Just out of interest I have recently purchased a new TZ70 camera to replace my ageing TZ5. On of the enhancements is the inclusion of WiFi. Using this I have set the camera up on a tripod in the garden and focused it on one of my bird feeders. By setting up the wifi to work through my home system I can now control the camera, zoom etc and operate the shutter using my Android smartphone or tablet without having to be anywhere near the camera.
I also set it up the other evening to take some shots of a hedgehog that comes in to our garden every evening looking for food. By putting some food in a certain place I can focus the camera on the food and take some pictures.
