Audio Alarm Verification
Each control center includes a speaker and a microphone. In case of an alarm, the
panel transmits the message to a monitoring center. The operator can then
immediately initiate a phone connection to your customer's panel and listen into his
premises, so the situation can be verified, e.g. corroborate an intrusion attempt or a
false alarm caused by the user. A communication between the person in the
premises and the monitoring station can be established and helps to reduce
unnecessary costs due to (e.g.) police interventions.
Example:
1
Panel transmits the initiated alarm to the receiving station.
2
Monitoring center personnel listens into the premises and distinguishes between
an alarm and a false alarm.
3
The personnel can speak to the premises and the other way around. In case
of an accidental alarm, customers provide previously defined codes to identify
themselves as authorized users.
The customers are also able to listen into their premises whenever they like via a
telephone call (e.g. as baby phone function).
