Video Surveillance HD: Raspberrypi + PiCam + Android

The video-surveillance field is active many years ago, but there is only products that show image and little else. It's need to add intelligence to surveillance tasks. We are committed to create technology to care for people and avoid dangerous situations. For this we have created a surveillance solution with high intelligence.

· Do you want to know if your baby stands or falls from the crib as soon as possible? Even at night without lights? · Do you want to know if your baby leaves the room game or leaves the house? · Do you want to detect if someone is close to the cash register? · Do you want to create alarms in 3D space to keep your staff safe?

We are working with intelligent sensors to detect these situations and send alarms to the smartphone. These intelligent sensors allow us create 3D alarms in a house/office and provide a safe environment 24 hours per day.

For the moment, the first prototype of surveillance shows how it's possible access to RaspBerryPi with PiCam using and Android tablet. We are using a standar HD camera without night vision to offer a standar solution for daily situations.

Show your RTSP video in Android with VLC

If you have developed an Android app with video streaming, I'm sure you notice that Android use a pre-load of video buffer that fills in 10 seconds. This delay is hardcode in the source code. It's very hard create a real time app to show video with this delay.

There are several solutions out of android to show video streaming. Some of them provide SDK to develop. But if you don't want develop to other SDK, you can use VLC for android. Thanks to the intent's communication of Android, we can interact with VLC Android app.

Android SDK 64bit and Debian amd64

As you know, it's possible download the Android SDK for 32 and 64 bits architecture.  If you choose 64bit architecture you notice that some binaries are compiled to 32bit architecture

vega:$/android/sdk/platform-tools$ file aapt
aapt: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically 
linked (uses shared libs), for GNU/Linux 2.6.8, not stripped
Installing ia32-libs package was enough to solve this problem, but this package doesn't install correctly in debian sid. It has been replace by Debian-Multiarch (more…)

Making screencast for Android classes

I need to record some screencast with audio for my online classes of Android. It's a good way to explain all the topics about programming and android development. Slides, exercises, moodle and screencast is a cool combination to create high-quality online courses. Also I use a digital tablet to write in the desktop/slides to clarify the explication. Finally I'm used to manage openShot as video editor, it's simple and very powerful.

I use the following ffmpeg command to record screencast (audio+video) of the desktop and Android emulator:

The first prototype video of ESTUFA

ESTUFA is a framework that provides several ways to connect and re-use mobile applications (in previous post I already presented this idea). The system allow build “execution chains” to connect and plumb two applications. This project is based in the idea of re-use and compose new applications using components (in this Read more…

Arduino & Android & ADK

The last Google I/O a new feature based in Android and Arduino was released. The ADK allows the communication between Android and Arduino using a USB connection. Google have developed a library called “USB Accessory” in Android and Arduino. So, this library help us to send and receive data through USB interface. Using Read more…

New challenges about Android, AR and Arduino

During the next months I will work in three interesting topics. The first of them is the creation of a new architecture based in Android that allow communicate and integrate applications. The second  is the port of ARviewer to iPhone platform using phoneGap. And the last one is the very well-know Arduino and Read more…

Kinect’s depth map on your Android device

Two weeks ago, I have received the new fashion gadget of Microsoft: the kinect sensor. Thanks for the community (libfreenect), this sensor designed for Xbox can be used in GNU/Linux systems. Lately I have the need of integrate anything with Android mobile (is it because I have over 3 years programming with Android?) Read more…

AR interface in Android using phoneGap

Since 6 months ago we have evaluated the possibility to implement a new AR interface (based in our project ARviewer) using phoneGap. phoneGap is a mobile framework based in HTML5/JS that allow execute the same source code HTML5 in differents mobile platforms (iphone, android, blackberry). It seem a good way Read more…
