Have you ever wanted to monitor your home, garden or office, but didn’t really know how to go about it? Even though decent commercial Wi-Fi Security Cameras are not terribly expensive, they still cost much, especially when one wants to buy several of them for an entire house.

Max, a young engineering enthusiast/hobbyist writing on instructables.com, proposes how to make your own DIY Surveillance camera for approximately 15 USD per camera. The necessary supplies include:

• ESP32-CAM with OV2640 2MP camera sensor

• FTDI USB to Serial converter (for programming) + Female-to-female jumper wires

• 4GB MicroSD card (TF Card)

• Clip-on antenna

• TP4056 1-cell Li-Ion Charging module

• (x2) 18650 3.7V 2600mAh battery

• Mini SPDT sliding switch (3A toggle switch is recommended)

• Some 24-gauge electrical wire

• 3mm Red LED

• 220 Ohm resistor

• Cylindrical plastic container (choice of camera's enclosure is optional)

• GoPro mount accessories (if you want your camera to be attached to a wall)

Max has carefully documented all the necessary steps for building this project and has also created an easy-to-follow YouTube video tutorial about it. So, you can add an additional layer of security to your personal or professional space with this home-made Wi-Fi Security Camera. The code and its extensions, along with additional information, specifications, possibilities and more, can be found at the ESP32-CAM MJPEG2SD GitHub repository.
