This paper discusses reasons for using video tape in arson investigations, types of equipment needed, and the current legal status of using video tapes in courtroom evidence presentations.
Abstract
The use of video equipment in arson investigations is a relatively new procedure. Advantages include the instant replay capability, a verifiable time sequence and audio capability, and a ready source from which still photographs can be reproduced after initial filming. Disadvantages are the cost of equipment, need for additional manpower, necessity for good lighting, heaviness of equipment, and the fact that damage to equipment may occur due to adverse fire scene conditions. The heart of any system is the video tape recorder (VTR) and camera. The two main types of VTR's are the reel-to-reel type and the cassette or cartridge type. The cassette type is preferable. The camera is usually matched to the recorder by the manufacturer. Fast and zoom lenses should be a prime consideration; they can be used for wide angle and short telephoto shots and under poor lighting conditions. Auxiliary lighting in the form of portable lights should be included in the equipment list. The cost of a typical VTR system with camera and accessories is approximately $2,200. Legal questions concerning video tape usage arise from the fourth, fifth, and sixth amendments. Despite recent challenges, many courts, have held that video tape evidence is admissible. Eighteen footnotes and a seven-entry bibliography are provided.
