A few months ago I decided to take as a freelancer, work from home it would allow me to reconcile with the studies that I cursaré distance next year; After a period of inactivity for lack of time I return stomping.
One of the projects that I have developed and implemented in this period of time is one of the parties, but improved, of my end-of-course project: a video surveillance system free based on Raspberry PI.
After many hard and difficult days and nights of litres and litres of coffee, Since I've been learning what is necessary in terms of programming and LOPD on the fly and self-taught, I want to share with you finally the result of much effort.
The system designed to measure for the pilot store consists of five cameras video surveillance with night vision expandable in angle and distance, sensors presence detect, and a uninterruptible power supply that acts as a battery in case of power outages with a duration of up to three hours, correcting also the shortcomings of the power thus preventing possible damage in the hardware by the same.
For obvious reasons I can not hang nearly any image extracted from systems implemented in real stores, at least not those taken during opening hours or which allow to get an idea of the distribution of the shop in question, or the angle of approach to the cameras; i.e., the actual extent across his goal and filters chosen for each specific location of the establishment.
The images are stored in a centralized recorder, and can be found the records in video format as well as the images from the cameras in real time from the interior of the establishment or domicile, as on public roads Since operating systems Android, iOS, Windows, Linux and MAC OSX.
I've written a simple Demon system for the purpose of notified by a bot that I programmed for Whatsapp the person in charge of the establishment of presences unauthorized in closing time to the public, so you can see images of the exact moment of intrusion; It is also possible to configure alerts via email.
All devices receiving power from the same source, supplied by the voltages required for each of them taking into account possible voltage drops produced by the length of the wiring, that on occasions it can measure up to one hundred meters, Since both data and power travelling through the same cable thus reducing the time and resources needed.
There is the system of a centralized control panel from which view images in real time, Download the videos stored in the recorder, and check the status of devices System, as well as configure them.
