1. Project Overview
This project is developed based on the ESP32-CAM module and gimbal, aiming to construct a remotely controlled video surveillance camera system. In this project, we will not only learn how to use the ESP32-CAM for video capture but also how to control the gimbal rotation with the ESP32-CAM.
Utilizing the powerful features of the ESP32-CAM, combined with the internet, users can monitor the target area anytime and anywhere through their mobile phones or computers.
2. Required Hardware
Before we start, we need to prepare the following hardware components:
-
• ESP32-CAM module x 1
-
• FT232RL FTDI Mini USB module x 1 (for uploading code to ESP32-CAM)
-
• MB102 breadboard power module with pins cut off x 1 (to power the gimbal servo)
-
• 18650 battery holder x 1
-
• 18650 batteries x 2 (or four AA batteries with the corresponding battery holder)
-
• Mini gimbal with 2 SG-90 servos x 1
-
3. Construction Instructions
In this section, we will gradually introduce how to set up the smart video surveillance camera.
3.1 Preparation First, ensure that you have installed the Arduino IDE development environment and added the ESP32 board to the IDE.
3.2 Hardware Connection Connect the various hardware components according to the provided schematic. Make sure to connect the Tilt servo motor to pin IO2 and the Pan servo motor to pin IO14.
3.3 Software Configuration Install the ESP32 plugin in the Arduino IDE and download the project code. In the code, you need to configure your Wi-Fi network name and password in the corresponding variables. Then, connect the ESP32-CAM to the computer via the FTDI programmer and upload the code according to the instructions. After uploading, disconnect GPIO 0 and GND, reconnect the ESP32-CAM to the gimbal. Finally, open the serial monitor to record the IP address of the ESP32-CAM.
4. Remote Access Settings
To achieve remote access to the camera over the internet outside the home network, you need to build your own IoT network platform or find a commercial IoT solution to enable remote control of the gimbal and video connection. Here we can simply connect the camera to a computer and use video conferencing software for free remote access. However, under such conditions, it is not possible to remotely control the gimbal rotation.
Conclusion
Through this DIY project, you can enjoy a high-quality video surveillance experience and stay informed about the status of the target area anytime and anywhere. The process of building this smart video surveillance camera is straightforward and suitable for DIY enthusiasts.
