Hi, I really need some help. I want to make a video surveillance system for 400 $. Main purpose of the system would be to watch how employees act when we are away. The environment is very dusty. There are at least 2 rooms, which must be monitored (6mx5m and 6mx12m). Also 1(or more) cam is needed for outside. There must be a possibility to access surveillance system from the internet. In the future (when I get extra money) I want to increase number of cams. I prefer ip cams. Any suggestions?
