# Configure camera buffer
camera = client.add_camera(
    name="Store Front Entrance",
    rtsp_url="rtsp://192.168.1.100:554/stream",
    retention_hours=72,
    resolution="1080p",
    bitrate_mbps=2.5
)

# Later: Review incident
incident_time = datetime(2026, 2, 22, 14, 30)
clip = camera.export_clip(
    start_time=incident_time - timedelta(minutes=5),
    end_time=incident_time + timedelta(minutes=5),
    format="mp4"
)

print(f"Clip saved: {clip.download_url}")
