OVERVIEW

Vispect is dedicated to maintaining exceptional standards in product development and manufacturing. The company rigorously adheres to international standards such as ISO and EN for hardware development, ensuring robustness through extensive testing in both in-house and third-party certified labs. Software processes are guided by the V-Model, emphasizing stringent testing phases, including professional team reviews and user feedback to refine product quality.

Manufacturing operations conform to ISO9000 and TS16949 standards, with every unit subjected to rigorous full-function, aging, and vibration tests to guarantee optimal performance and durability. Special emphasis is placed on precision in camera production, critical for effective AI detection.

Vispect's commitment to high standards extends to environmental sustainability, complying with ROHS and REACH directives and using eco-friendly packaging, showcasing its dedication to quality and environmental responsibility.

HARDWARE DEVELOPMENT QUALITY

The Hardware Development team of Vispect adheres strictly to industrial standards and principles throughout the whole development process, from Proof Of Concept prototype, to Engineering Prototype, then to Massive Production preparation, and finally to New Product Introduction onto manufacture line.

The standards include, but are not limited to ISO and EN EMC, EMI, and environmental testing standards. Verification tests are conducted both in our in-house lab and by third-party labs authorized by EN and ISO.

Above: Signal-Grade-Verification shall be applied on Vispect Main Unit hardware design during development.

Above: High-low temperature cycling tests shall be applied on Vispect hardware during development, to ensure the material sustain in extreme working environments.

SOFTWARE DEVELOPMENT QUALITY

Vispect Software Development team follows classic V-Model throughout the whole development process of Vispect Standard Products, from Requirement Design, to System and Architecture design, then to coding, and finally to verification tests.

White box software tests are applied on safety-related modules, while black-box tests applied on other modules. For high-level safety systems, Safety Integrity Level 2 (SIL2) is being followed.

An independent DVT team has been established and professional TestBed has been introduced to ensure the compliance of quality codes.

Besides Design Verification, strict road tests and user feedback also play important roles to quality improvement.

Above: In Vispect, safety-related software modules are to be white-box tested by TestBed.

Above: To guarantee their reliability and robustness, the software for some projects is to be developed by following the classic V-Model.

DVT TEAM

We have an independent Design Verification Testing (DVT) team of experts dedicated to ensuring the highest quality of our equipment and systems. This team is responsible for a comprehensive range of tests, including both black-box and white-box testing. Their expertise and rigorous testing methodologies are integral to verifying the functionality, safety, and reliability of our products before they reach the market. The DVT team operates autonomously to provide an unbiased assessment of our designs, ensuring that every product meets our stringent quality standards.

MANUFACTURING QUALITY

Camera quality is also an important factor of accurate detection. Bias of camera optical center is one of the major defaults that impact performance of AI detection. To ensure camera quality, Vispect adopts Active Alignment in its camera producing process. Optical center distraction has been greatly reduced by Active Alignment comparing with traditional producing processes. An additional quality test is at the last step, to check the quality of each finished camera. Vispect cameras are generally installed outside the vehicle cabin, exposed to heat, cold and sunshine, making water-proof critical. Our cameras are filled with a special adhesive that has a minimal coefficient of expansion, ensuring durability under varying temperature conditions.

Above: For every camera, the bias of its optical central line is to be verified on our test platform before the camera is sealed into the case.

Above: On our SMT production line, the robot is in operation to solder the electronic components onto the PCB.

During the process of manufacturing Vispect Standard Products, ISO9001 and IATF16949 procedures are followed by our production lines, from SMT, DIP and assembly to QC and QA. Every piece of Vispect Host or Main Unit is to go through the Full Function Test by specialized computer software, the Aging Test in heat chamber with loads, and the Vibration Test on shaking platform. The Full Function Test goes through every block of circuits to make sure every part of the product runs well.

Environment-Friendly

We would be proud to announce that Vispect supports and has been complying with ROHS and REACH standards that forbid the use of hazardous materials in electronic parts. Besides, at our best endeavour, recyclable and environment friendly packing materials are used on Vispect product. We won’t stop improving to a higher level.
