(Chapter 2 Video Surveillance, Continued)
Standard-resolution solid-state cameras can cost between $300 and $1,000. High-resolution cameras can range anywhere from $1,500 to $8,000. For most school applications, the standard-resolution camera is probably adequate. The less expensive cameras (nearer to $300) need more light to accurately capture a scene. The more expensive cameras ($1,000 or more) tend to be more sensitive, using more sophisticated electronics so that they require less light to accurately capture a scene.
