This video intercom just replaced a simple intercom, for which we had recently ironed a new cable, we have therefore used (if a 10 m cable is supplied). For installation and the various connections outside of the element as the element inside, multilingual operating instructions as well done, DONT we had no problems. He then someone must go and ring the bell touch screen lights up and is ready to operate, and it briefly just press a button to speak (we found that he had to repeat the maneuver in the event of power failure). Someone can also watch the street without rings, in this case if we speak from inside you do not hear us out. The flat touch screen menu allows you to select the language, adjust brightness, contrast, color, and sound (for sound, it is only possible to adjust the volume of the bell that meant lon inside the volume speakers nest meanwhile not adjustable, we hear both sides very strong and very much). The image is dune average but adequate definition, the effect wide angle for easy viewing that sounds. Once night falls on the outer housing of the doorbell button panel lights blue (strong light!), The place where the register name séclaire dune white light (intense too!). We find the element outside the cap a little short to sufficiently protect the casing in the event of heavy rain, we'll make sure labriter more. Regarding the portion fingerprint scanner, we currently have nen no usefulness, we do not have yet douvre electric door system.
