Country houses, as well as other real estate, often become the target of unscrupulous citizens who want to profit at someone else's expense. This article will not talk about expensive houses - multi-storey cottages and mansions. Such real estate is protected, as a rule, with the help of various security structures.
A professionally installed burglar alarm will send a signal to the desk on duty, and the intruders will be detained by the arriving armed squad. Such a security scheme is designed to counter professional thieves and often works in advance - an attacker, a protected object, will bypass it and try to choose a house as a victim, with which there will be less fuss and risk. Everything is good in this scheme, except for one thing - the cost of the service. Payment to the security company will cost a pretty penny.
When you cansave money
If we are talking about the banal theft of garden tools, tools, and even directly the products of dacha agricultural production by persons who try to exchange all the stolen goods for a liquid alcohol-containing product, it is quite possible to do without extra costs. When we are not talking about countering professional burglars (it is unlikely that they will covet a screwdriver with a "grinder" or a jar of homemade pickles), then the alarm system for giving with a "howler" will quite cope with the task. For a contingent of country thieves is quite enough to simply scare away.
Moreover, once caught in this particular area, becoming for some time the object of attention of the owner of the cottage and neighbors, the subject is unlikely to be drawn there again. After the burglar alarm makes him famous, showing up in the area will be out of the question.
Scope of application
Some dacha cooperatives are completely deserted in winter, even the road to them is not cleared of snow. In such areas, the signaling for giving with a "howler" in the winter becomes useless. It serves as an excellent, inexpensive, but effective remedy for garden thieves in the summer season.
If the owner is in the country, but for one reason or another cannot visually control the entrance gate, the entrance to the house, the alarm for giving with a "howler" will give a signal that there is an outsider in the area and frighten off a potential intruder.
Leaving forcity, it is necessary to warn the country watchman that the "hacienda" is on an audible alarm. It is also great to have good relations with neighbors who can insure "if anything happens." To do this, you do not even need to enter into a physical confrontation with persons who have entered someone else's site. It is quite enough to remember the signs of crooks and call law enforcement representatives.
What is
The alarm for giving with a "howler" is a combination of the "howler" itself, the control unit, sometimes the power supply and various sensors. The kit also includes a device for arming and disarming the object. Siren "howler" acts as a deterrent to intruders. A working sound device creates discomfort, puts enormous psychological pressure on the thief, attracts people to the scene and, ultimately, forces him to leave the facility.
Sensors - a link that directly reacts to penetration into housing. There are different types, each of which is designed for its own "line of defense":
- The vibration sensor is usually attached to a vertical surface, reacts to any change in the position of bodies in space, is used to prevent penetration into the home through gaps in the walls, and is also glued to the glass of windows.
- The glass break sensor is glued to the glass, it reacts to the sound of a certain tone (with which the glass breaks).
Reed switches (for breaking) are installedsets of two elements - one element on the door leaf, the second - on the door frame, the operation occurs when the elements move away from each other
Motion sensor (second name - infrared). Any change in objects, bodies in the room, due to the laws of refraction of rays, causes a change in the infrared background. This effect underlies the operation of the sensor, it reacts to any movement on the object and, in fact, is able to replace all other types of sensors
The power supply unit provides the sensors and the howler with electric current of the required voltage, the control unit coordinates the operation of the entire system. Often the "howler", the control unit and the power supply are assembled into one housing. However, the possible repair of the alarm in this case becomes more complicated.
Wired or wireless
Communication between the sensors and the control unit can be provided both with the help of electrical wires and wirelessly (these technologies are so common today that you will not surprise anyone with them). Both methods have both advantages and disadvantages. The advantages of wireless communication include the absence of the need to lay a cable to each sensor. In the rest - continuous shortcomings. Any wireless sensor must be supplied with a battery. A dead battery can cause a false alarm of the system, and this is unpleasant. In addition, if the alarm works in winter, the battery life at low temperatures will be several times less. So it's betterif the siren-"howler" in the country will be equipped with wired sensors.
Mounting Features
The control unit of the security system is better to be located discreetly, but at the same time not far from the entrance to the housing. This is necessary in order to be able to quickly turn off the signal in case of accidental operation, until all the neighbors have come running. In this case, it will also be easier to repair the alarm. When choosing a location for the control unit, you should also take care of the possibility of supplying power.
It is also important where the "howler" itself is located. The 220V alarm, of course, is mounted partly based on the location of the electrical wiring, but the sound source itself must be installed in such a way as to not only frighten off intruders, but also signal neighbors.
Where is the best place to place sensors
Never trust one type of sensor, and never trust one sensor. Even a good expensive motion sensor alone is unlikely to cope with the task.
Motion sensor is the champion of false positives. The fact is that even sunlight, which has changed dramatically from a sudden cloud, causes a change in the infrared background in the room. And although modern electronics can filter such signals by adjusting the day and night sensitivity, failures still happen. Therefore, it is better if there are two of them in each room. Some systems are configured in such a way that an alarm is generated only when a certain number of sensors are triggered.
Windowsare protected by both break sensors and vibration sensors. However, you need to be careful with vibration sensors, especially with single (which is not uncommon in country houses) glazing. Activation can be triggered by strong gusts of wind.
If the walls of the house are made of a material that is easily opened, it is necessary to additionally protect them with vibration sensors. Finally, reed sensors should ideally be present on everything that opens - all doors, windows, the entrance to the attic (second floor).
A useful option is the availability of GSM
When a howler alarm is chosen for a summer residence, the price, of course, matters. But there is one option for which it is worth paying a little extra. This is a GSM communication capability.
It works like this. The user buys a SIM card of any mobile operator (it is important that the connection with this operator is stable at the place where the alarm is installed). "Simka" is installed in a special slot available in the control unit. Such a system, simultaneously with the sound signal to the "howler", sends SMS to the numbers entered into the control unit in advance.
Moreover, SMS are sent not only in case of unauthorized entry into the house. Devices equipped with backup power sources report the interruption and the beginning of the supply of electricity to the network. The owner is also informed about the failure of one of the sensors.
Reviews of summer residents
Is this signaling effective? Reviews, of course, are heterogeneous. The largest number of complaints comes to cheap Chinese systems. The sensors are triggered by themselves, the control unit “loses” them periodically, etc. However, all of the above applies equally to any electronic devices.
Along with the complaints, there are also a number of positive reviews with examples of howler alarms turned out to be on top. The secret of the success and popularity of these devices lies in the fact that, despite the simplicity of their design, they act in a complex way:
- create a zone of maximum discomfort in the room;
- psychologically "pressure" on the attacker;
- give a signal about the penetration of housing to neighbors and watchmen;
- easy to install, including without the involvement of specialists;
- have a low cost.
The right side of the issue
Some makeshift security devices are tough on intruders. And the law on the protection of private property, oddly enough, does not protect the owner of the house from liability for harming the he alth of intruders.
When operating the "howler" alarm, the permissible sound threshold of the device must not be exceeded. A sound with an amplitude of more than 185 decibels is considered deadly in terms of loudness.
