What is a
2-wire video Intercom systems are IP based, but signals are carried on two wires rather than the CAT5/6 cabling required for a digital IP Intercom.
With only one pair of wires required, 2-wire Intercoms are excellent for updating systems where new cabling is not an option.
2-wire intercoms are half-duplex only. With only one pair of wires, they have to be used for both transmit and receive. When one party is talking, the wires are being used to send the voice to the other party. Then the wires are used to receive the voice from the other party and vice-versa.
This setup makes things simple when you are upgrading an old intercom system. With fewer wires required, you can reuse the existing ones from the previous hardware. Installation becomes easy, fast, and cost-effective. With advanced IP signalling conversion (IPG) technology, VTEK 2Easy 2- wire systems guarantee better video quality when compared to traditional analogue systems.
