Python Code Example

Install OpenCV:

pip install opencv-python

Basic image capture:

import cv2

cap = cv2.VideoCapture(0)
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 1920)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080)
cap.set(cv2.CAP_PROP_FPS, 30)

if not cap.isOpened():
    print("Cannot open camera")
    exit()

print(f"Resolution: {cap.get(cv2.CAP_PROP_FRAME_WIDTH)}×{cap.get(cv2.CAP_PROP_FRAME_HEIGHT)}")

while True:
    ret, frame = cap.read()
    if not ret:
        break
    cv2.imshow('USB Camera', frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

Multi-camera selection:

import cv2

def list_cameras(max_devices=5):
    available = []
    for i in range(max_devices):
        cap = cv2.VideoCapture(i)
        if cap.isOpened():
            available.append(i)
            cap.release()
    return available

print(f"Available cameras: {list_cameras()}")

camera_index = 1
cap = cv2.VideoCapture(camera_index)

Using on Jetson

v4l2-ctl --list-devices
gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! autovideosink

FAQ

Q: Camera not detected?

A: Ensure the USB cable is firmly connected. Try a different USB port. Run lsusb to check USB device list.

Q: Blurry image?

A: The camera has auto-focus — wait 2-3 seconds after first connection. If still blurry, clean the lens surface.

Q: How to change resolution?

A: Use cap.set(cv2.CAP_PROP_FRAME_WIDTH, width) and cap.set(cv2.CAP_PROP_FRAME_HEIGHT, height).
