The need for a surveillance camera strategy

As surveillance systems advance from being simply passive observation windows to becoming active agents that incorporate such advanced technologies as facial recognition, parcel detection, and traffic flow management, they require increasingly advanced camera technology. Similarly, aerospace and defense applications are increasing their use of advanced camera-based capabilities that require specialized knowledge and experience.

Extreme conditions combined with uncompromising video quality goals make surveillance camera design a unique challenge

Effective surveillance requires seeing all elements of a scene in lighting conditions that potentially range from complete darkness to bright daylight. In addition, they often need to handle intense back lighting. As a result, many surveillance applications require integrating multiple sensors, including near-IR and thermal sensors, with visible light cameras, as well as with multi-frame or other HDR solutions.

With the growing popularity of automatic image analysis, surveillance cameras need to be optimized for both human and computer vision, including input to AI-based analysis systems. Given the large amount of data that cameras capture, the intelligent compression of the data stream without sacrificing important information is also a key element. Depending on specific circumstances, many surveillance systems also need to be able to support deployment in harsh conditions, including rain and snow.

DxOMark Solutions and Services

Our experience in designing multi-camera systems for a variety of industries makes DxOMark an ideal partner for your surveillance camera projects. Specifically, we offer:

Consulting and Benchmarking: We can help your team with its camera architecture and product design choices, as well as with creating vendor specifications, performance goals, and milestones. We can assist in every stage of the development process, including the tuning and integration of your device; further, we can also compare prototypes and production units with those of competitors and against your own KPI milestones. We can provide in-depth evaluation of such various surveillance systems as indoor fixed-focus cameras to outdoor PTZ cameras. Learn more. 

Analyzer: We also offer Analyzer, a complete hardware and software lab and measurement solution that caters to component-level and system-level measurements. In particular, you can use Analyzer to evaluate camera color, texture, and contrast performance in HDR and extreme low-light conditions. Given the environments in which they often operate, good video stabilization a key component for surveillance cameras, as they are susceptible to being swayed by the wind or shaken by heavy vehicular traffic (for example). Further, surveillance camera systems have to perform well in wide-angle shots to avoid distortions and to have coherent and uniform performance all across the field. Analyzer not only helps you evaluate these image quality attributes, but also tests automatic white balance, automatic exposure, texture, noise, and stabilization under challenging lighting scenarios simulated by our Automated Lighting System. Learn more.
