The intercom is a very important technical device for the home. It allows guests to contact the owners of the house. Previously, the intercom was used exclusively for audio communication, but today the functionality has been expanded and video intercoms with recording function have appeared. Such an intercom will not only help to contact the guest, but also provide protection against thieves and ill-wishers.
If you are looking for a new intercom, experts https://hikvision.co.ua/domofony/zapis_video/ will help to understand how to choose the right ego.
What does an intercom with the possibility of video imaging and recording consist of?
The intercom is a multifunctional system that consists of several mandatory elements:
- Call panel;
- Internal monitor;
- Cables;
- Power unit.
Such an intercom is not only a means of communication, but also reliable home protection.
The call panel is a unique button for connecting visitors with the owner of the house. The panel itself is located outside the apartment or house. The main functional elements of the panel are the call button, separate camera capability, microphone and speaker, display, case. The body of the panel must be strong and resistant to adverse environmental factors, since it is often placed outdoors.
An internal monitor is a control center that is located in the apartment itself or in the house. It is a display on which all information is displayed. When choosing an internal monitor, pay attention to the quality of the image and the resolution of the screen. Also, pay attention to the quality of the speakers. Sound is just as important as picture.
The power supply can be 12-volt or 24-volt. Check these characteristics at the purchase stage and choose the device that suits you.
What kind of intercoms are there?
Intercoms are:
- Analog;
- Digital.
Analog is cheaper, however, the quality of the picture is significantly inferior compared to digital. However, some models of modern analog intercoms are already of better quality and allow the connection of several panels and video cameras. For a simple user, this is enough.
If a more professional system is needed, then preference should be given to digital systems. Here on the screen you can see more than four cameras, in addition, it connects to more than 20 devices.
It makes no sense to buy a digital intercom for an apartment if a multi-apartment analog intercom is installed in the house. It is practically impossible to connect a digital one to an analog multi-apartment system.
What should you pay attention to when choosing an intercom?
When choosing an intercom with a recording function, it is important to pay attention to:
- Screen size;
- Memory volume;
- Anti-vandal protection.
In total, there are two options for recording information with an intercom — photo registration, video registration. Accordingly, in order for the intercom to save information, it must have built-in or external memory. Therefore, first of all, pay attention to the amount of memory. Choose intercoms that support an SD memory card.
The bigger the screen, the better, since it depends on how easy it will be to recognize the visitor. Do not use excessively large screens with low-resolution panels. The picture will be blurry, but on the contrary, it will be better on a small screen.
Anti-vandal protection will help protect the system from thieves and intruders. This is especially true for disadvantaged areas.
