gemino expandable and gemino4 (4 programmable inputs)
Universal GSM/GPRS Communicators
gemino is a Bi-directional Universal GSM/GPRS COMMUNICATOR specifically developed for Professional Security applications, even though its flexibility enables its use in many telecom/communication, industrial and residential applications, basically anywhere there is a need to transmit signals in a reliable manner and in absence of the fixed line (or as alternative to it) in order to protect sensitive installations (like as, but not limited to, industrial plants, solar installations, rural and marine installations, incubators, glasshouses, etc.).
As an interface, gemino steadily controls the status of the PSTN line: in case of its absence, all linked communication devices will use the simulated phone line delivered by the communicator, therefore allowing to make and receive calls via GSM with a very high-quality audio output thanks to the adoption of a digital audio channel.
With gemino4 and gemino expandable versions it is also possible to send signals through the contact-ID protocol via GSM net, i.e. to Central Monitoring Stations. Contrary to many other devices currently available in the marketplace, gemino integrates the GSM antenna directly on the PCB, making the external antenna basically redundant for the majority of the application while, for particular installations an external antenna can be added and the Communicator can always manage and provide the best quality signal between the two; moreover, other interesting news is that gemino offers the possibility to manage 2 different SIM cards, even from 2 different providers, monitoring continuously the status of the GSM network according to three different simultaneous modes:
- measuring the signal level and quality
- verifying the proper registration to the GSM network
- detecting the presence of interferences (jamming)
