Mobile Camera as CCTV is a free Android app developed by Usman Ahsan that allows you to use your old or unused phone as a security camera. The app requires both the sender and receiver phones to be connected to the same Wi-Fi network, though the developer is working on making it compatible with different networks.

This mobile client software can be used to remotely monitor your room, laptop, or any other space via a wireless network. You can easily set up the camera and monitor it from another device. The app is compatible with Android OS versionor higher and requires at least one Wi-Fi, 2G, or 3G access service to be supported by the phone.
