Q: What are those horizontal lines that wiggle on a CCTV camera?

Wiggling hoizontal lines are called "smear" or "blooming." Most security cameras are single chip CCD sensor cameras. When a CCD sensor is faced with a light that is so bright that overwhelms a pixel, it will affect all the pixels below it. So what you are seeing is the electrical interference of a light sensor being overwhelmed with light. A CMOS sensor does not have the "line" problem, so CMOS won't give you the lines, but too much light will still burn out pixels -- and that's the real problem.
