AutoFon «Alfa-Mayak» 5
The «AutoFon Alfa-Mayak» device consists of a GSM/
GPRS modem, a GLONASS/GPS receiver, a programmable
microprocessor and an autonomous power supply.
The autonomy and miniature dimensions of «AutoFon Alfa-
Mayak» allow the owner to discreetly install it in the most
difficult-to-find place. Since the device is in sleep mode most of
the time, it is extremely difficult to determine its location with
air scanners and GSM signal detectors. If a system of jamming or
suppression of GSM frequencies is used by attackers, the long-
term autonomy of «AutoFon Alfa-Mayak» will allow waiting for
the suppression means to be disabled and contact the owner.
The operating mode «AutoFon Alfa-Mayak» is set by the owner
from your personal account on the server: control.autofon.ru,
or via the Autofon KSA mobile application for Android and
iOS. Direct control via SMS is also possible. « AutoFon
Alfa-Mayak» determines its coordinates using the satellites
of the GLONASS/GPS navigation systems and can transmit
them in “packets” via GPRS to the monitoring server. Along
with location coordinates, all device settings and status are
transmitted.
«AutoFon Alfa-Mayak» can operate in two main modes.
Continuous “ACTIVE” and interval “SLEEP”. In continuous mode,
the device is constantly in touch and is ready to receive a
command from the owner at any time. The maximum operating
time in continuous mode is 6 days, in the “SLEEP” mode up to
3 years.
In the interval mode “Sleep” the device is in a “sleep” state and
accepts commands only at the moment of activity, which comes
at the time programmed in the alarms.
«AutoFon Alfa-Mayak» has two alarms T1 and T2 wakes up at a
specified time interval to perform the following actions:
- determination of the exact GLONASS/GPS coordinates
- determination of approximate LBS coordinates by base stations
of a cellular operator (most energy-efficient mode) with accuracy
from hundreds of meters to several kilometers. This mode is
configured by default.
