The PipeScope Lab Camera Head Sizes Database is an engineering reference designed to help plumbers, drain cleaners, and diagnostic technicians match specific camera heads to pipe dimensions, bend tolerances, and fitting configurations. Choosing the correct camera head diameter is the single most important factor in preventing lost or bound equipment inside commercial and residential drainage systems.
How to Navigate the Database
Rather than categorizing cameras solely by price or brand, our database catalogs physical head specifications drawn directly from manufacturer technical drawings. Key parameters include:
- Camera Head Outer Diameter (OD): Measured in millimeters (mm). Standard sizes include 12.5 mm (micro-borescope), 17 mm (compact branch line), 23 mm (standard residential lateral), and 30+ mm (commercial/municipal mainline).
- Rigid Housing Length: The length of the non-flexible camera body, which determines cornering radius across swept elbows and P-traps.
- Flexible Spring Assembly: The design, length, and elasticity of the stainless steel spring connecting the head to the push rod.
- Lighting & Sonde Integration: Indicates whether an integrated 512 Hz dipole sonde transmitter or adjustable LED ring is embedded in the head assembly.
Matching Head Sizes to Specific Pipe Applications
To avoid getting a camera stuck or suffering poor illumination in oversized voids:
- 12.5 mm to 17 mm Heads: Engineered for 1.5-inch to 2-inch branch lines, kitchen sink traps, residential roof vents, and tight P-traps where larger heads mechanically bind.
- 23 mm to 25 mm Heads: The industry standard for 3-inch to 4-inch residential sewer laterals and building mains, offering the optimal balance of image resolution, LED output, and cornering ability.
- 30 mm+ Self-Leveling Heads: Optimized for 4-inch to 8-inch commercial sewer mains where high-output LEDs and wide-angle imaging are necessary to illuminate large pipe voids and prevent dark, unreadable video footage.
Centering Skids and Pipe Diameter Range
When operating a compact 23 mm head in a 6-inch or 8-inch commercial main, the camera head naturally rests on the pipe invert (bottom), where residual water, slime, and debris submerge the lens. To overcome this, protective centering skids or guide balls must be attached to lift the optical axis into the center of the line. The database specifies which skid mounts are compatible with each documented camera head.
