VIZBOX® Enclosures protects projectors do not allow water in. The IP rating certificate demonstrates that the housing has had water sprayed at it from all angles and has not allowed any water inside the unit. Is it waterproof then?
ALL outdoor enclosures which are specifically designed to protect electrical products inside, from the elements outside, MUST have cable entry points, AND vents to allow air into the unit. Hence if you held a high-pressure water hosepipe against the unit,at every possible degree, water could possibly enter the housing.
To all intents and purposes VIZBOX never allows water into the unit, but strictly speaking and in technical terms, it is impossible for any projector enclosure on the market to be waterproof. VIZBOX is the brand to trust, being IP rated AND CE-Marked.
