I use to try to see how my sankes doing when I am out. I set up a web cam right outside the cage and hook it up to my laptop near the cage. The setting of the web cam is in a way that it record only when there is movement of the snakes, but unfortunately, the snake moved may be around 10 minutes everyday then I gave up. One time I try to put the web cam inside the cage to see any difference, but my snake bit instantly and nearly tear the cable of the web cam. Recently, I got a DV cam with nightshot function, I may try again to see how things going...forgot one thing, my snake is a gaboon viper....wish you can get some good shots..
