Zooming in to the right Videology Zoom Block camera for Intelligent Transportation Systems

Zoom block cameras offer a combination of compact size, high-quality imaging, and ease of integration.  Their optical zoom technology brings many advantages such as clearer and sharper images, preserving fine details in various lighting conditions, from bright sunshine to dark environments. All these benefits make zoom block cameras a preferred choice for OEMs and system integrators looking to embed cameras into their Intelligent Transportation System (ITS) solutions. 

With optical zoom levels of 10x to 55x, zoom block cameras play pivotal roles in Intelligent Transportation Systems and traffic management solutions. Optical zooming allows block cameras to achieve a variable focal length, enabling them to capture clear and detailed images even from a distance. This is particularly important for today`s advanced traffic systems that monitor highways, intersections, parking areas, etc.

Key imaging requirements for traffic and transport applications

Cameras integrated into smart traffic systems provide real-time traffic insights and have a crucial role in optimizing traffic flow and monitoring safety, speed, and traffic violations. By capturing high-resolution images, these cameras become the "eye" for traffic management authorities to monitor and analyze traffic patterns, detect incidents, and make informed decisions to ensure smooth and safe movement of vehicles on highways, intersections, and parking areas.

With advanced features such as low light sensitivity, WDR, and global shutter sensors, zoom block cameras deliver accurate, real-time, and reliable imaging data that is essential for efficient traffic management and incident detection. By continuously monitoring and analyzing traffic conditions, our cameras help identify congestion points, improving traffic flow, and enhancing overall system performance in intelligent transportation systems. 

Let's take a closer look at some features zoom block cameras offer that are vital for most traffic and transportation applications. 

Integration with Artificial Intelligence (AI) on the Edge

In anticipation of advancements in AI-based imaging solutions, Videology has taken a significant step forward by integrating Edge AI into its zoom block camera line. The on-camera AI capabilities of SCAiLX technology allow for real-time image and video analysis without transmitting data to the cloud.

Further developments in SCAiLX technology have opened up Edge AI-powered image analysis options for already installed block cameras (with LVDS output) from other leading brands such as SONY and Tamron.

Artificial Intelligence is already a key player in enhancing Intelligent Transportation Systems (ITS) across various modes of transportation, including rail, road, and air. Utilizing block cameras with AI-powered image processing and analytics capabilities is a highly effective way to enhance the efficiency and effectiveness of these systems.

Optical zooming and autofocusing

Autofocusing complements optical zoom by automatically adjusting the focus based on changes in the scene or the movement of objects, ensuring that the camera maintains sharp and clear images without the need for manual intervention. This is especially beneficial in rapidly changing scenarios, where quick and accurate adjustments are essential for real-time analysis. Together, optical zooming and autofocusing enhance the capabilities of zoom block cameras in ITS, contributing to improved traffic management, incident detection, and overall system reliability.

Latency

Another critical metric for ITS camera solutions and applications is the latency of the system. Namely, the time it takes to respond and process video data and provide information. The end-to-end system, starting from latency in the camera to the latency in the network and client side, must have low values. Videology block cameras have latency <1 fps, which is as low as 33ms, depending on the chosen frame rate and complexity of the image processing features. These block cameras are engineered with advanced hardware and firmware optimization, reducing the delay between image capture and processing and enabling quicker detection and analysis of events such as traffic congestion, accidents, or violations.

Wide Dynamic Range (WDR) and Digital Noise Reduction (DNR) 

Outdoor environments often undergo dynamic shifts in lighting, transitioning from intense sunlight to shadowy areas, and even artificial illumination at night. WDR and DNR technology on zoom block cameras help to maintain visibility under these rapidly changing light conditions. 

WDR on zoom block cameras ensures that when images have been taken under conditions with both bright and dark areas, the image is free from loss of detail in overexposed or dark areas. This is achieved by combining a multiple number of images, shot at different exposure durations. An optimum fusion ratio is applied when combining the high-speed shutter used in bright areas and the low-speed shutter used in dark areas. 

DNR technology, on the other hand, eliminates noise thus generating a distinct and clear image. Zoom block camera`s DNR function utilizes both an adaptive 2D filter reducing noise in the brightness
of the image and an adaptive 3D filter reducing noise caused by movement.

The capability of a camera to deliver clear and detailed images in challenging low light conditions, preserving clarity and reducing noise in the final output, is known as low light performance. Zoom block cameras optimized for low light settings, excel in providing top-quality images even in the darkest environments.

Connectivity and controls

Videology zoom block cameras are typically controlled via the VISCA protocol. Most zoom block cameras also support PELCO-D, PELCO-P, and UTC (Up The Coax) control (Pelco-C). They also comply with multiple output options, such as LVDS, HD-SDI, EX-SDI, CVBS, HD analog, and IP output. 

It is crucial to assess which type of output and connectivity will best suit your requirements. Be sure to verify this when selecting a zoom block camera.
