Hello, I live in a residence and I want to buy somehting quite cheap to keep an eye on my bike that has suffered damage from someone ( I have a few suspects in mind ). I just need something that I can hide in bushes and can record continuously for approx 48hours (a week-end), no need for high quality image or anything fancy ... I can't find something that fits these criteria, any ideas ?

Well obviuously you're better at searching that kind of stuff on ebay so maybe you can give me pointers to what I should buy to achieve what I want : Something not TOO crappy at a reasonable price that can last for a long time either with it's own power supply or an external one.

I didn't know of trail cams, they definitely look interesting. I originally wanted to use a 12v battery from a bike ... They are quite small so they can be hidden easily. Well ... this one is perfect except for the price
