Many thanks. Actually I rarely visit this forum (I have never heard of Starlights, nor do I know which floodlights are favoured here!) so your recommendations are very useful.
I'm very much a hobbyist, and am also retired so always looking for cost-effective solutions ;0). I've never spent more than £50 on an IP cam and happily am still using devices that I bought >10 years ago.
One of the main appeals of the Netatmo as a 2-in-1 device is that it would be very simple for me to install (I'm awful with DIY) - I could simply remove the existing wall light and replace it with the Netatmo. Having a separate light and cam would require more wiring, which I would probably need to get someone in to do (increasing the cost again). I also quite like the idea of an LED light, as it's low energy and long-lasting. I'm seriously thinking of a solar LED option at the moment.
