I believe, SEC South Coast Equipment cameras is an acceptable choice for home use only. If it doesn’t break on the first job, you can hardly push 50 feet. For a starter company, good starters are Vu-Rite or Easycam with the 2-year warranty. If you are just viewing sewers and don’t much recording, Easycam all the way pushes all 200′.
The original Vu-Rite is a tank in a comparison with SCE cameras and the replacement parts are affordable. If you want a good into camera buy a Vu-Rite or a good priced Ridgid Seesnake or General Gen-Eye. Ridgid Seesnake is tops for those who can afford one. Seesnakes puts out good cameras but cost way too much to buy and repair.
