Avoid false alarms with our image stabiliser!


Video surveillance systems must ensure maximum accuracy so as not to miss real detections and avoid false alarms as much as possible. When designing a CCTV system, basic aspects such as securing blind areas and placing cameras at certain heights and angles must be considered; but also knowing how to choose the best technology in both hardware and video analytics systems.

Therein lies the biggest challenge: relying on state-of-the-art technology that gives access to sharp images and enables alerts to be triggered as soon as suspicious situations are detected.

Perimeter security systems, where cameras are installed outdoors, require advanced functionalities to ensure total reliability. Our DFUSION video analytics systems feature an image stabiliser, ideal for avoiding camera shake. CCTV cameras mounted on raised poles, walls and other parts of the perimeter are exposed to strong winds, rain and other adverse conditions that can cause cameras to vibrate.

In addition, the use of narrow perspective optics to cover long distances increases camera sensitivity. The slightest vibration generated by the environment (wind, rain, etc.) has a huge impact on the scene and affects video analytics systems. What are the consequences of this type of vibration on the image? Simple: a high false alarm rate, loss of real detections and, as a result, increased security operating costs.

One of the problems that we encounter with CCTV camera vibration is that we can lose control of the detection zone, reducing the efficiency of the surveillance and detection system. Camera shake is a serious problem in outdoor installations, hence the importance of installing equipment on rigid supports and having an image stabiliser.


How do vibrations and tremors affect CCTV security?

When a camera vibrates due to strong winds or tremors typical of the environment (loading/unloading zones, underground subway tracks, traffic, etc.), video surveillance systems may fail because the system stops watching the area of interest or “suspicious” elements are identified outside the defined scene. This could result in:

· Loss of detections in the area of interest, which increases the risk intruders getting in.

· A high number of false alarms because the camera moves and detects outside the area defined by using masks

Vibrations are a serious problem for ARCs as they do not have reliable images for monitoring perimeters and enclosures. Failure to deal with these issues can lead to high operating costs and serious security failures.

That’s why DAVANTIS video analytics equipment has an image stabiliser that makes image analytics algorithms more reliable for detecting intruders and reduces the false alarms caused by camera movement.

In addition, thanks to DFUSION’s dual detection engine, our video analytics system can detect intruders at long distances while partially hidden and in the most challenging conditions.
