  • A Century of Evolution in Security Camera Hardware and Imaging Optics

    The technical trajectory of security cameras was not an overnight success but a cross-disciplinary evolution spanning two centuries. Its roots can be traced back to the late 19th century with the first attempts to capture continuous dynamic images. In 1870, English inventor Wordsworth Donisthorpe patented the "kinesigraph," a moving picture camera designed to take a series of photos at set intervals to capture movement. In 1889, Donisthorpe and Louis Le Prince further refined film cameras and projection technology; Le Prince even developed a 16-lens camera, which, while more of an experimental tool at the time, laid the physical foundation for continuous monitoring in specific spaces.

  • 3 Essential Camera Lenses for Smart Parking Lot Surveillance Systems

    Smart parking systems need more than cameras—they need the right lenses. Explore three essential surveillance lenses from Shanghai Silk Optical designed for coverage, AI recognition, and low-light performance.

  • Understanding the 4mm Security Camera Lens: What It Does and Where It Works Best

    Looking for the right lens for your security camera? The 4mm fixed lens might be the unsung hero you need. Not too wide, not too narrow—it offers the perfect balance for monitoring stores, offices, entrances, and more. In this guide, we break down how it works, where it shines, its few quirks (like distortion), and why it’s a go-to choice for real-world surveillance—no engineering degree required.

  • Why CRA < 15° Is the Secret Ingredient to Flawless 5MP Imaging: A Case Study with PL057

    As an imaging engineer or a procurement manager, you’ve likely seen this heartbreaking scenario: You spend your entire hardware budget on a high-spec 5-megapixel sensor, only to pair it with a mismatched lens and end up with footage that looks like a watercolor painting after a rainy day. You ask your engineers, "Where’s the detail? The specifications said 5 million pixels!" The answer often boils down to a technical metric that isn't as sexy as "megapixel count" or "aperture size," but is arguably just as critical: Chief Ray Angle (CRA). If you are dealing with high-resolution sensors, and your CRA isn't under control, your megapixels are being wasted. Here is the plain-English explanation of why CRA matters for 5MP imaging, and how a precision-engineered lens like our PL057 provides the ultimate solution.

  • MTF Testing Explained: How Engineers Evaluate Lens Performance

    MTF (Modulation Transfer Function) testing measures how well a lens transfers contrast and detail to the sensor, revealing true optical resolution beyond megapixel counts. Engineers evaluate center, edge, and mid-field performance using controlled patterns. MTF curves show contrast retention at fine detail levels. This matters for security, industrial vision, robotics, and medical imaging, where clarity affects detection and accuracy. MTF is one of several tests—alongside distortion, chromatic aberration, and flare—used to ensure reliable real-world performance. Boshi Optics prioritizes balanced optical design and consistent manufacturing for dependable imaging.

  • Add new equipment and expand production capacity-Optical lens manufacturing

    In November 2023, the production of various types of lenses (security monitoring, car mounted lenses, starry lenses, etc.) at the direct factory of Shanghai Boshi exceeded 5.5 million. In December, to meet the order demand, new equipment was added and preparations were made in advance for production next year.
