Cables: Preventing connector corrosion

When cables and cameras are exposed to moist and marine environments, corrosion can occur. Corrosion causes refined metals to convert a more stabilized form such as an oxide or sulfide. Cable corrosion can cause poor connection, leading to camera image issues and loss of video feed.

To prevent cable and connector corrosion:

  • Corrosion can be prevented through regular cleaning of connections with products like WD40, DeOxit DN5 or a mixture of vinegar, salt, and baking soda.
  • The industry standard for protection against cable corrosion is to use a silicone dielectric grease with tensioned electrical wrap or heat-shrink tubing over the connection. The silicone dielectric grease fills and air spaces and helps keep moisture out of connections.
