In burglary protection, alarm systems are the most efficient. At an attempt of intruder to gain entry into a protected area, motion detectors or door/window magnetic contacts will alarm the central office. The central office will activate the siren and, at the same time, dial preprogrammed cell phone numbers and notice the owner that the attempted burglary is in progress. As a domain, video surveillance is experiencing true expansion nowadays, thanking to a numerous possibilities of direct monitoring, recording and examination of recorded situations. Video surveillance equipment made by world renowned manufacturers provides security, better control, as well as prevention of forbidden activities.

Combining video surveillance and alarm system will give you the highest security.

Voice over Internet Protocol i.e. VoIP represents voice communications and multimedia sessions (video conference etc.) transfer technology through IP networks such as Internet. Instead of classical phone lines, contemporary paths of broadband Internet are used for voice transfer. In accordance with our business policy, our solutions are primarily intended for business beneficiaries. Reasons why you should decide on application of this solution are indeed numerous, and we are using the opportunity to bring up some of them:

IP telephony eliminates technical limitations of number of extensions within your company. Unlike most of classic telephone central offices, now there are no technical constraints in terms of number of extensions that can be connected to the system.
It uses the existing network infrastructure and enables data, video and voice communication integrated into a single, easy to handle, service.
IP telephony allows application of advanced functions that can’t be used with traditional telephone central offices or are subject of additional charge. Some of these include: caller number display, call waiting, call forwarding, automatic call forwarding, conference calls, voicemail-to-email forwarding, fax-to-email forwarding, sending fax by email, video calls, assigning and denying access rights towards outer phone numbers and destinations (abroad for example)…
Connecting with other headquarters (subsidiaries, branches, business partners) and free communication.
Connecting to the central office from a remote location – you are not related to your workplace and your phone can be used at any location that is connected to the Internet.
Simultaneous connection with different telephone service providers (PSTN, GSM, VoIP) and redirection of calls through most favorable route.
Displaying all calls – dialed number, call setup time, call termination time and call duration time.
Total savings can amount to 40% or even 70%, depending on the structure of your phone calls. The biggest savings are realized when calling abroad.

In case of electrical energy supply termination from power distribution, the most important supply is provided from auxiliary sources of electrical energy. An example of consumers that must not be left without power are: lighting and equipment of operating rooms, phone centrals, elevators etc. Types of auxiliary sources used today include generators and electronic devices (UPS).

UPS is an abbreviation for Uninterruptible Power Supply. UPS is used for uninterrupted supplying of low-power devices like computers, telecommunication equipment, faxes etc. Generators are used for supplying greater consumers. Types of generators include manually and automatically initiated by the electrical energy supply termination from power distribution. Automatically initiated generators have built-in electrical heaters for the engine, ensuring working temperature and thus full engine load.

Switching of the consumers from power distribution supply to generator can be made manually by drum switch or automatically by contactor. When deciding on generator power, care should be taken on overall power of the consumers as well as their characteristics. For example, electric motors with direct matching use five times stronger power during start off than during its normal operation. Therefore, for starting up an engine of 2.5 kW power, generator of 10kW and higher power is needed. In facilities of greater importance, UPS and generators are installed, where more important systems are supplied via UPS, and others via generator.

Optical cables enable exceptionally fast data transfer between geographically remote locations. Nowadays, the Internet is unimaginable without the use of this technology. Considering the fact that the continents are connected by optical fibers, it is possible to access content from across the globe in a matter of milliseconds.

Advantages of optical cables in comparison with copper cables are:

  • smaller dimensions,
  • possibility of transferring large amounts of information,
  • low signal loss allowing range of up to 200 kilometers with no need for signal amplification,
  • less weight per meter,
  • lower linear density (cable weight per unit length),
  • lower costs,
  • insensitivity to electrical interference, water, high and low temperatures.

On the other hand, ionizing radiation does affect optical fiber cables. Currently, technology of connection via optical cables represents the most modern way of connecting to the Internet and enables using the most advanced services available today.

