMS notification. Additionally, you can install a siren to scare away intruders.

Important! Don't forget about physical barriers (such as bars), which can put thieves in an awkward situation: the security system has already worked, but the first obstacle has not yet been overcome.

Installation of GSM alarm

Stage one. First you need to determine how to ensure the inaccessibility of the house so that the security system is activated. For example, you can install contact sensors on the front door, and install a second one behind it.

You should also install an external antenna for radio signal transmission. Note that the antenna creates significant interference for the microphone, so both elements must be placed no closer than five meters from each other.

It is better to install the siren in the hallway, away from the device itself. This will disorient thieves and they will not be able to find the panic button.

Stage three. The method of laying the wires is determined. Ideally, they should be hidden in the walls, but this is only possible at the renovation stage. To do this, the walls are grooved approximately 25-35 cm from the ceiling.

Important! The alarm wiring should be laid no closer than 20 cm from the electrical wiring.

But if the repairs have already been made, then there are only two options left:

• special channels for cables;
• wireless sensors.

Stage four. Wires are being laid. For signaling, use the KSPVg brand with a cross section of 0.4x4 mm. You can also use a UTP 0.5x4x2 mm computer cable.

In this case, you need to run a separate cable from each sensor to the device. There are exceptions - temperature sensors and readers that are connected in series.

Stage five. System programming. Usually all the settings are already on the SIM card. First, the card is installed in the device, charging is turned on and the reader is connected. A few minutes after the lights on the reader flash, the power is turned off. The SIM card is removed and installed in the owner’s phone (several entries will already be made in the contact book). You need to change the settings and set a phone number - “alarm” alerts will be sent to it.

You also need to do additional settings(all of them are described in detail in the instructions and depend on specific model), after which the SIM card is inserted into the controller body.

Stage six. All sensors are connected to the device. You don’t need any special skills for this, the main thing is to strictly follow the instructions. Connection can only be made when the power is turned off.

Stage seven. Trial run systems. The device is turned on and applied to the reader electronic key. When the system enters security mode, each sensor is checked.

As a conclusion. Site protection

It is also worth noting that the alarms do not go off if unauthorized persons enter the area. To protect the area, you can equip it with IR motion sensors and then integrate them with the home security system.

There are fewer people outside the city, and getting into private territory is not difficult for an experienced thief. That is why we can say with confidence that the alarm system is country house simply necessary.

How does a burglar alarm system work?

Without going into the technical side of the issue, the principle is quite simple. At least three parts are involved in the security system:

• Detectors
  They react to any action - the breaking of a window, movement in the territory or the opening of a door or gate. After this, a signal is sent to the control panel.
• Control panel
  It monitors the operation of connected detectors. If one of them is triggered and sends a signal, the device processes it and transmits it further - to the actuator
• Actuator
  This is the end point of the security alarm. It causes a specific reaction to the action taken, namely: calls a private security company, private security, turns on a siren or sends an SMS to cell phone owner. Simple alarm with SMS notification - this is great option for your dacha, if you want to secure it well and, if something happens, quickly receive a report of an attempted illegal entry directly to your mobile

Who responds to an alarm signal from a cottage alarm system?
