Software (API/DLL) to command the show of video from various camera on control screen
 

Hi all,

I have an application attached with 3 cameras that record video at different location but linked to the same processor or video server that is connected to a wireless router via TCP/IP.

I wish to view only one video from a camera at one time. I would like to have a software that enable me to select which camera video I would like to show at one time on my control screen for the application. I may switch to other video from other camera at any time.

Does anyone has idea where I can find this API/DLL?
I have been trying to look for it for two days but I come out with nothing.

Thank you in advance.

There is about 245 different ways cameras connect and work.

It may not be possible to know unless you tell us more about product model and how it connects and what os and well, you get the idea.
