What is the pixel density required to identify individuals in challenging conditions according to Axis?

The correct requirement for pixel density to effectively identify individuals in challenging conditions, as indicated by Axis, is 500 PPM. This specific pixel density is recognized as the optimal standard for ensuring recognizable details, such as facial features or clothing characteristics, which are essential for accurate identification. In challenging conditions—where visibility may be impaired due to lighting, distance, or obstruction—having a higher pixel density allows for greater clarity and detail, enhancing the effectiveness of video surveillance systems.

Lower densities may not provide sufficient detail needed for identifying individuals, especially when the footage is analyzed for purposes such as law enforcement or security assessments. Hence, 500 PPM is the benchmark that organizations should aim for to maintain security efficacy in various environments.
