What should be noted when installing the radio frequency access control card reader?
On market at present, the main frequency of 125 KHZ, several frequency of 13.5 MHz and 2.45 GHz radio frequency (rf) access control card reader, and two frequency of 125 KHZ and 13.5 MHz radio frequency card reader in the majority (125 KHZ is generally EM format ID card, 13.5 MHz is MF1 format commonly IC card), the two kinds of card reader, are basically the same on applied technology, installation requirements are essentially the same.
When you install the radio frequency card reader, you should pay attention to the radio frequency interference and metal shielding.
1. Radio frequency interference: the installation distance of two card readers should be avoided at the time of installation of radio frequency access card reader.
Special tip - when installing a card reader, try not to have a partition.
2. Other interference: when installing the radio frequency access card reader, you should select a device that does not have the same frequency, and avoid the motor, welder and other appliances to avoid interference.
3. Metal shielding: because the radio frequency technology for metal mask, rf entrance guard card reader is installed, try not to install in the metal surface, because close to the metal leads to read distance shorter or cannot read card, if the installation on the metal, suggest install the card reader in the metal first invisible, install again.
4. Communication distance: the card reader on market most commonly used WEIGAND communication mode, this kind of card reader communication distance in 100 meters or so commonly, recommendation 80 meters, the installation distance is too long can lead to can't normal delivery card number information, lead to read ,card error, or unable to transfer.
