Designing Video Systems for Difficult Lighting Conditions
Technologies and time-tested tactics combine to take much of the frustration out of designing and installing video systems in difficult lighting conditions.
Challenging lighting conditions may be the biggest obstacle video system designers and installers encounter. After all, you can’t alter the laws of physics. And those laws dictate that you need light to get an image. Without light, there’s no picture. But light alone isn’t enough. The wrong kind of light, whether it is too little, too much or poorly located, such as a very bright backlight, does no good. It can even make the situation worse.
“Every camera needs light to see, but it’s the quantity and distribution of light that governs the quality of nighttime CCTV images,” says Kristin Seguin-Cory, national sales manager - U.S. and Canada, for Ottawa, Ontario-based CCTV lighting manufacturer Raytec Systems.
