As security products that can be monitored at any time, cameras have the characteristics of high sensitivity, resistance to strong light, small distortion, and precise structure.Whether it is a conventional security camera or a high-definition vehicle camera, they are all assembled from components such as lenses, lens sheets, and chips. In order to ensure its normal use, people usually make a highly waterproof precision housing for it and conduct waterproof testing for it.Testing the waterproofness of the camera and its peripheral products can prevent water mist from entering the camera during use, causing lens damage or the entire camera being scrapped.

Hirays Technology has done a lot of research in the field of waterproof testing and has formulated different testing plans for different products. Today we will share the waterproof testing in the field of security cameras, hoping it will be helpful to everyone.

1. Requirements for waterproof testing in the field of security cameras

1. With the advancement of technology, cameras have begun to evolve into different models and types. In addition to conventional security cameras, there are also vehicle-mounted cameras and high-definition cameras. The detection methods will be different for different shapes and structures;

2. Due to the particularity of this product, the non-destructiveness, safety, and accuracy of the test results should generally be considered during testing.In order to ensure the safety of the test, dry and impurity-free gas can be used to act on the inside of the product, which places very high requirements on the operating instruments and operators.

3. For camera products with strong sealing and no obvious air outlet, we can use indirect inspection methods; for those that are smaller in size but require batch inspection, we can use multi-channel and multi-station simultaneous inspection methods;

4. Cameras with special shapes need to prepare special tooling equipment, or observe whether there are interfaces inside the product that can directly connect to detection equipment.

two, Share the application examples of Hai Ruisi waterproof tester in the field of security cameras

1. In addition to detecting the camera, security cameras also have related peripheral products, such as connecting wires, etc. The waterproofness of the wires is best realized by clamping the joint in the slot along with the tail section of the wire, hanging from the outside of the mold, while the front end of the entire wire is folded around and placed in the mold. As long as it is fixed and the upper and lower molds are closed, the air tightness can be judged by the air pressure inside the mold;

2. Conventional cameras have high precision and have no air outlet, so the indirect waterproof detection method is used. After the mold is closed up and down, the air tightness of the product can be judged by the air pressure inside the mold.

3. Advantages and parameters of waterproofness tester

1. High-sensitivity pressure sensing and adjustment unit, combined with advanced differential pressure software algorithm, the minimum resolution can reach 0.1Pa. This algorithm has obtained a national patent.

2. Patented technology independently developed by Hirays,"IVT pneumatic sealing valve island", greatly improving the test accuracy, ensuring the stability of the instrument, and the inflation speed is also greatly improved.

3. Multiple test functions: The instrument integrates two pressure forms, positive and negative, and 8 test methods: two pressure forms and five test methods can be programmed into more than 20 test functions.

4. It has more than 200 groups of subroutines. Each group of subroutines can be programmed independently, single selected and combined to meet various complex testing requirements.

5. Full-touch large-screen intelligent operating system, graphical UI design based on the detection process, the operation interface is simple and clear, easy to teach and learn.

6. A variety of pressure adjustment components and ranges are optional, with a wide air pressure range (-80KPA—1MPa) optional.The optional electronic pressure regulating valve can realize multiple sets of pressure sequential tests.

7. Multiple communication interfaces: built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supporting multiple communication protocols.

8. Optional barcode scanning function and printer are available to facilitate product data management and quality traceability. The instrument history record can reach up to 200,000 items and can be exported to the computer in batches.

9. The standard volume identification function can automatically identify the volume of the sample to be tested, and measure and judge the leakage rate in a volumetric manner.

10. Ultra-high stability and ease of use have passed the rigorous test of the market.

11. A variety of accessories are available, including inflatable bypass, quick connector, and standard leak hole. At the same time, the instrument supports third-party calibration and can issue a calibration report.
