Glossary

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.

Screen resolution

Resolution of the display installed in the intercom.

All other things being equal, a higher resolution provides a smoother and more detailed image, but it does affect the cost of the screen. In addition, all the benefits of high resolution are lost if the camera you are using does not support it. In general, this parameter is secondary: it is selected by the manufacturer based on the screen diagonal and the general functionality of the device, and for many screens it is not indicated at all - it is believed (and quite reasonably) that the resolution is in any case sufficient for its intended use. Therefore, there is no point in chasing a Full HD screen ; an HD display, or even an SD one, will be enough.

Touch buttons

The presence of touch buttons in the design of the intercom.

Unlike mechanical ones, such buttons do not need to be pressed in — they do not work by pressing, but by touch, which is somewhat more convenient. However, the main advantage of touch panels is still in a neat appearance and resistance to dirt. Such panels look modern and technologically advanced, they do not have protruding buttons that make it difficult to clean, and there are no gaps between the buttons and the panel itself, where dirt can accumulate. However they are somewhat more expensive and more difficult to manufacture than push-buttons; this is imperceptible to the average user, but is a disadvantage for manufacturers. That is why sensors, for all their advantages, have not supplanted traditional buttons.

Display support

The number of additional monitors that can be connected to the intercom at the same time.

This function is relevant only for video-enabled models — video intercoms and IP intercoms (see “Device type”). In such models, the intercom itself is called a monitor — an indoor unit with a screen. This paragraph indicates how many additional indoor units can be connected to this model. The need for such a connection arises in cases where access to the security system must be provided from several points at once — for example, in a private house on several floors, where it would be inconvenient to run from floor to floor to the intercom. In this case, intercoms with access to 3 monitors, 4 monitors or more are appropriate.

Note that the format of multiple monitors working together may be different, see "Connection Type" for more details.

Consumption (standby)

The amount of energy consumed by the intercom in standby mode. In this mode, the device is energized and is in a state of readiness to receive a call; no functions are used, and the readiness itself does not require a lot of energy. Therefore, the value of this parameter, usually, is rather low, and you should pay attention to it only if you fundamentally strive for maximum efficiency of the installed equipment.

Consumption (during operation)

Power consumption of the intercom in the operating mode. Usually, this item indicates the value for situations where the device's functions are used to the fullest — in particular, when the display is on and the speakerphone is on (if any, see above). Note that the consumption in the operating mode rarely exceeds 20 W, so in most cases it is more of a reference, and not a practically significant parameter.

Operating temperature

The temperature range at which the intercom is able to work normally.

If the device is installed in a residential area or office, you can not pay much attention to this parameter: the temperature in such an environment rarely goes beyond +18 ... +25 °C, such values are normally tolerated by any intercom. But if the device needs to be placed in a "non-standard" microclimate — for example, an unheated warehouse, where conditions do not differ much from outdoor ones, or a production workshop with a high temperature — you should make sure that the chosen model can normally endure such conditions.

Separately, we note that even the most “heat-resistant” intercom cannot be exposed to prolonged exposure to sunlight.

Product type

The type of call panel that the intercom is equipped with.

— Audio. Call panels that provide only voice communication, without video. The only type of panels available for audio intercoms (see "Device type"), however, it can also be found in the configuration of video models — in the expectation that voice communication may be enough for the first time, and the user may want to choose the video panel on their own .

— Video. Call panels with built-in cameras capable of transmitting not only sound, but also video to the intercom. They are found in all varieties, except for audio intercoms (see "Device Type"). Separately, it can be quite difficult to choose a video panel compatible with an intercom — it is much easier to buy a ready-made kit; Therefore, such kits are very popular nowadays.

Mount

Call panel installation method.

Mounted. Installation by hanging from fixtures placed on a wall, door frame, or other suitable location. This method is quite simple, besides, it allows you to relatively easily change the location of the device. On the other hand, it is less reliable than embedding, and it is easier for hooligans or thieves to rip such a panel from its attachment point.

Embedded. Installation in a niche in a wall or other surface — in such a way that only the front side of the device is outside. and any movement of the device is also fraught with serious difficulties. Nevertheless, it also has advantages: it is almost impossible to remove the call panel from a niche without a special tool, and even with tools, this task takes time and effort.

— Mounted / built-in. This category includes outdoor panels that allow both of the installation options described above. Thus, the user can independently choose a method, depending on what is more important in this case: ease of installation or its reliability.
