By: Ángel Díaz In every age, police forces gain access to new tools and technologies that may advance their mission to prevent and combat crime. The deployment of new technologies requires an understanding of their impacts on the fundamental rights of the communities that police serve and the development ofContinue Reading

Faster than the Human Eye! Higher Speed with Column-parallel A/D Conversion and Reducing Noise The key to increased speed of Sony’s CMOS Image Sensor can be found in parallel signal processing. CMOS sensors have analog-digital (A/D) conversion circuits that convert analog pixel signals into digital signals (Figure 1). Speed isContinue Reading

Greater Sensitivity than the Human Eye! Back-illuminated structure provides higher sensitivity Sony’s back-illuminated CMOS image sensor improves sensitivity and noise reduction – the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained the advantages of CMOS image sensors suchContinue Reading

Adding Functional Value to a CMOS Image Sensor that Exceeds Human Vision! Back-illuminated and stacked structure provide advanced functionality Stacked CMOS Image Sensor is a Sony’s CMOS image sensor that adopts a unique ‘stacked structure.’ This structure layers the pixel section, containing formations of back-illuminated pixels over the chip affixedContinue Reading

What’s SLVS-EC? Scalable Low-Voltage Signaling with Embedded Clock, abbreviated SLVS-EC, is a high-speed interface standard developed by Sony for fast, high-resolution image sensors. The interface’s simple protocol makes it easy to build camera systems. Featuring an embedded clock signal, it is a good choice for higher speeds or transmission overContinue Reading

DOL-HDR DOL-HDR: Digital Overlap High Dynamic Range In the DOL-HDR technology, an image processing technology for subjects with high contrast. It synthesizes different exposure conditions into an image so that both bright and dark data can be seen at the same time.Therefore, it outputs brilliant colors are captured even whenContinue Reading

Calling all tech geeks! We know that some of you are curious about how, exactly, Dahua’s optimized video compression codec, Smart H.265+ works. Here are four innovative things it does to reduce bitrate and storage requirements. Scene-Adaptive EncodingA typical surveillance scene is not fixed; the scene is constantly in fluxContinue Reading

Application: You need to install a camera in the lobby of a building to capture the entrance area. Problem: The application has a lot of windows which over exposes the image making it difficult to capture who is coming and going. Solution: A security camera with good Wide Dynamic RangeContinue Reading

Clear video images in low-light scenarios are a must for many security installations. With the abundance of options on the market, however, it can be confusing to figure out which kind of technology to use. Here, we take the mystery out of low-light technology and give you practical information toContinue Reading
