Application examples of waterproof detector in various camera fields

As security products that can monitor at any time, cameras have the characteristics of high sensitivity, strong light resistance, small distortion and precise structure. Whether it is a conventional security camera or a high-definition car camera, they are all assembled by lens, lens piece, chip and other components. In order to ensure its normal use, people usually make a precise shell with strong water resistance for it, and test its water resistance. Waterproof detection for its and its surrounding products can prevent the camera from entering water mist when it is in use, causing damage to the lens or scrapping of the whole camera.

Hiris technology has made a lot of research in the field of waterproof detection, and has developed different detection schemes for different products. Today, we will share the waterproof detection in the field of security cameras, hoping to help you.

1、 Requirements of waterproof detection in security camera field

1. With the progress of science and technology, cameras begin to evolve into different models and types. In addition to the conventional security cameras, there are also car cameras and high-definition cameras. For their different shapes and structures, the detection methods will be different;

2. Due to the particularity of the product, the nondestructive, safety and accuracy of the test results should be considered when testing. In order to ensure the safety of the detection, dry gas without impurities can be used to act on the product, which has high requirements for the operation equipment and operators.

3. For camera products with strong sealing and no obvious air outlet, we can adopt indirect detection method; If the volume is small, but there is a need for batch detection, multi-channel and multi station simultaneous detection is used;

4. For the camera with special shape, it is necessary to prepare special tooling equipment, or observe whether there are interfaces in the product that can directly connect with the detection equipment.

twoShare the application examples of Harris waterproof detector in the field of security cameras

1. In addition to the detection of the camera, the security camera also has its related peripheral products, such as connecting wire, etc. the waterproof detection of wire is the best way to realize. The connector will be stuck on the card slot with the tail section material, hanging on the outside of the mold, while the front section wire will be folded and surrounded, and placed in the mold, as long as it is fixed, When the upper and lower molds are closed, the air tightness can be judged by the air pressure inside the mold;

2. If the conventional camera has high precision and no air outlet, 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 waterproof tester

1. High sensitivity pressure sensing and regulating unit, combined with advanced differential pressure software algorithm, the minimum resolution can reach 0.1pA, which has won the national patent.

2. The patented technology of "IVT pneumatic sealing valve island" independently developed by Harris greatly improves the test accuracy, ensures the stability of the instrument, and greatly improves the inflation speed.

3. Multiple test functions: the instrument integrates two positive and negative pressure forms and eight test methods: two pressure forms and five test methods can be written into more than 20 test functions.

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

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

6. A variety of pressure regulating components and ranges are available. Wide range of air pressure (- 80kPa & amp; mdash; 1MPa) optional. Selecting electronic pressure regulating valve can realize multi group pressure sequence test.

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

8. Bar code scanning function and printer can be purchased to facilitate product data management and quality traceability. Up to 200000 historical records of the instrument 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 the way of volume.

10. Ultra high stability, and ease of use, after a rigorous test of the market.

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