1.1.2 Example
The Smith family consists of a husband and wife, John and Suzanne Smith, and their
15-year-old daughter, Anna. The three of them live in a single-family home. The door to their
house is secured with a T25 IP Video Door Station with a KeypadRFID and a MX-DoorMaster.
One Grandstream video phone located on the first floor and another Grandstream video
phone located on the second floor near the parents’ bedroom serve as the remote stations
for the system. Anna lives on the third floor and has her own Grandstream video phone.
In addition to using the red admin card, Mr. Smith has registered a blue user card to
enable keyless access for himself, his wife and his daughter. Admin and user cards can
be registered during initial setup. This can be done simply by holding the cards up to the
KeypadRFID or the BellRFID. Once the system is operational, the user can also enter an
access PIN (KeypadRFID only). This way, in an emergency in which the user has misplaced
or forgotten his or her key or transponder, he or she can still enter the house without
having to call a locksmith.
When a visitor rings the doorbell at the door station, all three video phones ring and display
visual signals. In addition, the MX-DoorMaster, which is mounted in the entry area near
the door, plays a bell sound that has been selected by the user. Thirty seconds after the
visitor rings the doorbell for the first time, the system instructs the visitor to leave a message
(voice mailbox function). In addition, the visitor can choose to leave a message without
ringing the doorbell by pressing the letter button. Anna sometimes uses this function to
quickly let her parents know when she is on her way to a friend’s house. In summary, the
following functions are available:
Open Door/Keyless Access
• With one of the user cards (or with the admin card as well)
• With the access PIN (KeypadRFID only)
Ringing the Doorbell for the Family
• By pressing the white bell button of the camera module
• By pressing the blue bell button of the KeypadRFID or BellRFID module
• By pressing the corresponding bell button of the BellRFID
Leaving a Voice Mailbox Message
• By pressing and holding the blue letter button of the KeypadRFID/BellRFID module
• After ringing the doorbell or directly, without ringing the doorbell
Listening to Voice Mailbox Messages
• On the KeypadRFID/BellRFID module (only in connection with a user or admin card, if
function has been activated)
• On the Grandstream video phone or a dierent remote station (can be accessed by
everyone in the house)
