Description This project was about a personal challenge that my Dad asked me to do it. Everything started more than one year ago when I was trying to do it with Arduino but I lost a lot of time because I couldn't make everything works as fast as Raspberry does. I decided to move on Raspberry PI and everything became easy and fast, in a few days I had made 70% of the project. Let's talk about the project, my idea was to create a remote webcam that I could control it over the 3G network, because I wanted to install it on my mountain's house and I don't have an internet connection. The camera have to be equipped with: 2 servos: move left/right and up/down from a web interface one temperature sensor: getting information and store them in a file one motion sensor: something like a little CCTV that will send me message and picture when someone is close to it Obviously everything have to be very well thought for any little problems, and in case that something goes wrong, I had to make sure that I can access to the camera and fix it. Raspberry : http://amzn.to/2pQXDUw Battery: http://amzn.to/2qeENrz Camera: http://amzn.to/2pRgkr5 Simple Schema Schema Web Interface I made a little website to communicate with the camera, I can move it LEFT/RIGHT and UP/DOWN by pressing 4 buttons. I can get the current temperature, start live streaming, change motion alerts and manager all files about camera pictures and some other files. I'd like to improve everything with a proper client side using another Raspberry Pi, small screen and a few buttons. 3G Modem I was looking for a good and cheap 3G modem that could work with Raspberry PI and read/send message, what I found was the HUAWEI E3131 that had a web interface and a simple API to control it. I made a little wrapper library that I could send commands from my Python code, something like: connect to 3G network, send message, read message, etc.. I really recommender this modem because it was cheap, unlocked and easy to use! Python library for HUAWEI E3131 Servo Pan and Tilt I had to build my own Pan and Tilt system because the position that I have chosen is not simple one. I came up with a solution to put everything in a PVC tube and attached one servo on the top to move the whole structure and the second to move the camera up and down. First prototype: Webcam I have used fswebcam to capture snapshot from the webcam and I made a little wrapper in Python to execute this command with specific parameters. Temperature sensor I have chosen the DHT22 as temperature sensor, because it was easy to hook up with Raspberry and I have used this sensor on my previous projects with good results. What I thought was to implement this sensor to store different temperatures through the whole year and have a little chart about the weather on my mountain. Motion sensor The motion sensor was attached to my Raspberry via one digital pin, there was a thread that was checking every 4 seconds if someone was there and send me two kind of alert: SMS and upload the picture. I have implemented some functions to remove any kind of alert in case that the motion sensor will be trigger for stupid reasons. AutoSSH This was my special army to access on my Raspberry even if I was connected to a 3G network, because you know that you can't open any port as you can do on your own modem. Basically I had to setup a ssh key to connect to my server without insert the password and create a system to active and de-active the session. I came up with an external service with Python that will start the service if the internal service was crashing. You never know if the main script will working properly or your thread will stop to work, so this was my second security system to access and fix it. External Power Raspberry has only one micro usb port to give power to the whole system, so I had to solder 2 wires directly to the board. I found the instruction on this website: http://www2.pmb.co.nz/blog/computers/raspberry-pi-direct-5v-power-wiring-modification/ to understand which pins were the 5+ and GND. I suggest to mount a fuse between the battery and the Raspberry, in case that something goes wrong and you don't burn your board. Solar panel The power source was a little problem because at 2'000 meters over the sea you don't have a normal power socket to plug your devices, so I bought a solar panel from EBay and a car battery. I have chosen the car battery because you have 2 years of warranty and I was looking for something very high capacity and I found one with 55mAh at 12V. Conclusion I am testing this configuration at home before move everything at 2'000 meters, so I can be sure that at least for a month I can connect to it, get some pictures and fix any crashes that will came up.
