Very cheap way to implement home surveillance camera.
All you need is:
– old Android phone
– home wifi router (I assume this should already be in every apartament)
– access to some free DNS service (I use http://www.noip.com/free)
Install application from Google Play
https://play.google.com/store/apps/details?id=com.pas.webcam
The configuration is very straight forward. Assuming your phone is configured to use your home WIFIyou should be able to access your streaming right away – just type on your computer the address (something like 192.168.1.xx:8080) and after selecting desired streaming technology you should see your stream. The next step would be to forward traffic from your router to your android phone:
Configure port forwarding on your router
There is a great page that will help you do that – I don’t want to write my own tutorial if something that great is available http://portforward.com/english/routers/port_forwarding/default.htm Just find your router brand and model and follow the steps. IP Webcam by default works on port 8080 so you need to forward your android phone ip port 8080 to some external port on your router like 8081 for example. The problem at this point is that you would need to know your routers external IP address to access it from internet. Of course you could check the ip on one of the pages http://whatismyipaddress.com/ or better http://www.moanmyip.com/ but that is typically changing (depending on your ISP of course). To get access to your router from internet you need to:
Configure your router to register on one of the free DNS services
This way you will be able to access your camera IP Webcam from anywhere. Here is good link that should get you started http://www.tp-link.com/en/article/?faqid=419 of course if you are using different router brand the configuration will be slightly different, but the principle should remain the same.
Assuming your domain will be something like “myself.no-ip.com” your camera should be available under myself.no-ip.com:8081
enjoy
