Wide-angle HQ color camera with integrated speaker module and two call buttons for the installation of audio/video systems using 2-wire technology. The color camera features a 1/3-inch sensor for an extended capture range (135° horizontal/96° vertical) and is equipped with LEDs to illuminate the recording area. There is a volume adjustment for the speaker and microphone. Management of up to 98 call buttons is possible via the code lock/keypad module or with two-row call button modules. With single-row call button modules, up to 49 call buttons can be used. The door opener (max. 30 Ohm internal resistance) is connected directly to the terminals S+ and S (18 V, 4 A surge current, 250 mA holding current). An external door opener button (e.g., post lock) can be integrated via the terminals PL. An additional power supply can be connected to terminals 1 and 2 (e.g., for large systems with multiple door stations). The device is equipped with several status LEDs that indicate the following operating states: door open, communication active, call made, and system busy. An integrated brightness sensor automatically turns on the background lighting in the dark. The device can be configured either with configurators or via PC and TiSferaDesign software. Note: When using the left call button on the speaker module or the two-row call button modules, the jumper (J1) must be removed.
