A good selection of apps is available for Android users to repurpose their devices as security cameras capable of remotely updating you when intruders are detected.
Old webcams for smartphones: not new
As long as there is a suitable application to convert your device into an IP camera, you can use it. This is also a great way, as the software you choose to view your webcams can be configured to alert you when motion is detected.
However, for a limited approach that does not require a central PC to manage channels and store images (potentially using up valuable hard disk space), Salient Eye is a strong alternative.
But hold on, this is not a webcam!
Salient Eye, available for free on Google Play (an iOS version is planned, see www.salient-eye.com for details), does not provide the usual IP camera functionality that is expected from security camera applications. Instead, the app takes photos and plays a fairly loud alarm when motion is detected. The images are then saved to your device and you can provide an email address or SMS number to send them.
Compatible with both Android smartphones and tablets, Salient Eye is also capable of low-power operation for up to 10 hours on your phone’s battery and remains active when the display is off. You can see in the image above where it detected the objects highlighted in red and distinguished them from the wall. Any change in these items and motion detection will raise an alarm and send an email.
Setting up a security camera for your smartphone with Salient Eye is very easy.
