Two wires - Duo

The Duo System 2-polarized non-polarized digital video door entry system continues to evolve, today we are facing a truly competitive evolution: the advent of the GW2IP gateway allows enviable performance guaranteed by the top of the R&D Farfisa. In fact, the Duo network integrates with the IP by opening new frontiers without limits, first of all it is worth highlighting the possibility of video calling the external unit and remotely controlling access without limits of distance.

Relevant increase in the number of users, greater integration and ease of installation, The Duo System has further enhanced its strengths: quick and easy assembly, and competitive performance and features. DUO SYSTEM is compatible with many internal and external station lines and with door keeper exchanger, too.

Among the available accessories, the technical development of the 2231 separator has allowed a major upgrade in the number of possible users, now up to 20,000. Duo System is now also a “pure” 2-wire system, thanks to the ALBA, SOLVO and AGORÀ push-button stations. As with all the other components which use this technology, power is delivered directly over the 2-wire bus, therefore making it possible to further optimise the assembly. The ever-increasing demand for enhanced performance has been met. The new modulator allows a level of integration with Video surveillance systems which until now was unimaginable. Thanks to FTDUO, the same is true for Telephony.
