Overview Sophisticated Design: A fully flat thin monitor with touch sensor keys. The doorphone has a gently curved, metallic-looking design that matches the home exterior. Also, the doorphone can be embedded in a wall by using the optional mount box. Wireless Monitor: The wireless monitor can be used to check visitors and respond promptly from the living room, kitchen and elsewhere in the home. As long as there are no obstacles, the maximum wireless range is approximately 100 m. Up to 2 DECT repeaters can be added to extend the range. Highly Expandable: Connect up to 6 additional monitors to the main monitor using a combination of 7-inch wired monitors (up to 3) and 2.2-inch wireless monitors (up to 6). PBX connectivity is also supported. Easy-to-use: The 1.3-megapixel image sensor on the doorphone takes visitor images at HD image resolution. Easy operation using the e-lock release button on the front and a volume control button on the side of the main/extension monitor. One Touch Voice Change: This unique safety feature makes the voice heard at the doorphone sound deeper so that a female voice sounds like a male voice. The voice change function can be activated with one touch during an incoming call using the main/extension monitor. Electric Lock Release Support for Gate: The gate or door lock can be easily and quickly released using the monitors during an incoming call, or while talking or monitoring. Picture Recording: The main/extension monitor can record up to 50 still images from doorphone calls or monitoring sessions. Recorded images on the main monitor can also be played from the wireless monitor. (Up to 50 session (up to 4 still images per session)) Night Vision: The doorphone is equipped with LED lights that enables the colour display of visitors at a distance of about 50 cm even when it is dark.
