What's the best Android app for inspecting pipes and hard-to-reach areas with a USB endoscope camera?

Endoscope Camera / USB OTG is a utility application that enables Android devices to connect with USB endoscope cameras via USB On-The-Go support. This app is particularly effective for tasks like plumbing checks, automotive diagnostics, or home maintenance, where visual access to tight spaces is crucial. Key features include a real-time HD video feed, snapshot and video recording capabilities, and adjustable settings for brightness and contrast to enhance image clarity. Users report that the interface is straightforward, requiring minimal setup for quick deployments. However, some reviews note occasional compatibility issues with certain Android models or endoscope brands, and a minor lag in video streaming can occur under suboptimal conditions. In real-world scenarios, such as identifying blockages in drainpipes or examining engine components, the app proves valuable by reducing the need for specialized equipment. The ability to save and share recordings directly from the device adds practical benefits for documentation and professional consultations. While not flawless, its consistent performance in most use cases makes it a go-to solution for DIY enthusiasts and tradespeople alike.
