The principle of outdoor camera waterproof detection is to use the negative pressure test principle and take dry compressed air as the medium to carry out outdoor camera waterproof detection on products. Generally, a sealed mold is made according to the shape of the product to be tested for outdoor camera waterproofing (the wiring harness needs to be slotted), so that after the outdoor camera waterproofing test mold is closed up and down, the outdoor camera waterproofing tester can detect the change of air pressure inside the mold with precision sensors to judge the air tightness of the product.
