While the AWS DeepLens camera<\/a> is designed to work with AWS, it’s just a normal linux camera and you can open video streams from OpenCV.<\/p>\n

The camera comes with a firewall (UFW) pre-installed, so you need to disable a port for video:<\/p>\n

sudo ufw allow 8090\n<\/pre>\n
Then edit the ffserver configuration file to expose the streams from the camera:<\/p>\n
sudo vi \/etc\/ffserver.conf\n<\/pre>\n
Add the following:<\/p>\n
\n\n  File \"\/opt\/awscam\/out\/ch2_out.mjpeg\"\n  NoAudio\n<\/stream>\n\n\n  File \"\/opt\/awscam\/out\/ch1_out.h264\"\n  NoAudio\n<\/stream>\n<\/pre>\n
Then run ffserver.<\/p>\n
Now you can access this remotely with Python:<\/p>\n
import cv2\nimport datetime\n\ncamera = cv2.VideoCapture('http:\/\/192.168.1.187:8090\/feed.h264')\nwhile True:\n  (grabbed, frame) = camera.read()\n\n  if not grabbed:\n    break\n \n  frame = cv2.resize(frame, (int(1920\/4), int(1080\/4)), cv2.INTER_AREA)\n\n  cv2.putText(frame, datetime.datetime.now().strftime(\"%A %d %B %Y %I:%M:%S%p\"),\n    (10, frame.shape[0] - 10), cv2.FONT_HERSHEY_SIMPLEX, 0.35, (0, 0, 255), 1)\n\n  cv2.imshow(\"Feed\", frame)\n\n  key = cv2.waitKey(1) & 0xFF\n\n  if key == ord(\"q\"):\n    break\n\ncamera.release()\ncv2.destroyAllWindows()\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
