Today almost all businesses of mid to large size rely on cameras for surveillance. It's amazing how this sector of the loss-prevention industry has boomed. The cost to equip a store with camera equipment just 10 years ago was outrageous. But now the price has dropped drastically. Using the Internet, business owners can even monitor their cameras remotely from anywhere in the world. Even small businesses are poised to benefit from increasingly camera cheaper technology. AT&T is selling a system that costs around $200 for a single location. Internet monitoring for a single location will run you about $10 a month. That figure can go up to $40 for multiple locations.
