Comparison Vtech DM111 vs Motorola MBP160

— Two-way talk. This function provides two-way communication: you can not only hear the baby, but you can also talk to him/her. For example, if the baby woke up late, the parent's voice may lull him/her back to sleep. In addition, two-way communication can come in handy when the baby grows up — a baby monitor with such an opportunity actually turns into a portable walkie-talkie that can be used in games or hiking.

— Camera control. The ability to control the baby monitor camera (refer to "Product type") from the parent unit. This greatly expands the possibilities for monitoring the child's room: for example, if the child got up from the crib and is not in the camera's field of view, you can turn the lens and control what exactly the child is doing.

— VOX mode. A system that reduces the power consumption of the parent unit, and consequently its runtime without recharging the batteries. It can be realized in different ways. For example, the parent unit can be constantly in a kind of “sleep mode” (LEDs are not lit, the display does not show anything, etc.), until the child unit detects any significant sound or the touch mat is triggered (see below); in some models, this mode can be switched on and off manually. Another option is the special ECO mode, which reduces transmitter power and therefore power consumption; it can be activated when the distance betwee...n units is short and significant power is not required.

— Volume control. The ability to adjust the volume of the sound of the parent unit. For example, in a noisy kitchen, the volume can be set to maximum to ensure that you can hear the sound from the speaker, and in a quiet atmosphere, the volume can be lowered to keep relatively soft sounds out of the way.

— Activity light indication. Baby monitors with this function are equipped with a special indicator that gives a light signal if the microphone of the child unit picks up noise in the room. Many models have a gradation of signals: for example, if the child just turned in his/her sleep, one LED is activated, and if he/she started crying, the entire set lights up. Such an alarm usually plays a supporting role, complementing the main speaker of the parent unit; in addition, in such devices, the speaker can often be turned off altogether and the baby monitor can be used in silent mode, with only a light indication.

— Vibration mode. Indication of activity in the child's room (increase in noise level) by vibration of the parent unit, similar to a vibration signal in mobile phones. Similar to light, such an alarm serves as an addition to the main speaker and can be used both in parallel with it, and separately as a silent mode; at the same time, it is more convenient than the light one (see above) — the parent does not have to constantly look at the device, because even without seeing it, he/she will immediately know about the operation. On the other hand, the price of models with vibration is higher.

— Out of range indicator. A special alarm on the parent unit, warning of the loss of communication with the child's unit. Without communication, the baby monitor becomes useless, and even dangerous, because the silence of the parent unit creates a false confidence that all is well. The presence of an out of range indicator will help to avoid such situations. Such an indicator can be visual (light indicator, signal strength indicator) or sound.

— Card reader. A card reader allows the device to work with removable memory cards — usually SD or microSD; the specific format and subtype of compatible cards needs to be specified separately. However, this function provides various additional features anyway. Memory cards are intended for storing recorded videos and photos (refer to "Baby unit"), downloading melodies for a music box, software updates, etc.

— Headphone output. A connector (usually a standard mini-jack 3.5 mm) that connects headphones to the parent unit and can be used to hear all sounds through the headphones. This feature can be useful, for example, if it is necessary to maintain maximum silence and any excessive sounds in the location of the parent unit are not desirable at all, or in a noisy place where there is a risk of missing a signal.

— Low battery indicator. The indicator that shows when the batteries in the parent unit are low. Usually, it warns in advance of the need to change or charge batteries, which reduces the likelihood of an unexpected failure of the baby monitor at the most inopportune moment.

— Timer. A kind of analogue of an alarm clock: after a specified time, the parent unit gives a signal, and parent will not miss the right moment (for example, when it is time for the baby to get up).

— TV connection. This provides the ability to watch the baby unit's broadcast on a TV, because the own screen of the baby monitor, even in the largest models, is very small (refer to “Screen size” for details) and not even comparable to the most compact TVs. In addition, the connection to a TV makes it possible to record video even if the baby monitor itself does not have such function (see below for more information on recording).

Parent unit mounting type — with some exceptions, they are designed to be carried with you all the time.

— Neck strap. A strap that can be worn around the neck to carry the parent unit. This attachment is convenient because it does not depend on clothing (unlike a belt) and does not involve the hands (unlike a wristband).

— Wristband. A wrist mount, similar to a wristwatch. Its advantage is that the parent unit is in view most of the time, simply put — it is most often in front of the eyes. This is especially important if you use light indication. On the other hand, the dimensions of even compact parent units are considerably larger than a wristwatch, which may cause some inconvenience.

— Belt clip. Mounting on a belt is convenient in that it frees the hands. On the other hand, it puts forward certain requirements for clothing: it must have a place for attaching a clip and not be too light, otherwise the weighty parent unit will pull it off.

— On the wall. This feature is useful if you have to sit in one place for a long time — for example, work at a computer: you can fix the parent unit in the most visible place. In baby monitors, mounting exclusively on the wall is practically never found; this option is in addition to one of the three above, most often to a belt clip.

It should be not...ed that in fact, the convenience of mounting depends not only on the above features, but also on your personal preferences.

The country of origin of the brand under which the product is marketed. Often indicated by the nationality of the company or the location of its headquarters. At the same time, the actual production capacity of the brand often differs from the country of origin.

It should be noted that the quality of products depends not so much on geography, but on the peculiarities of the organization of processes and quality control at all stages of production. Therefore, national prejudices regarding brands from certain regions, as a rule, are not supported by anything. It is necessary to pay attention to the country of origin of the brand only if the task is to fundamentally support or bypass the manufacturer from a particular country.
