No they are not to hard to setup. The cams I use are board cameras whitch I buy off ebay. These cams can be focused down to a few inches and are ideal for this job. if you go to
http://uk.geocities.com/brett.oliver...s/Shematic.gif it will show you there how it is wired up in a nest box. If you use it in the daytime you will not need to use any lights but if you want to veiw them at night you will need to wire some white leds or some infra red leds. The cams are wired to the computer though a capture card and with I-Cature software running all movement in front of cam will be recorded on the computer. Which ever ones you use it dosent seem to bother the mice.If you need more info let me know and I will try to help.
