Backlighting is needed to illuminate the face of the person standing near the door. A useful function, especially if the corridor or place at the gate is poorly lit. Backlighting can be diode or infrared. Diode light can turn on automatically, remotely or by reacting to movement in the dark.

Infrared illumination works in the invisible spectrum, so those who come will not notice the glow. Such illumination is suitable if there is no desire to show that the area is guarded.U can find more in https://timebusinessnews.com/the-nuances-of-choosing-an-intercom-in... .There are many intercoms for apartment on the market.

Intercoms with a memory unit can take pictures or videos of those who are near the entrance to the house or apartment. The files will be stored in the memory of the device. They can also be transferred via Wi-Fi to your phone and computer. Some models can even be controlled via the web.

In some models, you can connect motion sensors to the panel, so that the shooting starts automatically when someone approaches the camera.

Video recordings will be stored on a memory card standard SD or microSD. Some models are equipped with their own flash memory, but its volume may not be enough, so it’s better to use an additional memory card. If there is Wi-Fi, you can connect the cloud to store records there.
