UHF ( Ultra High Frequency ) is a system used in the applications where long distance access card and sticker detection is required. UHF technology is used in the barrier automation Systems. Standalone UHF OGS is an economical system, where there is no need for extra remote control, button or a security guard to open the barrier. Standalone UHF OGS has two options as 6 and 12 meters of detecting distance. Before the cards and stickers are delivered to the users, they are registered to the uhf antenna. The sticker is sticked on the front glass in a clearly visible position. When the car approaches to the UHF antenna, it detects the sticker or the card. It communicates with the reader and sends the open commend to the barrier. If the sticker or the card is not registered to the antenna before, the barrier does not open. The cards and stickers are registered to the antenna in two different ways. In the first way, the card or sticker is brought close to the antenna. There is a red button next to the antenna ; while pressing this button, first the adding card is shown to the antenna. After that, unregistered cards are shown to the antenna one by one. Deleting a card or sticker from the system is done with the same procedure; first showing the delete card, then showing the cards to be deleted. In the second way ; if the card or sticker to be deleted is lost , or if the access right of any car is going to be cancelled, then the card can be deleted through the software. The standalone software is used only for adding or deleting the cards. The software is installed in the computer and the computer is brought close to the antenna. When the cards are added to the antenna with adding card, they will appear on the software. If the id of any card in the software is deleted, then the related card will no longer be authorized for entrance through the barrier. The package of 6 & 12 meter UHF reader includes mounting part, add and delete manager cards and UHF antenna. The antenna pole, barrier and barrier accessories are offered as an option. In case of power cut, the system can keep working in standard mode if it is connected to a UPS. Standalone UHF OGS can be used in car parks, residential buildings, private and public areas, universities, hospitals and all similar locations.
