Door Buzzer Systems
A door buzzer system is a primary access control solution where a buzzer sounds to notify the person inside that someone is at the door.
The door can then be remotely unlocked. This is ideal for small businesses or apartment buildings where direct communication with visitors is not necessary.
Example: A door buzzer in a small retail store in Brooklyn allows employees to quickly grant customers entry without leaving their station.
Intercom Systems
An intercom system offers more advanced functionality by allowing voice (and sometimes video) communication between the person inside and the visitor outside.
These systems enhance security as the user can verify who is at the door before granting access. Intercom systems are widely used in more significant residential buildings and office complexes.
Example: In a commercial building in Manhattan, an IP-based intercom system enables the receptionist to see and speak with visitors before remotely unlocking the entrance, ensuring only authorized individuals gain access.
Which One Should You Choose?
- For Small Businesses or Apartments: A door buzzer might be sufficient if there’s no need for real-time communication.
- For Larger Buildings or Businesses: An intercom system adds a layer of security by providing audio and video verification before allowing entry.
