Intelligent door intercoms provide convenience and security. Especially with the extension of a modern voice system by an additional video door intercom, residents can be quite sure who is actually standing in front of the door. To ensure good audio and image quality of the video door intercom system, prospective buyers should seek advice from a specialist. This is because the quality differences in modern and networked video intercom systems are large, for example, in the area of data transmission and system stability.
Most door communication systems consist of one permanently installed indoor and outdoor station each, which are connected with a cable. Modern, high-quality devices can be embedded in the system via the Internet and conveniently accessed and controlled from different locations using a smartphone, tablet or PC. The only requirement for a wireless variant is an IP gateway. However, it should be noted that due to the intensive Internet use in the environment as well as the networking of numerous technical devices in the household via the WLAN, the security and functionality of the applications is limited.
When someone rings the front doorbell, the video camera installed at the front door is activated and transmits the image to a display in the indoor station. If no one in the house responds to the ringing, the camera usually takes one to three pictures of the front entrance so that residents can view who was visiting at a later time. Additional technical functions, such as a colored signal transmission when the doorbell rings, can be programmed as desired.
