Light electrical and communication systems are backbone systems in a building, which is the system of management, transmission and information processing of agencies, companies and enterprises. TheExtra Low Voltage System, also known as the Communications System, has a great position and role in the operation of a unit. Light electrical system – communication includes the following items:
- Security camera system, alarm, anti-break-in,…
- Internet infrastructure, Wifi, Server, Lan, computer, printer,…
- Analog or IP inter-call center system
- Notification sound system, multi-zone audio,…
- Card locking system from the hotel,…
- Light electrical and lightning-resistant system
- Analog AND IP TV systems
- Issues to keep in mind when installing a light electrical system
The following we will go into detail each specific item in the light power system – communication
1. Security camera system, alarm, anti-break-in,…
Security camera system, surveillance camera is a small part of the light electrical system in the building. There are two types on the market today: analog technology CCTV and IP technology CCTV. IP technology is more advanced and advanced than analog technology. However, depending on the needs and economic conditions, to choose the right system.
Security camera systems using analog technology require the following minimum equipment: Analog Camera Recorder, Storage Hard Drive, Analog-type CCTV, camera view display (be it a TV or computer screen), A recording and monitor connection cable (VGA or HDMI cable), If you look through a computer or phone network, you need to add an installation location that must have internet (the carrier’s Internet plan or 3G or 4G wireless transmission line is possible). Signal cables are very diverse, from coaxial cables to network cables, ADSL cables are all possible.

About lan and server: decentralize the internal lan network system and server to share and manage the shared data warehouse of agencies, businesses and organizations to ensure the system operates smoothly, quickly and optimally, saving maximum interaction time.
This is the core and the most important part of a light electrical system. Without this core, the light electrical system would become monotonous, discrete, lacking in system and no longer efficient.
3. Analog or IP internal call center
system is an indispensable part when it comes to light power system in the project. This system is often used in factories, companies, businesses with many office personnel (usually more than 10 people need to communicate with each other regularly). In state agencies, in banks, schools, hotels, resorts… It is also common to use this internal telephone system.

This system brings a lot of utilities to the manager, in order to save time sending general information to a certain group of customers, such as notifying customers who are in the restaurant area or customers in a certain zone A or B, without affecting customers other areas or areas or floors in the same space.
In addition, currently, the works require a fire protection approval design, all require the investor, the managing unit to install this multi-zone notification sound system, combined with the automatic fire alarm center cabinet so that when there is an incident or explosion, the fire signal will be notified to customers in the area. through this multi-zone notification sound system. The system can also save pre-recorded newsletters, depending on the problem, the level of danger that broadcasts the appropriate notification.
This system has not a large investment cost, currently it is mandatory to be in the fire protection system, so investors, the managing unit depending on their needs and investment limits choose the appropriate configurations.
5. Card locking system from hotel
Lock card from hotel apartment is usually installed in hotel rooms, resort apartments. This device is also part of the light electrical system.
The goal is to manage guest entry and exit hours through management software. In addition, installing a card lock system from the apartment hotel helps the management unit, the project investor save the cost of electricity that customers use, the reason is that this card is both used to open the room door and to plug into the card switch, the power system in the room is activated. When going out by default, the customer must bring the card so that when returning to use the same card to open the door of the room, create the habit that every time the customer will withdraw the card to carry or send at the front desk, and so the electrical system in the room also automatically turns off. This card is installed separately for each room door.
6. Light electrical and lightning-resistant system for
light geogeorical system requires soil resistance to be less than 1 Ohm to meet the requirements and effectively grounding. Since light electrical systems include electronic devices, IC’s and chips are very sensitive to current, so the leakage must be grounded and drained completely to ensure the safety of the device.

Next is lightning transmission protection for light electrical system
This is a system against lightning pulses spreading by power cables, coaxial cables providing television services or reinforced steel fibers of fiber optic cables providing Internet signals. These cables on the outside pull into the building; when lightning hits columns, pillars or lines outside the building, the lightning pulse will transmit with these cables affecting the light electrical equipment in the building causing severe damage.
Therefore, it is necessary for transmission lightning protection devices installed on the signal supply line into the building to ensure the safety of the light electrical system.
There are also lightning filter cutting devices installed on 1 phase and 3 phase power lines.
7. Analog television system and IP TELEVISION
System analog television system and IP Tv is an item in the light electrical system of the project. In the past, we used analog television systems of suppliers such as VTV cable, cable SCTV, CMC river collection,… Now that technology is evolving, the television system is evolving as well. Analog technology now switches to using IP television technology of internet service providers such as VNPT, Viettel, FPT. VNPT has My TV, Viettel has Viettel television, FPT has FPT Play.
There are also online TV applications, just A TV connected to the network, download the application, then enjoy high-quality television with a variety of channels from local, domestic to foreign. These TV apps have to pay third parties, meaning users pay directly to the company that provides the app. The most powerful and used app today is Netflix, which is popular in more than 150 countries worldwide.
The above are all the basic problems of light power system in a project.
