AXIS Q1942-E

توضیحات محصول

AXIS Q1942-E lets you accurately detect, promptly verify, and then act upon events of all kinds in conditions ranging from pitch darkness to glaring sunlight. It is perfect for surveillance in critical circumstances.

A video analytics powerhouse

AXIS Q1942-E’s powerful processor lets you add the strength of the market’s widest selection of video analytics solutions to your surveillance solution. For example, video analytics applications from Axis and our partners support swift and appropriate response to detected events by analyzing them, automatically dismissing non-threatening ones and instantly notifying security staff of potentially critical situations. Your staff can then view sharp, detailed footage to determine the precise nature of the threat – and act accordingly.

Far + wide + sharp = accurate

AXIS Q1942-E features VGA 640×480 thermal resolution for wide-area coverage and a long range: in other words, a single camera captures events taking place in a large area and at great distance. In addition, thanks to a combination of dynamic histogram equalization, enhanced local contrast and dynamic sharpening, AXIS Q1942-E improves image contrast for sharp video with great detail in all conditions. And Electronic image stabilization keeps the picture smooth even when the camera is exposed to vibrations.  The result is outstanding detection capabilities and fast and easy visual verification of the nature of detected events. You can either dismiss them – or do something about them – so false alarms are kept to a minimum.

Sharp images.

Thermal cameras are a powerful tool in combination with video analytics to detect intruders or other unwanted behavior in the area of interest. In order to have a reliable and efficient surveillance system, the primary object needs to be visible. Sometimes it can be hard to filter it out if the background changes a lot, for example if large cold/hot objects are moving in the scene. Thanks to the enhanced automatic gain control in AXIS Q1942-E, the background is stable and remains almost intact, reducing the risk for false alarms. The effect of hot objects in the background is minimized, helping to improve detection. In addition, AXIS Q1942-E preserves more image details and compensates those areas that might be overexposed. Overall, the thermal camera offers better detection to achieve great performance of the video analytics.

Low bandwidth and storage.

Hand squeezing lemon

AXIS Q1942-E is equipped with Axis’ Zipstream technology, which reduces storage and bandwidth requirements, while capturing important details in full image quality. It does this by compressing less significant areas more than areas of interest. In other words, areas devoid of people or movement are compressed more. This can be particularly relevant to applications where thermal cameras are likely to be used, since these are often applications in areas where access is highly restricted.
