I was doing research and couldn't get myself in the right direction so I figured I would ask if it's possible.
For my desktop computer I dont have a mic or a webcam but needed it for some applications.
So I thought to create an app for my Flame that when connected over USB will act as mic and webcam. Is this possible?
Yes you could use webRTC to connect PC & phone and share webcam/mic (either phone->PC or PC->phone). Try Firefox Hello if you want to see how webRTC works.
For example, try http://mozilla.github.io/webrtc-landing/ in both your device and desktop

I am sorry, this might not be the correct platform to ask this kind of question but I couldn't think of any other place .
I for one of my project I need to capture some video footage from an outdoor camera using open cv. Actually, its a part of a bigger project where another signal triggers the camera. Since the camera will be located outside, I am looking for weather proof night vision enabled USB cameras that I can easily control via OPENCV. However I cannot find any descent USB camera and most of the websites show IP cameras. My problem is that the installation will be at a site where there is no internet so I cannot use internet. Can anybody please suggest if and how these IP cameras can be connected to the PC and be controlled via OPEN CV or else suggest some websites where I can get descent outdoor USB IR cameras.
I have also tried the NOIR Raspi camera but the quality is not very good and I think the range will also not be very good. Moreover running OPEN CV on RpI is very slow even for simple video recording.
Please refer to that thread for how to use IP cameras with open CV. I didn't try it personally, but a simple google search got me that. http://answers.opencv.org/question/133/how-do-i-access-an-ip-camera/
To access an IP camera is very simple, you just need this line:
cv2.VideoCapture("rstp://ipaddress:port/blahbla")
Now, if you dont have internet the IP camera as the PI should be on the same network, you can have a wireless router with no internet.
If you dont have a wireless router you can create a hotspot on your PI so you can connect the Camera directly to the PI, alot of IP cameras support hotspot so you can connect your pi to them.
I'm currently studying the Development Guide given with the Sony Camera Remote API beta SDK, and what I've understood so far, is that in order to send and receive messages between a camera and a mobile device, the smartphone or tablet should be connected through Wifi to the camera, which acts as an access point.
Actually, what I'd like to do after downloading a picture on the mobile device from the camera, is to pass it to a PC so that I will be able to print it and use it for other purposes. This process should be completely transparent and automatic for the final user.
Thus, my problem is that I need the mobile device to be connected, through Wifi, to both camera and PC.
The solutions I have in mind are :
Make the mobile device, and the PC, connect to the camera access point, so that they can be located on the same network.
Is this possible? I mean, can the Sony camera handle more than one client when acting as an access point? If yes, can I have a fixed IP for mobile device and PC so that I can easily make them exchange data?
Use a simple wifi router and make the camera, mobile device, and PC connect to this router.
Without acting as an access point (i.e. simple network client), can the camera be used with the remote control function?
If you guys see any other options, I'd be glad to read them !
Thanks,
Bertrand
Unfortunately, neither of your solutions would be supported. Only one device can be connected to the camera AP at a time, and the camera itself has to act as the access point (certain models support connecting to an access point from the camera but the Camera Remote API is not supported in this case).
If you don't need the mobile device to have access to the pictures, your best bet may be to directly connect the PC to the Camera and transfer the images using the API. The API is REST based so can be used on any platform.
I have a Sony HDR-AZ1 with the RM-LVR2V remote.
I'm currently integrating the Remote API into an Android app that we are developing. The app will download video and photos from the camera, and transfer them to our web service.
What I've discovered is that it appear as if only one device can be connected to the camera at any single time - either my smartphone or my RM-LVR2V remote. Not both at once, which I would need. I'm not sure if this is the case, but it appear as if I have my smartphone connected to the camera, then I cannot connect my remote, and vice versa. Is this correct?
Is there some way to connect both my RM-LVR2V and my smartphone to the camera, at the same time?
Unfortunately connecting both at once is not possible. The Camera only supports one WiFi connection at a time. You may want to look into using something like a SmartWatch 2 or 3 to connect to the phone and then the phone to the camera to achieve what you are trying to do.
This is technical question to check the possibilities of the scenario. Is it possible to use Nokia phone's (Lumia, N9, symbain phone, S40) 3G data connection with a Android tablet pc?
Or any way to use phone's 3G data connection with tablet pc?
I have a unlimited data connection for my phone. But I don't use it that much. So I'm planning to use it with the tablet pc.
yep its possible easily if :
1. your tab is rooted
2. your tab supports usb host mode or otg mode (you could either check it on net or download usb host diagnostics) (just click start diagnostic)
procedure
Downoad ppp widget
configure your apn according to pc suite settings
then plug in your phone via usb on nokia pc suite mode
now wait 10s and click connect
you are now done
(pls switch your wifi off as ppp widget creates virual wifi for your tab)
any inquiries contsct rld0989#gmail.com (don't be rest less I only check my gmail once a day)
Yes, it's possible to use your phone as a modem, connected to the tablet via a USB cable, as long as you have
(1) an APN from your network operator to make a data connection via their network, and
(2) suitable device drivers for the phone. On Windows, smartphones are plug and play, but I don't have any experience using them with Android.
On the tablet, you also need some software to control the modem - something like the Mobile Broadband Connect 3.0 application listed on here
You can write a simple connection app yourself using the Android Telephony Manager.
Alternatively, you could connect manually, using AT commands with a suitable AT command program (in Windows, it would be Hyperterminal). This thread describes a possible equivalent for Android.
Standard AT commands to make a data connection are described in the 3gpp TS27.007 specification.
There are a lot of variations for different manufacturers, but making a simple connect should be possible using the standard commands.
If I connected a Symbian cellphone to PC via usb, is there any way to remotely and programmatically read IMEI.
Nokia Ovi Suite can read it but I didn't see any public APIs.
In most simple Nokia phones you can do this by sending AT+CGSN\r\n on the serial port of the modem of the phone. However if I remember well on smartphones Nokia disabled this feature for some reason. Anyhow it worth a try. Here's a nice tutorial on how to do this: http://www.developer.nokia.com/Community/Wiki/AT_Commands
