Researchers at FORBIX OÜ developed and very efficient method of wireless long distance remote control for SOS signal transfer. The solution comprises of a transmitter and a receiver unit. The way these wireless devices work, is by emitting an electromagnetic radio frequency wave. Signals carry from the remote controller to the receiver.
The remote controller comprises of the long range transmitter. It works on a rechargeable battery for its operation. The receiver is inside IP65 ABS plastic enclosure. To able to sustain outdoor weather conditions, we have a metallic enclosure around it.
