ESP32-Cam Camera Microphone
This article is about “WiFi ESP32-Cam Camera Microphone (SpyCam)” firmware project which has been made by Ai Thinker ESP32-Cam module, the circuit (or WaveShare Sound Sensor) and arduino source code (.ino) files.
The firmware includes a Web Application (WebApp), to access to this WebApp, there’s no need to internet connection or installing a software or application. All you need is a smart phone or computer which supports WiFi and a web browser (Chrome or Firefox).
The default WebApp address is 192.168.4.1, right after loading the page, it starts to cache the video and audio data for the online video and audio stream. Then by click on the “Play” button, it starts playing the online stream.
With Chain Network feature, which is based on the “ESP32 WebApp Builder” project, optionally you can join up to 4 devices, either ESP8266 WiFi Microphone/ESP32 WiFi Microphone or ESP32 IP Camera and ESP32 Camera Microphone to a local network and access to the devices via “Network” section of the Web Application.
With inserting a memory card into the MicroSD slot, you can enable the auto-recorder/record-trigger mode and record the audio and video.
Also it has a time-lapse feature which record the video frames during a longer time and capture cycles.
You can play or export .AVI file of the recorded videos in the file manager section of the WebApp.
