This project is a mix of two projects. The bulk of the code is done by Bob Tidey and others with the 

RPi Cam Web Interface

 Project, found on github:

Along with that, we have some changes that we use to attach the servo mount control to the project, So the final system looks something like this:

We've made the entire process very simple by bundling all the commands into one simple install-pan-tilt-camera.sh script file. If you already have a Raspberry Pi setup, you could simply download this project and run that script, it should still work the same, but is not tested at the moment (Jump to 

 section).

Feel free to post issues on the github repo if you have trouble installing on a NOOBS or other linux on the raspberry pi.

The instructions below builds the system from a bare "Raspbian Lite" build, building the system entirely from the console, saving a lot of space, downloads-less, and is all the more lean of a system. If this sounds like something you're interested in building, then read on.

The original documentation for the RPi Cam Interface can be found here: 

. You should check this out if you have any issues with the interface or you want to find out what else it can do.

As we are starting out with a bare Raspbian Lite OS, there is some setup we must first do before we can run the command. We've split the below into sections so you can skip bits and jump around, and come back if you have any issues. We recommend setting up the software first so that the servos can initialise to be at 90 degrees, then commence assemble the pan-tilt bracket kit.

Firstly, we must download the latest version of Raspbian Lite. Head over to 

 and select Raspbian Buster Lite

If you're new to linux, or have only ever used NOOBS, and don't understand the "Buster" reference; This is to tie with the 

Debian Linux

 releases (as Rasp

bian

 is a variant of De

bian

). The actual name is chosen from 

A Debian 

Release

 is a version of all related software that are expected to work together. The next release in the near future will be 

bullseye

.

Next up we want to use a software program called 

BalenaEtcher

 to burn the raspbian image onto SD card. Head over to 

 and download and install. You should find that this is a pretty simple program to use.

Load up your Raspbian_Lite.zip you downloaded before, and select the right SD card, then press Flash.

Once it's finished, remove the card, put it in the pi, and boot it up.

When you first boot up the card, it might take a little while and will come up with "Resizing Filesystem" messages. Don't worry about that for now, it's just getting cozy in the SD card you used.

Once it's finished, you'll come to a login prompt, you can login with the below information:

Note, you will not be able to see the password when you type it in.

This part is to change the look of the console font.

You should be able to skip this section if things are fine, but you might get to a point where characters on the screen show up as squares, or maybe you just want a nicer looking font to work with.

Run the below command once you have logged in:

Select the below settings, Terminus being a useful programming font.

UTF-8

Latin1 and Latin5

Terminus

8x14

That should fix up most issues; You might have to try some Latin with Cyrillic if there's still squares, or post a screenshots in the issues tab of the project page on github.

Naturally, without a desktop it is a little less intuitive to set up the system and connect to things like the WiFi. Below is the raspi-config command and all the settings we have used in our setup for this project.

If you were to type " on the keyboard, you will realise that it comes up as @ - this is a fairly annoying problem on the raspberry pi, and is due to the creators being based in the UK.

Run the below command and set options as shown.

You can also set other localisation options, for things such as time and numbers, but it's not incredibly important for the time being.

Then press Tab and Right to select Finish, then reboot and log in again.

Once the system is set up, run the below commands.

As a point of reference, here is a list of all the things that the script will be doing:

setting the system to download files from australian servers (which is quicker).

running an update and refreshing what is installed.

Downloading the RPi_Cam_Web_Interface

unzipping, renaming, and copying the config file from before into it.

Installing the rpi cam interface.

Enabling pan and tilt in the interface

Installing the "driver" for the pan-tilt bracket.

Connecting everything up and getting it ready for boot.

Rebooting the system

You'll find that this might take a little while, but you should get a screen that looks like this:

This is just a collection of settings which you can just leave as default. The Cam subfolder will change the location of the web-interface to be in https://ip-address/cam-subfolder - it shouldn't hurt if you change it, but if it does, submit an issue on github.

Press Tab to select Ok and press enter, it will then download a tonne more packages.

(If you're really interested, you can find more information about the configuration options in the 

 section.)

Once that is done, it will ask if you want to start now; It doesn't matter what you choose as our script will reboot the system anyway.

The original pan tilt kit was designed for a different type of camera, however we can simply snip off the two clips and have a nice flat backing plate to mount the camera onto.

The first thing to do is to use the + piece from one of the servo packets and snip that to size so it fits inside of the base of the pan tilt kit, as shown below:

Once this is in, you can screw it into place with some small screws or use some super-glue (

) to hold it together

You can then attach the two halves onto the servo and clip them together, before placing into the base so that it looks like the below picture. There should be some screws in the pan-tilt bracket to screw the two halves together.

Do not screw the base hub to the servo yet! it will need to be adjusted to the right angle. If you reset the raspberry Pi, the servos should automatically adjust to 90 degrees.

Once the servos are at 90 degrees, then you can screw the hub into the base so that it is positioned straight.

The tilt bracket is easy enough as you can screw it to the back of the plate as such; notice how the single arm piece is coming out of the bottom of the bracket.

Once that has been done, you can then bend open the two halves from before and slip it in to place, so the final assembly should look something like the below image:

Make sure that the servos are at 90 degrees again, and push in the final servo arm piece into the space as shown on the picture. You will have to snip it down to size so that it can fit.

Once that has been done, you can use 

, 

, or 

 to mount the camera onto the plate; Make sure that the cable has full range of movement, as shown in the picture below. We bent the camera cable to come from out the

Also note

 The pinout in the picture above is incorrect, you need to connect the servos to pin 16 and 18.

Connect the camera into the camera connector on the rasberry pi, then attach the gpio shield ontop of the pi; We made the camera cable come out the back, near the ethernet port, so that there's more room for the pan tilt bracket to move around with the camera attached.

Connect the servos so that the red wire is connected to power, brown wire is connected to ground, and the yello wire is connected to the data pin, on the pinout table as below:

If you want to change the pinout locations, you can do so by editing /etc/init.d/servoblaster.sh once the system has been installed.

At the end of the installation, you should find your pi IP address, for us, this is 10.0.100.149 but yours might be different. You should be able to capture a glimpse of it when you boot up the system, but if not you can simply run the ifconfig command to find out:

Because we are connected to WiFi, we are looking at the wlan0 interface, and can see the inet is set to 10.0.100.149 on our setup here, but it could be different on your network.

Go to another computer in your house, you should be able to access https://10.0.100.149 in your browser and find that you have a fully operational camera system; If you have opted to put it into another subfolder in the initial setup, you'll find that folder present in the index, such as https://10.0.100.149/camera.
