High-definition cameras generally play a role in security detection. High-definition cameras are installed in many public areas: such as in schools, parks, or in all directions on buses.High-definition cameras installed outdoors need to work around the clock in harsh environments and need to be waterproof. Otherwise, the lens is prone to water intrusion and fogging, which affects the clarity and accuracy of surveillance videos.

For high-definition cameras for outdoor use, the waterproof level requirement is generally IP67. IP67 refers to the protection safety level.It defines a product's ability to protect against liquid and solid particles. IP67 waterproof camera means that without damaging the casing, 6 means that the product can completely protect the internal circuitry from dust intrusion, and 7 means that the camera can protect the internal parts for no less than 30 minutes when immersed in water no more than 1m deep.

This time we are going to make an IP67 waterproof testing equipment for this high-definition camera. As can be seen from the appearance of the product, this one needs to beWaterproof testThe camera does not have any inflatable port, and there is a wire at the end of the product. This wire does not need to be tested for waterproofing.So we need to make a test mold for the product, and at the same time, we need to reserve a wire trough on the mold and put the wire outside the mold.As shown below:

The waterproof level to be tested for this camera is IP67. According to the IP67 level standard, the test pressure is 10.5kpa. This test pressure is equivalent to the pressure the product will bear under one meter of water.The air intake time is 3s, the pressure stabilization time is 5s, and the test time is 5s. The maximum allowable leakage is 0.02kpa, which is equivalent to 20 Pa.

Connect the air tightness testing tooling and the Hirays air tightness testing instrument together through the factory air source, plug in the power, and start the IP67 waterproof testing of the camera.

This time the customer choseAir tightness detectorIt is the latest HL Leader series air tightness testing instrument from Hirays.The HL Leader Series Air Tightness Tester is the latest product launched by Hirays. It is a product that brings together many years of experience and technology of Hirays and incorporates the genes of future intelligence.A high-end instrument developed mainly for high-precision multiple pressure requirements and complex testing processes.
