6. Protection (IP67, wide voltage)
IP67: The camera passes a series of strict test on dust and soak. It has
dust-proof function, and the enclosure can works normal after soaking
in 1 m deep water for 30 minutes.
Wide voltage: The camera allows ±30% (for some power supplies)
input voltage tolerance (wide voltage range), and it is widely applied to
outdoor environment with instable voltage.
