Probably, it's no secret to anyone that lovers of profiting from other people's good met (and meet) always and everywhere in huge numbers. But modern technologies have stepped so far forward that it will be quite difficult for an attacker, if he knows at least a thousand ways to penetrate private property, to carry out his plan. This is due to the fact that recently complex protective solutions have appeared that combine quite a lot of possibilities. This is a security system for a private house, office, bank, enterprise, etc. Consider the most basic aspects regarding the functioning of such devices.
Security systems for a private house: types and general concepts
So, what is such a system? Here it is worth clearly delineating the complexity of combining the aggregate components of management,tracking options for uninvited guests, types of alerts, as well as options for connecting equipment.
Today, there are three main types of such systems:
- autonomous Smart Home systems;
- wired systems;
- wireless (GSM security systems for a private home or office).
Let's briefly discuss each type. But first, a few words about the equipment used.
Used equipment
If you look, any security system for a private home, office or enterprise, depending on the degree of complexity and the functions assigned to it, should include several mandatory components: a visual surveillance system or the use of motion sensors, an alert system when trying to illegal intrusion (sound or light alarm, instant sending of an SMS message to the owner of a house or office), the ability to block an intruder if he has already entered the premises, a central control panel and an uninterruptible power supply in case of a power outage.
It goes without saying that in the simplest case, for the most part, only motion sensors are installed. Among their types are the following:
- passive infrared sensors that respond to thermal radiation;
- beam infrared sensors with a reaction to the presence of a moving object in the zone of intersection of the rays;
- sensors based onreflections of radio waves sent to a moving object (like the reaction of bats);
- contact magnetic sensors triggered when doors are opened;
- vibration sensors that detect the slightest vibration of the surface on which it is installed (floor, walls, etc.);
- sensors that detect damage to glass in windows or double-glazed windows;
- capacitive sensors for metal, triggered by changes in the parameters of the magnetic field around them;
- combined systems, which include, in addition to the above, the functions of detecting gas or water leaks.
Smart Home Systems
Perhaps today the "Smart Home" systems are the best. With their integrated installation, this includes not only a primitive alarm system for a private house. In this case, several systems are combined into one. That is, the security function is combined with autonomous control of all devices in the house or cottage.
Again, depending on the complexity, such systems can have video cameras, motion sensors, and control devices for gas or water appliances, and use different methods of notification when a particular unpleasant situation occurs. As expected, such systems are completely autonomous, but if desired, their owners can connect them to specialized security services. After receiving an alarm signal, a special team leaves for the scene to deal with the situation, and, if necessary, take appropriatemeasures.
The only drawback is the too high cost of the system itself, and the cost of paying for the services of a security company.
Wired security systems
Wired security system for a private home is the simplest and cheapest. Among the advantages of such systems, judging by the numerous reviews of their owners, one can name the fact that the sensors used do not need to constantly change batteries or charge battery packs.
Naturally, in the event of a power outage, the installation of a special uninterruptible power supply unit should be provided (similar to how it is done for computers). And it goes without saying that any sensors and cameras can be combined into one system. But it all depends on the needs of the owner of the house.
Wireless GSM alarm
Using wires to connect is often legally difficult. What if the house has been renovated? Indeed, for laying cables, for example, in the walls, everything will have to be redone, and these are costs, and considerable ones. That is why many people are actively using wireless security systems for a private home or office.
There are two important features to note here. Firstly, all sensors or IP cameras are connected to the control unit either via Wi-Fi or on a specific radio frequency. Secondly, (why are they called GSM systems) to a pre-registered number or several mobile phone numberssend an SMS message in case of an emergency or even broadcast a video image. But such systems cost an order of magnitude higher than wired ones.
Brief overview of the best manufacturers
As for everything that is currently offered to the market, there are several of the most popular manufacturers, both foreign and domestic:
- Visonic;
- Optex;
- Texecom;
- LifeSOS;
- Jablotron;
- Netatmo;
- Nest;
- Canary;
- Honeywell;
- Piper;
- Samsung;
- Kodak;
- Ademco;
- Guardian;
- Avalanche;
- Granite, etc.
As many of you may have noticed, Samsung and Kodak are on the list. Most of their systems are focused exclusively on video surveillance using a high-definition camera with almost 360 degrees of rotation.
Separately, it is worth mentioning Honeywell products. In fact, this is not a whole system, but only the main unit (Honeywell Tuxedo Touch), with the help of which monitoring and monitoring, alarms, and the functioning of heating, gas and water supply systems are carried out.
Products of other manufacturers are aimed at both private consumers and entire enterprises. Among the products presented, you can find quite a lot of solutions for the types of systems.
Security systems for a private home: reviews
But here's what's interesting. Despite the high qualityproducts, Western manufacturers, for example, are not particularly popular in Russia. Owner reviews show that domestic systems in terms of operation look much more preferable. First and most importantly, they are designed to work in post-Soviet power networks with a voltage of 220 V (and not 230 or 210 as in Europe or America). In addition, such systems do not turn off during significant power surges (we have +/- 10-15%, in the West - +/- 5% of the nominal value).
On the other hand, the systems of Russian developers feel great in conditions of low temperatures or high humidity, although in most cases they are somewhat inferior to foreign counterparts in terms of functionality, as users note.
As it is considered, one of the most interesting is the imported security system for a private house of the Vista model range from Ademco. In part, it repeats the products of the Canadian company DSC, but its main feature is the possibility of almost unlimited addition of new equipment and integration, say, even with lawn irrigation systems or fire alarms.
Among foreign systems, users also note the products of the Israeli company Visonic, which has proven itself well when installed in country cottages or cottage villages.
Professional security systems for businesses
The security system of an enterprise, when compared with the private sector, is quite complex both in terms of the equipment used and in terms of management.
Based on the fact thatthat production areas can be relatively large, hybrid systems from such giants as AXIS COMMUNICATIONS, ASSA ABLOY, BOSCH SECURITY SYSTEMS and others are most in demand.
Their solutions in some cases involve the installation of additional repeaters to amplify the signal of the sensors, which allows increasing the distance between them up to 500 m. In addition, it is possible to use not one, but several control panels (units) or special key fobs that allow raise an alarm manually from anywhere if the main system fails for any reason.
How to make a security system yourself and is it worth it
In general, do-it-yourself security systems for a private house are not so difficult to make. But the essence of the matter boils down to choosing the necessary basic and related equipment and connecting it correctly.
Of course, you can order services from a specialized company, but it's easier to buy everything yourself. It will cost much less. As for the connection, any person who distinguishes plus from minus can connect the devices and the control unit.
Some craftsmen, however, try to solder the circuits on their own, but you still cannot do without professional equipment and fine tuning. So it is better to buy all devices separately. For example, the cost of the simplest system of two sensors will cost an average of 100-120 dollars, the systems are a little more complicated for a private house - already 300-700 dollars, butre-equipment into a Smart Home complex can cost tens and hundreds of thousands of dollars, so think about whether all this is necessary if such a system is not fully involved.
