I ended up buying a Foscam FI8904W (I purchased from Amazon through the seller
"Foscam Digital Technologies LLC" which seems to be the US distributor. I'd imagine buying direct from Amazon.com as the seller would be safe, too, but they were out of stock when I ordered.) If you look at the Amazon reviews, my review is on there and mentions iCam
Anyway, I installed the camera with a simple 2-light flood light above it. This lights up the area well but means I don't know how well night vision works on the camera.
I've been VERY happy with the Foscam FI8904W. It was just as easy to set up as the AirLink models I use indoor, and I feel the Foscam has much higher image quality -- especially color quality. It has been just as reliable (doesn't freeze or lose connections) as the inside cameras. Also, I am using it wirelessly and it has worked great.
The only thing I can complain about is that the plug is pretty large -- so you'll have to make a 1" or so circular opening in your wall or outdoor surface to snake the wire inside. This was fine for my install, but I see it could cause issues with certain installation locations if you couldn't easily drill a 1" hole.
1 thing to know: you must set up the camera for the first time with it plugged in via ethernet. That is how you choose the wireless network. If you changed your router out or changed your wireless network name, you'd need to re-connect to the camera through ethernet to change the settings. Keep this in mind.
Here are two sample images. Note: camera is mounted approx 16' high and faces downwards at a pretty steep angle.
NIGHT (11pm -- note: this is not an IR image, it has the floodlight above it)
low light DUSK (7pm)
Daytime performance is even better.
