- PTZ Cameras: Pan-Tilt-Zoom cameras can be remotely controlled to move left, right, up, down, and zoom in and out.
- C-Mount Cameras: These cameras allow for interchangeable lenses, which can be customized to different applications.
- Infrared/Night Vision Cameras: Equipped with IR LEDs, these cameras can capture footage in low-light or no-light conditions.
