Nowadays, people are trying to ensure their safety by any means available. It’s scary to live, knowing that you are not protected in any way. Most apartment thefts stem from the fact that anyone can enter the entrance of an ordinary house without hindrance. And then - a matter of technology. To prevent this from happening, for some time now the entrance doors in the houses have been equipped with special devices with which residents can decide for themselves whom to let into the entrance. Such a device is called an intercom. It consists of four main parts: a call unit, an intercom, a lock and a key. The handset for the intercom is an integral part of any intercom. It allows you to establish contact between the visitor and the landlord. In addition to the ability to communicate, the handset is equipped with elements that give it additional features:
- a light indicator that indicates that a signal has been received through the system;
- a lever to disable the subscriber device;
- sound signal of a call;
- ringer volume control ;
- device for selecting ringtones.
The handset for the intercom is usually installed in the subscriber’s apartment and is mounted on the wall at the front door. The intercom is installed at a height of not more than one and a half meters from the floor level.
Variety of designs
Depending on the type of intercom, audio and video intercoms are distinguished. The first option allows you to communicate with the guest at a distance and, if necessary, use the special button to open the entrance door to the entrance. The doorphone of the second type has a screen on which, using an external video camera, you can conduct covert surveillance. 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 separation according to the principle of communication between the call block and the subscriber: coordinate 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 the first option is more often used. In some cases, the handset for the intercom of a particular system may be interchangeable.
Right to choose
When installing an intercom system in an entrance or other room, intercoms are already included with the rest of the equipment. The customer only has to choose the type of communication tool: audio or video, a conventional model or apparatus with additional features. An important role here is played by the cost of equipment. Everything will depend on the selected system, country of manufacture and supplier. When installing the system in a residential building, the number of apartments in the staircase plays an important role, since the total cost of installation will be proportionally divided between users. There are times when one of the neighbors did not have time to connect with everyone. In this case, the service organization can perform the installation of the subscriber unit. The cost for the tenant in this case will be slightly higher, as additional technical work will be required. During operation, the intercom tube itself sometimes fails. The replacement price in this case will include the cost of the device and the services of the wizard to install it and check the operability.
Convenience and comfort
An intercom handset for an intercom is an item that you 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 mute switch is very useful for older people and mothers with young children. With it, you can easily turn off the sound of your device, and no one outside can disturb you until the signal is turned on again. Sometimes a standard melody can cause negative emotions and create a kind of discomfort. This problem can be easily solved with the help of a special device that will allow you to choose a signal that is pleasant to the owner. The appearance of the tube also plays an important role: color, material, embodiment. The service company or the distribution network always has an offer of choice.
