There are a number of questions that need answering when considering current and future cameras. Some will be answered thanks to the expert help of a systems integrator, A&E consultant or product manufacturer.

An Infinova white paper establishes a manager's checklist for cameras.

Among the Basics:

• What do you want the cameras to see and what is the distance?
• What types of lenses are needed? Wide-angle, normal, telephoto? Can varifocal lenses be used?
• What resolution is needed for each camera?
• Are megapixel, high-resolution or high definition cameras needed? How about thermal?
• Can the video management system accommodate the features of the cameras?
• Are licenses required for the digital cameras?
• How many images per second are needed for each camera?
• What is the total number
