Nowadays, people are trying to provide theirsecurity by any available means. It is terrible to live, knowing that you are not protected in any way. Most of the burglaries come from the fact that any person can easily enter the entrance of an ordinary house. And then - the matter of technology. To prevent this from happening, for some time the entrance doors in the houses are equipped with special devices, with the help of which the tenants can decide themselves whom to let into the entrance. Such a device is called intercom. It consists of four main parts: the call block, intercom, lock and key. The tube for the intercom is an integral part of any intercom. It allows you to establish contact between the visitor and the owner of the apartment. In addition to the possibility of communication, the handset is equipped with elements that provide it with additional features:
- indicator light, which indicates that the system received a signal;
- a lever that allows you to disable the subscriber device;
- ringing tone;
- ringer volume control;
- device to select the melodies of the signal.
The tube for the intercom is usually installed in the apartment of the subscriber and is mounted on the wall at the front door. The intercom is installed at a height not exceeding one and a half meters from the floor level.
Variety of constructions
Depending on the type of intercomdistinguish between audio and video intercoms. The first option allows you to communicate with the guest at a distance and, if necessary, use the special button to open the front door to the entrance. The second type of intercom has a screen on which you can make covert surveillance using an outdoor video camera. On the monitor, you can see the visitor and part of the space in front of the camera, depending on the viewing angle. Handset for intercom is present in both devices. In practice, analog and digital intercom systems are mainly used. There is also a division according to the principle of communication of the call block with the subscriber: coordinator-matrix and direct addressing. The second option provides for a separate button with the apartment number on the call panel. That is why for apartment buildings more often used the first option. In some cases, the tube for the intercom of a particular system may be interchangeable.
Right to choose
When installing an intercom system in the stairwell orin another room, intercoms are already bundled with the rest of the equipment. The customer only needs to choose the type of communication: audio or video, a regular model or a device with additional capabilities. An important role here is played by the cost of equipment. Everything will depend on the chosen system, the country of origin and the supplier. When installing the system in a residential building, an important role is played by the number of apartments in the stairwell, since the total cost of the installation will be proportionally divided between users. There are cases when someone from the neighbors did not have time to connect with everyone. In this case, the service organization may install the subscriber unit. The cost for the tenant in this case will be slightly higher, as additional technical work will be required. During the operation sometimes intercom tube itself fails. The cost of replacement in this case will include the cost of the device and the services of a wizard for its installation and performance check.
Convenience and comfort
Intercom handset is an item withwho have to repeatedly contact during the day. That is why it is necessary to carefully approach the issue of choosing a personal subscriber device. It should be as convenient and functional as possible. For example, the lever to turn off the sound signal is very useful for older people and mothers with small children. With it, you can easily turn off the sound of your device, and no one outside can disturb until the signal is turned on again. Sometimes a standard melody can cause negative emotions and create a kind of discomfort. This problem is easily solved with the help of a special device that allows you to choose a signal that is pleasant to the owner. An important role is also played by the appearance of the tube: color, material, version. The service company or in the trade network always has an offer of choice.
