On the host side, you should have a PictureBox control for the frames to be drawn on, and declare the TCPHost object (as a global variable): Use this if you want to have some more control - like sending your own images, and choosing the PictureBox you want the frames to be drawn on.Įxtract the " TCPCam.zip" file attached, and you should find this directory: " TCPCam\TCPCam\bin\Release". You can handle these events to monitor your connection status and draw on the camera frames with GDI. Every time a client disconnects, the LostConnection event is raised. The OnConnection and LostConnection events are only fired on the host side every time a client is connected, the OnConnection event is raised. Every time a connection ends, the control raises the Disconnected event. The Connected and Disconnected events are only fired on the client side every time a connection is successfully made, the control raises the Connected event. The OnFrameDraw event comes with the e as PaintEventArgs argument, which allows you to draw directly on the frame, and can be used on both sides. This ActiveX comes with the following events: Webcam.StopCamera() ' Stops the camera capture ActiveX Events Webcam.Disconnect() ' Disconnects any open connection On the host side application, we should start listening to any incoming connection, so we would use this method on the Form_Load event handler: I called the ActiveX the same name on both the client and host applications - " Webcam". Now just drag the TCPClientActivex control to your form this is where your camera frames are shown.Go to the extracted directory path I mentioned earlier and import this file: TCPCamActivex.dll.Enter the ".NET Framework Components" tab, and click on "Browse.".Click "Choose items." and a dialog should pop up.Open the Toolbox and right click on an empty space in the toolbox.Use this if you want to stream your video in just a few short steps, no need for a lot of programming - drag and drop the control and write a little code.Įxtract the " TCPCam.zip" attached, and you should find this directory: " TCPCamActivex\TCPCamActivex\bin\Release". The main concept of this library is that the client that is connected to the image source (camera) sends the frames to the host (serializes the frame and then sends it) the host deserializes the image and updates the PictureBox/control. As two classes client and host, including some advanced methods for advanced users.As an ActiveX (a control) which allows you to drag and drop it to your form like any other control - including the host and the client method in the same control.I separated this library to into two different ways of usage: This library includes the camera capture class and the camera stream class. In this project, I modified the ICam to fit my needs. I used the ICam class developed by Pino to capture the camera frames you can find the original ICam class here: ( check out his site). The camera stream should work well without any noticeable delays on your Local Area Network, but will lag when using it with an internet connection. NET Framework.Īlthough this article is written in VB.NET - you can use it with your C# projects too! This library allows you stream your camera video to another application written using the. I myself needed it for my school project - but I couldn't find any free working library on the web, so I did some research and connected all of the different pieces to create this library. I have seen a lot of people searching for a library capable of streaming a live camera video between two applications through the LAN or any other kind of network. Download BertManRecordableTCPCam.zip - 346.11 KB.If I'm recalling correctly, one nice solution. though that probably wouldn't be an issue for your use case (is for mine) OBS can use RTSP, though I've read about latency issues. someone else will correct me if I'm wrong, but many of the IP security cameras support ONVIF, a common real time streaming protocol (RTSP). look for 30fps at the resolution you desire (and is that 720p. you realize a key ingredient to look for is the resolution and frames per second (I'd avoid the many devices that only do 15 fps). I found one YouTuber that does reviews of IP security cameras, with an eye towards security, not streaming, but important to this discussion is he does a video quality test as pixel count can be misleading, at best. but its expensive, and I'd like some alternate perspectives (camera angles) and am not in a position to buy more Panasonic (or similar Tier 1) NDI PTZ cameras at this time. I have a nice Panasonic AW-HN38 NDI PTZ camera.
