KR503H is an outdoor IP67-rated tamper-resistant multi-technology proximity card reader capable of reading HID,
ZKAccess and Pyramid 125 kHz 26-bit proximity cards.
Due to its standard single gang size, the KR503H is the ideal card access solution for any metal doors,
parking gates, fences, turnstiles or any security device having a single gang mounting surface.
For the highest level of security KR503H has a built-in Wiegand-Out port which can be connected to most
any access control panel (including ZKAccess C3 and InBio door controllers).
