Frequently Asked Questions
Q: What type of RFID cards does the SCR100 access control system support?
A: The SCR100 includes a built-in 125kHz EM module and natively supports EM proximity cards. It also has an optional upgrade path to support 13.56MHz Mifare smart cards, making it flexible for a variety of card-based access control environments.
Q: Can the SCR100 RFID controller work without a PC or network connection?
A: Yes. The SCR100 can operate in fully standalone mode. It stores up to 30,000 user credentials and 50,000 transaction logs onboard. Data can be downloaded and configurations uploaded via a USB flash drive (USB Host port) without any network connection required.
Q: How does the Wiegand In & Out feature work on this access controller?
A: The Wiegand In port allows you to connect an additional external card reader to the SCR100, expanding its range or coverage area. The Wiegand Out port enables the SCR100 itself to be used as an external reader connected to another access controller — ideal for multi-door or layered security configurations.
Q: Does this access control system include time attendance functionality?
A: Yes. The SCR100 supports time zone and group scheduling, making it suitable for both door access control and employee time attendance tracking. All entry and exit events are timestamped and stored in the 50,000-record log, which can be exported via USB or accessed through the embedded web server or management software over Ethernet.
