If you have a spare Android phone lying around, you can turn it into an IP camera very easily.
There’s an App on the play store called – surprisingly – IP Camera.
This app allows you to view the phone’s camera as if it was an IP camera.
Once installed, you can use the Tinycam App mentioned in this post to view the camera from afar.
To view it, just enter in the phones address with the port and /videofeed appended into the Edit JPEG image address and you will be able to view the webcam. e.g. http://10.1.1.1:8080/videofeed
