To set up an old phone as a remote camera in the house, you will first need to download a security camera app on the phone. There are many apps available for both Android and iOS devices that allow you to use your phone as a remote camera.
Once you have downloaded the app, you will need to follow the instructions to set up the camera. This will likely involve creating an account, connecting the camera to your home Wi-Fi network, and positioning the phone in the desired location.
Once the camera is set up, you can access the live feed from the phone on another device, such as a computer or tablet, using the app. You may also be able to receive alerts and notifications when motion is detected or set up recording schedules.
It is important to note that using an old phone as a remote camera may not provide the same level of security and features as a dedicated security camera system. However, it can be a cost-effective way to monitor your home and keep an eye on things while you are away.
