Probably, it’s not a secret to anyone that lovers to profit from someone else’s good have met (and are) always and everywhere in huge quantities. But modern technology has stepped so far forward that an attacker, if he knows at least a thousand ways to infiltrate private property, will be quite difficult to implement his plan. This is due to the fact that recently there have been comprehensive protective solutions that combine quite a lot of opportunities. This is the security system for a private home, 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 necessary to clearly distinguish between the complexity of combining aggregate management components, tracking capabilities for uninvited guests, types of alerts, and equipment connection options.
To date, there are three main types of such systems:
- Autonomous systems "Smart Home";
- wired systems;
- Wireless (GSM security systems for a private home or office).
Briefly dwell on each type. But first, a few words about the equipment used.
Equipment used
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 an attempt is made to illegally invade (sound or light alarm, instant SMS sending to the owner of the house or office), the ability to block an attacker if he has already penetrated the premises, the central control panel and unit b 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, the following are distinguished:
- 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 rays;
- sensors operating on the basis of the reflection of radio waves sent to a moving object (according to the type of reaction of bats);
- contact magnetic sensors that are triggered when the doors are opened;
- vibration sensors that detect the slightest vibration of the surface on which it is installed (floor, walls, etc.);
- sensors that detect glass damage in windows or glass;
- capacitive sensors for metal, triggered by a change in the parameters of the magnetic field around them;
- combined systems, which include, in addition to the above, the functions of determining the leakage of gas or water.
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 the autonomous control of all devices in the house or cottage.
Again, depending on the complexity, such systems can have video cameras, motion sensors, and gas or water devices monitoring tools, and they use different warning methods in case of an unpleasant situation. As expected, such systems are completely autonomous, but if desired, their owners can connect them to specialized security services. After receiving the alarm signal, a special team leaves for the scene to deal with the situation and, if necessary, take appropriate measures.
The only drawback is the very high cost of the system itself and the cost of paying for the services of a security company.
Wired Security Systems
A wired security system for a private house is the simplest and cheapest. Among the advantages of such systems, judging by the numerous reviews of their owners, we 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 , a special uninterruptible power supply unit should be provided (similar to how it is done for computers). And it goes without saying that you can combine any sensors and cameras into one system. But here it all depends on the needs of the owner of the house.
Wireless GSM Alarm
Using wires to connect often causes legal difficulties. But what if the house is renovated? After all, for laying cables, for example, in the walls, you will have to redo everything again, and this is a cost, and considerable. That is why many actively use wireless security systems for a private home or office.
Two important features are worth noting here. Firstly, all sensors or IP cameras are connected to the control unit either via Wi-Fi or at a specific radio frequency. Secondly, (why they are called GSM systems), an SMS message is sent to a pre-registered number or several mobile phone numbers in case of an emergency or even to broadcast a video image. But such systems are much higher than wired ones.
A brief overview of the best manufacturers
As for all that is currently offered on the market, we can distinguish several of the most popular manufacturers, both foreign and domestic:
- Visonic;
- Optex;
- Texecom;
- LifeSOS;
- Jablotron;
- Netatmo
- Nest;
- Canary;
- Honeywell
- Piper;
- Samsung
- Kodak;
- Ademco;
- "Sentinel";
- "Avalanche";
- Granite, etc.
As many have probably noticed, Samsung and Kodak are on the list. Their systems are mostly focused exclusively on video surveillance using a high-resolution camera with a rotation angle of almost 360 degrees.
Separately, it should be said about Honeywell products. In fact, this is not the whole system, but only the main unit (Honeywell Tuxedo Touch), with the help of which it monitors and monitors, and alarms, and the functioning of heating, gas and water supply systems.
The products of other manufacturers are oriented both to the private consumer and to entire enterprises. Among the presented products you can find quite a lot of decisions on the types of systems.
Security systems for a private house: reviews
But that’s interesting. Despite the high quality of products, Western manufacturers, for example, are not particularly popular in Russia. Owner reviews show that domestic systems look much more preferable in terms of operation. First and foremost, they are designed to work in post-Soviet power grids 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).
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 analogues in terms of functionality, as users note.
It is believed that one of the most interesting is the imported security system for a private house of the Vista range from Ademco. In part, it repeats the products of the Canadian company DSC, but its main feature is the possibility of almost unlimited adding new equipment and combining, 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 in work when installed in suburban summer houses or cottage villages.
Professional security systems for enterprises
The enterprise security system , when compared with the private sector, is quite complex both in terms of equipment used and in terms of management.
Based on the fact that production areas can be residually 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 require the installation of additional transponders to amplify the sensor signal, which allows to increase the distance between them up to 500 m. In addition, it is possible to use not one, but several control panels (blocks) or special key fobs that allow you to send an alarm manually from anywhere if the main system for some reason did not work.
How to make a security system yourself and is it worth it to do
In general, it is not so difficult to make security systems for a private house with your own hands. That's just the essence of the matter comes down to choosing the necessary main 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 can distinguish between the devices and the control unit, distinguishing plus from minus.
Some craftsmen, however, are trying to solder the circuits on their own, but you still can’t do without professional equipment and fine-tuning. So it’s better to buy all the appliances separately. For example, the cost of the simplest system of two sensors will cost on average $ 100-120, the systems are a little more complicated for a private house - already $ 300-700, but re-equipment in the Smart Home complex can cost tens or hundreds of thousands of dollars, so what do you think if all this is necessary if such a system is not fully involved.
