Which camera type provides comprehensive coverage but often lower image quality?

• A. Bullet cameras
• B. Fisheye cameras
• C. Dome cameras
• D. PTZ cameras

Answer: (B)

Ultra-wide field of view cameras, like fisheye cameras, are designed to capture a whole space in a single shot. That broad coverage is what makes them ideal for monitoring large rooms or open areas without moving the camera. The downside is image quality: spreading the sensor’s pixels over a very wide angle reduces detail and introduces distortion, especially toward the edges. Software can dewarp or crop the image to view specific regions, which helps, but it doesn’t restore the lost pixel detail across the entire scene. So you get broad situational awareness with one camera, at the cost of lower per-point image clarity.
