Product Description

GD-K4 Granding Two Doors Access Control Board with Power Box




GD-K4 access control panel is built on flexible, open technology to provide management, real-time monitoring, and control of your access control system-all from a browser, with no additional software to install. Our secure Web-hosted infrastructure and centralized online administration reduce your IT costs and allow you to easily manage all of your access points in a single location. GD-K2's versatile design features take care of present and future needs with ease and efficiency. It is one of the most rugged and reliable controllers on the market, with a multitude of bulit-in features. The GD-K2 can communicate at 38.4 Kbps via RS-485 configuration or Ethernet TCP/IP networks. It can store up to 30,000 cardholders. SDK(software development kit) is available for the customer to integrate the controller into existing access control software or to develop new software. 

Feature:

1. There are over-current protection, over-voltage protection, reversal protection for the power supply and all the input and output terminal. 
2. Multiple hardware protection meansure.
3. It can be integrate with other security systems such as CCTV, fire alarm, BAS(building automation system) and other systems to configure total security system. 
4. The controller support different wiegand format, and can connect to different reader, including ID card reader and Mifare card reader. 
5. Connect with variety of sensors, alarms, exit buttons, electric lock and other devices. 
6. Using either serial or TCP/IP communication, it provides reliable network system.
7. It is easy to manege the system by browser from client PC. There is no need to install software on each client. 
8. Normal open after first punch card can be setup.
9. Real-time Monitoring of Door Status.
10. Using the management software, it allows real-time monitoring and control of door opening and closing of the whole system.
