Do you need more than IP66 dome cameras?
A few vendors are offering IP67 and even IP68 domes.
For example, this new Digital Watchdog dome touts it's IP68 rating, and the 'submersible' protection it carries:
Indeed, a quick check of the 'Ingress Protection Code' detailed in ANSI/IEC 60529 break the different ratings down like this:
IP66: Test duration: at least 3 minutes, Water volume: 100 litres per minute, Pressure: 100 kPa at distance of 3 m
IP67: Test duration: 30 minutes, The lowest point of enclosures with a height less than 850 mm is located 1000 mm below the surface of the water
IP68: Test duration: continuous immersion in water, Depth specified by manufacturer, generally up to 3 m
In general, 'outdoor ratings' of IP66 are common because the rating protects against the typical environment of harsh rains and wind driven dirt. Going above IP66 indicates the device can be completely under water at least for a period of time; which is not typical of or needed by surveillance gear.
Our camera finder shows 60 dome cameras claim a higher IP rating than IP66.
The question I am asking: Why? In which application are ratings higher than IP66 important for cameras?
