water tank with a pump inside and water nozzle. The nozzle position is fixed on the camera base. When the
window needs to be cleaned, run No. 90 Preset (or open AUX. 2 switch). The PTZ will go to special position for
nozzle and water will spray out on the window for 2 seconds. The wiper will work at this time. When the cleaning
process finishes, the PTZ will go back to the original position. Pay attention special spray liquid is required to
avoid freezing in low temperature.

5. FLAMEPROOF STRUCTURE
„ Completely consider the explosive air getting into ex-proof structure, which may lead to explosion
because of some reason and to confirm and ensure camera explosion proof performance based on its
structure gap, length and max temperature it will get to.
„ Enclosure shall burden water pressure testing for 1.5Mpa for 10~12 seconds without leakage as pass,
which is ordered in GB3836.2-2000.
„ Camera surface temperature max shall not over 80℃while it is working.
„ Window glass adopts steel glass to burden Impact and Heat change testing.
„ Enclosure protection to IP66
„ Cable for Camera uses inlaid device to tighten its screw and nut and make cable tight and no move.
