Are you able to use existing IP cameras instead of setting up pi’s for the Jetson TX2 setup? If so where do you specify the IP addresses of the cameras?

here?

url1='http://pi1.local:8000/stream.mjpg'
url2='http://pi2.local:8000/stream.mjpg'
url3='http://pi3.local:8000/stream.mjpg'
url4='http://pi4.local:8000/stream.mjpg'

Hi @vondalej

Yes, please specify the IP addresses of the cameras here. Any IP camera can be used not just raspberry pi.

Hi there, Enjoying this project, greatly appreciate it, however I am stuck on an issue currently and wondering if you could offer any guidance

File “jetsonano/securitycamnano.py”, line 77, in
fgmask=cv2.erode(fgmask,kernel,iterations=1)
cv2.error: OpenCV(4.5.1) /tmp/pip-req-build-zuuo394f/opencv/modules/imgproc/src/morph.dispatch.cpp:1010: error: (-215:Assertion failed) !src.empty() in function ‘erode’

I am using a Jetson Nano . Thanks

Hi @nemesjs5662 which camera are you using? This error means that opencv is unable to read frames from your camera. If you are using a USB camera, this will not work and you will have to do some small modifications.

Hi sir, I have a Aluratek HD 1080P Video Webcam
Yes i realized your gstreamer pipeline wouldnt work with my camera and modified that already

however this fixed the pipeline error and brought me to the error in my earlier post around erode plus these warnings .

What else do i need to modify to ensure usb camera will work. Thanks so much

I modified the config.py for usb camera true and was able to get it to run but it never recognized a person in the frame.

If you can offer any insight i would greatly appreciate the help. Thanks!

@nemesjs5662 Great that it worked out for you. You can run the Jetson Nano in 2 modes: as jetson nano, in which case it will do motion detection in real time but not object detection. You can also run the jetsontx2 scripts on the nano which will detect objects from up to 4 cameras and display them on the screen.
