Forgotten old mobile phones at home can gain new use as video surveillance cameras. Through specialized applications, it is possible to turn them into security devices, remotely controlled by another smartphone, tablet or computer with internet connection. Learn now more in this article.
According to the Spanish Economist Economic Journal, this process of turning old mobile phones into video surveillance chambers is simple, free and accessible to any user, not requiring advanced technical knowledge. The solution involves only two mobile phones: the old one, which will serve as a camera, and the current one, which will function as a receiver.
Applications that facilitate the process
Among the most popular applications, cited by the same source, to turn old mobile phones into video surveillance cameras, Alfred Camera stands out for free for Android and iOS. The app allows you to activate motion alerts, record videos, watch live images and even communicate by audio with those on the other side of the chamber, as if it were an intercom.
To work, both devices must be associated with the same Google account or ID Apple, which ensures a safe connection. The ideal is to keep the old phone connected to the electric current to avoid failures due to lack of battery.
There are also alternatives such as manything, presence and IP webcam, the latter exclusive for Android. All offer similar features, with different free or paid plans, depending on the user’s needs.
Adaptable and versatile surveillance
These systems can be used not only to watch the house, but also to monitor babies, pets or buildings of buildings. The quality of the cameras of many smartphones, even old models, is often higher than the low -cost IP cameras, explains the same source.
The security security transmitted is guaranteed through encryption and, in many cases, authentication of two factors. The main applications of this type ensure that access is reserved only to the authorized user, reducing risks of intrusion.

A useful solution also for business
This system can be equally practical in commercial spaces such as coffees, grocery stores or small offices. Allows you to watch specific zones without investment in new equipment, which can be especially relevant to limited businesses.
According to data from IDC consultant, cited by more than 1.5 billion smartphones were sold in 2023 worldwide. The average replacement rate of these equipment ranges from 24 to 36 months, which means millions of functional devices are set aside annually.
The reuse of these devices prolongs their useful life, avoids waste and contributes to reducing the production of electronic waste, which grow a worrying pace in Europe. Only 40 percent are recycled, according to data from the European Environment Agency.
CIRCULAR ECONOMY IN ACTION
This solution is part of the principles of circular economy, which promotes the reuse and appreciation of products before their disposal. The Ellen MacArthur Foundation is one of the entities that advocates the practical application of this model to the technological sector.
In addition, you can install more than a mobile phone in different divisions, creating a home surveillance network. Modern applications allow you to manage multiple devices in one account, without technical complications.
Compatibility with home systems (homework automation such as lights, safety and climate control for greater comfort and efficiency) can also be an additional advantage. Some applications interact with sensors, lights or alarms, providing greater control over the residential environment.
Temporary and educational solution
This type of configuration can also be useful in temporary situations such as travel or short -term rentals. Smartphone flexibility allows them to adapt to new locations as needed at no extra cost.
In an educational context, devices reuse has been encouraged in schools and training centers. Students learn to configure simple technological systems and develop environmental awareness at the same time.
Many Europeans keep old mobile phones at home
An article published by SAPO TEK on November 28, 2023, based on Eurostat data, indicates that 49% of Europeans keep old mobile phones at home, while only 10% send them to recycling.
This data highlights the tendency of many users to conserve their old devices, even after the acquisition of new models, which, often forgotten in drawers, represent a potential underproved with immediate practical value.
