The transmitter behaves like a typical remote monitoring receiver, which directly receives and manages the Contact ID communication of the alarm center.
Contact-ID matches the corresponding messages to the reports and then forwards them to the users' phones in the form of a "push notification",
for all users at the same time. The text of the notifications can be individually adjusted and tailored to the customer's needs.
The connection between the unit and the app is checked every 30 seconds.
In case of a connection error, the server will notify the application to its users in a separate message.
This avoids the weakness of classic GSM communicators (with calls and SMS), such as expired SIM and blocked GSM communication detected late.
or inoperability due to a defective device.
