More and more interest is being shown in the ability to control cameras wirelessly from devices such as iPad, iPhone, as well as Android phones and tablet computers.
One of the most stable methods and gain in popularity is with a device called CamRanger through which you can control either a Nikon or Canon DSLR with either the iPad/iPhone or Android phones or tablets. What you get is a wifi router, a usb cable to hook the CamRanger to your camera and a charger for the rechargeable battery that comes with the CamRanger. That will cost you just right at $300.00 +/- a few cents. That kit can be bought from various places such as
http://www.camranger.com and other online merchants such as
http://www.amazon.com/CamRanger-Controller-Wireless-Control-Computer/dp/B00AA478UQ/ref=pd_sim_p_4?ie=UTF8&refRID=020SBJS2RAT6CBW7EYDD or even ebay at

You will receive instructions where to download the app you need when you purchase your CamRanger. Demo apps are available at
http://www.camranger.com for all the CamRanger equipment.
In addition to the Camranger, there are two other devices that you may also purchase that will assist you in the usage of the CamRanger. On is a motor that you put on your tripod and then fix your camera to it so you can remotely turn your camera left or right and up or down and to go with that there is an additional module that makes the motor wireless as well. The combination of those two items will cost you roughly $230.00 but I would just point out that you can remotely control your camera from a phone/tablet device without those two items although they do enhance the usage and the experience. With the motor you then can control all aspects of your camera remotely except the zoom. Some say you can control all of it at up to 150 from where you sit, whether it be on your deck, inside your home, or sitting in your car out of the elements. You will find the pt hum and motorized tripod at

The CamRanger is a repackaged portable wifi router with the name of TP-Link MR3040. A company named XtremeTether has also repackaged the same basic setup as CamRanger, the router, usb cord, and charger, and sells their product on Amazon as well and can be found at

http://www.amazon.com/TP-LINK-TL-MR3040-Wireless-Portable-Compatible/dp/B0088PPFP4/ref=sr_1_1?s=electronics&ie=UTF8&qid=1399681875&sr=1-1&keywords=tp-link+mr3040If you go this latter route, you will need to change the dns address for the router which is simple to do and only takes about five minutes at your keyboard. Then you will use another app called DSLR Controller that you download through the Google Play Store at a cost of less than $10.00 so by now you are up to less than $50.00 for this method. You will want to go to http:www/dslrcontroller.com and check their list of eligible devices to see if your camera and Android phone or tablet are on the list of devices that are compatible. If your camera/phone/tablet are eligible, there are instructions there for what you need to do to enter the new dns address into the router. DSLR Controller is a beta app but is stable. I have been using it for about 1.5 years now tethering my Canon 5D2 via usb which this app also allows so you can use this app and not bother with the wifi router at all if you don't mind being tethered. The speed of the exchange between your camera and tablet/phone is faster with usb than with wifi and other than being tethered there is no functionality lost or gained either way, usb or wifi. I have been using the TP-Link MR3040 route only about three months now and it performs quite well. You can also add on the controlling module and the tripod motor for about $200 more and still have less in than if you bought the CamRanger and still have the same identical equipment.
If anyone is interested in this or think you are, I would suggest that you go watch a couple of videos about the CamRanger. Here is one I think you should watch for sure and at the end there will be links to others you might want to view. There is also a short demo of how DSLR Controller works on their website that I would urge you to watch. The app is rich in features that allow you to very simply do things that are a bit more difficult without such an aid as this. I can assure you that it is pretty neat to be able to sit inside your house with your camera on a tripod in the backyard aimed at a bird nest, or where sitting in your car overlooking a stream where deer come to water late in the day, or especially when it's cold outside and you can sit in your car and shoot wildlife at a distance without spooking them. Each person has their own reason to enjoy the features available in these setups, or not.
Here is that video I recommend you watch:

We'll try to find the answers if we don't have them.
