Requires higher cabling costs with (minimum of 12 cables) to support doors, hardware, data connections, power, etc.
Control panels support limited doors - after that limit is reached additional panels are required.
No hardware failover protection - when a panel goes down, all doors connected to the panel are affected.
System relies on battery backup for power failure - no monitoring or alerts for low battery.
Managing permissions, schedules and other administrative tasks are time consuming and complex.
Difficult to troubleshoot - more equipment, longer wire runs, and limited tools.
Controller installs at the door - reducing cabling costs (number and length of cables).
Highly scalable - simply install a new door controller and connect to the nearest network switch.
Hardware failover protection - controller failure only affects one door.
Back-up power provided by UPS at the PoE switch. System features health monitoring and alerts.
Central management of credentials and administrative maintenance via Internet or smartphone.
Easy to troubleshoot - less equipment, shorter cable runs, system/network monitoring tools.
