Your old iPhone can become a security camera — but subscriptions change the maths

An unused smartphone can provide live streaming, motion detection and two-way communication, although annual app fees may eventually make a dedicated camera better value.

Repurposing an old phone can be a practical alternative to buying a dedicated security camera, particularly when the device is already sitting unused in a drawer. In one example, an old iPhone was turned into a monitoring device after the author found that choosing a new camera meant weighing resolution, cloud plans and other features that were unnecessary for a simple home setup. The appeal is clear: a forgotten handset still contains a camera, screen, battery and wireless connectivity, which is enough for basic surveillance tasks.

The chosen app was Alfred Camera, which is designed to convert old smartphones into security cameras. According to the app’s listing in Apple’s App Store, it supports live streaming, motion detection, two-way communication and night vision, and works across both iOS and Android devices. Alfred’s own support guidance says setup involves installing the app on two devices, assigning one as the camera and the other as the viewer, then pairing them with a QR code and completing the on-screen prompts.

In practice, that makes the system easy to adapt for several uses. The feed can be checked remotely from a main phone, which means it can serve as a pet monitor, a baby monitor, a porch watch or a basic garage or car check. The article describes using it to see when a cat wanted to come back inside, but the same arrangement could be placed elsewhere in the home or even near an entrance. A small tripod and a constant power source help make the setup more stable, especially if the phone is expected to run for long periods.

The main drawback is cost once the user moves beyond the free tier. The article says Alfred Camera offers Standard and Plus subscriptions priced at £35.95 a year and £44.95 a year, with cloud storage and support for more cameras included. That changes the value equation. While the app may be inexpensive at first, annual fees can make it costlier over time than a standalone home security camera, many of which are sold as one-off purchases. That is a significant consideration for anyone comparing it with budget options from brands such as Tapo.

There are also alternatives. A free iOS-only option mentioned in the article, Oriel , Home Security Made Simple, is still in early development and does not yet have an Android version. Other guides from Android Authority and Technowifi make the broader point that old phones can be useful as low-cost surveillance devices, and that the approach may also reduce electronic waste by extending the life of hardware that would otherwise be discarded. For anyone already owning an extra iPhone, the idea is worth considering: not because it is always the cheapest long-term answer, but because it can turn existing kit into something genuinely useful.
