Yes, in the UK, sunny South Wales. It may suprise most, but these people are mostly active during the day when I am at work and my elderly neighbour is home alone, but 'night vision' would be a welcome addition. The trouble with nightvision, using IR to enhance the image, is that it doesn't work through glass, I believe that is the case anyway, and these cameras are located indoors pointing outwards.
The main problem is budget, as you can tell from the setup. In a strange way I'm proud of the fact that it's the cheapest setup you've heard of!! lol At this moment in time I cannot afford 4 cameras that cost £200+ each and my neighbour can afford even less (pensions are pitiful in the UK).
I fear that for every question I answer you experts will have 5 more questions for me, so please be patient
