Alfred is an interesting home society camera app that transforms your existing Android devices into stationary cameras. To fully take advantage of everything this app can do, you would need at least two Android devices, and one of those devices would essentially have to be devoted to becoming the stationary security camera. An older phone that you no longer connect to any network would work for this since it only requires access to your WiFi network.

One of the most useful features of this software is that it can be used simply as a motion detector. With this mode, your camera will only activate when it has detected motion. You will also receive a notification on the phone that you're using to monitor the surveillance phone. To make this feature work optimally for your situation, you can change the sensitivity of the motion sensor and the amount of video that will be saved after the camera has been activated

The phone that you'll end up using as the camera for your system can be plugged in at all times so you won't have to worry about monitoring battery life, and it should remain constantly connected to the internet for the system to work.
