GATE AUTOMATION : ACCESS CONTROLS
APPLICATIONS
Proximity cards transmit their information to the card reader without any physical contact. This provides an easy to use vandal resistant system. Access is granted when a valid card is presented to the card reader.
ADVANCED FEATURES
Because physical contact is not required, proximity cards can transmit their data through common building materials like: concrete, brick, stone, drywall, plaster, glass, wood, plastic...in fact, through anything but metal.
Proximity card readers are maintenance free. There are no parts to wear out or adjust. Passive card technology provides and unlimited number of "card reads" and their is no battery to wear out. Active cards provide a much longer read range, but use a battery that will wear out in time (2-years) and require replacement of the card. Passive cards, unless they are physically abused, will last virtually forever.
SPECIFICATIONS
Passive card systems are available with read ranges from 3-inches up to 28-inches. Active card systems can provide read ranges up to 9-feet.
Proximity readers are not designed for stand-alone operation and must be connected to an access controller. |
