The protection of personal property is a matter that is relevant at any time of the year. Since time immemorial, and under any economic system, there are people in society who are trying to live off theft and theft. To protect your property, you have to resort to costly tricks, hire security or install an alarm system. It's great if financial opportunities allow it. And if not - to help people's savvy and the ability to keep simple tools in their hands. Models for dachas, garages and other premises are not so difficult to make.

What is a dummy alarm used for?

An imitation of a security alarm system is a device that by its appearance does not differ from a real alarm. It consists of a housing, LED and battery.

CCTV cameras are used in security technology to protect objects from unauthorized entry and keep a record of events in the protected area. Along with the sensors that react to the opening of doors and windows, capacitive motion and tracking sensors, the cameras produce visual control. Modern instruments are able to fix motion not only during daylight, but also at night, using shots in the infrared spectrum of radiation. Every year the technique is improved, the dimensions of the cameras are reduced, and the resolving power is increased.

But all these achievements in the sphere of high technologies for the average citizen are inaccessible. The cost of such adaptations is too great for them to be applied on the scale of country cottages or in a garage cooperative, where petty thieves pick up anything that "wrong" lies or penetrates into the house, "accidentally" breaking a window and declaring later that it is so It was.

As in any war, the winner is the one who will be able to outwit the enemy.

And here the illusion comes to the rescue. A thief can not know for sure what surprises await him inside the house. Before trying to break a lock or a window, he often looks around - in fact the punishment for theft and hacking has not been canceled yet. Noticing that there is a camera hanging on the house, the indicator of which flashes brightly, he will once again think about whether to go to search for more accessible.

Of course, on the other hand, the presence of a camera can lead to the idea that there really is something valuable in the house (even if the camera is not stingy). But in order to test this idea, you need to do additional work - to collect information, analyze the "state" of the owners, etc. In any case, the attempt on the "object" to be postponed to indefinite time.

To deepen the originated doubts, except for the fake camera, you can create additional confirmation of the seriousness of the protection - the nameplates that warn "Passerby that the object is under protection, the symbols of howler in the background, etc. It is very effective mysterious and alarming flicker, making its way through the curtains under cover the night.

The creation of such effects is a creative activity and in the end, entourage can play its decisive role, catching on the "gentleman of luck" mystical horror.

Technical maintenance, with modern high-capacity batteries, is not difficult. The model of the security camera costs quite democratic money, because this is just an accurate imitation of the case, equipped with a single device - a red LED, powered by a finger battery.

The same pulsating LED can be placed inside the house, for the assembly it will need old Chinese walkers, a red LED or purple (preferably one that consumes less electrical energy, and, therefore, will work longer) and soldering iron. A detailed assembly algorithm is described below.

Pros and cons of the alarm simulator in the country and for other purposes

Pros of the dummy equipment are obvious

• Financial accessibility. The acquisition of such equipment will require no more than 5-10 dollars.
• Guaranteed result. If we consider the risks of invasion in the absence of any signs of signaling, then they are much higher than the possibility of an attempt on housing with attached, even fake, cameras.
• It can serve as a good addition to a real security system located inside the house, for example, by means of an alarm system with the help of a cell phone or the inclusion of a "howler".
• Ease of installation. To mount and strengthen the camera on the house independently on forces to any adult man.

The disadvantages of simulation equipment.

Of course, the main minus is also understandable. It consists in the fact that this construction can not seriously impede theft. If you get into the house, a really serious criminal will gather, he will do it sooner or later.

How to make a dummy with a blinking LED with your own hands

If you do not wish to sacrifice a simple electric alarm clock and several hours of time, you can assemble a device that looks very much like a real alarm.

To do this, you need to disassemble the clock. Remove the protective cover and get to the electronic board creating and sending current pulses to the stepping mechanism. It looks so.

The figures in the figure indicate:

• , - outputs to the stepper mechanism
• 3 - alarm activation contact (alarm)
• 4 - negative terminal
• 5 - positive terminal
• 6 and 7 - alarm clock terminals

Of course, the alarm turns off as unnecessary, and all attention is concentrated on terminals 1, 4 and 5. Using a heated soldering iron you need to assemble such a circuit.

In fact, the task is to connect the LED and another battery identical to the one that feeds the clock to the current circuit. You can use a cassette from an old flashlight designed for several power supplies, or you can connect two batteries to one, soldering to them metal jumpers.

Since the circuit will be used in non-stop mode, it does not need a power switch.

As soon as the batteries are connected, the LED will start to light and go off at a frequency of, Hz, that is 2 times per second.

Now all this "device" needs to be properly placed in the house before leaving. Mice to him, of course, are not terrible but better, if the capacity is relatively tight. This will significantly extend the life of the batteries. One option is a glass liter jar closed with a nylon lid. Among other things, the glass will create additional light amplification of the "signal".

Based on the logic of setting the alarm, it is necessary to place the jar somewhere at the chest level, but so that the light pulsation can be clearly seen through the curtains of the windows.

If there is a case from the old security camera, the mechanism can be mounted in it, removing the LED to its original location. Have the camera, most often, on the ceiling inside the house (on the front door line) or on the wall outside.

I had to attend one state structure (budget sphere) at their work in the corridor, there were many flowers in pots and even in tubs still Soviet, on the walls there were 6 stands with ads. So they had a very big problem - they are disgruntled visitors and just vandals. Stands constantly had to be repaired and updated, some of them looked just horrible and the authorities for these matters did not even just put a man on and that would not keep track. I advised you to buy a stunt. We did not buy it right away, but then we hung it in a corner and wrote an advertisement stating that video surveillance is being conducted and since the state institution is records with the application will be sent to the appropriate authorities... And the funny thing is that everything almost immediately became normal with the order in institution)))

I am engaged in business in the distribution of advertising in shopping malls, business centers and hypermarkets. So, in the hypermarkets constantly racked up the rack with leaflets (honestly, for me it remains a mystery what motivates people when they do it, but the fact remains a fact). The stands are not ours, but the client, but after the 4th broken rack (and they cost him 10 typs each), he thought about stopping placing himself in hypermarkets (customer loss = loss for us). It was necessary to quickly come up with a quick, inexpensive, but effective way to eliminate vandalism. Stickers that the video surveillance is being maintained did not help. Therefore, we bought here such a dummy, which a non-professional will never distinguish from the original. It's been hanging for months now, the stands are standing.

How long will the model

The lifetime of the simulator depends on the power supply. Finger battery type AA, in the mode of permanent power LED can last from 6 to 9 months. There are frost-resistant types of such batteries, the price of which is slightly higher, but the chances that the battery will "leak" at the first serious frost are much less. In addition, different LEDs consume a different amount of electricity. This must be taken into account when purchasing them in the store. Most of all, the current consumes a white LED. The least is purple.

Despite all the optimism when installing an imitation dummy, you should still remember that "God takes care of the bereaved". Leaving the cottage in the autumn, you should not leave valuable items there. It's better to be safe and take them away with you until next season. If this is not possible, then try to hide everything you need in hard-to-reach places, such as an attic or a securely locked cellar.
