It is really cool to link Iphone to Ipad via bloothtooth and then can
Use my camera on Iphone as a spy camera. Then you monitor
It on the Ipad. The bloothtooth distance was impressive.
Friends are impressed with Ipad and blown away to see
The to "I's" connected.

App for this?

I use "camera for iPad". There's probably other ones out there, but they should all work pretty much the same.

You need to dowload it on both devices (iPhone and iPad) and then open it on both. It connects through Bluetooth, and whatever is showing on your iPhone camera will also show on your iPad screen. You can tap either screen to take a pic. There is a small lag time, and it only takes pics....no video. Pretty cool though.

How far away can you get before you lose the image? (And is there anything in the way like walls or is it line-of-sight?)

It only works as far apart as the Bluetooth signal can transmit, which is about 15 Ft or so (I think that's what it is anyway....haven't tested it myself). Walls and stuff don't affect it.

I know that's what it's rated for but Foo said: The bloothtooth distance was impressive, so I wanted to know what he's actually getting, not just what BT is spec'ed for.

if bluetooth doesn't cut it for you, the same apps are available to transmit over a wifi connection.

Ahhh....gotcha

Oh, then my other question to Foo would be: Why aren't you using Wi-Fi? (I'm not being sarcastic. Maybe you don't have a wireless router. I'm just curious why, if these same apps work over wifi, you wouldn't use that instead.)
Wi-Fi would make your spying much more clandestine, I would think.

Is there no app for doing this on the iPad with just a normal wireless camera, rather than just an iPhone?

I'm not 100% sure, but I seriously doubt it. To even get it to work with the iPhone, you need to have the app downloaded and running on the iPhone too. There's only a limited amount of Bluetooth devices out there that the iPad has the ability to connect to (certain headsets and not others, etc), so I doubt you'd be able to connect with a Bluetooth enabled wireless camera. Possibly there's a way to do it if jailbroken though?

Why not WIFI??
It was more of the novelty of using the iPhone and Ipad.
Bluetooth worked 2 bedrooms away and more. Signal carried though
2 walls. Having a IPhone set in any spot does not look as out of
Place as a camera.

There is one, but I think it's more for iPhone, but if I remember correctly, any idevice using the app can tap into the iPhone's camera and see what it sees on your screen, and even take photos.
