Wireless Endoscope 4K

It uses Wi-Fi to stream the inspection-camera feed to a smartphone or tablet. You typically view the live image through a companion app rather than connecting the camera directly to an HDMI monitor.

Its narrow camera is intended for confined spaces such as pipes, engine bays, wall cavities, and appliance gaps. The useful feature is the live phone view, which lets you inspect areas that are difficult to see directly.

The camera creates or joins a Wi-Fi connection for video streaming, so mobile data is not the core requirement. Your phone normally connects to the camera's wireless network and opens the supplied viewing app.

The description specifically supports smartphones and tablets, provided the device can connect to the camera's Wi-Fi network and run its app. Check whether the app supports your Android or iOS version before purchase.
