Standalone Acess Control system
The Proximity Controller is a solid state of device based on SMT technology for high performance & excellent features to control 1 - 4 doors with in & out reader, cards & events. The proximity technology reader constantly transmits a low-level fixed RF signal that provides energy to the card.
When the card is held at a certain distance from the reader, the RF signal is absorbed by a small coil inside the card and powers up the card’s microchip, which contains a unique identification code. Once powered, the card transmits the code to the reader. The whole process is completed in microseconds.
