Modern slang names for cam or the dom ru module itself do not change the essence of the purpose of this equipment. Although the abbreviation CAM means “conditional access module,” people spell it differently in search engines. The main thing is that this device solves the problem of convenient viewing of high-quality digital television without adding unnecessary wires. CAM modules themselves began to be produced in Europe back in the 90s of the last century. Due to the existing monopoly in production, one EuroCAM platform was formed. The only difference between the manufacturers was in the software. Connecting and setting up the cam module is very simple, you just need to follow the instructions of the operator home ru.
What it is?
This is a small electronic device for watching HD quality digital television. The Internet provider began offering its subscribers a House ru card on TV already in 2013. These CAM cards are inserted into a special “carriage” (slot) that serves as an adapter for installation in a DVB tuner (set-top box). Therefore, modern TVs use devices with built-in digital tuners for access cards. If you have a DVB tuner installed on your TV, you can use this technology. If not, you can buy a TV set-top box separately. Connect your home TV via the Movix app. And the application will help you with choosing movies and shows.
Due to the absence of additional wires when connecting CAM technology, interference on the TV is eliminated. Without changing or buying additional equipment, we get HD television quality. You can watch digital even on an outdated TV, as long as it has a built-in tuner. You will also need a Cl slot in which you will need to place an access card. These CAM cards can be purchased from your provider and are customizable. Watch TV anywhere convenient on any device, smartphone or tablet.
How to choose an antenna board
Terrestrial television broadcasting is the basis for the emergence of TV technologies, but still does not lose its relevance. In recent years, satellite and IPTV television has been actively developing, but a huge part of the audience is not yet ready to give up the usual inventions. Broadcasting has one main drawback - the need for a coverage area.
The problem of a weak signal can be solved using special devices. Which antenna boards are best? It is important for users to choose a high-quality device, because the quality of the image displayed on their receivers depends on this.
For various reasons, the signal may deteriorate, and then the image on the screen begins to snow or disappear altogether. Before purchasing a board, you must consider the following nuances:
- Distance from the TV to the nearest TV tower. The maximum distance usually reaches 150 km, but some devices may have higher characteristics. There is also the other side of the coin: the signal can be bad even at a distance of 10 km from the translator. Much depends on the type of terrain and the presence of obstacles in its path. Installing a high-quality active board is the right decision in this case.
- The frequency range in which the device will operate. Wide-range designs are superior in performance to devices with a narrow focus.
If the user has decided on the choice of antenna, he can proceed to studying the active components. The main characteristic of electronic boards is the gain, which is measured in decibels. Passive antennas can be used when the distance from the TV to the repeater is no more than 10-15 km. Excessively high gain may negatively affect digital reception.
Models with high power levels can produce unnecessary electromagnetic interference, the effects of which will appear as white snowflakes on the screen. Using a special table, users can make it easier to select boards for SWA equipment. It shows the parameters for each type of equipment, as well as gain factors and distances to signal sources.
Buying a suitable electronic board is half the battle; you will need to choose the right installation location. The most suitable option is installation on the receiving structure or at a short distance from it. A place near the TV is a bad option, as unnecessary noise will begin to appear and the image will become less quality. The active component is powered via a coaxial cable from an antenna or receiver, or through a separate unit. Signal amplification devices can be equipped with special protection from adverse weather conditions; they are not afraid of electromagnetic interference.
Advantages and disadvantages
Modern devices themselves are available in two versions:
- Operating without a card.
- With the mandatory installation of a smart card from home ru.
In the first case, it works due to the programmed access keys in the slot itself. The second option is used by the provider Dom ru. And the operator writes the keys into the access card itself. It looks like a regular plastic card. In the card solution, the TV tuner decodes all closed channels according to the signed contract and the package of TV channels connected by the subscriber. When watching TV shows through the module itself on a laptop or smartphone, switch between devices and choose what you like.
The most profitable option is to rent a CAM module from the Dom ru operator.
When purchasing the most modern TVs and connecting, for example, Ultra HD, subscribers do not need a new decoding device. Simply install your CAM module into the slot of the new TV. The module independently scans your card and configures all available channels. If you have a receiver, then you will have to buy a new TV set-top box. Connect movix smart TV and receive installments for 24 months when purchasing a tuner.
No additional equipment, extra wires or sockets are needed. They just installed or hung the TV and nothing more. Your long-standing admiration for yet another beautiful DVD player remote control will be replaced by the relief that when using CAM, one TV remote control is enough to connect.
This little thing will bring a lot of relief in everyday life.
The cost of the CAM module is several times less than the receiver. There is no difference in the quality of the films and programs you watch and the provision of services to you. The only differences are constructive, functional and aesthetic. After downloading and connecting to television, the application will learn about your interests and help you next time with finding your favorite shows and movies.
