What’s the setup process like?
Make sure you have your new phone and your old phone
After you have both phones logged in, make sure that yourold phoneis designated as theCameraand yourcurrent phoneis designated as theViewerdevice. Your old phone will ask you to give the app access to use its camera and microphone sensors, which you’ll need to permit for the software to do its job.
Make sure both phone screens are turned on, and then tap onWake Up Cameraonce the button appears on-screen. At this point, on your currentViewerphone, you should be able to see the video and audio stream being recorded via your oldCameraphone.

you may rename the video feed to whatever you’d like, or you can choose from presets likeOfficeandBaby’s Room.
If your old phone is running Android, then follow the on-screen prompts to allow Alfred toDisplay over other apps. Granting this permission will allow you to turn off the screen of your old phone, even while it’s acting as theCamera. The video and audio feed will continue to work, even while the display is off and the phone itself is locked.

During the setup process, the app might also prompt you to switch onActivity Detection. As the name suggests, this feature will send a notification to yourViewerphone whenever movement is detected from yourCameraphone. You’ll receive these notifications even while the screen is off, and even if you’re not actively watching the video feed. This feature can be toggled on or off at any time to match your preferences.
Some additional considerations
Think of the battery life and an alternate power source
It should be noted that using a phone as a security camera is fairly battery-intensive. If you plan on leaving the video feed on for an extended period of time, you’ll want to invest in a charging cable to avoid battery drain.
Many people like to use the video feed as a baby monitor, while others prefer to use it to monitor their front door.

Where you choose to place your old phone and point its camera towards is entirely up to you. Many people like to use the video feed as a baby monitor, while others prefer to use it to monitor their front door.
If you happen to have a small phone-sized tripod or similar accessory lying around, you’re able to use it to prop your phone’s camera in the right direction. AQi2 wireless chargingstand might also do the trick.
Be aware that the additional heat generated from inductive charging might do a number on the health of your old phone’s battery pack.
Some of the apps on the market, including Alfred, also offer the ability to connect to external purpose-built security cameras. The cost of these cameras varies, based on factors like optical quality and the feature set provided. If you fancy the idea of monitoring your back garden or somewhere else outdoors, using your old phone isn’t advisable for this task. You’ll want to invest in a weatherproof camera that can be mounted and bolted in place to prevent theft.
