Wanhive Netcam

Video streamer application for the Wanhive IoT Platform.

Features

• Multistreaming support. The sensor and control data interleave seamlessly with the video stream:
  • Geolocation data
  • Gimbal (pan/tilt) control
• Firewall friendly.
• Mobile network (4G/5G) friendly.
• Supports SSL for data security.

Components

• Streamer: Outputs a sequence of JPEG images (just like MJPEG). Supports pan, tilt, and geolocation.
• Viewer: Captures and displays the video stream and sensor data from a Streamer. Keyboard controls:
  • Toggle geolocation (L)
  • Pan (A/D)
  • Tilt (W/S)