Types of electronic boards
An amplification module is necessary for better reception if the TV is located at a distance from the nearest TV tower. Before deciding which antenna board is best, it is recommended to study all types of amplifiers and become familiar with their characteristics.
Equipment for signal amplification stands out for its diversity; an inexperienced user will quickly get confused when choosing the most suitable product. Based on functional features, active modules can be divided into several main types:
- Models operating in a wide range. They are most often used for external lattice-type structures installed on special masts.
- Devices operating within a certain range. Devices for MV devices have lost their relevance, since “digital” is available exclusively in the UHF.
- Devices configured to operate with multiple bands. They have the ability to catch signals arriving simultaneously from several sources and transmit them to one TV receiver.
Receiving designs known as “Polish antennas” are very popular among consumers. They are usually equipped with active components of the SWA type. The TV antenna board is configured to operate in the range from 49 to 790 MHz. When choosing an active module, you should pay attention to the two most important characteristics: noise figure and gain. The first characteristic should have a minimum value, but the maximum gain does not always bring much benefit. The main thing is that the TV produces a high-quality and clear image, so you should select an amplifier taking into account specific conditions.
Based on reviews from Russian users, a rating of the most reliable and high-quality devices was compiled. Among them, LSA devices used for Locus devices stand out. The receiving structure can fail for various reasons, most often bad weather conditions become a negative factor. Using an LSA amplifier, the subscriber is able to extend the service life of receiving equipment and improve the level of the received signal.
The ranking of popular boards also includes products from the manufacturer Alkad and Terra. The first brand produces products with two or four contacts, thanks to which you can set up signal reception on several TV receivers at once. The Lithuanian manufacturer Terra produces multi-pass products that provide the ability to combine several signals into one. Most active components are equipped with a power module that connects to a standard electrical network or receiver. Built-in products are compact in size; modern outdoor units are small in size. You rarely see bulky modules on transformers anymore, since they are no longer produced.
Setting up the cam module
Connection and setup should only be done with the television receiver turned off:
- All actions must be performed in strict accordance with the operating instructions for the TV.
- Insert the house ru smart card into the TV so that the side with the chip is in front and the logos on the card and on the module are directed in the same direction
- Turn on the television receiver.
- Set up the TV in accordance with its operating instructions.
- After turning on the TV, information about the presence of CAM will appear on the screen.

Questions about the CAM module
1. Will there be any difficulties when recording TV programs when using a CAM module and a TV with a built-in recording function (attached DVD with a recording function)?
Answer: depends on the TV. Some do not allow you to record broadcasts or add watermarks. It all depends on the circuitry of the TVs; in most cases this will be possible.
2. I have a CAM module installed. The next time you turned on the TV, the TV program appeared only on some channels. Why?
Answer: Auto-search for channels on your TV. The TV program will appear on all channels, with the exception of TV Sale, which does not provide the TV program. Some TVs (Sony, Samsung, others) have an “auto-update channels” function - disable it.

CAM is an electronic device that is used as an adapter of a specific encoding system to all conditional access interfaces (the so-called common Interface) in receivers and televisions. The Dom.ru CAM module for digital television acts as a guarantee of subscriber access to encrypted media content.
KAM module - what kind of device is it?
When purchasing a new TV, it is better to give preference to a model that already has a built-in receiver.
New TVs have become even more convenient to use and in order to watch cable or satellite channels, you no longer need to connect additional external equipment to them. The task of the tuner built into the television receiver is to receive streaming broadcasts and decode the signal, which comes in different formats.
For full operation, the system requires support, and this role is taken on by the KAM module - a compact device that converts the digital stream so that the TV can perceive these signals. The user contacts the operator of the service provider, purchases a special smart card, and it opens access to previously blocked TV channels.
When purchasing a new TV, it is better to give preference to a model that already has a built-in receiver and a slot for the module being described. This electronic device has the following advantages:
- digital and previously blocked channels are opened, and with high image quality;
- affordable price. It is cheaper to acquire a panel with a module than to later purchase a device that provides the same capabilities, for example, an external digital set-top box;
- easy to install and configure. All the TV owner needs is to buy a “smart card,” attach it to the module, insert it into the slot and configure the channels, which takes a few minutes. The procedure is similar to inserting a memory card into a smartphone;
- compactness. The module is slightly larger in size than a regular plastic card; moreover, it is “hidden” in a slot called CI, so it does not take up free space next to the equipment. Yes, and you don’t need to connect it to an outlet like a TV set-top box, since it is powered by the TV;
- To control channels, the “native” remote control is used.
