From low to high resolution, from big to small;

From single function to multi-function, from just for sports events to family action camera.

These all indicate that the market for action cameras is constantly expanding, and the various performances of action cameras are constantly improving with the changes in usage scenarios, especially the demand for waterproof performance.

Action cameras are mostly used in outdoor environments. If it rains suddenly or needs to be put into the water, if the air tightness is not good, it is likely to be immersed in water vapor, which will affect the service life of the internal components.

Businesses with high requirements for air tightness will use materials such as waterproof silicone rings, RTV silicone glue, PUR hot melt glue, etc. to make the waterproof level of the action camera reach IPX7 or even IPX8.

Therefore, the overall waterproofing of an action camera and the airtightness testing of its components are crucial. How do we test its airtightness (waterproofing)?

Compared with traditional water immersion and spray testing, air tightness testing has an easy-to-generate testing environment and is more efficient and more accurate.And after the inspection is completed, there is no need to perform operations such as drying, which is more suitable for the current efficient production rhythm.

Before performing waterproof testing on action cameras, you must first know that waterproof testing on action cameras is divided into structural air tightness testing and waterproof and breathable membrane air tightness testing.

Before starting the inspection, customize the fixtures and tooling according to the style and structural characteristics of the product to be tested。

1. The test pressure is from10Kpa to 100Kpa, and the parts contain plastic, which can easily deform under excessive pressure;
2. There are two breathable membranes on the same surface that need to be tested at the same time, but there is a height difference.

Connect the air source and power supply, connect the action camera or other components to the instrument, select the set program, and start testing.

The instrument will definitely determine whether the product under test is OK or NG according to the set program.
