What type of camera is most often used for close-up shots in surveillance?

The correct answer is that the bullet camera is most often used for close-up shots in surveillance due to its design and practical features. Bullet cameras are typically compact, cylindrical, and can easily be mounted on walls or ceilings, making them suitable for discreet surveillance in various settings. Their shape allows for easy focusing on specific areas, which is ideal for close-up shots.

Additionally, bullet cameras often come with a varifocal lens option, allowing for adjustable focal lengths. This adjustability enhances their capability to zoom in on specific subjects or areas of interest, making them particularly effective for close-range surveillance tasks, such as monitoring entry points or capturing clear images of a specific area.

While pinhole cameras are also designed for discretion, they generally provide a very limited field of view and are not as versatile for close-up monitoring. Infrared cameras are focused on capturing images in low-light conditions and do not specifically cater to close-up shots. Box cameras, while versatile, are bulkier and not as suitable for close-up applications as bullet cameras.
