I'm trying to find an IP camera that allows me to operate it via UPnP. The UPnP forum provides a Digital Security Camera profile:
http://upnp.org/specs/ha/digitalsecuritycamera/
However, I have not been able to find an IP camera that implements this profile, which would allow a uniform method of controlling different IP cameras. Most IP cameras appear to implement UPnP for discovery purposes only, with the user having to retrieve the presentation URL for the device and then control the camera via the manufacturer's web UI.
The UPnP forum list of certified products does not contain any such devices, and the websites of most IP camera manufacturers are vague about what UPnP services they provide (if not explicitly stating that they only support device discovery).
Has anyone come across any IP cameras which support the Digital Security Camera profile and it's associated services?
I know this is an old question, but I came across it in a search and thought I'd share what I know.
I own two D-Link DCS-5010L cameras. The documentation for the camera doesn't specify specifically which UPnP services the camera supports. Here's a link to the User's Manual:
http://www.dlink.com/-/media/Consumer_Products/DCS/DCS%205010L/Manual/DCS_5010L_A1_Manual_v1_00_WW.pdf
On page 47 it says it supports "UPnP Port Forwarding". UPnP only appears six times in the User's Guide.
I can tell you that it supports email of images of video, pan / tilt, and video sharing. Sorry, I know that's pretty general information, and it seemed like you were looking for some specific answers. I googled it and searched around, I couldn't find anything listing the specific UPnP services supported. My guess is, you might need to contact the different camera vendors. It might give you a good start, if you're still looking for the info four years after you posted the question. :-)

I'm new to UPnP development and recently started to use Cling to develop a UPnP client in Java.
To me the Cling documentation is insufficient. Especially it's lacking of basic examples, such as discovering UPnP devices via IP address.
The search for all available devices is shown in an example:
UpnpService upnpService = new UpnpServiceImpl();
upnpService.getControlPoint().search(new STAllHeader());
However, this search is very slow compared to other UPnP applications, such as my remote TV control app on Android.
This leads me to three questions:
Can you point at good tutorials, that show how to use Cling to remote control TVs?
Is there a way to speed this search up? Or is there an alternative type of search that achieves the same results in less time?
How can I search for a device via its IP address directly?
I'm trying to create a virtual classroom. Since I'm not familiar with the web conferencing (or conferencing) terminology, I'm not sure if I'm understanding WebRTC's capabilities as I should.
I've looked in the examples for WebRTC, and all that I've found seem to be peer-to-peer connections. As I understand it, peer-to-peer connections are between two entities. However, virtual classrooms are different as far as I know; they require all parties to be connected to each other, so that when one user speaks/types, all users hear her.
Is such a thing possible with WebRTC? If so, what is it called and how can I read more about it?
Check out the open source Big Blue Button project (http://bigbluebutton.org/). They're currently Flash based but are actively moving towards webRTC. Rumor has it they'll be using Kurento as their MCU. They also have open source mobile (Android/iOS) application code.
According to http://www.html5rocks.com/en/tutorials/webrtc/infrastructure/, such a thing is possible:
Beyond one-to-one: multi-party WebRTC
You may also want to take a look at Justin Uberti's proposed IETF standard for
a REST API for access to TURN Services.
It's easy to imagine use cases for media streaming that go beyond a simple
one-to-one call: for example, video conferencing between a group of colleagues,
or a public event with one speaker and hundreds (or millions) of viewers.
A WebRTC app can use multiple RTCPeerConnections so to that every endpoint
connects to every other endpoint in a mesh configuration. This is the approach
taken by apps such as talky.io, and works remarkably well for a small handful
of peers. Beyond that, processing and bandwidth consumption becomes excessive,
especially for mobile clients.
Maybe you can try searching in the webrtc google group
hope this helps
Can we control multiple DSC-QX100 cameras using the Camera Remote API SDK from an iPad OS7?
The objective is to cause multiple cameras to "snap" picture at the exact same time. Perhaps each camera has an address (serial number)...can the software communicate with all cameras at the same time using multiple addresses? Need is limited to still photos and so-called fast, rapid photography. Video not necessary.
If so, how?
Unfortunately you can only control one QX100 lens at a time. This is because the lens connects over WiFi and you are limited to only a single WiFi connection at once on an iPad. It may be possible using a desktop PC with multiple wireless cards installed but that would be the only way.
As the Sony rep said, there's no way to do this with "officially supported" techniques.
The reason for this is that the camera acts as a WiFi Access Point (AP) - so while multiple devices can connect to it, most mobile devices can only connect to it and not anything else (since iOS and Android don't support connection to multiple APs simultaneously). This is also why you can't use other network interfaces when connected to the camera. (I don't know about iOS, but Android always prioritizes WiFi over cell network data, for example.)
Android devices have a feature called "WiFi Direct" that provides more flexibility in terms of peer-to-peer interconnection, but iOS does not support WFD. The QX100 DOES respond to WFD invites, and you can accept a pairing request with (if I remember correctly) a long-press of the shutter button. However, the official app only supports normal WiFi AP connections.
