An IP rating or code is based on the International Electrotechnical Commission’s (IEC), and is essentially a classification process rating the degree of protection offered from the security camera against any intrusion by solid and/or liquid matter.  All of our cameras are submersion tested and an IP rating of 68 essentially ensures that our cameras are protected from total dust ingress and protected from long term immersion up to a specified pressure.  The V-Pro is a nitrogen filled camera, giving it a 69IP weatherproof rating, which ensures protection from total dust ingress and close range high pressure, high temperature spray downs.
