The unit that stands in the children's room represents a small video camera with a microphone, and the parent unit is a kind of receiver-monitor, on the screen of which a picture is displayed that the children's camera shoots. Also through the speaker you can hear all the sounds that the microphone is transmitting. Depending on the model, there are some limitations on the maximum distance for good video and audio, on average this distance varies from 90 to 150 meters in the open space. The most budgetary and simple video monitors have a large zone of action - up to 50 meters and show black and white images of the monitors. Advantages of such models is that the screen at the parent block is large enough, its diagonal can be up to 5.5 inches, moreover it can be used as a regular mini-TV both at home and in the car. For these purposes, the monitor has a special slot for you to connect a public antenna, as well as a personal telescopic TV antenna and an adapter so that you can connect the monitor to the car's on-board network. If you talk directly about the main function - observation of the baby, then follow that it is the monitor's dimensions that make the baby monitor less comfortable to use. If you want to go somewhere, then you will need to carry this monitor of considerable dimensions, the weight of which reaches 2.7 kg. Modern baby monitors in this matter are more perfect. Now the mom's block can fit on the palm and it weighs only 300 grams, so carry it with it is not any labor, you can hang it on your belt (for this purpose there is a special clamp) or hang your neck (for this there is a special lace or eyelet for the lace). In such a monitor, there is a liquid crystal display, the diagonal of which is only 1.8-4.2 inches, but it provides a color image of excellent quality: with a good color, angle of view, brightness and contrast. Due to the fact that infrared technologies are used, the baby monitor can work freely even in total darkness. When twilight comes, the light sensor that is built into the camera automatically switches it to night vision mode.
When this function is turned on, a black and white image of objects located at a distance of two meters from the camera is displayed on the monitor. The video monitor becomes more functional when external devices can be connected. If you want, you can connect various players, a video recorder, a TV, a computer and a radio to the AV input of the camera, so you can watch various programs of the program, listen to music and radio, while watching the baby. Even when a camera shows a film or an audio source, the camera does not turn off and goes on working all the time. If there are even the slightest sounds in the baby's room, the baby monitor will immediately switch to voice transmission and the image of your baby. Any devices can also be connected to the monitor via the AV output. For example, if you connect your unit to a TV, you can monitor your baby from the TV screen. And if the TV is equipped with such a function as "Picture in Picture", then it is possible to observe the child and watch TV at the same time.
If you connect a monitor to a VD recorder or a VCR, you can record a video of what is happening in the zone of your control.
How to record?
We all know that very often, when the children see a camera or camera begin to shed tears, run or turn away, there are also opposite situations when the kids begin to "work on the camera", that is, they behave unusually, unnaturally or horosfully, that as a result interferes with good shooting. Due to the video equipment, you can shoot home movies with your child in the main role thanks to the "hidden video camera". In order for the vision monitor to become wider, in some models it is possible to connect one or three additional video cameras, the same as the one that comes with the kit. So you can conduct video surveillance in the auto-scan mode. This means that automatically on the screen will appear in sequence to appear images from each camera with an interval of five seconds. Especially useful is the function when the child begins to crawl or walk around the room.
Power sources
Both the children's unit and the parent can work and autonomously - from batteries and batteries, and from the 220V network. You yourself can choose the power source depending on the situation, however, remember that the batteries for a long time are not enough. In the baby monitors, the indicators are built in both units, which always tell you that it's time to recharge the device. If you want to save energy, you can turn off the monitor display. In this mode, the baby monitor turns into a baby monitor - you can hear only the sounds. But know that it is more convenient when the screen is turned on and the voice activation function is authorized. In this case, if the baby is sleeping in the room, the camera does not show the image, but the baby monitor is in the waiting mode. When there is at least the slightest sound in the children's room, the camera will immediately start broadcasting the image.
By the way, if you want, you can turn off the sound and leave only the image to work. Advantage of the baby monitor in the built-in digital clock with an alarm clock, as well as a night light that gives scattered soft light.
How to install video surveillance?
Due to the fact that the baby monitor works in the wireless mode, no special knowledge, tools and skills are needed to install it. According to the instructions, it is necessary to set up a camera and a video monitor on a specific frequency channel. To configure the nanny without interference, it has at least 2 and a maximum of 4 channels. In addition, you can adjust the contrast, brightness, color and sound level in settings. You must also put the camera so that she can see your baby. The best distance from the camera to the child is 1-2 meters. You can install the camera natumbochku or changing table, if there is no such possibility, you can fix it on the wall or ceiling. The chamber has a flexible panoramic holder, with which the camera can be turned in any direction. To prevent the image from being exposed, do not point the camera toward the light source. Also, place the camera away from metal surfaces, this may damage the connections.
In addition, take care of the baby monitor from blows and falls, otherwise the baby monitor may break down or lose its work.
Cost of a child's eyes
On average, high quality baby monitors cost from 7000 to 12,000 rubles. Usual black and white baby monitor can be purchased for 5000 rubles, but additional cameras will cost you 3000-3500 rubles.
Almost all parents think that the video and baby monitor are needed only in a big house or in the country. Of course, when the baby quietly sleeps on the second floor, the mother can take care of the beds in the garden, while watching the baby. But in an ordinary city apartment electronic nanny does not mix. For example, if a child sleeps in the room with a closed door or on the balcony, while you are busy in the kitchen at this time, rattling the dishes, the water is noisy, the extractor hood, washing machine or blender is working ... Or in the bathroom, the hair dryer and water are running ... And maybe you are in the next room vacuuming the carpet, typing on the printer, listening to music or watching TV ... Sometimes because of noise it's impossible to hear that the baby is already awake and crying, but the electronic nurse will tell you even the smallest sounds and movements of your baby. He will not even have time to cry, as you will be near his crib.
