Hi everyone,
After they broke in by my mother and a few weeks later by my sister at home ...
I decided to install some IP cameras and to connect them to a PC running win,
internal camera via wifi, and two external cameras via LAN (CAT5) cables.
this two cameras are connected to a HUB and PC.
Is there a way to create a IP connection via PB 5.70, and view in a real time steaming window,
and store the images on a HDD ?
thanks,
marc

How large is your HDD ?
If you only want to store the stream it should be no problem.
But I think it is enough to fetch every 5 second a picture and store it.
In this way you can also show the pictures directly in PB.
For the stream you need to embed/involve VLC or ffmpg.
But you will get a lot of traffic on the net.
In our company we installed a complete own network infrastructure for the cams,
because else they slow down the normal user network.

Hi marc_256,
I know you're familar with
PureBasic Interface to OpenCV, but have you tried connecting your camera via OpenCV's RTSP, particularlly using the FFMPEG functions; see the example
cv_RTSP_writeframe_FFMPEG.pb. Combine this with the example
cv_webcam_zone_tracking.pb, could make for a powerful application.
Another option might be to use the WebGadget, capturing the RTSP stream, drawing its contents to an image. Depending on the cameras manufacture, it should come with a configuration tool built-in to the firmware.
Cheers!

Hi infratec,
I will also extend in my company the existing alarm system with some cameras,
and I bought a exterior HDD of 2 x 2TB in RAID 1 mode.
With a separated LAN for the cameras.
And you are write every 5 sec is OK to send via WIFI,
and streaming only if there is an alarm.
Yes, I was looking to VLC ...
Hello JHPJHP,
"I know you're familar with PureBasic Interface to OpenCV"
I think you are the best man who is familar with OpenCV
Oh, yes I will see for it,
I like to use PB so I can control some stuff myself.
I gone work on it this WE ...
thanks for the tip.
greetings,
marc
