I have a IP camera in homenetwork. I can control it by web access. I want to send a request from arduino program (in the same homenetwork) that will control ptz of camera. How can I find the link - part of script ... to turn camera on preset position? Arduino + ethernet schield is controled from web server out of my homenetwork and I want to use it to control ptz of camera.
we are doing a project on image processing using a camera,raspberry pi3 and a gsm module. Above mentioned things are with a flying drone. I can send a notification message to a mobile using gsm module if required object detected on the cam. But we store that image to view on a webpage or through a mobile app easily. while it's flying it can't connect to the internet. So can you suggest a solution to get those images when it is inside our home wifi range.(any how we can get the images from sd card but i need to get those as soon as possible it detected the wifi) . Thanks in advance
You could consider using "tethering", a.k.a. "Personal Hotspot" in Apple parlance, on your mobile phone.
Basically, you would enable the Personal Hotspot on your iPhone and allow your RPi to connect to it via Wifi. You would have to check your setup, but my iPhone takes IP address 172.20.10.1 for itself and dishes out IP addresses to clients which are the same but with the 1 replaced by a small number under 13.
You can see from here how to setup your RPi to automagically connect to your Hotspot whenever in range. You could also consider fixing a static IP address when on that network, so you know where the RPi will show up for sure.
You would then ensure that Apache, or maybe lighttpd which is lighter weight, is running on your RPi.
Then, your app on the RPi would store its image as image.jpg in Apache's DOCUMENT_ROOT directory, probably /var/www/html/image.jpg but check.
Now, on the iPhone, start Safari and browse to:
http://172.20.10.N/image.jpg
where N is a small number. You should see your image and be able to save it to DropBox or Photos or iCloud Drive for others to see.
Of course, once your RPi is connected to your iPhone's hotspot, it can FTP or ssh copy the image to any website or other server on the Internet it has access to itself.
I have understood your question also I have cheapest solution to build your project. you will be needing 3 modules
ESP8266 (Wifi module)
SD card logger
Camera module(go with your choice, try ESP8266(But I have not tried it))
Combining all these can get your work done. But most instructing part is When connected with wifi it should transmit video to webpage or app and when not connected should log video to SD card
Below is my try to solve your problem, if you have any doubts feel free to ask your question.
ESP8266 is an WiFi module, you can connect it with an hot-spot or an router, similar to any WiFi device's on successful connection it throws 200,OK failing will throw 404 or so. Technically just like any TCP devices it will work. You can connect, disconnect, send and receive data continuously using software(using code you write).
0-code for camera unit starts
1-try connecting WiFi && start the camera and start logging into SD card //InCase if WiFi module takes longer time than usual to connect, this will prevent data from losing
2-if connection failed - continue writing to SD card
3-else(connection made) - start streaming the data && stop the SD card logging and save the file and create a new empty file so that we can save on next connection out without wasting data.
4-check for connection status in regular interval (goto step2).
5-on any external inputs(like click an image)
most important thing: code for your camera interface should work independent from the flight controller code.

Just for reference the Sony Remote Camera API only works by using a 1:1 Wifi Connection
The Wifi signal strength of my Sony DSC-HX60V camera already drops after a few meters distance. But I want to be able to remotely control the camera over a range of 50 meter. There is no way that the onboard Wifi can achieve this range.
So now Iam looking for a solution to this problem. If it helps a local Wifi router exists that covers the whole range:
A normal Wifi repeater seems to be the best option, but according to a Forum Post using a repeater does not work, because the repeater acts a client and the camera can only connect to one client at the same time. Did someone got it to work with a repeater?
Additionaly I was thinking about using a Raspberry Pi with a second Wifi adapter that connect to the local Wifi and manages the API requests.
Any other ideas?
Disclaimer:
Even tho this Question may be more Hardware and Network related and thereby fits more into the SuperUser Network. A working Network connection does not necessary imply that the API is working aswell. This is why I posted this Question here
If you have a router which can work in 'client mode' that should be able to make a 1:1 connection with the camera, and then present that link over ethernet - you may have issues with network addresses and/or discovery if your main network is a different IP range to what the camera offers/DHCP's.
Some of the Sony cameras support 'multi-wifi' where the camera connects to an external device (normally the LiveViewRemote, but can be a router). Unfortunately the HX60 (and presumably any of the Play Memories SmartRemote app based ones) does not seem capable of this.... maybe the QX1 is an exception as it's supposed to work like this.
This connection connection is managed via WPS, and once connected the RemoteAPI works well. Works for my AS100.
If you are looking to set up a RaspPi, I can confirm that it works with this Python library:

I'm streaming raspberry pi's pi camera over pi's local ip address with specific port. (eg: 192.168.1.111:8000/stream.mjpeg)
I can see the stream over xamarin.forms webview but I want to display it on Xamarin.Forms app with local media players for both iOs and android. Thus I can add control buttons for camera under the videoview. since it is live streaming I dont need forwards or backwards button functionallity.
I definitely lookup at least 5 pages per google search for all the keywords I have but there is nothing I find useful.
Any clues, starting points are appreciated too.
all,
I wanted to do a capture and encoding of camera modules, and made in the form uvc device, now I have a development board can capture and encoding, If I implementing the board to act as a UVC device, when used otg or usb connection the development board, you can see the image acquisition.
