scan for IP Cameras
-
Hello experts, imagine a 1000MBit/s network. Say it's just one NIC and a camera wit one cable in between. When plugged in for the first time, the two devices are not necessarily set up to operate in the same subnetwork. Nevertheless you can set an option in the software delivered with the camera that says "Ignore Subnet" and then let your computer detect the camera. You can then change the camera's ip/subnet settings to fit your desired network and use it. The camera is some Dalsa Genie model supporting GigEVision and Gen_Cam standards. Does anyone know how I could achieve the above described behaviour in my own software? Ciao, luker_

Sounds a little specialised, I dunno if there are many people that can help you with that.

I try to give an answer, from your description I don't understand what you want to do. Is it about automatic network configuration of a device (e.g. DHCP?) or detecting hardware presence in LAN (e.g. UDP broadcast). I suggest to download Wireshark and record the network traffic, then you should be able to mirror the functionality or get some further ideas where to look at. Hope this helps! :) /Moak

I am working on a similar problem at the moment and although it is not an IP camera I suspect that the principles are likely to be the same. The device I am working with has a configuration tool that operates in the same way that you describe. I used Microsoft's Network Monitor, although Wireshark would do just as well, to see how it discovered the device on the network. What I learned from the network trace is that the application sends out a subnet broadcast to a UDP port which the device then responds to. From the response the application then knows the IP address of the device and the initiates a point-to-point TCP connection to configure the device. I am still deciphering the UDP payload the application sends and the response the unit sends but I hope that helps.