Within equipment installation, we offer you laying of the optical cables regardless of the way of their installation, as well as services of electrical splicing, measuring of chromatic dispersion, polarization mode dispersion and attenuation profiles. We provide services of regular and preventive maintenance of optical backbone and user-access network, for all of our users and partners.

Electrical installation of Ticino system

One of the most common ways to perform electrical installations.
Sistem postavljanja cijevi prije betoniranja u šalovane deke i zidove donedavno se je koristilo samo u industrijskim i višestambenim objektima.

As this is one of the most economical execution of electrical installations both temporally and aesthetically, it has become the usual way of performing in smaller private residential buildings. Wall erosion (stamping) and breakdowns are reduced to a minimum, and thus damage to walls and later recovers. In order to perform quality installations on time, the investor must decide before the construction itself for an electrical installer who will be present during the entire construction phase and on time, ie, Prior to concreting, install the appropriate electrical installation pipes, electrical installation junction and distribution boxes. Often people ignore electrical installations before construction, and when the time comes to introduce electricity into the house, a breakdown, drilling, piercing, noise, and dust phase comes, and all this could have been avoided if the electricians were present in time. When installing the pipe, care must be taken to include all segments of the electrical installation that will be carried out.

The pipes must be correctly and in accordance with the saproins of the profession dimensioned and meet the strength and quality protected before concreting so as not to damage them. You also need to pay attention to both bending tips and lengths, and to place the transient boxes in order to facilitate the subsequent easy loading of electrical conductors and cables.

Today, there are plenty of electrical installers on the market, and when choosing, you need to pay attention not only to the price, but also to the prescribed standards and certifications that guarantee that the installation pipes will be of high quality and satisfy the needs and requirements for the appropriate type of electrical installation.

4e-Group d.o.o. with many years of experience and knowledge of its electromotors acquired through the construction sites of entire BiH, from the very appearance of the type of installation, and by constant monitoring of the development of the system of installations, it performs this type of electrical installations quality and, above all, according to the rules of the profession.

Classic installation of electrical installation

Implementation and adaptation of electrical installations with a classical tear-off system and installation of electrical installation wires, cable distribution and connection boxes with gypsum.
Elektroinstalacije se izvode na novim objektima izgrađenim od cigle i adaptacijama, postavljanjem elektrinstalacijskih cijevi, kabela i vodiča u uštemane zidove i deke.

With more modern tools and devices, which electromechanical devices of our company professionally handle, and such operations that are inevitable in the new construction with ease will minimize damage to tearing walls or breakthroughs.

Computer networks - design and construction

Designing computer networks is a complex task that requires first of all careful planning, which must be in line with the needs of the customer.

We design all kinds of networks depending on their purpose, taking into account the available infrastructure and network, the needs of the contractor as well as the location of individual devices within the network.

Network Types:

  • fast ethernet, 100Mbit/s,
  • gigabit ethernet, 1000Mbit/s,
  • networks built using optical or copper cables,
  • computer networks used in industry,
  • connecting remote networks.

Each active network device, whether it's a router, a switch in a modem, a printer, or a computer, is adjusted according to the request of the customer.

In addition, we maintain computer networks designed by us. This includes removing errors that may occur after network construction, maintenance and repair of network devices, and solving problems through remote access.

TV installations and antenna systems


Antenna system with antennas for receiving TV signals is placed on the roof of the building. Antennas for VHF and UHF (terrestrial programs) are placed on the Ansic pole. Antenna column is a steel column of approx. 3m high, which is anchored to the roof with steel rope and anchored screws. The pillar must be connected to the IP installation using a PY 6mmV conductor.

The antenna selection is done according to the receiving channels of the area on which the object is located. The satellite dipole antenna is also mounted on the roof of the building to the associated satellite antenna carriers. The satellite antenna carrier connects to the IP installation.
The satellite antenna is selected according to the satellite it captures and the required strength of the satellite signal. TV signal receivers, converters and amplifiers are placed in the object as close as possible to the antennas.

