Which camera has a fixed field of view and lacks infrared LEDs?

The camera characterized by a fixed field of view and the absence of infrared LEDs is the multi-sensor camera. This type of camera typically offers a wide monitoring area through several sensors pointing in different directions, allowing it to cover more ground without the necessity for infrared illumination, as it is designed to operate well in well-lit environments.

Each type of camera has its unique focuses and features. Multi-sensor cameras specialize in providing a broader perspective with their multiple lenses, making them effective for large areas without the ability to pivot or zoom, which is coherent with having a fixed field of view.

In contrast, dome cameras often have a fixed lens but can sometimes feature IR LEDs depending on the model and the intended use environment. Bullet cameras, known for their long-range capabilities and usability in various lighting conditions, typically come with IR LEDs to handle nighttime conditions. Positioning cameras are designed for dynamic control, providing the ability to pan, tilt, and zoom, hence they cannot be classified as having a fixed viewpoint.

Thus, identifying the multi-sensor camera recognizes its specific characteristics that set it apart from other camera types within the options provided.
