The intercom is a particularly practical device for identifying a visitor and allowing him to announce his presence. The market offers a huge range of models, but the wireless intercom seems to win all the votes due to its ease of installation.
Functioning like a telephone, but at a short distance, the intercom is an access control device fitted to individual houses and buildings intended to signal the presence of a visitor. It thus avoids the occupant of the house having to leave their home to verify the identity of the visitor and know their intentions. It is also possible to communicate with the visitor in question thanks to the integrated loudspeakers as well as the microphones.
The evolutions on this product are such that today, the intercom can be combined with a security system such as a digicode or recognition by magnetic card giving access to private property, a company or a building. Better still, the video intercom is equipped with a camera and a screen to know the identity of the visitor by seeing his face and his body. It is even possible to have a view of what is happening in the street and the alleys, which is very practical for optimizing the security of the building. In order to better meet the needs of users, manufacturers have devised two categories of intercoms:the wired model and the wireless intercom.
The wireless intercom as its name suggests is devoid of wires. Unlike wired solutions, the installation does not require heavy and restrictive work such as the creation of trenches, which allows it to be affordable in terms of price. As there is no physical constraint, it is possible to install the intercom at any location. However, to ensure its proper functioning, it is essential to respect the distances recommended by the manufacturer and indicated in the instructions for use.
Depending on the models chosen, the outdoor box can be recessed directly into a wall or placed on the surface. Before the final fixing, it is first necessary to carry out some tests to make sure that the connection functions correctly. All that remains is to connect the inner box to the mains. Nothing prevents you from doing the installation yourself since it is simple. Choosing to go through the services of a professional will ensure the reliability and longevity of the solution.
The small scale of the work is a strong point of the wireless intercom. However, this device has some disadvantages. Already, in relation to the distance, it must not exceed 200 meters between the two bases, otherwise the communication risks being scrambled. Indeed, the electromagnetic field has emission limits. Interference from other radio waves can also lower the communication quality. It is for this reason that wireless systems are considered less reliable than wired solutions. And as the device works with batteries or cells, a systematic check of their state of charge is essential.
