In the field of security monitoring, the lens acts as the "eye" of the camera, with its parameters directly determining the quality and practicality of surveillance. Faced with a wide array of lenses on the market, terms like focal length, aperture, and resolution often seem daunting to general users. This article demystifies these core parameters, explains their interrelationships, and provides selection recommendations for different application scenarios, helping you make informed choices.

In the evolution of minimally invasive medicine, the medical endoscope serves as an indispensable tool. This precision instrument combines optics, mechanics, and electronics to allow doctors to observe and treat internal organs in real-time without large surgical incisions. As we enter the era of precision medicine, clinical demands have become nearly paradoxical: lenses must be compressed to sub-millimeter or even micron scales to navigate tiny vessels, yet they must maintain high-definition or even ultra-high-definition resolution to detect early-stage lesions.1 This tug-of-war between miniaturization and high resolution defines the modern "art of balance" in optical design.

In the field of outdoor security surveillance, waterproof and dustproof ratings are critical indicators of product durability. IP66 and IP67, as mainstream protection standards, often confuse consumers during purchasing. While differing by only one digit, these ratings show significant differences in protection capabilities, applicable scenarios, and price positioning. With the global outdoor surveillance equipment market projected to surpass $325 billion by 2025 at a 12.7% annual growth rate, selecting the appropriate waterproof rating has become essential for ensuring long-term stable operation of monitoring systems.

An ‌endoscope lens‌ is a tubular device equipped with a light that can be inserted into the human body through natural orifices or surgical incisions to observe and diagnose the condition of internal organs and tissues.

If you’re in the security field, you’ve probably heard terms like “Starlight,” “Full Color,” and “Black Light” used to describe cameras. But what do they really mean? In simple terms, these names all refer to technologies that help cameras “see” clearly at night or in low light. When there’s not enough light, cameras generally rely on two approaches to capture usable images: improving the camera’s own ability to capture light, or adding supplemental lighting.
