Today, the entrances of most multi-storey buildingsequipped with intercoms, however, there are exceptions - at home, where this is not even thought of. But it is worth paying attention to the fact that the intercom will allow solving a number of problems at once. First, you can rid yourself of a society of unfamiliar or suspicious personalities. If you forgot the key to the door at the entrance, then you do not need to ask neighbors for help and freeze in the cold. Let's see how the installation of the intercom goes by its own hands. Believe me, this is quite a feasible task for everyone.
First, let's look at the basic concepts.Here everything is extremely simple. There is a calling device that is installed outside and serves to communicate with the owner of the apartment. There are both one-and multi-subscriber. Modern advanced systems allow you to install various additional functions, for example, a telephone, an access control system, etc. In addition, there is a doorphone that is installed inside the apartment or at home. As you can understand, the device is intended for dialogue with the visitor. In the simplest solution - this is a normal handset, as in the phone, and in an expensive version it can be a video intercom, allowing you to see not only the interlocutor, but also the place near it. This allows us to assess the situation and make appropriate decisions. As you can see, all this is very convenient, although it's not only in comfort, but also in safety.
In order to install the doorphone yourselfpassed without problems and violations, you will need to acquire the necessary tool. As a rule, all this is already available for most men, but something will have to be bought, especially as it will be very useful in the household. Well, you can ask for something from a neighbor or friend. First, you need to have a drill, insulation, as well as a knife and a screwdriver. Also get a pack of alabaster, you do not need much, just a few kilograms will suffice. You will also need dowels and self-tapping screws. It is advisable to carry out all work in gloves, so you will avoid ridiculous wounds. Of course, you can buy a nozzle for a drill, which will allow you to perform wall shattering, but often home masters do without this tool and cope with cheers.
After you have acquired the necessarytool, you need to buy something with which, in fact, we will work. In our case, this is the intercom. This can be a budget option, consisting of the most ordinary audio tube and external device, but most today prefers to pay a little bit more and buy a video intercom. The principle of its operation is exactly the same, but the kit, in addition to the audio-tube, includes a base with a screen, as well as video eyes. The latter is installed directly on the front door instead of the usual eye. To do everything right, you need to pay attention to the marking of cables. Typically, they have a different color, which will help you to connect the system consistently and do not confuse anything. It is possible to say with confidence that for a multi-storey house the simplest door phone model is the best. It is desirable that the installation be carried out collectively, by all the entrances. As for the video intercom, this is an excellent solution for a dacha, private house or cottage.
Any serious undertaking is realized only if,when you decide on the installation location. In our case, we need to at least approximately estimate where the tube in the apartment will be located. In principle, it can be almost any place. As practice shows, most often an audio device is mounted near the entrance door. Of course, installing a doorphone in an apartment involves laying a cable. And this, perhaps, is the most difficult. Here it is important to remember that the cable length should not exceed 40 meters, as the signal will decay and, as a consequence, it may completely disappear. First of all you need to open the flap on the stairwell and find there the cable that comes from the external device. Next, you need to connect this end to the twisted pair, which is done to extend it. Next, you need to make channels in the wall, along which the cable will go to the apartment. After the laying of the wire, the channel is laid with alabaster and shpaklyuetsya.
There are similar options that do notfor example, cable routing through corrugation or in plastic cable channels, but it is not always so easy to realize as we would like. The first option is suitable only when the tube is mounted in close proximity to the door. In this case, the channels are laid along the door frame. As for the corrugation, this refers to the cable that is in the front. All this is done to protect against mechanical damage. Do not forget that undesirable sagging wires, as well as cracks. Take care not to have a power cable next to it. In any case, after the purchase of the product, you will receive a bundle, where, actually, the connection scheme is included, but the way you decide to go is another conversation. But on this installation of the intercom in the apartment does not end, so let's go further.
Compared with the cable laying, this stage to youwill seem like a child's puzzle. Here all the work is done extremely simply and very quickly. First, make notes on the place where in the future there will be fastenings. Then, through the appropriate designations, make holes in the wall. In the holes obtained, insert dowels of the appropriate size. Then you just need to screw in the screws and install the intercom in its place. By the way, do not forget that before that you need to connect all the wires. And one more thing about the electrician: do not forget to power the 220 V cable while connecting the external and internal devices. If you did everything in order and right, then the intercom should earn. If the device does not turn on, then, most likely, you made a mistake at one of the stages. In this case, you have to start all over again, although do not rush to get the wires out of the wall. First, check the connection in the shield, as well as the serviceability of the device. I would like to note that the installation of intercoms in the house today is worth a lot. The amount can fluctuate in the range from 5 to 10 thousand rubles (taking into account the materials), therefore, having done everything yourself, you can save a lot of money.
There are several fundamental differences.For example, it is worth choosing not a audio, but a video intercom, as it is more preferable. Consequently, there are new nuances in the installation. The indoor unit is installed outside the door, although you can choose any other place. The outdoor unit is mounted on the other side of the door or fence. But here you need to take care of the presence of a visor that protects the device from moisture, bright sunlight. Correctly set the angle of rotation. Make it necessary so that you clearly see the person and the environment. We can say that the installation of the doorphone by itself is half done, it remains only to connect the indoor and outdoor unit. The main difference is that it is better to lay the cable under the ground. The optimum depth is 40-55 centimeters. By the way, the wire is not included in the kit, it will have to be bought. But it's not difficult, get a standard 4-wire shielded (4x0.22). And all will be well.
I would like to note that the installation of accessdoorphones takes quite a bit of time, but if you go somewhere wrong, then a lot of effort will be spent on reworking. It is worth to draw your attention to the fact that not everyone has a socket near the door in the hallway, where an indoor unit is installed. Without it, you have to pull the 220 V wire and connect to the system. Pay special attention to this moment. If you repair, do not be lazy - put the outlet. When installing the caller, special attention should also be paid to the quality of the fastening. This is due to the fact that everything in our country is different, so it can simply be stolen. Do not forget that the installation of multi-apartment doorphones is slightly different. There must be a special distributor, which will help the visitor to get to the apartment where he needs.
As you can see, installing a doorphone with your own hands -it's not so difficult as you might think. Nevertheless, you will save decent money, the same 5 000-7 000 rubles can go to other needs, and you will have a new tool, and experience too, which is much more valuable. It is not necessary to do everything alone. Invite your neighbors and do an excellent team work. In this case, several people will wall the wall, others lay the cable, and the third will cover the channels with alabaster. Of course, the installation of the doorphone will be done by each individual, depending on the preferences of the owner of the apartment, but the rest of the work is much faster and more fun to do together. Well, that's all about the manual editing of the door phone.
