Access Control Systems

Keypad entry systems

Keypad entry systems are security access systems where users enter a PIN (Personal Identification Number) or code on a numeric or alphanumeric keypad to gain access to a door, device, or system. They're common in residential, commercial, and industrial environments.

How They Work

1. User enters a code.
2. System verifies the code against stored credentials.
3. If valid, it triggers an action:

• Unlocks a door
• Logs an entry
• Activates a device
