OPU-2 A is a robust, surface-mounted enclosure, made of white
ABS plastic. Owing to its aesthetic appearance, the enclosure can be installed
in conspicuous locations in usable space interiors. Its neutral design and
compact size make it possible to install the SATEL GSM and GPRS modules inside
the enclosure. OPU-2 A is provided with a tamper switch and can
accommodate an antenna, e.g. ANT-GSM-E, ANT-OBU-Q or ANT-900/1800.
