In this setup, the power leads yellow/black are soldered directly to the back of the Raspberry Pi Zero board. The Raspberry Pi boards are being powered with a 12V DC 1500mA wallwart connected to 5A DC-DC converter set to around 5.2V output (this is a temporary setup for testing, after testing that everything is working fine, each Raspberry Pi Zero W should have a separated power supply). Each Raspberry Pi Zero W board is connected to a camera.
The setup for the cameras consists of 4 Raspberry Pi Zero W with a Sandisk Ultra 16GB class 10. A friend of mine has suggested putting a beefy cap in parallel with the RPi power input Cameras Setup Note: I have found that my SATA drive is capable of being powered by the RPi 2 USB without a powered USB hub. Note: I have been doing some experimentation with powering RPi 2 and 3 and found that using a 12V 1500mA wallwart adapter and a 3 or 5A DC-DC converter with short leads seems more capable and often cheaper than a big 3A wallwart adapter, and gives you a 12V supply for other associated hardware. The Raspberry Pi is being powered with a 12VDC 1500mA wallwart connected to 2A DC-DC converter set to around 5.2V output. There is a 1TB SATA drive connected to the Pi with a SATA-USB cable. The Raspberry Pi Hub setup consists of a Raspberry Pi 2 Model B (if you have a RPi 3, use that board instead) with a Sandisk Ultra 16GB class 10.

4x Raspberry Pi Camera (read What’s the Best Raspberry Pi Camera For Your Project?).4x Raspberry Pi Zero W (with built-in Wi-Fi).1x 5V power supply capable of powering both the Raspberry Pi and the SATA drive separately.1x MicroSD Card 8 or 16GB – the fastest you can afford.1x Raspberry Pi 3 (or any other model you have).
Here are all the parts needed for this project. The following figure shows a high-level overview of the project.
The surveillance system built includes: one Raspberry Pi acting as a HUB with 1TB SATA, and 4 cameras (each one connected to a Raspberry Pi Zero W) that can be monitored through the HUB.Īll devices are connected to your local network, and you can access all the cameras through the hub using a browser on your computer (or other device on the local network).
