Let's dive into this 4-door access control system that promises security and convenience. I've been using it for a few weeks now, and here's what I found.

The installation was surprisingly straightforward. The detailed video guide and wiring diagram made it a DIY-friendly project, even for someone with basic technical skills. Like other reviewers mentioned, you'll need to purchase an access control cable separately - don't forget this!

The hardware quality is impressive. The electric strike lock has a massive 2204lbs holding force, giving me peace of mind about security. I particularly appreciate the multiple access options: RFID cards, PIN codes, or even card+PIN combinations for higher security areas.

The remote access via smartphone app works reliably (both iOS and Android), though as one reviewer noted, this does require internet connection. For local operation though, internet isn't necessary once everything is set up.

Now for the not-so-great part: the software experience is mixed. While functional for basic operations like managing users and generating reports, the interface feels outdated and some security warnings about the backup files are concerning. Tech support is responsive (even at odd hours!), but the software aspect could definitely use improvement.

Storage capacity is generous - up to 20,000 users and 100,000 logs should be more than enough for most applications. The scheduling features work well for automating door access at specific times.

Overall, this system delivers where it counts - reliable hardware performance and flexible access control options. Just be prepared for some software quirks and make sure you're comfortable with basic networking setup.
