Rating of the best intercoms for 2022

The population of the planet is learning to live according to new safety rules to prevent infection with a viral infection of various strains. When human life is at stake, civilization uses all available measures to prevent the transmission of infection. One of the important requirements of sanitary discipline is the exclusion of close contact with a potential carrier of the virus. There are not only permissible communication distances, but also additional protection measures.

An excellent insulating tool is the presence of transparent soundproof partitions in public places:

• points of social security and protection;
• banks;
• auto and railway stations;
• subways;
• airports;
• checkpoints;
• auto-filling stations;
• box office.

The passage of time also affected the business sector. Face-to-face meetings and conferences are moving into the phase of remote communication, which requires high quality, fast technologies, and innovative solutions. To facilitate communication between people, the intercom systems of the latest modern developments came to the rescue.

What intercoms are

All systems for voice communication can be divided into the following types according to the types of communication:

1. interphones based on the principle of telephone communication;
2. intercoms, use the principle of loudspeakers, this also includes emergency communications.

Types of equipment

Simplex

Broadcasting occurs only on one side, when switching to reception, you can listen to the client's response.

duplex conversation device

The equipment makes it possible to simultaneously perform tasks:

1. talk;
2. listen.

When the device is connected, one's own speech is heard, plus the audibility of the conversations of the associated subscriber unit is available.

half duplex

The automatic system works on the principle of disconnecting the interlocutor from the transmission mode at the end of speech and switching to reception. Depending on the required subscriber capacity, a device with a given number of connection channels is selected.

Systems can be expanded by purchasing additional customer consoles.

Multichannel devices

The simplified 1+1 dialogue system is not suitable in cases where a number of called parties are served.To solve such a problem, a switch is required, to which both the main console of the intercom system and each individual client unit are connected. Devices of this type are intended for the number of subscribers from three and more.
The connection occurs through the selection of a button on the main panel, in some cases an additional hands-free function is used. A similar option is relevant at the gas station.

How to choose the right intercom

The purpose of the system is critical.

The dialogue format cashier-client or passenger-cashier can be intended both for one subscriber - a bank, pharmacy, service center, and for a group - gas stations.

To connect the director-secretary, stations are intended with the possibility of subsequent communication between the secretary and the heads of departments.

Wired or not

Laying the cable is a costly and time-consuming part of preparing the system to go into operation. Initially, you need to decide on the models of devices - whether they will be wired or not.

Criterias of choice

Having solved the issue with subscriber capacity, it is important to take into account the following system parameters:

• sensitivity setting;
• volume control;
• no loss of words and phrases when switching modes;
• the possibility of recording negotiations;
• network Internet management;
• availability of additional inputs and outputs;
• the ability to connect a headset;
• Speakerphone;
• resistance to weather factors (with external placement of the unit) is indicated in the characteristics of IPn1n2, where n1 is the level of protection under mechanical stress, n2 is moisture resistance;
• confidentiality of negotiations;
• guarantee period;
• equipment.

Errors when choosing

Do not purchase a machine with functions that will not be used.
It is necessary to decide in advance the issue of the subsequent additional purchase of software and additional blocks, is it not cheaper to take everything in the kit.

Background noises present at train stations and airports are a big hindrance not only for passengers, but also for cashiers working in a noisy shift environment. The ability of negotiation models to dampen volumetric noise, ensuring the clarity of dialogues, is characterized by the parameter of confident system operation.
