Nexus communicators are available in different models for 2G, 3G and 4G/LTE mobile network connectivity. The name of the model identifies its specific features. Nexus/3G operates on 3G networks and when unavailable it executes fallback to 2G networks; Nexus/4G operates on 4G/LTE networks and when unavailable it executes fallback to 2G networks. Completely integrated into the control panels via the BUS, these devices offer excellent performance. The Nexus manages all types of calls (voice, SMS, DTMF and SIA-IP surveillance protocol communications) and allows the execution of commands sent to the control panel via SMS or from recognized numbers. The Nexus/G, Nexus/3G and Nexus/4G models also provide the necessary communication channels to the INIM Cloud thus allowing the user to manage their system through the InimHome App, send commands and receive push notifications and, similarly, allowing the installer to manage it via the InimTech Security App and the Prime/STUDIO programming software. Nexus can operate both as a main device for event notification and a backup device in the event of PSTN line down or ADSL connection failure.
It is always advisable to check the costs, coverage and services of the various mobile operators in order to find out which is the most suitable.
Meets grade ATS-6 of the EN50136 standard for alarm/event transmission systems.
Nexus devices are not the usual devices for connecting to cellular networks. They offer excellent performance, integrating with the INIM burglar alarm systems. The installation is simple: they must be connected to the BUS like any other device and can be installed either on the central or in any position reached by the BUS so as to increase the reception quality of the field. Once connected to the control panel, they provide an additional communication channel in addition to the PSTN, a channel from which it is possible to send voice or digital calls over the GSM / 3G network.
The control panels therefore have this second telephone number available, which in addition to answering incoming calls by making the voice menu available with DTMF commands to the enabled users. With Nexus, the control panels send automatic or customizable SMS messages for each event, and the control panels can also receive commands sent via SMS. So you can enable or disable scenarios and outputs, request the status of the device and much more. The same operations are also possible with the recognition of a given caller number (CallerID).
Nexus / G and Nexus / 3G go even further. In addition to all the functions listed above, they allow the management of the stations via the GSM / GPRS / 3G network. The device connects to the IP address programmed in the control panel during installation, or to another IP address that the installer can decide from time to time and set by sending a simple SMS. Shortly after receiving the SMS, the PC connects to the remote post office using the specified IP address. Thus it is possible to activate a remote control session via GPRS / 3G to read / write the control panel programming, even away from the office or with a mobile connection such as "Internet-key", tethering or smartphone hotspots.
Nexus / G and Nexus / 3G make a digital communicator available to the control units to the surveillance stations with the SIA-IP protocol. Nexus / G and Nexus / 3G allow both the installer and the user to access the Inim Cloud or peer-peer services and can be used either as the main device for connecting to the Cloud or as a backup device. lose the connection through the wired LAN channel. A service-enabled SIM card is required to connect to GPRS / 3G networks. It is advisable to analyze the tariff profiles of the various operators to identify the most suitable.
Nexus / G and Nexus / 3G also handle special characters or foreign alphabets. Nexus / 3G is the evolution towards new communication networks in 3G technology.
Nexus, Nexus / G and NEXUS 3G have led status indicators and a practical magnetic antenna with 3 meters of cable.
