plug can do the job as long as it supplies at least 1A of power. We have ordered such a power supply which already has a micro-USB plug for about
US$10
SD card: as the Raspberry Pi does not have any storage on board, you need to add some so that you can install and run the operating system for this
device. Any SD or microSDHC should do the job, but we recommend using a Class 10 SD card. It's only around US$7
To connect this cam to your network, you also need some kind of network connection. One possibility is to use a LAN connection, but you would need
to put LAN cable to the point where you want to mount the camera. A better alternative is such a WiFi USB adapter for only about US$10:
That's all: for about US$120 we have all the hardware we need to build this HD surveillance cam.
Install Raspbian
At first, you should install the OS and software to the Raspberry Pi before mounting it all together. An OS is the basic operating system software that tells
the Raspberry hardware what to do. Linux is perfect for this. We have chosen Raspbian, as it's one of the most advanced OS for the Raspberry with loads
of help and tutorials on the internet.
You need to prepare the SD card to be able to run Raspbian on the Raspberry: this excellent tutorial from Adafruit will explain the necessary steps.
Now temporarily connect your Raspberry Pi board to LAN cable, a monitor (HDMI TV works out of the box, but a HDMI-to-DVI cable like this will do the job
as well) and a USB keyboard for the basic setup.
Insert the prepared SD card with the Raspbian installer on it and attach the power supply.
The Raspberry should boot up and guide you through the setup process as explained in this Adafruit tutorial. After this, you should have a basic Raspbian
OS running.
Be sure to enable SSH in Raspbian so that you are able to control the Raspberry device also when there is no monitor and keyboard attached. And you
should also enable the camera from the Raspbian setup menu so that we can use it for motion detection.
Now make sure your RPI is up to date:
sudo apt-get install rpi-update
sudo rpi-update
And also update all packages:
sudo apt-get update
sudo apt-get upgrade
Connect via SSH
Now that the basic setup is done, you should connect to your Raspberry device from your computer. You can connect to Linux console from any computer in
your local network and control it like you where sitting directly in front of it. This is very important as once mounted far away from your desktop, you need to
be able to make updates and change the configuration of this camera any time later without the need to detaching it from the wall and bringing it back to
your desk.
Remember that this cam is not just a dump cam device but a very powerful computer with Linux OS running on it. It's not limited to what we explain in this
article now; it will follow any development in software so that you will be able to install updated software and more modules any time later.
First, you need a software to connect to the Linux console on the Raspberry. For Windows, you will need the extra (free) software PuTTY. Download it from
the PuTTY website, install it and connect to your Raspberry Pi device:
