  "account": "Abandoned mobile devices often end up unused in storage. Repurposing one as a video monitor is possible without reliance on the cloud. A three-year-old handset retains a capable sensor, Wi-Fi, and battery. Power consumption can be minimized by recording without displaying the screen. Android devices offer this feature through dedicated background camera recording applications or certain OEM camera apps with a \"screen off\" setting. Installation can be completed within a minute. Mounting the device at the desired surveillance point, such as a doorway or pet area, preferably on a power source as continuous recording will drain the battery quickly. A camera application supporting screen-off recording and live viewing over a local network connection is required. For later footage review, saving clips directly to the phone's internal storage suffices. If live viewing is desired, choose an application that streams video over the local area network to prevent cloud service fees and ensure low latency. Though LAN-only viewing restricts remote access, an optional VPN could mitigate this limitation. In comparing available options, Alfred Camera offers a free tier with limited capabilities, while AtHome Camera provides a free tier with up to 720p resolution. IP Webcam allows for local streaming with a more manual setup, and WardenCam, although effectually discontinued, was previously free. Background Camera RemoteStream is a recommended application that facilitates screen-off recording and live viewing over your own network, free of charge. Consideration should be given to heat generation as a potential issue when continuously recording, necessitating adequate ventilation and avoiding sealed enclosures in direct sunlight. Confirming the application's ability to maintain operation during screen sleep is also advised, as certain phones may terminate background processes. The Background Camera RemoteStream application is available on Google Play. For additional information, refer to the Superfunicular website. This straightforward procedure utilizing a discarded Android device can be accomplished in a short time, providing an affordable surveillance alternative.",
  "summary": "Old Android phones pile up in drawers. Instead of letting one die there, you can point it at a doorway, a driveway, or a pet's favorite corner and let it record. Here is a straightforward, cloud-free way to do it, and the reasoning behind each choice. Why an old phone is a good camera A three-year-old phone still has a decent sensor, Wi-Fi, and a battery. The two things that usually get in the…",
