Thodukonics Invented a technique for wireless communication via 100~250 volt AC electric line in 1990 and started marketing them under the brand name Powerfone.

The main advantage of this advanced intercommunication equipment, the Powerfone, is that it requires no extra wiring as it works seamlessly through the electric power supply wire.

It will be working in any country where the AC supply voltage is between 90V and 250V. And thus saves a lot of wiring and is completely robust and stable.

Now we have expanded our product line by introducing the 900Mhz and 2.4Ghz fully Digital 1000 user wireless Intercoms.
We have following models suiting different user applications and uses.

Our Power Line Intercom

Thodukonics invented a new technique for wireless communication via 100~250 volt AC electric lines in 1990 and started marketing it under the brand name Powerfone. The main advantage of this advanced intercommunication equipment, the Powerfone, is that it requires no extra wiring as it can work through the existing electric power supply wires. It functions in any country with an AC voltage between 90V and 250V. You can get the best performance and long range when the Powerfones are connected to the same power distribution transformer and same phase lines.

Additionally, you can plug our intercom into a DUAL Phase 220V AC outlet to avoid phase issues (110V region). In comparison, normal telephones work via telephone lines (wire), whereas our intercom works via 110V or 230V electric supply lines, eliminating the need for additional wiring. The use of high-quality components, precisely tuned electronic oscillator circuits, and advanced FM technology in our systems enables you to achieve digital clarity and long range, far superior to similar products available in the global market.

Strict quality control in the manufacturing process ensures the durability and best operational performance of these products. In fact, there are no equivalent products in the market for some of our models. Installation of the system is very simple: just plug the intercom into a 100~240V AC outlet in the required locations, and the system is ready for communication. You can easily relocate the system whenever and wherever you need it.

You can also plug our intercom into a "DUAL Phase" 220V AC outlet to avoid phase issues. Available models include: Long range hotline wireless home intercom systems, cordless telephone call-transferring intercoms, wireless multi-channel intercom systems supporting up to 1000 stations, and wireless multi-line EPAX. If you are not connected to the same transformer, we also offer single-core wire wired intercom systems.

Our latest 900MHz or 2.4GHz wireless intercom systems do not require power lines for communication. For more details, click on the specific models. FM wireless intercoms are also known as Mains power intercom, Mesh Talk intercom, Door Entry intercom, household power intercom, household electricity circuit intercom, domestic power intercom, wall power intercom, line power intercom, AC power plug-in intercom, hotline wireless interphone, grid power intercom, wireless security intercom, plug-and-play intercom, car intercom system, apartment doorbell, and vehicle intercom system.

Note: You get the best performance and long range when Powerfones are connected on the same power distribution transformer and phase lines.
