A reversing camera is a car camera that is installed at the rear of the car.Combined with the display screen installed in the car, it forms a complete reversing imaging system. When reversing, the driver can grasp the overall environment behind the car body and avoid injuring people or damaging objects when reversing.

The reversing camera is usually installed on the license plate light housing at the back of the car or fixed on the rear bumper of the car.In heavy rain or when washing the car, the rainwater can easily wash away the reversing camera.If the waterproof level of the camera does not meet the requirements, water will enter the inside of the camera.Water mist inside the camera will cause the lens to blur, seriously affecting the driver's vision and posing safety risks.

Therefore, reversing camera manufacturers will waterproof the camera, usually using glue to seal the inside of the camera.The sealed reversing camera needs to be tested for air tightness to check whether it reaches the waterproof level of the reversing camera.Unqualified products must be repaired or technical support provided for subsequent technical improvements.

Manufacturers generally choose air tightness detectors to perform waterproof testing on cameras.The air tightness testing equipment can be made into non-standard air tightness testing equipment according to the customer's products, and it can also be made into multi-channel air tightness testing equipment according to the customer's output.Multiple products can be tested at the same time to meet customer needs for high efficiency.

The reversing camera we tested this time is because the use environment of reversing cameras is relatively changeable, and the safety requirements of vehicle accessories are relatively high.The customer's waterproof level requirement for this product is IP68. The test pressure used is 100kpa.

The inflation time is 5s, the voltage stabilization time is 5s, and the test time is 5s.The air tightness detection time of a reversing camera is 15 seconds.

Connect the air tightness detector and the tooling through the RS485 terminal interface, and connect the power supply and air source at the same time.Adjust the test pressure of the air tightness detector to the 100kpa we need, and then start the waterproof test of the reversing camera.

The waterproof tester used this time is oursHC Classic Series Waterproof Tester.It has been updated many times by Hirays Technology.This instrument is the most chosen by customersAir tightness detector.It comes with positive and negative test pressures and adopts imported Honeywell pressure sensors. The sensor accuracy can reach 0.2% FS.Fairchild pressure regulating valve imported from the United States is used, and the air tightness test is stable.This HC classic air tightness tester has stood the test of time and has been used in thousands of factories and is highly recognized by customers.
