school bus rear vision camera car reversing camera with 130 degree free view angle
IP 67 water pressure
P=ρgh ,Water depth: about 60cm,(Equivalent to IP67 water pressure) P=1000kg/m3*10g*0.6m
P=6KPa,So IP67's pressure is less than 100KPa, It doesn’t meed high pressure waterproof
test’s standard.
IP 69K water pressure
P=ρgh,waterproof test pressure:100KPa,(Equivalent to IP69 water pressure)
100000=1000kg/m3*10g*H,H=100000/1000/10=10m
