Since smartphones are getting better and better, people upgrade before their old phones die. Consequently, old or outdated devices are taking up space and just sitting around.

You should keep reading to find out how you can accomplish this.

How to Turn an Old Phone into a Security Camera?

Put a third-party security app on your old phone and start monitoring it. Despite the fact that this setup is pretty straightforward as you can see, it is quite simple. 

1- Preparing Your Old Phone

Start by removing the old phone that you are no longer using and using your current phone. Your current phone can be used as the viewer, and the old phone as the camera.

2- Installing Camera App

Apps for security cameras are available in the app store for your mobile device. A good security camera app includes essential features like remote recording, streaming, two-way audio, and motion detection.

3- Pairing Your Devices

Once the app is installed on both phones, open the app and log in to your account. Make sure both phones have the same account, otherwise they will not connect. Use the old phone as the camera, and the new one as the viewer.

4- Choosing Perfect Placement

Place the Camera in an area you want to monitor, such as the entryway, stairwell, or living room. In order to make the camera look good, it should be placed up high. This way, it can capture the area without getting knocked over by your kids. Cameras should also be angled appropriately to provide the best visibility.

5- Testing Your Setup

Don’t forget to make sure the camera stays powered and works. On the Viewer device, you will be able to view the camera’s live feed through the tap of the screen. Besides setting motion detection sensitivity, you can also turn notifications on or off.

6- Real Time Monitoring

By using this DIY trick, you can monitor your property without spending a fortune on security cameras. To get extensive WIFI coverage in your house, you can set up several old phones on the same network and account.

Disadvantages of Home Security Cameras

Monitoring drains your battery significantly, so keep the old phone charged. Security cameras are durable, whereas phones require frequent maintenance.

2- Low Resolution And Blurry Camera Footage 

Low-resolution cameras on old phones can’t record clear videos or capture clear images.

3- Lack of Advanced features And Limited Mobility

Even phones with security camera apps offer only monitoring, communication, and detection. Unlike security cameras, they can’t be integrated with smart home systems.
