I would please like to know if it is possible to retrieve images from a Sony Camera when it is connected to a Wifi Access Point on our local network? I want to retrieve the images from the camera with C# code.
Can anyone point me to where I can find resources regarding this?
Depends on what Sony Camera you are using. See the Camera Remote API SDK page for more details on the API. Inside the SDK you will find a PDF with a list of which APIs are supported for which cameras.
https://developer.sony.com/develop/cameras/
Also, the Camera itself must act as the WiFi access point and you connect to it with the host device that you want to use to control it.
It is possible but there are no public resources regarding it. See my answer to a related question here.
Quoting myself (there's more detail at the link) - this is based on the Sony A7:
The camera has 2 Wifi-connection modes:
(a) AP-mode ("Connect to smartphone"), where the camera acts as an AP you can connect to. Only gives access to JPGs, not raws. API is proprietary but public (https://developer.sony.com/develop/cameras/)
(b) Infrastructure mode ("Connect to computer"), where the camera connects to an AP and pushes any files to a computer on the local network. Uses some MTP-flavour (based on PTP/IP).
So for (b) you would have to use or implement some kind of MTP- or PTP/IP-stack. You would also have to know the MAC-address of the computer the camera has been "paired" with previously.

In my project, ı need to write a program that can access an external soundcard and take discrete input sound data. The device uses isochronous data transfer and Usbccgp.sys driver. In that case, I can not use WinUsb and LibUsb functions. What should be my solution path in that situation? Writing a new driver to access the device or using another driver to communicate each interface of the device?
Your sound card probably already has drivers, assuming it is a real product made by a company who wants its users to actually be able to use it. So you don't need to write drivers.
Just use the appropriate Windows sound API. I'm not sure which one is the best, but here are some links to start off your research:

I can see that Sony made an application named Remote Camera Control that controls a Sony camera over USB. Is there somewhere where I can find maybe the API or SDK to communicate with this camera like the Remote Camera Control does?
There is a lot of ressources on Developer Sony website
Unfortunately, Remote control over USB is not possible using public API. This might be modified in a soon futur by Sony but for the moment you have to give a look to unofficial library like this Github projet which try to provide such control (but is 6 years old and has not been updated since).
This post on stackoverflow refer to "the PTP protocol for libgphoto" which seems an option ... I don't know much about that.
What about Sony Remote camera control which might provide some API ... worst case you can have some code to simulate a click (like a robot) but thats a terrible option :D
I'm working on an application that is joining two projects in two different courses in my Software Engineering degree:
SWE 490: Component Based Software Engineering
SWE 344: IP and Client Server programing
Here's what's my application about :
Client Side (Desktop Based): Main function is to capture the webcam video and stream it to the server.
Server Side (Web Based): Main function is to receive the streamed video from the client and display it on the website in real time.
Brief Description of the application :
The users will be able to monitor their Webcams remotely by streaming their webcams output to a remote server that is accessible via the web. The system will also serve as a motion detection system (if activated by the user) to notify the users via email if any motion has been detected on their webcams. In addition the system also allows users to schedule recordings and watch them online through live streaming.
I'm preparing a proposal for the project and I've made some initial plans for the system structure that is represented below :
Client Side Components (Desktop) :
Server Side Components (Web Server) :
My Question :
My main issues are with the real time video streaming (sending and receiving components) as this is a new topic for me.
I know I can program a socket and send the captured videos as a stream of bytes to the main server, but what I'm concerned about is how am i going to display the received stream on the web browser at the server side.
My situation is similar to this question except that it's for video streaming and not image streaming.
I've been reading some articles and it seems like it can be done using Silverlight and I'm hoping someone can point me to the right direction.
Your opinions on the project in general are more than welcomed.
I know it's in VB.Net, but this article may be a useful reference guide.
P.s. you misspelled Quartz in your diagram ;)
I agree that Silverlight should probably be your first stop.

Okay so this is obviously no longer valid, you can stop down voting it already ...
I'd like to know if it is possible how to do it, because my client asked me if the program I'm developing could also send wallpapers to nearby cellphones(my program will be in a place with many people passing by, so it would be good to have the bluetooth feature).
Thanks!
it can send pictures as files, users then may set them as wallpapers.
Unless the phone and the computer support bluetooth and are connected, you cannot. You can send the files to mobiles over bluetooth. 32feet provides a nice library to perform bluetooh related operations. Try that.
Hope it helps.
To do this you would need to
Make sure each user's device is paired to your bluetooth "sever"
Create the ability to auto connect and send the file.
On your phone's application, receive the image file and set the phone background - this will be different for each type of phone's OS. I would assume you are aiming towards Window Mobile Devices, since you are using c#.
The first step i see as being the difficult step as each phone much "register" the bluetooth of the server to be paired with it.
I want to write an application that can capture from a TCP/IP camera. I haven't bought the camera yet. I have the following questions:
What should I look for in the camera?
Do all cameras have SDKs or APIs for that?
thanks
Most cameras produce a JPEG or MPEG4 stream, or both, that you can capture. My cameras do not let you download images, unlike Earwicker claims. They can, however, send images by email, ftp, or write them to an SD card.
I use the software on my Synology Rackstation to record streams on the NAS. I have not really looked at the software that they use, but I am almost certain that, behind the scenes, it is some Linux software that is freely available. You could look into that.
Get a camera that has an HTTP server, allowing you to download images from it like any web server. This is standard on most IP cameras.
