Wireless video door intercom system for a two-family house, consisting of a door intercom with 2 call buttons with nameplates and protective cover and 2 indoor stations with 7 inch LCD flat screen (visible screen diagonal 17.6cm), each with hands-free facility. The door intercom (IP55) made of robust ABS with color camera (96° horizontal / 53° vertical detection angle) and illumination by white LEDs (for night vision up to 0.8m) can be operated with 2 C batteries (MN1400) or via 12V DC, min. 300mA (batteries and power supply not included). With 12V DC supply, the bell button is illuminated. The indoor stations with touch buttons can be set up or hung up and are powered by the included 12V power supplies. The use of an optionally available 3.7V / 2.4Ah lithium battery makes the indoor station portable. The 2.4GHz digital radio transmission ensures interference-free images and security against eavesdropping. When the doorbell rings, one of three selectable melodies sounds on the indoor station (ringing duration and volume selectable) and the camera image appears. The voice connection is established by pressing the talk button. Indoor stations with integrated ring buffer for 75 images, which can be recorded automatically when the doorbell rings or manually with time and date display. When using a microSDHC card (max. 32GB, Class 4 / Class 10, not included), video sequences can be recorded automatically after the doorbell rings. The camera image can be accessed from the indoor stations at any time. Connections on the door intercom for an electric door opener (changeover relay max. 1A at up to 15V AC/DC), which is activated via the indoor stations, as well as for a wired gong or other signal generator (normally open contact max. 1A at up to 15V AC/DC), which are activated when the upper call button rings.