I have not yet attempted to see if using Sony's remote API in combination with the (unsupported but apparently present) WiFi Direct capability works.
More info on Wifi Direct and Android can be found at http://developer.android.com/guide/topics/connectivity/wifip2p.html
Marlin SONY, I disagree, wifi is Ethernet and by definition can handle multiple devices on the same network. If you run a phone or iPad as a hotspot and connect multiple devices, it works.
Multicam Switcher Basic is an example of a free app that supports cutting together multiple camera angles live. Unfortunately the app is still being developed so features like third party camera support isn't included, but it does show what is possible and awaits development.
I think this should be possible. Apps like CollabraCam™ (Multicam Social Video Production) or RecoLive MultiCam prove that is possible to use mulitple cams simultaneous.
I need someone too to develop an App to be able to use "two" sony dsc-qx for 3D shoots. Please, if You know how or who can do this contact me email#3-d.re
I searched about this on google but could not find any suitable answer so posting here for help.
I want to implement video streaming with multiple participants connected. While google this topic I found that WebRTC provide similar functionality but I want to make sure whether WebRTC can support all my requirements.
I want to build an application that should support large number of participants in conference (around 10000).
I want to implement facility like one participant is broadcasting its video and audio streams and other are just listening to their stream.
Also when prompted only one participant will be able to communicate with broadcaster which will be managed by one participant (a administrator). Administrator will decide who can communicate with broadcaster.
Is same can be possible with any other WebAPI ?? I found OpenTok, but not confident if it provide any feature of moderation in conference (i.e. feature of having an Administrator who manages stuff)
Did anybody worked on similar concept or having any information related to this.
Let me know if I am not clear of any further details are required.
Any help would be useful,
Thanks in anticipation
Hardik - I am Product Manager at TokBox, the makers of the OpenTok platform. Good news: TokBox can fulfill virtually all of your requirements, but with a few caveats.
TokBox has been building a video chat/conferencing platform for years, long before WebRTC even existed in fact. In that time we have supported many customers with almost your exact requirements on OpenTok, a platform that is based on Flash (Major League Baseball is one such customer). Building applications on this architecture has the added advantage of solving virtually all of the interop issues that exist when connecting people using different devices and browsers. It is based on Flash however, which technically doesn't meet your WebRTC requirement. So you know, there's that.
WebRTC is where it's at though, which is why we created OpenTok for WebRTC in 2012. It was a complete rewrite of the platform that not only provides higher quality video, but also gives developers more hooks and far more control over how exactly they integrate video and audio chat into their primary customer experience.
Currently in beta (as of this writing in June 2013) are two new components in our WebRTC infrastructure. The first we refer to as Mantis, which solves many of the challenges associated with hosting large multi-party calls. The other is Cloud Raptor, which gives developers access to a stream of events stemming from a WebRTC session, and through which developers can issue events and commands of their own. Raptor is what enables you for example to moderate calls, boot participants, and control whose audio and video streams are broadcast to all the other participants.
So, TokBox has what you need. In the short term we can help you get up and running using OpenTok pretty quickly. Then we can discuss with you how to get you onto OpenTok for WebRTC and into our Mantis and Raptor beta program.
Google maps, ip location etc. working good.
But none of the services are locating a computer exactly where it is on a map.
Anyone know any api which can locate a computer on a map without user inputs.
I am tired of ip location, it is not at all exact and my client is not happy. :(
Thanks

What you're trying to do is not possible without specialized hardware. Google maps on cell phones without GPS uses cell tower station information. Most other phones use actual GPS receivers. With neither of those, the only way for your network-attached computer to tell where it is is by looking at who owns its IP address, which is what the IP location stuff does. Unfortunately, that database has pretty low geographical resolution. If you really want accurate and precise location information, you have to have a GPS receiver.
This cant be done unless you have some GPS device connected to the computer. But I guess it is forbidden in the licence to use real time tracking in Google Maps, but I might be wrong.
There's one more way, but I don't know how practical it is: visible wifi networks. If your PC has wifi hardware then you can often correlate the list of networks that you can see to an approximate location based on databases of networks and position. This is how e.g. iPod touches can locate themselves, and iPhones when there's poor GPS reception in built-up areas.
But even if your end-user has wifi hardware and you can somehow read the network list from it then I'm not sure if there are public datasets for this though.
The W3C Geolocation API allows websites to request the user's best available location from the browser. In some cases this will use IP geolocation which you've already seen to be inaccurate, but it can sometimes do better.
The API is agnostic to the device and the method used to obtain location; on an iPhone, the Geolocation API may use cell tower triangulation, available WiFi network lookup or GPS satellite geolocation, or some combination. On Firefox or Chrome on the laptop, Google uses WiFi networks and IP address to give a location which is often much, much better than IP geolocation alone.
If you had a GPS attached to your computer, it's possible that your browser could take advantage of that too -- it's expected that future versions of Internet Explorer will support the W3C Geolocation API using the Windows 7 Location Platform, which can accept location from an attached GPS or manual entry or some other plugin.
