Presence has a web portal as well, but it has limited capabilities: It can’t view live streams and can only see videos recorded Getting started with Presence is ridiculously simple: Just download and install the app on both devices, set up an account, and give it permission to access your device’s camera.

Each device can be used interchangeably as a camera or monitor, and you can connect as many devices as you like to your account.

Audio streaming is clear and crisp, though it can have a lag of up to two seconds.

From the monitor device, you can start a two-way video/audio conversation with the video device.

For long-term monitoring, the app records five-second video clips whenever it detects motion.

This way, you don’t have to be constantly watching the stream to catch any action. When you connect to i Cam Spy to view your surveillance feed, the app asks if you want to view the feed in Wi-Fi or 3G/4G mode.

i Cam Spy isn’t free, but its polished interface and excellent video capabilities make it worth the $4.

Once you’ve downloaded and installed the app on your Android device, registering is a snap (all you need is an email address and a password).

You can also dim the screen to help save battery life, though you should probably keep your camera device plugged in if you’re going to be streaming for a while.

To view your live stream on the monitor device, open up the Presence app and tap the camera device’s name under the “Remote Cameras” section.

Keep in mind that i Cam Spy is a surveillance app, not a baby monitor.
