Une caméra de surveillance vidéo avec le Raspberry Pi

Une caméra de surveillance vidéo avec le Raspberry Pi
C’est un projet de Christoph BUENGER. Bien documenté et décrit en détail, ce projet propose la réalisation d’une caméra de vidéosurveillance à base de Raspberry Pi. L’objectif de Christoph est de réaliser une caméra qui se déclenche si elle détecte un mouvement. Le prix doit rester raisonnable (d’où l’utilisation de la framboise314) et le flux vidéo est diffusé sur un PC ou sur un smartphone. Attention Ce tutoriel date de début 2014… il fonctionne sous Raspbian Wheezy. Je vous propose la traduction de cet article, pour permettre aux francophones de bénéficier de cette réalisation de Christoph. D’autre part si vous souhaitez recevoir un mail en cas de détection, vous pouvez lire cet article qui complète bien la caméra de surveillance : Tout compris, vous devriez tourner à moins de100€.

Test de la caméra Raspberry Pi 5M Raspberry propose depuis peu et pour moins de 25€ une caméra dédiée à sa gamme Pi. Cette caméra de quelques grammes se connecte à une Raspberry Pi (model A ou B) à travers une interface CSi v2 (MIPI camera interface) dédiée. Grâce à Kubii (fournisseur Farnell en France) j'ai pu obtenir rapidement un de ces caméra que nous allons tester dans ce billet. Avec un capteur d'une résolution native de 5 mégapixels (5M) et au niveau optique d'une lentille de focalisation fixe, la caméra peut servir d'appareil photo (résolution maximale de 2592 par 1944 pixels) ou de caméra vidéo (format HD juqu'à 1080p). Son poids est impressionnant car elle ne pèse pas plus de 4 grammes pour une dimension de L25 l20 H9 (en millimètre). On commence par brancher la caméra sur l'interface CSi. Il faut disposer d'une distribution Raspbian à jour avant de pouvoir activer la caméra: sudo apt-get update && sudo apt-get upgrade Un reboot plus tard vous pouvez commencer à jouer avec la caméra raspistill -o image001.jpg

The Eagerly Awaited Raspberry Pi Display You’ve been incredibly patient: thank you. The official Raspberry Pi touch display is on sale today, priced at $60 (plus local taxes and shipping): you can buy it at RS Components/Allied Electronics and at Premier Farnell/Newark. Other sellers will be receiving stock later this week. We gave one to Alex Eames of RasPi.TV a couple of weeks back so that he could give us one of his famously clear video introductions: Two years ago, I began the process of looking for a simple, embeddable display for the Raspberry Pi. Display Technology First of all, here’s an overview of the technology involved in the different types of display that the Raspberry Pi can support. Currently the Raspberry Pi can support the following display interfaces: HDMI is the system we all know and love, it allows us to communicate with monitors up to 4K and has a relatively low signal swing to reduce EMI. DSI (Display serial interface) is a high-speed serial interface based on a number of (1GBits) data lanes. 2) USB link

Webmin Guide After losing this the first time round by closing the wrong tab, it's time for a Webmin guide.This assumes you're running headless over SSH and want to be able to easily manage your Pi server with a GUI. Webmin is perfect for that job.So, firstly let's get all the dependencies etc. out of the way. We need to start by fixing user permissions then installing LAMP. Code: Select all sudo groupadd -f -g33 www-datasudo apt-get updatesudo apt-get install apache2 php5 libapache2-mod-php5sudo apt-get install mysql-server mysql-client php5-mysqlsudo apt-get install phpmyadminsudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl apt-show-versions python When you're asked for a password, use something that isn't insecure but something you won't forget either. mkdir webmincd webminwget webmin-1.580.tar.gztar xf webmin-1.580.tarcd webmin-1.580sudo .

Raspberry Pi devient une console rétro X windows session over ssh on Mac/Linux Hi, I'm sure everyone knows how to do this, but I see a lot of people running tightvncserver to run an X session remotely whereas running X over ssh is much more efficient as the poor old Pi doesn't have to do as much compression and/or drawing the screen. On a mac (and linux) it's just a matter of running the command Code: Select all ssh -X pi@YOUR_PI_IP_ADDR Your Pies(?) ifconfigOUTPUT:eth0 Link encap:Ethernet HWaddr b8:27:eb:bc:d7:79 inet addr:192.168.2.3 Bcast:192.168.2.255 Mask:255.255.255.0 Once logged into your Pi, you will notice the usual pi@raspberrypi prompt, plus an X session will start on your Mac. Try xeyes To run a complete session, type lxsession into the ssh window to start a LXDE session on the Mac (but running on the Pi). Sound works (it comes out of headphone socket) if you do a sudo modprobe snd_bcm2835 To quit, it's best just to do a 'sudo reboot' otherwise things get confusing, though you can ctrl-c the original terminal to terminate the lxsession.

GPIO Zero A simple interface to everyday GPIO components used with Raspberry Pi. Created by Ben Nuttall of the Raspberry Pi Foundation, Dave Jones, and other contributors. Latest release The latest release is v0.9.0 beta 4 released on 25th October 2015. About With very little code, you can quickly get going connecting your physical components together: from gpiozero import LED, Button led = LED(2) button = Button(3) button.when_pressed = led.on button.when_released = led.off The library includes interfaces to many simple everyday components, as well as some more complex things like sensors, analogue-to-digital converters, full colour LEDs, robotics kits and more. Install First, install the dependencies: sudo apt-get install python-pip python3-pip python-w1thermsensor python3-w1thermsensor python-spidev python3-spidev Install with pip: sudo pip install gpiozero sudo pip-3.2 install gpiozero Both Python 3 and Python 2 are supported.

Turn Your RPi 3 Into a BLE Beacon With the launch of the Raspberry Pi 3, Bluetooth Low Energy (BLE) is now at our disposal. With BLE, there are a few technologies for implementing one-way beacons that broadcast data. Apple has been pushing iBeacon since 2013, and Google just launched their Eddystone solution last year. If you’re looking to target Google’s Eddystone on your RPi 3, [Yamir] has you covered. He’s put together a guide on setting up an Eddystone-URL beacon within Raspbian. The process for setting this up is pretty simple. Framboise 314, le Raspberry Pi à la sauce française…. | Le Raspberry Pi, un ordinateur à 35€ ? Je demande à voir !
