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 couldnāt 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. 
Letās 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 mountainās house and I donāt 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, Ā and in case that something goes wrong, I had to make sure that I can access to the camera and fix it.
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. Iād 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 reallyĀ 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 andĀ attached one servo on the top to move the wholeĀ structureĀ and the second to move the camera up and down.
