The
Wireless Transceiver system 2.1 is designed to be used for security surveillance
in industrial environment where it is either not possible or practical
to lay cables to transmit video and audio signals. These modules are housed
in industrial grade IP 65 enclosure with high quality bullet cable glands
installed at the various cable inlet and outlet to ensure that these units
are waterproof and air-tight. Proper enclosure will prevent water, dust
and chemical vapor from entering the housing and corrode the components.
These units come with an industrial grade 35W, 12VDC single output switch-mode
power supply with voltage stabilizer housed within the IP 65 enclosure.
Field application
These systems are used in the
transmission of video and audio signals from video surveillance cameras
in outdoor installations in petrol-chemical complexes, military training
complexes, mining installations and industrial installations where laying
of cables are not practical or feasible. It can also be used by schools,
warehouses or plants which needs to set up temporary surveillance facilities
to monitor certain activities or processes.
