Ajax SpeakerPhone makes alarm verification as fast as a phone call. When an alarm goes off, the sirens are turned off and the alarm centre operator is connected with clear full-duplex communication. The operator can listen to the sound environment, talk to people on the ground and immediately decide whether to call security, police or emergency services - or whether it is a false alarm.
The device works independently via Wi-Fi + SIP or as part of an Ajax system (Hub 2 4G / Hub 2 Plus / Hub Hybrid 4G). With hub connection, the encrypted Jeweller/Wings backups, so events and voice traffic continue even during network outages.
