A spare phone becomes a free security camera with AlfredCamera

The article describes a practical way to give an old phone a second life as a security camera. The change is that a device previously sitting in a drawer can now serve a functional role with minimal effort. The setup involves installing the free AlfredCamera app on both the old phone and a primary phone, then pairing them via account login or QR code. This turns the old phone into a camera and the primary phone into a viewer, all without any wiring beyond the charger.

Adopting this approach costs little upfront, but there are trade-offs. The free plan limits users to two cameras and lacks HD streaming, recording loops, and cloud storage beyond what the premium tiers offer. To get person, vehicle, or pet detection and longer recording, a subscription starting at $5.99 per month is required. Additionally, the old phone must stay plugged in and connected to Wi-Fi, which may constrain placement and increase electricity usage over time.

The solution stops working well when the phone's battery degrades or the operating system kills the background app. The article advises disabling battery optimization for AlfredCamera to keep it running 24/7, but this may not be sufficient on all devices. For outdoor placement, weather-proofing is necessary, and the article suggests mounting the phone inside a window instead. A factory reset is recommended to clear personal data, which is a critical step given the device will be continuously connected to the home network.

This is a single-feed story, so there is no independent corroboration of the claims. The article is a how-to guide rather than a news event, and the headline is a suggestion rather than a product announcement. Engineers evaluating this approach should treat it as a DIY solution with known limitations, not a replacement for dedicated security systems. The value lies in repurposing existing hardware, but the operational constraints and subscription costs should be weighed against the benefits.
