First impressions matter, and unboxing this 4-door controller felt promising. The industrial-grade components and screw terminal blocks screamed durability - no flimsy connectors here. I could tell this was built for serious access control setups.

Setting up the TCP/IP connection was smooth sailing. The fast signal transmission lived up to its claims when I connected it to our network switch. The 100m reader distance support meant I could place card readers far from the controller without signal degradation.

However, the software installation on Windows 10 was a nightmare. The 'PLEASE UPGRADE DRIVER' error completely halted operations. After hours of troubleshooting, I discovered the manufacturer's website had outdated drivers. Once I found the correct driver through community forums (not ideal), the system worked flawlessly.

The 40,000 card capacity and 100,000 offline records are impressive for the price point. I tested it with our WG234 readers and various 125KHz/13.56MHz cards - all worked perfectly. The ability to control 4 doors independently (card-in/button-out) makes this ideal for medium-sized facilities.

Final verdict? Hardware gets 5 stars, but be prepared for software headaches. If you're comfortable with technical troubleshooting, this offers incredible value. For plug-and-play solutions, look elsewhere.
