Don't throw away that old phone: turn it into a spy camera for your home with this setup

The process is simple, secure, and completely free. Thanks to specialized applications, an old phone can be converted into a video surveillance device that can be controlled from another phone, tablet, or even a web browser. This represents a considerable savings compared to purchasing traditional security systems, which can easily exceed 200 euros .

One of the most recommended options for its ease of use and functionality is the Alfred Camera app , available for both Android and iOS. This app allows you to use one device as a transmitting camera , while another acts as a surveillance monitor.

1. Download the app on both devices : The first step is to install the app on two phones: the old one, which will function as a camera, and the current one, which will act as an image receiver.
2. Sign in with the same account : Both devices must be signed in with the same Google account or Apple ID to securely link them.
3. Put your phone in the right place : The next step is to place your old phone in a strategic location: on a shelf in the living room, in the entryway, in the baby's room, or even inside the car. Ideally, it should be plugged into a power outlet to prevent the battery from running out.
4. Set up motion alerts : Most of these apps allow you to trigger instant notifications when motion is detected, record automatically, and even talk through your phone like an intercom.

In addition to cost savings, these solutions stand out for their versatility. The quality of the mobile phone's camera, which in many cases is superior to that of a low-end IP camera , allows for clear images both day and night (if the device has night mode or is installed near a light source).

Another notable advantage is the ability to access the camera in real time from anywhere in the world with an internet connection, making the mobile phone a highly effective security tool.

According to data from the consulting firm IDC, more than 1.5 billion smartphones were sold worldwide in 2023, while the average device renewal rate is between 24 and 36 months. This means that millions of phones with functional cameras end up unusable before their useful lifespan is reached.

Using them for purposes such as surveillance, home automation, or home security not only saves money but also contributes to reducing the generation of technological waste, aligning with sustainable and responsible practices.
