Okay, so I finally upgraded my janky old access control system with this MENGQI 4-door panel, and wow – the price-to-performance ratio is insane compared to those "professional" quotes I got.

First off, installation was smoother than expected. The TCP/IP setup saved me from running new wires everywhere. Pro tip: If you're tech-savvy enough to configure a router, you can handle this. Though fair warning – their PDF manuals read like they were translated through Google Translate... twice.

The real MVP here? The support team. I emailed them at 2AM about a Wiegand reader compatibility issue (expecting a reply in days) and got a solution with screenshots by breakfast. That alone justifies the cost.

Some quirks though: The management software feels like it’s from 2005 – unlocking hidden features requires random keyboard combos like cheat codes in a PlayStation game. And mobile app? Forget about using it unless you want to rebuild your entire office network topology.

But for $200-ish? Controls four doors flawlessly, handles 20K users, and the auto-schedule feature means I never have to manually unlock the lobby at 8AM again. Just buy the enclosure/power supply bundle unless you enjoy cabinet Tetris with existing wiring.
