SpeakerPhone Jeweller is a voice module designed for quick audio alarm verification via direct voice calls between a monitoring company and a secured site. The device provides clear and secure full duplex voice communication using the VoRF1 proprietary audio streaming protocol and AI technologies. In case of an alarm, a central monitoring station (CMS) operator can immediately contact the facility to speak with someone on the spot or listen to what is happening. The operator assesses the situation and takes the right action — and only when the threat is real. Also, operators can use SpeakerPhone Jeweller to deter intruders or respond to auxiliary alarms.—Communication VoRF communication technology Proprietary wireless audio streaming protocol using time division duplex.Key features:Two-way communication.Advanced sabotage protection.Full duplex audio communication.Radio communication rangeup to 1,700 mBetween the device and a hub in an open space.Frequency band : 863.0–865.0 MHz Jeweller communication technology Proprietary wireless communication technology to transmit commands, alarms, and events.Key features:Two-way communication.Advanced sabotage protection.Block encryption featuring a dynamic key.Instant notifications.Remote control and configuration in Ajax apps.Frequency bands : 866.0–866.5 MHz / 868.0–868.6 MHz / 868.7–869.2 MHzMaximum effective radiated power (ERP) : up to 25 mWAutomatic power control to reduce power consumption and radio interference.Radio signal modulation : GFSKRadio communication range : up to 1,700 m Between the device and a hub in an open space.AI-powered sound optimization It provides:Clear voice transmission.Suppression of extraneous noise.Improved audibility even at long distances.Option to set up the AI feature in Ajax apps.Voice audibility : up to 10 mAuto adjustment of the microphone sensitivity.Output speaker power : 3 WSpeaker volume : up to 103 dB / 83 dB at a distance of 1 m.Frequency range : from 200 Hz to 16 kHzAudio codec : OpusRemote firmware updateWhen a new firmware is available, an admin or PRO with the rights to configure the system can run the update in Ajax apps.The hub must be connected to Ajax Cloud via Ethernet or Wi-Fi.
