Wöhler VIS Inspection Cameras: A Selection Guide

The Wöhler VIS series is a family of professional inspection camera systems designed for wastewater pipes, flue gas lines, ventilation ducts, chimneys, and building cavities. These video inspection systems are widely used by plumbing contractors, HVAC technicians, facility managers, and NDT professionals who need reliable visual diagnostics in hard-to-reach areas.

While all VIS models share core capabilities—robust construction, integrated lighting, and video recording—the VIS 200, VIS 250, VIS 350, VIS 500, and VIS 700 differ in camera head options, push-rod length, imaging performance, and available accessories. Understanding these differences helps you select the most appropriate Wöhler VIS camera for your inspection work.

Wöhler VIS Series Overview

VIS 200 — Compact Entry-Level System

The VIS 200 is designed for straightforward inspection work where mobility and simplicity are priorities. Its compact camera head and lightweight reel make it well-suited for residential drains, small-diameter piping, and short-run flue or vent evaluations. It delivers dependable imaging performance without the complexity of modular components.

VIS 250 — Versatile Service Camera for Routine Diagnostics

Building on the VIS 200 platform, the VIS 250 offers greater reach and enhanced usability for everyday field service. It is engineered for plumbers and HVAC technicians who need a durable, self-contained inspection system capable of handling routine residential and light commercial pipelines with consistent reliability.

VIS 350 — Mid-Range System for Sewers, Drains, and Utility Pipes

The VIS 350 offers a balanced mid-range inspection solution with a detachable pan/tilt camera head, integrated distance measurement, and reliable on-board recording. It is well-suited to professionals who need a portable, self-contained system for inspecting residential and light-commercial drains, sewer lines, and ducts, providing greater maneuverability and documentation capability than entry-level models without the complexity of a fully modular platform.

VIS 400 – Modular Visual Inspection System

The VIS 400 introduces a modular architecture that supports multiple camera heads and rod configurations, allowing a single system to serve a broad range of inspection environments. It is a strong fit for professionals who perform mixed work across plumbing, chimney, flue, and HVAC ducts and require flexibility in both tooling and technique.

VIS 500 — Universal System with Extended Runtime and Connectivity

The VIS 500 is built as a universal inspection platform with interchangeable heads, long battery life, and documentation-friendly features such as WLAN and USB recording. It is suited to technicians who need a robust, adaptable solution for longer inspections, larger pipe diameters, and environments where streamlined reporting is essential.

VIS 700 — High-Definition Inspection for Advanced Requirements

The VIS 700 represents the highest imaging performance in the VIS lineup, delivering true HD resolution, precise pan/tilt control, and advanced locating capabilities. It is designed for demanding wastewater, flue gas, and industrial inspections where visual clarity, precise maneuverability, and comprehensive documentation are critical.

Our Recommendation:

• Choose the VIS 200 if you need a cost-effective, mobile inspection camera for shorter residential pipes and flue lines, and you do not require pan/tilt or HD imaging.
• Choose the VIS 250 if you want a service camera for routine plumbing and HVAC work, with built-in distance readout and locator functions for pipes 1½" and larger.
• Choose the VIS 350 if you need a mid-range inspection system with a detachable pan/tilt camera head and integrated distance measurement, offering greater maneuverability and documentation capability than entry-level models for residential and light-commercial drains, sewers, and ducts.
• Choose the VIS 400if you need a modular platform that can be configured for pipelines, chimneys, ducts, and cavity walls with different heads and rod options.
• Choose the VIS 500 if you want a universal inspection system with strong runtime, interchangeable heads, and connectivity (WLAN/USB) for documenting chimney and exhaust inspections.
• Choose the VIS 700 if your priority is HD image quality, precise motorized focus, pan/tilt control, and advanced wireless locating—ideal for demanding waste water, flue gas, ventilation, and NDT applications where image detail and documentation quality matter.
