Device type

Audio intercom. Intercoms with a wired connection, providing only voice communication between the guest and the host. They have low cost, but are not as convenient as video systems, since they do not allow you to see the visitor.

Video intercom. Wired intercoms that allow the owner not only to hear, but also to see the guest. This provides additional convenience and security, however, such models are more expensive than audio intercoms (see above). In addition, not all outdoor panels provide the cameras necessary for video surveillance; and without cameras, the main advantage of such devices is completely lost.

Radio intercom. Intercoms in which communication between the indoor unit and the calling panel is carried out via a radio channel. Such a connection is more expensive than a wired one, but it significantly simplifies the connection: you do not need to drill walls and pull wires. By specialization, models with a radio connection can refer to both audio and video intercoms; about those and others, see above.

IP intercom. In intercoms of this type, the indoor unit and the calling panel are connected to a local computer network and exchange data through it. And some models are generally external calling panels that use a computer or other network device as an indoor unit. Anyway, one of the key a...dvantages of IP intercoms is the extensive possibilities for interacting with various devices, up to controlling curtains, lighting and other smart home components. In addition, such intercoms may even provide the ability to send notifications via the Internet — thus, the user will be able to receive information about visitors anywhere in the world where there is access to the Internet. The intercom itself can be connected to the network both by wire, via LAN, and via Wi-Fi (see "Additionally").

In box

The main components and the number of their copies supplied as standard equipment.

— Intercom. This section specifies delivery options with several internal units that can be connected to one call panel. Such a complete set will come in handy if it is necessary to establish a connection for several subscribers or install internal intercoms to service one subscriber, but at several points (for example, to organize an intercom or deploy equipment in a large house).

With a call panel. The presence of a call panel directly in the intercom package. This option for supplying equipment eliminates the need to buy a call panel separately — the standard call device is most often optimally suited to a given intercom model, while difficulties may arise with the selection of a third-party panel.

— Number of subscribers. In this context, it is implied that several subscribers can be called from the complete call panel, and their specific number is indicated.

Mount

Regular installation method provided in the intercom. This parameter is relevant for models that are not portable (see "Execution"), the options may be as follows.

- Mounted. Installation by hanging on studs, hooks or other similar fasteners. This method is the simplest, besides, if necessary, the intercom can be moved to another place without much difficulty; and there are no obvious shortcomings in the hinged installation. Therefore, this option is used by most stationary (not portable) intercoms.

- Embedded. Mounting, in which the body of the device is hidden in the wall recess, and only the control panel is located outside. The latter is almost flush with the wall surface, due to which the intercom takes up a minimum of space, and also looks stylish and neat. In addition, such a device cannot be thrown to the floor with a careless movement, while mounted models have such a possibility. On the other hand, the installation of built-in intercoms is much more difficult due to the need to prepare a niche, and these advantages are not often key. Because of this, this option is rare, mainly in premium models designed for rich interiors.

Built-in quadrator

The presence of a built- in quadrator in the intercom.

Quadrator is a device for simultaneous display of video signals from several surveillance cameras; the screen is divided into "tiles", each of which shows a picture from its camera. This allows the user to monitor the cameras without switching or missing "pictures" from any of them, and if necessary, the desired "tile" can be displayed on the entire screen. The simplest quadrators are designed for 4 cameras, however, there are solutions for more — depending on the number of cameras for which the intercom is designed (see below).

Note that a video intercom without this function can be supplemented with an external quad, but it is easier and cheaper to purchase a model where the quad is initially provided in the design.

Number of ports

The total number of ports for wired connection of various equipment provided in the intercom; in fact — the maximum number of wired devices that can be simultaneously connected to the intercom.

Keep in mind that this number may be less than the total amount of supported devices. This is especially true in models with the possibility of using additional monitors (see "Connected monitors"): such devices are often connected in series, "chained" and occupy only 1 port. Thus, for example, an intercom for 2 calling panels and 3 monitors can have only 3 connectors — one for calling panels and one for monitors. Note also that the LAN port in IP intercoms (see "Device type") is also taken into account in this calculation.

Maximum call duration

The longest continuous conversation that the intercom provides. Technically, this duration can be unlimited, but in fact, limits can also be set — usually from 1 to 4 minutes. This is primarily due to the fact that in systems with several call panels, a conversation through one of them may interfere with the work of the others. Limitations on the duration allow you to exclude long conversations and possible overlays, and the available time is usually enough to clarify all the necessary questions during one conversation. Also, this feature is useful in case you forget to turn off the connection (hang up) at the end of the conversation.

Half duplex

In this case, half-duplex communication means such a communication format in which the interlocutors cannot simultaneously speak and listen to each other. Only one of them can speak at a time, like talking on a walkie-talkie, where you have to constantly switch from transmitting to receiving and vice versa. In intercoms, such switching can be carried out both with a button and with the help of voice activation: the system turns on the transmission when it hears the voice of the speaker, and switches to reception when it does not hear it.

