SJCAM

Universal Windows 10 App (UWP) for SJCAM action camera

Introduction

As I owned a SJCAM action camera recently (M20), I started to write an Universal app for windows 10 family. The idea is to support all the parameters from the camera. Currently I can only test on the M20 camera, as this is the only one I own.

Features

• Auto connect to camera, the idea is to avoid the user that has to quit the app to connect
• Snap pictures and takes videos
• Adjust resolution, brightness, sharpness etc etc, well, to support all the camera settings
• Access to camera storage through network, and be able to retrieve photos and videos
• Sexy design (Important!)
• No ads

Commands

Everything is based on GET Request to the camera, which has a Base URL on http://192.168.1.254/ Get request is build such as http://192.168.1.254/?custom=1&cmd={COMMAND}&par={PARAM}
