This article will discuss building a security system with an ESP32 camera. I will start from the very beginning and show the whole process of how to make it.

ESP32 Camera an IoT Device

ESP32 is an IoT device, and it is to make the device smart. A 32-bit Cortex M0 processor powers ESP32 and has a built-in WiFi module. Also, ESP32 is a low-cost microcontroller with a built-in WiFi module.

In addition, it has 8KB SRAM and 64 KB FLASH memory. It has a built-in crypto accelerator that helps the device access different networks. ESP32 is compatible with Arduino IDE and has many libraries that help you use various sensors and other components.

Security Cameras With ESP32

If you want to add security at home or office, then the ESP32 security camera is the right option. You can use this Camera for monitoring purposes as well.

You can get security cameras with ESP32, an intelligent device capable of providing advanced features. These cameras will help you track the intruder’s movement and alert you.

Another great feature of the Camera is saving a video on an SD card. So, if you need to save it, this is the right option.

Some of the benefits of the security cameras with ESP32 are below:

  1. Easy to Use

The device is so easy to use, even for a newbie. The Camera has a built-in WiFi module, so you don’t need to install any third-party app to access it. Another advantage of this Camera is that it allows you to access your images in the cloud. 

  1. Budget Friendly

You can purchase this device at an affordable price, as several companies provide the product at a discounted rate.

Easy Installation:

It is a standalone device, and you don’t need to buy a separate camera to monitor it. Furthermore, you can install it in any location with WiFi connectivity.

Building Security System of ESP32

If you need to learn about building Security Cameras. Here’s how you can do it:

  1. Buy Parts

Before you build a security system with ESP32, you must check the specifications and the budget. ESP32 is a microcontroller board that uses a 32-bit ARM Cortex M0 core and offers WiFi, Bluetooth, Ethernet, GSM/GPRS/EDGE communications, and an ADC/DAC peripheral interface.

  1. Connection

ESP32 module uses a camera to monitor whether or not the front door. So we must tell the module whether the door is open or closed. Three pins can help us: VCC, GND, and SCLK.

  1. Connection With WiFi  Module

Once everything is connected, connect the ESP32 to the router using the WiFi module. With the ESP32 working, it’s time to plug in the WiFi modules so they can talk to it. It’s easy to plug the modules into the ESP32; just remove the case on the bottom of the board and slide them in.

  1. Configuration

I will talk about setting up the ESP32 in this tutorial because configuring it is necessary for using the ESP32 as a WiFi Access Point (AP).

  1. Enabling

Lastly, it’s straightforward to enable the cameraESP32 module. You need to do only two things: 1) connect the Camera to a serial port and 2) tell the camera module to take photos in real-time.

Other Options in the Market

Although there are many options, only some are as cheap as others. You don’t need to worry, as several companies provide different types of security cameras with ESP32 USB webcams. But the ones that are cheap and easy to use are the most preferred option by customers.

Best Ways To Utilise ESP32

In the last few years, the security sector has witnessed several changes. A person’s privacy and security are of utmost importance. The advancement in technology and the growing awareness of the world regarding cybercrime have increased the demand for a better and more robust security system.

As we know, new devices like smartphones and tablets can be used for home security as they contain many advanced features. However, it is essential to have a sound monitoring system for safety. Many applications available in the market today help you install an IP camera, but it is only possible to install one in some rooms of your home.

Investing in a robust and high-tech security system is the only way to keep yourself safe. However, to install the best quality camera for your home, you must understand its capabilities and the best application.
