CAMERAS

摘要

"When an ultrasonic system sounds a warning, are you going to get out of the cab to check what's there?" asks Vision Techniques sales manager Andrew Kendall, summing up the attraction of reversing cameras. "Seeing is believing." A truck reversing camera kit can cost as little as £250 or as much as £700. Apart from differences in quality, the additional cost is justified by extra features. Good images depend on a clean lens, so consider cameras with built-in shutters that open only when reverse gear is selected. Alternatively, some cameras have integrated wash-wipe. If good camera performance in the dark is critical, check the number of infrared LEDs they have and the claimed night range: 5m to 15m is common.
