Kingvee has the core technology research and development capabilities. The Kaiwei HD infrared camera is leading the market with perfect effects, solid product manufacturing strength, and large system solution capabilities. It is one of the leading security companies in the security industry. The company's goal is to provide customers with a comprehensive, multi-functional, comprehensive security industry chain service platform that plays and plays an extremely important role and function in security monitoring applications and security management in various industries.

Relying on Kaiwei's strong brand awareness and R & D and manufacturing capabilities, through the efficient marketing network of thousands of highly qualified engineering partners across the country, Kaiwei's security surveillance products in China are driven by strong market promotion and operation management. The market's sales volume has increased significantly each year, and Kaiwei has become a significant brand in China's video surveillance industry.

Kaiwei / Kingvee HD Quality Control Center

Quality Control Center: The quality control center of Xinzhiheng Technology Co., Ltd. currently has a total of 30 professional inspectors of various types and strictly abides by the company's quality control system. The company has a 200 square meter professional aging room equipped with professional aging instruments; all series of products must be subjected to 8 hours of high and low temperature live aging. During the aging process, the temperature and humidity of the aging room are strictly controlled; Under the strict inspection of the company's quality inspectors, all products of the company must undergo 4 inspections: 1. Raw material incoming inspection; 2. Semi-finished product inspection; 3. Finished product inspection; 4. Factory inspection; Meet customer requirements for company product quality.

One. Incoming raw materials inspection Incoming components inspection: testing capacitance, resistance, inductance, triode LED testing machine: Incoming inspection of infrared lamps

  


two. Semi-finished product testing for high-temperature baking: After cleaning all the movements, power boards, and light boards, they must be baked at a constant temperature of 70 degrees for 8 hours to ensure the stability of the movement, power boards, and light boards.


The finished semi-finished product needs to be inspected first (testing for clarity, infrared effect, various electrical parameters)


three. Finished product test
1. Rain test: All submersible test systems for waterproof products, simulated rain test

  


2. Water immersion test: All products are submerged water test system and simulated rain test system.


3. Whole machine aging: The company has an aging room of 100 square meters. The product must be aged at 70 ℃ and -25 ℃ for 12 hours before it leaves the factory.


4. High voltage test: All input AC220V products must be tested with high voltage (4500V, 3S, 10mA) to ensure that there is no leakage, so that customers are absolutely safe to use!


Kaiwei Kingvee Manufacturing Center

Production assembly: All incoming materials and semi-finished products manufactured will be assembled after passing the inspection. The company currently has 12 production lines with 260 production staff and an average monthly output of more than 50,000 units.
One. Kaiwei production workshop


two. Main station operation process
1.CCD switching filter baking

  


2. Ultrasonic cleaning: All movements, power boards, and light boards need to be cleaned.


3. Cleaning process: Avoid white fog and short circuit on the glass after the camera is working.

Kingvee product core technology and patented product

1. Dual filter switching At present, various commercially available surveillance cameras will produce color cast, whitening and out-of-focus when monitoring the captured image during the day. Our company uses a stable high-quality filter automatic switcher on the CCD chip to correct the problem of color cast and out of focus, so that the captured image is not out of focus, no color cast, and it can filter the strong light to make the screen color more Gentle, to achieve consistent visual color of human eyes.


2. The dual-plate movement adopts SONY standard design. The movement plate uses the front and rear double plates. The front plate is mainly used for video capture, and the rear plate is mainly used for image processing. The perfect design, high stability and more reasonable structure.


3. High-line infrared low-light Use the latest generation CCD of Sony supper HAD CCD II, the sensitivity is increased by 2 times, the minimum illuminance of A series is 0.03 ns, and the C series is 0.01 ns; truly high definition , A The resolution of the series can reach 540TVL and 470K pixels. With the latest generation of SONY DSP, the use temperature is reduced, the accuracy and dynamic range of digital-to-analog conversion and the degree of color reproduction are improved. From the above points, we can see the effects that can be achieved with this new generation of CCD cameras. Even at night, the camera can still obtain high-definition image quality through a faint light source. With the use of our filter switching components, the day and night picture can be almost perfect.


4. Constant current and constant voltage Kaiwei Kingvee camera is the first in the industry to propose the use of a separate power supply for infrared cameras. The power and video are separated so that the high voltage will not interfere with the video imaging effect.

5. Anti-fog design Fog phenomenon will occur when using all kinds of surveillance cameras on the market. Xinzhiheng Technology Co., Ltd. has found through experiments that this fog phenomenon is caused by infrared lamp board, movement board and power board. The rosin acid soap in the medium is heated to form a white mist when it is fingered. The core plates and infrared lamp plates of all of our products are cleaned with our specific washing water to remove the remaining rosin acid soap, thereby completely Solve the phenomenon of fogging.


6. Infrared lens The infrared lens used by Xin Zhiheng Technology Co., Ltd. has different optical path designs (spectral range 400-860mm) and different optical paths (different glass slides for accurate imaging). At the same time, special coatings and mechanical structures are used to suppress Useless light, our company's dedicated lens is not recommended to switch to other brands of products; nor is it recommended that customers replace it by themselves. To change the focal length of the lens in engineering, you can only change the whole machine. Customer focusing is not recommended (because customers do not necessarily have darkroom and other test environments), but if the factory state deviation is large, you can focus in a small range, otherwise it is difficult to adjust the "day and night aberration" to the optimal state.
