1.1.2 Example

The Smith family consists of a husband and wife, John and Susanne 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 T24 IP Video Door Station with a keypad and a T24-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 system startup. This can be done simply by holding the cards up

to the keypad. Once the system is operational, the user can also enter an access PIN.

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 T24-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 the three user cards (or with the admin card as well)

• Or with the access PIN

Ringing The Doorbell For The Family

• By pressing the white bell button on the camera module

• Or by pressing the blue bell button on the keypad

Leaving A Voice Mailbox Message

• By pressing and holding the blue letter button on the keypad

• After ringing the doorbell or without ringing the doorbell at all

Listening To Voice Mailbox Messages

• On the keypad (possible in connection with a user or admin card only,

function must be activated)

• On the Grandstream video phone (can be accessed by everyone in the house)
