After installing this system across multiple locations, I can confidently say it gets the job done—but be ready to roll up your sleeves. The outdated Windows software feels like a time capsule (think Windows XP era), yet it’s surprisingly powerful once you dig into the optional plug-ins. Pro tip: YouTube tutorials from 'Security Camera King' saved me hours of frustration.

The real MVP? The battery backup. During a 30-hour power outage, it kept our doors secure without breaking a sweat. I also love how it handles permissions—grouping staff by department and setting time-based access (students locked out after 5 PM? Yes please). One quirk: the 'First Card Open' feature is genius for ensuring someone’s onsite before unlocking doors at 8 AM, but it stubbornly stays open until the schedule ends. I hacked around this using extra channels and a $10 timer module—geekery required.

Hardware-wise, it plays nice with RFID stickers, key fobs, and even Bosch motion sensors. But skip the included docs (they’re borderline gibberish) and head straight to GitHub’s 'uhppoted' library for clearer control options. Annoyances? The Ethernet setup is stone-age—no DHCP or web interface—and door lock states are mysteriously absent from monitoring. Still, for the price, it’s a workhorse that won’t quit.
