🎥 ESP32-CAM Video Streaming Web Server

In this project we’re going to build an IP surveillance camera with the ESP32-CAM board. The ESP32 camera is going to host a video streaming web server that you can access with any device in your network.

You can integrate this video streaming web server with popular home automation platforms like Home Assistant or Node-RED. In this tutorial, we’ll show you how to integrate it with Home Assistant and Node-RED.

🤖 Telegram Bot: ESP32-CAM Take and Send Photo

In this tutorial, you’ll create a Telegram bot to interact with the ESP32-CAM to request a new photo.

Here’s an overview of the project you’ll build:
▫️ You’ll create a Telegram bot for your ESP32-CAM;
▫️ You can start a conversation with the ESP32-CAM bot;
▫️ When you send the message /photo to the ESP32-CAM bot, the ESP32-CAM board receives the message, takes a new photo and responds with that photo;
▫️ You can send the message /flash to toggle the ESP32-CAM’s LED flash;
▫️ You can send the /start message to receive a welcome message with the commands to control the board;
▫️ The ESP32-CAM will only respond to messages coming from your Telegram account ID.

📷 Discord Security Camera With an ESP32

Use an ESP32 Cam and a passive infrared (PIR) sensor to create a motion-activated security camera that will post a photo to a Discord channel, where you have access to create a webhook.

We'll build out the test circuit, using a breadboard and jump wire. We'll then build a wiring harness using Dupont connectors to allow for easy connections to the development board and PIR sensor.

We'll then use our choice of a wall or ceiling-mounted 3D printed case to contain our parts and our camera.

The ceiling-mounted camera makes use of an inexpensive decoy camera that can be purchased online.

📷 2 Axis controllable platform for ESP32-CAM for streaming video

In this project, we’ll attach the ESP32-CAM to a pan and tilt stand with two SG90 servo motors. With a pan and tilt camera stand, you can move the camera up, down, to the left, and the right— this is great for surveillance.

The ESP32-CAM hosts a web server that shows video streaming and buttons to control the servo motors to move the camera.

🔬 Automated Overhead Camera Assistant

This excellent automated overhead camera assistant runs on an Arduino Mega and is operated by typing commands in the serial monitor

Have you ever wished you had an extra pair of hands in the workshop to handle the camera, while you were concentrating on your project ? This build tries to help with this, by providing an automated camera assistant, that can automatically move between learned keyframe camera positions, or alternatively continuously pan between them from above your workbench.

The Camera Assistant is designed to hang upside down, moving parallel to the workbench. Furthermore in the relaxed position, the heavier lens in naturally balanced downwards, putting little stress on the steppers and bearings.

📷 Custom Handheld Pi Zero HQ Camera

This project stands out in the realm of DIY camera technology. At its core, the camera integrates a Raspberry Pi Zero (with a preference for the Pi Zero 2) and the High-Quality (HQ) Camera module, coupled with a compact 1.5" Waveshare OLED display. Its unique features include live preview, zoom-crop panning for manual focus assistance, file viewing capabilities, and an integrated 10-axis IMU for potential horizon level overlay applications.

This creation is less about competing with high-end cameras like the Sony Alpha series and more about providing a platform for custom software development and experimentation in camera design. The estimated cost of the camera, considering major components and a 35mm lens, stands around $185.00.
