Seewire: USB Endoscope Camera

Seewire is a USB camera app (USB webcam, UVC / OTG camera) for Android. It shows the picture from a wired USB camera on your phone: USB endoscopes and borescopes (inspection cameras), USB microscopes, webcams and HDMI-to-USB capture cards that follow the UVC standard. Plug the camera in with a USB-C cable or an OTG adapter, and the picture opens.

WHEN IT DOESN'T CONNECT, IT TELLS YOU WHY
• Connection diagnostics checks USB OTG support, permissions, the camera type, the video format, power and the video stream, step by step.
• Each problem comes with a plain explanation and what to try next.
• If it still doesn't work, send a problem report from the app. We answer in the app within 2 weeks, and some fixes can be applied with one tap.

SEE AND RECORD
• Photos and video recording, with sound from the camera's microphone or your phone's
• Pause, loop recording, and recording that continues when you go to the Home screen or the screen turns off
• Freeze the picture to look closely, then save it
• Zoom, rotate, flip, fit or fill
• Brightness, contrast, white balance and other camera adjustments
• Date and time stamp, grid, crosshair and ruler
• Picture-in-picture, and volume keys that take photos, zoom or start recording

MEASURE AND ANNOTATE
• Calibrate with an object of known length, then measure lengths and diameters
• Add arrows, boxes, ellipses, text and freehand marks
• Annotated photos are saved as a separate copy, and the original stays as it was

SEEWIRE PRO (ONE-TIME PURCHASE)
• No ads
• Inspection report PDF: up to 30 photos with notes, dates and measurement tables
• Custom watermark: your text, logo and position
• Advanced measurement: angles, areas, several calibration profiles and CSV export
• Time-lapse
All core features stay free: connecting, viewing, photos, recording, resolution, connection diagnostics, problem reports, basic measurement and annotation.

YOUR PHOTOS STAY ON YOUR PHONE
• No account and no sign-in
• Photos and videos are saved only on your phone
• Apart from ads in the free version and Google Play billing when you open Pro, the app sends data only when you send a problem report yourself, and then checks only for the answer to it. You can see everything in the report before you send it. Reports never include your photos or recordings; a 3-second video sample is attached only if you turn it on.
• The free version shows banner ads only in the gallery, connection diagnostics results and sent problem reports, one per screen. There are no ads on the camera screen.

REQUIREMENTS
• Android 10 or later, and a phone that supports USB OTG (USB host)
• A wired USB camera that follows the UVC standard and sends MJPEG or uncompressed (YUY2) video
• Not supported: Wi-Fi endoscopes, cameras that only send H.264, and cameras that need their maker's own app. Some of these non-standard endoscopes can be tried with an experimental connection, but it is not guaranteed to work.
