[b]Are you feeling hunted by ghost ? ,insecured or you dont know how your chicken keeps disappearing from your Refrigerator. Its time to clear that doubt.
Do you have an old/ignored andriod phone or tablet ?, Make it useful ,as a private security officer.
There are various types of application to use.
But will rec·om·mend:

┅ IP Webcam
┅ Motion Detector Pro
┅ Surveillance cam
┅ Motion spy video recorder
┅ Icam spy
And even your famous skype,by activating the auto answer
(note:skype is not a security application but for video/voice call and also texting, so it doesn't have the main feautures of security application like email alert etc)

To begin you have to have an active data bundle and a good battery on both devices, then download any of the application above or any of your choice at google play store or an Alternative android market.
After downloading setup the application to your choice of use.
Whats amazing about the applications it has

┅ EMAIL ALEART
i.e you get a direct alarm email when any movement is noticed around the camera view.

┅ SHORT OF DATA ?
You can activate the snap/video and store on the device,meaning the application stores the information of the intruder in a hidden folder in the device.

┅ MOTION / FACE SENSORY TECHNOLOGY
The application also offers a secured way of keeping you safe, via motion sensory the application stops and quits recording when the device is noticed or picked up by the intruder, without it,him/she or he and she suspecting what the appliction have been doing.

┅ FAKE SCREEN
The application also fakes its screen while recording or taking pictures of the intruder.

┅ E.T.C
Its also comes with special features like
Password lock, siren , sound dection and so on, varies depending on the application you downloaded.
The feautures are amazing even if it does not meet up to the standard security camera.

******HAPPY NEW YEAR, BE SAFE*******[/b]
