I'm going away in July and the last time we were away, we had trespassers use and vandalize our swimming pool. Idiotically, they posted what they did online, and were given the appropriate punishment. Next time, we might not be so lucky. I have a 24" iMac with about 150gb of free space. Is there any software that can take pictures every few minutes or so automatically over the course of a few days? Thanks.
