ANVE Exam Dumps : Axis Network Video Exam

A visual camera enables the detection and identification of a person’s face. Visual cameras capture detailed images using visible light, which is necessary for facial recognition and identification applications. While radar, passive infrared sensors, and thermal cameras are useful for detecting movement and heat signatures, they do not provide the detailed imagery required for facial identification. This functionality is detailed in Axis Communications' documentation on camera capabilities.

When dealing with a poorly lit scene, adding light is the most effective option to improve image quality. Proper illumination ensures that the camera's sensor can capture clear and detailed images, reducing noise and enhancing visibility. While adjusting exposure settings, brightness, or changing camera placement can help, they are secondary to the fundamental requirement of adequate lighting.

The IP51 and IP52 ratings indicate that the camera is protected against dust and dripping water. IP51 means the camera is protected against dust ingress to a level that would interfere with the operation and against vertically dripping water. IP52 offers the same dust protection but also protects against dripping water when tilted up to 15 degrees. These ratings make the cameras suitable for indoor use where dust and minor water exposure might occur. Axis Network Video documentation specifies the IP rating system and the levels of protection provided by different ratings.
