Why NOT video cameras?

• CCTV systems are expensive. Installation can also be expensive, as well as logistically difficult.
  
• Choosing the correct camera equipment requires some technical knowledge (exhibit 2.2).
  
• A single camera can effectively view a smaller area than would be intuitively expected, hence many applications can require more cameras, equipment, and expense than was originally expected.
  
• Cameras can be stolen or vandalized.
  
• Ongoing maintenance and operational support are required.
  
• Some applications or areas do not warrant camera use.
  
• Some communities or individuals will challenge the legality of using cameras.
  
• Insiders with full knowledge of the installed video system's capabilities can possibly circumvent the system to their advantage.
  
• If it becomes well known where cameras are being used at a school, students may simply move their misbehaviors to a different part of campus.
