As a kind of monitoring electronic product used outdoors, outdoor security cameras are used in harsh environments and are often exposed to wind, frost, rain and snow.If the outdoor security camera is not waterproof, it will not only easily cause circuit failure, but also allow water vapor to enter the camera lens, affecting its camera effect.Therefore, the sealing performance and waterproof ability of the instrument are crucial to ensure the safe operation and life of the instrument.Hirays Technology has specialized in waterproof testing equipment for 11 years and has tested cameras of various waterproof levels.Today we will share with you the IP67 waterproof rating test method for outdoor security cameras.

Air tightness test method for outdoor security cameras
It can be seen from the appearance of the product that the product is relatively large and irregular. At the same time, the product does not have any inflation holes. It is necessary to make a mold according to the appearance of the product, and judge the sealing of the camera in the mold by detecting the air pressure changes inside the mold.This method of testing the sealing performance of the product by inflating the mold is called indirect testing. If the test product has an inflation hole, it can be tested by directly inflating the inside of the product.This direct inflation method is direct testing.The Hirays air tightness detector comes with two pressure modes, positive and negative pressure, and 8 basic judgment methods, which can be combined into more than 20 test functions to easily cope with various working conditions and meet your various air tightness testing needs.

Outdoor security camera test parameters
According to the customer's requirements, the waterproof level that the customer wants to test is IP67, the test pressure is 12kpa, the leakage value does not exceed 0.5kpa, and the air intake time is 30s. Because the customer's product is relatively large and the mold is relatively large, the inflation time must be appropriately extended.The voltage stabilization time is 10s and the test time is 5s. The complete test time of a camera is 45s. It can be seen from the product that the product is very large. If a push-down mold is made directly, the tooling will be very high and it will not be convenient for the operator to pick and place the product.Hirays engineers set up this kind of push-pull tooling for the product based on the product characteristics.Very convenient for operators to pick and place.Hirays Technology has always been adhering to the one-stop solution to customers' sealing testing problems and improving every minute sealing testing detail.
