camera-streamer

Example for ESP32 TimerCam rebuilt using ESPP to stream video over the network

It uses RTSP + RTP (over UDP) to perform real-time streaming of the camera data over the network to multiple clients.

rtsp_client_server_compressed.mp4

To facilitate easy connection to the camera, it also runs a mDNS server to advertise the camera's IP address / port that the RTSP server is running on.

Hardware

This sample is designed to run on the ESP32 TimerCam (Amazon Link).

The ESP32 TimerCam has the following specs:

• 8MB PSRAM
• 4MB flash
• OV3660 image sensor (3MP, 66.5 DFOV), (8-/10-Bit RAW, RGB, and YCbCr output, compression), XCLK frequency: 10 MHz
• SH1.0-2P Battery Interface
• I/O: LED, Button
• RTC (BM8563)
• Battery
