Well, I've now visited an Aldi and it was surprisingly ok. Friendly and knowledgeable staff and a clean but rather random layout. Got an Aldi-cam (I made that name up) for £35. Infra red, programmable, waterproof (IP34), recordable and timeable. 3 year warranty. Tried it indoors last and it captured the dog's nocturnal wanderings.
The cheap wildlife camera traps can produce surprisingly good images in the right conditions. I left one pointing across our driveway for a day or two, and got this.
