To access an Ip Camera  first  I recommend you to install it like you are going to use for the standard application  without any code  using normal software    After this  you have to know that for different cameras  we have different codes  There is a website where you can see what code you can use to access them   https   www ispyconnect com sources aspx  But be careful  for my camera  Intelbras S3020  it does not work  The right way is to ask the company of your camera  and if they are a good company they will provide it   When you know your code just add it like   cap   cv2 VideoCapture  http   LOGIN PASSWORD IP cgi-bin mjpg video cgi  amp subtype 1     Instead LOGIN you will put your login  and instead PASSWORD you will put your password   To find out camera s IP address there is many softwares that you can download and provide the Ip address to you  I use the software from Intelbras  but I also recommend EseeCloud because they work for almost all cameras that I ve bought   https   eseecloud software informer com 1 2   In this example  it shows the protocol http to access the Ip camera  but you can also use rstp  it depends on the camera  as I said    If you have any further questions just let me know

An IP camera can be accessed in opencv by providing the streaming URL of the camera in the constructor of cv2 VideoCapture   Usually  RTSP or HTTP protocol is used by the camera to stream video  An example of IP camera streaming URL is as follows      rtsp   192 168 1 64 1   It can be opened with OpenCV like this   capture   cv2 VideoCapture  rtsp   192 168 1 64 1     Most of the IP cameras have a username and password to access the video  In such case  the credentials have to be provided in the streaming URL as follows   capture   cv2 VideoCapture  rtsp   username password 192 168 1 64 1

The easiest way to stream video via IP Camera    I just edit your example  You must replace your IP and add  video on your link  And go ahead with your project   import cv2  cap   cv2 VideoCapture  http   192 168 18 37 8090 video    while True       ret  frame   cap read       cv2 imshow  frame  frame      if cv2 waitKey 1   amp  0xFF    ord  q            cv2 destroyAllWindows           break

As mentioned above by  Gustavo GeoDrones you can find your Cam URL using https   www ispyconnect com sources aspx  Go to the website  click on the model of your camera and a  quot Cam Video URL Generator quot  will appear  Insert your IP  username  etc  and click on  quot generate quot   Cam URL for my Canon VB-H45 is  of course with my specific username  password and IP   http   username password IP -wvhttp-01- video cgi  The final code  cap   cv2 VideoCapture  http   username password IP -wvhttp-01- video cgi

I answer my own question reporting what therefore seems to be the most comprehensive overall procedure to Access IP Camera in Python OpenCV    Given an IP camera    Find your camera IP address  Find the port where the IP address is accessed  Find the protocol  HTTP RTSP etc   specified by the camera provider    Then  if your camera is protected go ahead and find out     your username  your password    Then use your data to run the following script      Access IP Camera in Python OpenCV     import cv2  stream   cv2 VideoCapture  protocol   IP port 1      Use the next line if your camera has a username and password   stream   cv2 VideoCapture  protocol   username password IP port 1      while True       r  f   stream read       cv2 imshow  IP Camera stream  f       if cv2 waitKey 1   amp  0xFF    ord  q            break  cv2 destroyAllWindows     NOTE  In my original question I specify to being working with Teledyne Dalsa Genie Nano XL Camera  Unfortunately for this kind of cameras this normal way of accessing the IP Camera video stream does not work and the Sapera SDK must be employed in order to grab frames from the device

First find out your IP camera s streaming url  like whether it s RTSP HTTP etc   Code changes will be as follows   cap   cv2 VideoCapture  ipcam streaming url     For example   cap   cv2 VideoCapture  http   192 168 18 37 8090 test mjpeg

Getting the correct URL for your camera seems to be the actual challenge  I m putting my working URL here  it might help someone  The camera is EZVIZ C1C with exact model cs-c1c-d0-1d2wf  The working URL is  rtsp   admin SZGBZT 192 168 1 2 h264 stream   where SZGBZT is the verification code found at the bottom of the camera  admin is always admin regardless of any settings or users you have   The final code will be   video capture   cv2 VideoCapture  rtsp   admin SZGBZT 192 168 1 2 h264 stream
