Flats and apartments are vulnerable because they have a shared entrance. Hikvision has various solutions for these residential objects, so that the entrance is difficult to enter for unwanted visitors. The intercom systems have a speaking-listening connection and a video connection. In the apartments, the entrance door can be opened remotely by means of the internal station or via the Hikvision Connect App. The IP system offers the best technology, easy to install and configure per user. RFID also has access to the many possibilities. Connecting external equipment such as IP cameras is also possible.
