When you need to see inside a wall, pipe, or duct, the camera you choose depends on how far you have to reach and how much detail you need. Two very different answers sit at opposite ends of the price spectrum: the RIDGID CA-25 Micro Visual Inspection & Diagnostic Handheld Camera and the Wohler VIS 350 Visual Inspection Camera.
Quick verdict
If you want a low-cost, portable camera for a quick look behind drywall or into a trap, the RIDGID CA-25 is the practical pick. If your work involves long drain runs or HVAC ducts and you need to know exactly where the problem is, the Wohler VIS 350 justifies its much higher price.
Comparison table
| Feature | RIDGID CA-25 | Wohler VIS 350 |
|---|---|---|

Where each product wins
The RIDGID CA-25 wins on price and portability. It is a compact handheld camera that fits in your hand, and the flexible cable and adjustable LED lights make it easy to look into dark, tight spots without disassembly.
The Wohler VIS 350 wins on reach, articulation, and reporting. The long push rod and pan/tilt head let you inspect side walls and joints, while the digital meter counter and built-in transmitter add precision for locating blockages.
Product notes
RIDGID CA-25 Micro Visual Inspection & Diagnostic Handheld Camera
The CA-25 is a genuine pocket-sized troubleshooting tool. Its 17 mm aluminum camera head fits through small openings, and the four ultra-bright adjustable LED lights illuminate dark spaces while you watch the 2.7-inch display. The waterproof camera head and flexible 4-foot cable make it useful for quick inspections of pipes, wall cavities, HVAC systems, and machinery. At $49.99, it's an extremely affordable way to start doing visual checks. The main limitation is the short cable: you'll need to position the camera head close to the problem area. If you're a DIYer or technician who wants a quick look without tearing things apart, this small camera is a practical, budget-friendly choice.
Wohler VIS 350 Visual Inspection Camera
The VIS 350 is built for professional inspections that demand serious reach and control. Its 100-foot push rod takes you deep into pipes, ducts, and conduit, while the pan-and-tilt camera head rotates 360° and tilts 180° so you can examine side-wall details and joints that a fixed head would miss. The 7-inch monitor can be tilted or detached with a 6-foot cable for awkward positions, and the digital meter counter shows how far the push rod has traveled. The built-in radio transmitter helps identify the location and depth of a blockage when paired with the L200 Locator. At $3,799.99, this is a major investment, and the unit is sold used, so its condition matters. The main limitation is the cost and bulk: this is a self-contained system in a rugged case, not a pocketable tool. It's the right call when you regularly inspect long runs and need precise, documented results.
Final choice by use case
Choose the RIDGID CA-25 if you want a low-cost, handheld camera for short inspections around the house, and you can get the camera head close to the problem. Choose the Wohler VIS 350 if you need to inspect deep, lengthy runs in pipes or ducts, and you want distance and locator information to act on.