Half-duplex models are not as convenient as full-duplex models (with the possibility of simultaneous talking), but they are somewhat cheaper.

More features

Android OS. The advantages of the Android OS include flexibility, which allows you to install third-party applications, thereby increasing the functionality of the device. Such applications may include SIP phones, programs that allow video surveillance, and others. But it is worth noting that such devices are not very suitable for the role of using a full-fledged tablet; firstly, most have a stationary location, and secondly, as a rule, the power of intercoms is not so high. Also, various restrictions may be set separately by the manufacturer; this must be clarified separately.

Wi-Fi module. The Wi-Fi wireless communication module is found only in IP intercoms(see “Device type”). This function allows the device to connect to the network wirelessly - this is much more convenient than pulling cables, and the quality of communication is usually indistinguishable from a wired one. Another option for using Wi-Fi is a direct communication to a smartphone or tablet and using such a gadget as a remote control with an external screen; however, such an opportunity is provided relatively rarely.

- Mobile app. This feature means that the device can be operated via a smartphone or tablet with a special application installed on it. Such applications are usually released immediately for both of the most popular mobile operating systems today - Android and iOS; ho...wever, it would not hurt to clarify this point separately. In any case, control from a mobile device can have very extensive functionality (including even the ability to work via the Internet, in some models); and interacting with a device through a gadget that you can always keep with you is definitely more convenient than going to an intercom or other stationary equipment every time.

SIP protocol. The intercom's support for the SIP protocol allows the intercom to redirect the signal from the calling panel through the telephone network to a mobile device, a stationary PBX or a computer with the appropriate software. Such a function may be useful, for example, in an office where there are a lot of visitors, and going up to the intercom every time to answer is inconvenient. Additional SIP capabilities in different models may vary significantly; they should be clarified separately.

- DVR support. The ability to operate the intercom in video recording mode from calling panels or from separate surveillance cameras. In most of these models, recording is not carried out constantly, but only when the call button is pressed or another event occurs - for example, a motion detector is triggered (see below). Video is most often saved to a memory card (see “Card Reader” below). In any case, this function allows you to find out who called the intercom at “inopportune hours”; it can also be useful in other situations - even to restore the picture of an emergency that came into view of the cameras.

Internal communication (Intercom). This function allows you to make calls between intercoms on the same network. Depending on the implementation and settings, there is an addressable intercom, when you enter the number (identifier) of the device on the network to which you want to make a call, as well as options for setting up a general call, when the call goes to all devices on the network. In any case, this function will be useful if there are several intercoms in the network, so you can call, for example, a neighbor.

- Speakerphone. A hands-free function similar to that found in telephones. In this mode, a loud speaker and a sensitive microphone are used for conversation, located in the intercom body and allowing you to communicate comfortably at some distance from the device (up to a meter, or even more). This function is especially important for models with a handset (see “Execution”) - it allows you to talk without holding the handset. But devices without a handset, by definition, operate in a hands-free format.

- A voice message. An analogue of the answering machine function in phones, when the subscriber can leave a message if the owner of the intercom does not respond to the call. The function can be implemented in different ways, but in any case it is similar to the one with the usual expression: “Leave your message after the sound signal...”.

Picture in picture. The ability to display a second image on the intercom screen, in addition to the main image. In this way, you can, for example, check the situation in the visibility range of a surveillance camera without interrupting communication with the visitor via the main video panel. The additional picture is small in size and is usually displayed in one of the corners of the screen.

- Motion Detector. A function that allows the intercom to detect movement in the visibility range of connected cameras and respond to it. The specific method of such a reaction may be different in different models: turning on recording, sending a notification to a user-specified device, sending a signal to an alarm output, etc.; These details should be clarified separately. In any case, the motion detector reduces the likelihood of missing significant events in the field of view of the cameras.

Built-in memory. Built-in memory is found in video and IP intercoms (see “Device type”) and is usually intended for storing data from surveillance cameras. However, the volume of such memory is usually small, and it is usually used only for photographs (for example, to capture the faces of visitors); Video recording, if provided, is carried out on a memory card (see below). In any case, it would not hurt to clarify the operating features of the built-in memory separately.

- Frame. The ability to operate the intercom in digital photo frame mode - when photographs stored in the device’s memory (or stored on a memory card) are displayed on the screen (usually in slideshow mode). A mandatory feature of models with this function is a fairly large color screen - only on it photos will be normally visible; The intercoms themselves are usually video or IP models. The main purpose of the photo frame mode is aesthetic: showing beautiful pictures, the intercom plays the role of additional decor for the number.

Display size

Diagonal size of the intercom's own display.

In modern intercoms, there are displays ranging in size from 2 "to 10" — smaller screens are non-functional, larger ones are unreasonably bulky and expensive. At the same time, you can normally view the image on almost any display from this range — if you lean close enough to it.

With all this in mind, it makes sense to specifically look for a large screen (10 ") if you need to see it normally from a long distance (a metre or more), or if you do not want to strain your eyes once again, peering into a small image. Golden the middle is the 7" display.