Distribution of TV installations with dividers

There are several ways to disinfect TV installation, which depends on the network configuration, the requirements of the investor, and the number of TVs needed in the facility. With the diversification of terrestrial programs and CATV divisions, usually the main coaxial cables in the PVC pipes are laid (through housing) through the stairway. Then, the dividers of the TV signal for 1, 2, 3 or 4 branches (which depends on the number of dwellings on the floor) are placed in the storey cabinets. In larger branch divisions, broadband amplifiers are placed on the branches. In the cable housing, a 60 mm distribution box is brought to the TV outlet.

Implementation of electrical installations for intercoms and video-intercom systems

Interphone systems are becoming increasingly used in a growing number of facilities both in large residential and commercial buildings, as well as in smaller family homes, where until recently they were not represented, but by the development of electronics, technology and the lowering of prices of devices, they became truly accessible to everyone in uncertain times, We are witnessing, more and more, the need for security and control over entering the facility.

Video intercoms are used for the purpose of simpler and better communication with people in front of your door, fence, etc. The system consists of a camera call key and audio communication as an outdoor unit, electrical locks (for automatic opening from the indoor unit), and one or more indoor units with audio communication and monitor. In this way you can immediately see if there is if front
your door is one or more people, who is in front of the fence, without having to physically go to the location of that location, and after checking it, by pressing the button to release the electric locks, the input is authorized.

If you have encountered the need for a simple intercom or for the large intercom or video intercom system 4e-Group d.o.o. It is at your disposal for all consultations and suggestions and solutions.

Automatic control systems

The cost of building a family home, apartment or business object is difficult to evaluate accurately. Usually, the estimated value of the construction (the design projection or the contractor's budget) can be predicted, but both rules deviate from the later realized price. The reason for the small or large differences in the final value can be higher, from the errors in the project documentation to the special wishes of the investor and the duration of the construction (irreplaceable is the same inflation, however small). Every old and old property needs more maintenance. Some maintenance work should be carried out at the scheduled time. The average economic lifetime for new construction is approximately:

  • family house of massive construction: 60-80 years old,
  • family house of light construction: 40-50 years old,
  • city ​​facilities with apartments for rent: 50-80 years old,
  • tenants and business facilities in cities: 60-80 years,
  • business and office buildings: 60 years,
  • sales centers: 40 years,
  • industrial facilities 30-40 years,
  • tenants and economic facilities: 80-100 years.

Looking at the overall economic life of the building, we see that construction costs amount to an average quarter of the cost of living. Consequently, part of the savings due to the automation of the building is more than the investment in the automation of the building. Certainly most of the functional costs are due to the heating and consumption of electricity in the lighting of the facility, therefore the KNX / EIB intelligent installation is a good business decision. Long-term can save 30% of operating costs compared to conventional electrical installations, in some cases up to 50%. Investing in an intelligent KNX / EIB installation comes back after 2-6 years of use of the facility.

The most difficult decision for an investor is the choice of equipment or protocol, because automation is highly efficient when we use all the capabilities of the embedded system, and not just a part of them. Systems based on KNX / EIB technology are most suitable for residential and business facilities, however, LonTalk, BacNet and Profibus standards are better for the automation of production processes and large facilities. We must be aware of the fact that more complex systems are more expensive to maintain and less flexible. Required installations for the implementation of the KNX / EIB system are simple, and the subsequent upgrade also does not require a larger operation. The reason is in the concept of the system, where the KNX / EIB equipment connects directly to the BUS line.

Investing in intelligent installations is not only more comfortable and more economical, but contributes to a smaller discharge of polluting gases, as 75% of electricity is produced using fossil fuels.

The present situation of man makes us not to look in advance, but how to put an end to the end, but when we think about the savings that a smart installation brings us in the long run, we see that it is worth paying off to invest in it. For any questions, feel free to contact us in order to find the best solution for your energy-saving and most modern comfortable home.

Optical cables provide extremely fast data transfer between geographically distant locations. Today's Internet would be virtually unimaginable without using this technology. Thanks to the fact that continents are connected by optical fibers, it is possible to access content from the other end of the planet in just a few milliseconds.

Advantages of optical cables in comparison with copper cables are:

  • smaller dimensions,
  • the ability to convey large amounts of information,
  • a little weakening of the signal that allows reaching up to 200 km without signal amplification,
