MyPhone CCTV

< Basic explanation >

1. The local hotspot can be used as a CCTV by connecting a mobile phone and a mobile phone even on a smartphone without a SIM card.

2. It has a built-in streaming server, so if you connect the remaining smartphone to the router at home, turn off the screen after connecting the power, you can access it with another phone from the outside and watch the video like CCTV.

3. I think it can be used as a black box because it can be recorded without a smartphone Internet connection.

4. CCTV is operated on a mobile hotspot (Wi-Fi) without a smartphone Internet connection.

5. The video is H264 + AAC (MP4) configuration and is encoded (compressed), decoded (uncompressed) in hardware using MediaCodec.

6. If you want to set the video resolution higher, adjust the bit rate (quality) higher and you can adjust it by selecting various numerical values.

ex) Video resolution: 1920x1080, video bit rate: 1000000 (1MB/1 sec)

7. If the streaming server is running by pressing the [START SERVER] button, click the [START STREAM] button to start the camera and click the [MULTI PLAY (10)] button to view the video.

8. Share files from FTP (File Transfer Protocol) servers and clients.

9. Run a web server (lighttpd, php8, sqlite3) on your phone.

10. 7zip support - 7z, arj, bz2, gz, rar, tar, tgz, zip, xz, bzip2, gzip, wim, iso, apk

11. Provides real-time chat with Wi-Fi or mobile hotspots without an external Internet connection.
