The Camera Sensor OV7251 is a low-light camera sensor produced by OmniVision Technologies, primarily used in applications like security cameras, robotics, and some embedded systems. It captures high-quality images even in low-light conditions. The OV7251 itself is the sensor hardware, and to interface with this sensor in a Windows environment (e.g., for capturing images or video), you need the appropriate driver and software that communicate with the sensor through the device.
